Öğe Acute Subdural Hematomas Caused by Ruptured Aneurysms: Experience from a Single Turkish Center(Turkish Neurosurgical Soc, 2009) Kocak, Ayhan; Ates, Ozkan; Durak, Akif; Alkan, Alpay; Cayli, Suleyman; Sarac, KayaAIM: Although an aneurysmal rupture typically presents on computed tomography (CT) imaging as only a subarachnoid hemorrhage (SAH), it may be associated with spontaneous (nontraumatic) subdural hemorrhage (sSDH). The purpose of this paper is to discuss the clinical and radiological characteristics, as well as a potentially dangerous situation in the diagnosis and the management of this life-threatening condition. MATERIAL and METHODS: The Department of Neurosurgery at Inonu University (Turgut Ozal Medical Center) (TOMC) maintains a prospective database of all patients treated for intracranial aneurysms since 1999. Using this database, we obtained patients with ruptured aneurysms who presented with sSDH on CT imaging. RESULTS: 687 patients with radiographically documented ruptured aneurysms were admitted from January 2000 through January 2009. Of these, eleven patients presented with sSDH. The incidence of aneurysmal rupture with sSDH is 1.6% in our series. CONCLUSION: Acute sSDH on cranial CT should be considered for an urgent workup of a ruptured aneurysm, even in the absence or presence of SAH finding. CT angiography has advantages over cerebral digital substraction angiography (DSA) and may be a reasonable alternative to latter modality in the diagnosis, triage, and treatment planning in patients with sSDH.Öğe Angiographic embolization in epistaxis: Our clinical experience and results(2021) Cicek, Mehmet Turan; Yildirim, İsmail Okan; Bayindir, Tuba; Sarac, Kaya; Tan, Mehmet; Aslan, Mehmet; Ozer Ozturk, EbruAim: Nosebleed, more commonly called epistaxis is a general clinical problem, and the most of bleedings can be treated non-invasive approach. However, because of persistent and sometimes life-threatening bleeding, additional treatment such as super-selective embolization may be required. In this study, we report our data on the endovascular treatment of persistent epistaxis. Materials and Methods: Between January 2010 and December 2019, all patients who were followed up at Inonu University Turgut Ozal Medical Center Otorhinolaryngology Clinic due to recurrent persistent nosebleed and required endovascular treatment were retrospectively screened. Demographic data, cause of epistaxis, localization of the bleeding, the clinical significance of the bleeding, interventional approach, complications related to treatment, and results were evaluated. Results: All of 18 patients with intractable epistaxis were included in the study. Depending on the etiology of epistaxis, patients were determined into three groups: idiopathic epistaxis (10/18), iatrogenic or traumatic epistaxis (7/18), and nasopharyngeal cancer (1/18). Nine of 18 patients required blood transfusions. The internal maxillary artery was embolized unilaterally in 12 of 18 (66%) and bilaterally in 2 of 18 (11%) procedures. Four patients were not embolized because of bleeding originated from ethmoidal branches of the ophthalmic artery. These four patients were operated on (endoscopic ethmoidectomy and bleeding control). Long-term success rates of embolization were 14 of 14. Major complications (transient hemiparesis) occurred in one patient after embolization. Conclusion: Endovascular approach proves to be effective for intractable and fatal epistaxis. Embolization has a good risk-benefit ratio in persistent bleeding. However, if bleeding is originated by the ethmoidal branches of the ophthalmic artery, embolization may not be performed to avoid visual complications.Öğe Angiographic embolization in epistaxis: Our clinical experience and results(2021) Cicek, Mehmet Turan; Yildirim, Ismail Okan; Bayindir, Tuba; Sarac, Kaya; Tan, Mehmet; Aslan, Mehmet; Ozer Ozturk, EbruAbstract: Aim: Nosebleed, more commonly called epistaxis is a general clinical problem, and the most of bleedings can be treated non-invasive approach.

MATERIAL and METHODS: In this study, 124 patients with AComA and AComA-related anterior system aneurysms were retrospectively evaluated. The aneurysms were classified according to their morphological appearance and angiographic architecture. The size, size ratio, angiographic architecture, and aneurysmal dome orientation of ruptured and non-ruptured aneurysms were compared using digital subtraction angiography (DSA) 3D images. RESULTS: There was a significant relationship between rupture risk and the size ratio (p=0.043), morphological properties of the aneurysm (p<0.001), aneurysm dome orientation (OR 1.29, 95% CI 1.32-6.818), and aneurysm type according to the angiographical architecture (p<0.005). CONCLUSION: In determining the rupture risk of AComA and AComA-related aneurysms, size alone is not a sufficient parameter with aneurysm morphology proving to be more efficacious. Grouping of aneurysms according to angioarchitecture, and its significant correlation with aneurysm rupture, may help to understand the underlying mechanisms in the formation and rupture of aneurysms. From this, more specific treatment protocols can be created, helping to improve the clinical evaluation of AComA aneurysms.Öğe Brain MRS findings in neonates with hypothyroidism born to mothers living in iodine-deficient area(Karger, 2006) Akinci, Aysehan; Sarac, Kaya; Gungor, Serdal; Mungan, Ilke; Aydyn, Ozgur[Abstract Not Available]Öğe Cerebral MR Spectroscopy Evaluation of the Neuroprotective Effects of Lithium and Olanzapine in Bipolar Affective Disorder Patients(Universitatsverlag Ulm Gmbh, 2008) Cumurcu, Birgul Elbozan; Karlidag, Rifat; Sarac, Kaya; Unal, Suheyla; Ozcan, Cemal; Erkorkmaz, UnalAim: We used the NAA measurements obtained by cerebral magnetic resonance spectroscopy to evaluate the neuroprotective effects of lithium and olanzapine in bipolar affective disorder patients in remissions. Methods:Ten bipolar affective disorder patients on lithium treatment for the last six years and who had not experienced a manic or depressive attack for the last three years and were followed up at the psychiatry outpatients department were included in the study. The patients were evaluated while on lithium, 14 days after lithium was stopped and at the end of the 411 week following olanzapine initiation, for a total of three times. Each evaluation consisted of a psychiatric interview, the Hamilton Depression Rating Scale (HDRS) and the Bech-Rafaelson Mania Scale (BRMS) in addition to MR spectroscopy imaging. Results: The cases were compared with a control group consisting of 10 age- and sex-matched healthy subjects. We measured the N-acetyl aspartate (NAA) peak quantitatively in the right dorsolateral prefrontal cortex (DLPF) and left hippocampus areas on MR spectroscopy and checked the ratio to the creatine (Cr) peak. The values from all three imaging studies were compared with each other and with the control subjects. Conclusions: There was no statistically significant difference between the NAA/Cr ratios of the patients receiving lithium, those not on medications or those receiving olanzapine and the healthy subjects. We did not observe any change in cerebral NAA levels following lithium and olanzapine treatment in bipolar affective disorder patients in remission.Öğe The effects of hesperidin on idiopathic pulmonary fibrosis evaluated by histopathologial-biochemical and micro-computed tomography examinations in a bleomycin-rat model.(Allied Acad, 2016) Gormeli, Cemile Ayse; Sarac, Kaya; Ciftci, Osman; Timurkaan, Necati; Malkoc, SiddikIdiopathic Pulmonary Fibrosis (IPF) is a chronic, progressive parenchymal lung disease. The pathology is characterized by recurrent injury to microscopic alveolar epithelial cells. These injuries activate inflammatory cells, resulting in the proliferation of fibroblasts and alveolar tissue damage. Interstitial inflammation, advanced oxidative stress, and abnormal antioxidant activity were demonstrated to be the main causes of IPF. Hesperidin (HP) is a bioflavonoid with anti-inflammatory, antioxidant, anticarcinogenic, and analgesic actions. HP may be able to prevent pulmonary fibrosis, and may ultimately lead to healthy lung function. We hypothesized that HP could prevent Bleomycin (BLC)-induced pulmonary fibrosis due to its biochemical, antioxidant, and anti-inflammatory properties and may ultimately lead to healthy lung function. Based on these findings, we hypothesized that HP could prevent BLC-induced pulmonary fibrosis due to its biochemical, antioxidant, and anti-inflammatory properties. The animals were divided into 4 groups with 14 rats per group. The experimental treatments were as follows: Control, BLC, HP, and BLC+HP. Six of the 14 lungs in each group were sent for micro CT analysis. The remaining 8 lung specimens were harvested for histopathological and biochemical analyses. BLC-treated rats showed marked histopathological changes in the lungs. In these rats, thickening of interalveolar septa due to macrophage and lymphocyte infiltration, as well as fibroblast proliferation, were observed. Histopathological changes were less severe in the BLC+HP group compared with the BLC group. HP treatment led to a decrease in lipid peroxidation and an increase in antioxidant status compared with the BLC group. Also micro-CT showed a significant positive correlation with histopathological and biochemical results. To the best of our knowledge, this is the first study to evaluate the beneficial effects of HP against pulmonary fibrosis using histopathological, biochemical, and micro-CT analyses and HP successfully minimized the severity of BLC-induced lung injury, which was used as a model for IPF.Öğe Endovascular treatment of ruptured anterior circulation aneurysms within 24 hours: Clinical and angiographic results(2020) Kolu, Mehmet; Cigdem, Gulyara; Dere, Osman; Kaya, Veysel; Yildirim, Ismail Okan; Sarac, KayaAim: In this study, angiographic and clinical results after endovascular treatment were evaluated in patients with a ruptured brain aneurysm.Materials and Methods: A total of 32 patients, who admitted to the hospital between May 2018 and January 2020 due to aneurysmal subarachnoid hemorrhage (SAH), were included in the study. Cranial digital subtraction angiography (DSA) imaging was performed within the first 24 hours to patients with SAH detected on computed tomography and endovascular embolization was performed in 32 patients, who were considered as suitable for endovascular treatment. The pretreatment clinical scorings of the patients were evaluated according to the Hunt-Hess scale. Aneurysm occlusion was performed according to the Raymond-Ray classification. The patients were evaluated with the clinical outcome modified ranking scale (mRS) during their follow-up periods.Results: The endovascular treatment was successfully performed in all patients. In the first angiograms for control purposes after embolization, it was seen that the aneurysms were completely closed (RR1) in 81.25%, partial neck remained (RR2) in 12.5%, and the aneurysms were closed incompletely (RR3) in 6.25% of the patients. Intraprocedural complications developed in five patients (15.6%). There was an aneurysmal rupture in 1 patient (3.1%) and thromboembolic complications in 4 patients (12.5%). The procedure-related morbidity and mortality rates were 9.3% and 3.1%, respectively. No patients had postprocedural hemorrhagic complications. In the 3rd month, mRS was 0 in 21 (65.6%) patients, 1 (3.1%) in 1 patient, and 2 (6.25%) in 2 patients. A total of 11 (34.3%) patients died. A second procedure was performed in 2 (6.25%) of the patients who were followed because there was an RR3 residue.Conclusion: The endovascular embolization process can be applied in the treatment of intracranial aneurysms causing subarachnoid hemorrhage, and it is a safe and effective treatment method.Öğe Evaluation of Prostatic Artery Embolization Efficiency in Benign Prostatic Hyperplasia Patients with High Comorbidity(Galenos Yayincilik, 2018) Yildirim, Ismail Okan; Duman, Enes; Firat, Ali; Celik, Huseyin; Sarac, KayaObjective: The purpose of this study was to evaluate efficacy outcomes following prostate artery embolization (PAE) for the treatment of benign prostatic hyperplasia (BPH) patients with high comorbidity. Materials and Methods: This retrospective study included 22 patients treated with PAE from May 2015 to June 2017. Patients with Charlson comorbidity index >= 2, International Prostate Symptom Score (IPSS) >12, prostate specific antigen (PSA) levels <4 ng/mL or between 4 and 10 ng/mL with negative prostate biopsy and total prostate volume (TPV) >90 cm(3) were included. Total PSA, maximum flow rate (Q(max)), TPV, IPSS, post-voiding residual (PVR) values were recorded in all patients in the urology clinic before PAE and at 3 and 6 months after PAE. Results: The average patient age was 73.86 +/- 6.25 years and operative time was 80 minutes (range, 60-120 min). Pre-PAE and 6-month post-PAE values were: IPSS: 25.18 +/- 6.75 an d 11.27 +/- 3.29 (p<0.05), Q(max): 8.31 +/- 3.12 and 17.22 +/- 3.23 (p<0.05), PVR: 87.9 +/- 19.25 and 25.86 +/- 7.72 (p<0.05), TPV: 134.45 +/- 57.56 and 86 +/- 15.4 (p<0.05), and PSA: 3.89 +/- 1.26 and 2.11 +/- 1.06 (p<0.05). Embolization was performed unilaterally due to atherosclerosis and strictures in the internal iliac artery branches in 2 patients. After the procedure, 2 patients experienced transient hematuria which did not require bladder irrigation, 1 patient had acute urinary retention due to dysuria, and 1 patient had transient hematospermia. Conclusion: PAE may be an alternative treatment method in BPH patients with high comorbidity.Öğe Evaluation of prostatic artery embolization efficiency in benign prostatic hyperplasia patients withhigh comorbidity(Galenos yayıncılık, erkan mor, molla guranı cad 21-1, fındıkzade, ıstanbul 34093, turkey, 2018) Yildirim, Ismail Okan; Duman, Enes; Firat, Ali; Celik, Huseyin; Sarac, KayaObjective: The purpose of this study was to evaluate efficacy outcomes following prostate artery embolization (PAE) for the treatment of benign prostatic hyperplasia (BPH) patients with high comorbidity.

In this study, we present our two-year experience with percutaneous treatment for non-vascular complications following renal transplantation. PATIENTS AND METHODS: A total of 30 patients who underwent percutaneous radiological treatment between March 2014 and July 2016 were included in the study. RESULTS: Following renal transplantation, a total of 36 percutaneous radiological procedures which includes hydronephrosis secondary to ureteral stricture (n. 15), clinical symptom producing lymphocele due to pressure (14) and creatinine elevated nondilated grafts (n. 7) after excluding other reasons of creatinine elevation, were performed. Six patients received percutaneous treatment for both ureteral stricture and lymphocele. The patients underwent balloon dilatation and double-J ureteral stent due to ureteral stricture. The mean pre- and post-procedural creatinine levels were 4.36 +/- 2.84mg/dL and 2.17 +/- 1.24 mg/dL respectively (p=0.004), indicating a significant difference. For lymphocele treatment, sclerosing agents were injected and lymphatic leakage areas were injected with percutaneous glue. The mean pre- and post-procedural creatinine values were 2.97 +/- 1.78 mg/dL and 1.75 +/- 1.18 respectively (p=0.002), indicating a significant difference. Nephrostomy catheters were placed for patients with elevated creatinine levels and non-dilated collecting system. The mean pre- and post- nephrostomy creatinine levels were 3.55 +/- 2.36 mg/dL and 2.57 +/- 1.82 mg/dL respectively (p>0.05), indicating no statistically significant difference. CONCLUSION: The results of our study suggest that percutaneous treatment is an effective method for the treatment of non-vascular complications following renal transplantation, and, therefore, should be the first option for the preservation of graft functions.Öğe Multi-parameter-based radiological diagnosis of Chiari Malformation using Machine Learning Technology(Wiley-Hindawi, 2021) Tetik, Bora; Dogan, Gulec Mert; Pasahan, Ramazan; Durak, Mehmet Akif; Guldogan, Emek; Sarac, Kaya; Onal, CagatayBackground The known primary radiological diagnosis of Chiari Malformation-I (CM-I) is based on the degree of tonsillar herniation (TH) below the Foramen Magnum (FM). However, recent data also shows the association of such malformation with smaller posterior cranial fossa (PCF) volume and the anatomical issues regarding the Odontoid. This study presents the achieved result regarding some detected potential radiological findings that may aid CM-I diagnosis using several machine learning (ML) algorithms. Materials and Methods Midsagittal T1-weighted MR images were collected in 241 adult patients diagnosed with CM, eleven morphometric measures of the posterior cerebral fossa were performed. Patients whose imaging was performed in the same centre and on the same device were included in the study. By matching age and gender, radiological exams of 100 clinically/radiologically proven symptomatic CM-I cases and 100 healthy controls were assessed. Eleven morphometric measures of the posterior cerebral fossa were examined using 5 designed ML algorithms. Results The mean age of patients was 29.92 +/- 15.03 years. The primary presenting symptoms were headaches (62%). Syringomyelia and retrocurved-odontoid were detected in 34% and 8% of patients, respectively. All of the morphometric measures were significantly different between the groups, except for the distance from the dens axis to the posterior margin of FM. The Radom Forest model is found to have the best 1.0 (14 of 14) ratio of accuracy in regard to 14 different combinations of morphometric features. Conclusion Our study indicates the potential usefulness of ML-guided PCF measurements, other than TH, that may be used to predict and diagnose CM-I accurately. Combining two or three preferable osseous structure-based measurements may increase the accuracy of radiological diagnosis of CM-I.Öğe A novel technique in the treatment of lymphoceles after renal transplantation: c-arm cone beamct-guided percutaneous embolization of lymphatic leakage after lymphangiography(Lıppıncott wıllıams & wılkıns, two commerce sq, 2001 market st, phıladelphıa, pa 19103 usa, 2018) Yildirim, Ismail Okan; Piskin, Turgut; Duman, Enes; Firat, Ali; Dogan, Murat; Taskapan, Huelya; Sahin, Idris; Sarac, KayaBackground We aimed to evaluate the efficacy of percutaneous embolization after lymphangiography using C-arm cone-beam computed tomography (CBCT) performed at the site of lymphatic leakage in patients with postrenal transplant lymphocele. Methods Between July 2014 and August 2017, 13 patients not responding to percutaneous ethanol sclerotherapy and conservative treatment for recurrent lymphocele after renal transplant were included. The mean age of the patients was 56.38 9.91 (range, 36-70) years, and it comprised 9 men and 4 women. All patients underwent intranodal lymphangiography. C-arm CBCT-guided percutaneous embolization was performed in patients with confirmed lymphatic leakage. Patients who had no lymphatic leakage underwent drainage with fibrin glue injection. Results Lymphatic leakage was observed in 9 patients after lymphangiography, and they underwent CBCT-guided percutaneous N-butyl-2-cyanoacrylate embolization. The volume of lymphatic drainage reduced to less than 10 mL in 8 patients. One patient who was not responding to embolization was treated surgically, after percutaneous drainage and fibrin glue injection. Lymphatic leakage was not observed in 4 patients after lymphangiography. Of these, 3 patients showed a reduction in the amount of lymphatic drainage after lymphangiography. All 4 patients underwent percutaneous drainage and fibrin glue injection. One patient did not respond to the treatment and was treated surgically. Prelymphangiography and postlymphangiography and embolization, the volume of lymphatic drainage was 113.07 +/- 21.75 mL, and 53.84 +/- 30.96 mL, respectively, and statistically significant decrease was detected (P < 0.005). Conclusions Lymphangiography and CBCT-guided percutaneous embolization procedures might be an effective treatment method for patients with lymphocele refractory to treatment.Öğe Single-Voxel Magnetic Resonance Spectroscopy of Brain Tissue Adjacent to Arachnoid Cysts of Epileptic Patients(Lippincott Williams & Wilkins, 2008) Ozisik, Handan Isin; Sarac, Kaya; Ozcan, CemalIntracranial arachnoid cysts (ACs) are usually asymptomatic, benign developmental anomalies. The most frequent clinical manifestations are cranial expansion, hydrocephaly, headache, epileptic seizures, psychomotor retardation, and aphasia. It is unknown whether there is a correlation between intracranial AC and epileptic seizures without obvious intracranial pressure signs. In vivo magnetic resonance spectroscopy is a technique used for the noninvasive investigation of the various metabolites of cerebral biochemical reactions. Magnetic resonance spectroscopy is also being used increasingly commonly in epileptogenic situations as a noninvasive technique. The purpose of this study was to evaluate the proton magnetic resonance spectroscopic pattern of the contents of tissue adjacent to AC and to determine whether there are any characteristic spectral patterns that may be helpful in evaluating whether these lesions are epileptogenic foci. In conclusion, although the number of cases was limited, this finding may be seen as indicating that there is no association between AC and epilepsy.Öğe Sudden-onset paraplegia during pregnancy caused by haemorrhage in a spinal cord haemangioblastoma: A case report(Pakistan Medical Assoc, 2016) Gormeli, Cemile Ayse; Sarac, Kaya; Ozdemir, Zeynep Maras; Gormeli, Gokay; Kahraman, Aysegul Sagir; Kahraman, Bayram; Oztanir, Mustafa NamikSpinal cord haemangioblastomas are rare central nervous systems tumours, and haemorrhage. It is an uncommon occurance. We report a 28-year-old pregnant patient who presented with paraplegia due to acute haemorrhage of a spinal haemangioblastoma. Magnetic resonance imaging showed extensive syrinx cavities, an intramedullary lesion at the T4-T5 spinal cord level e, and a subarachnoid haemorrhage. Digital subtraction angiography showed the feeding artery and dilated tortuous draining vein within the dural sac. The lesion was deemed a haemangioblastoma. The histopathological examination confirmed the diagnosis. Postoperatively, the paraplegia improved and the patient was able to walk within 2 weeks. Imaging is important for early diagnosis to prevent patients persistent neurological deficits.Öğe Superior Ophthalmic Vein Thrombosis Developed after Orbital Cellulitis(Taylor & Francis Inc, 2013) Cumurcu, Tongabay; Demirel, Soner; Keser, Sinem; Bulut, Taner; Cavdar, Mufide; Dogan, Metin; Sarac, KayaA 65-year-old female patient presented with eye pain, swelling and blurred vision in the left eye. Routine biochemistry and microbiological analyzes were conducted. Orbital tomography (CT), magnetic resonance imaging (MRI) findings, and cerebral angiography were performed. Orbital cellulitis due to a complication of ethmoidal sinusitis was diagnosed with thrombosis of the SOV in the patient. Systemic broad-spectrum antibiotic and anticoagulant therapy was started on the patient. The patient's symptoms were recorded at the end of two weeks of the treatment.Öğe Typhlitis in rectum(Wiley, 2010) Ozgen, Unsal; Uzum, Isa; Mizrak, Buelent; Sarac, Kaya[Abstract Not Available]Öğe Ultrasonography and fluoroscopy guided implantable chest ports in pediatric oncology patients: single center experience(Allied Acad, 2017) Yildirim, Ismail Okan; Sarac, KayaObjective: To evaluate the long term outcomes of implantable chest ports in pediatric oncology patients. Material and methods: The study includes chest port insertion procedures performed in a total of 68 pediatric oncology patients (31 girls and 37 boys) at Department of Interventional Radiology between October 2014 and October 2016. Mean age of the patients was 6.28 years (range 6 months-16 years). All procedures were performed under ultrasonography and fluoroscopy guidance. All data were analyzed restrospectively. Results: Technical success of all procedures was 100%. Duration of use is mean 199 days for chest port catheter (range 1-302 day). Perioperative complications developed in 4 patients (n=2 jugular vein and port pocket site hemorrhage, n=2 catheter malposition) and long-term complications developed in 9 (n=2 catheter malposition, n=1 insertion site infection, n=3 catheter-related blood stream infection, n=3 skin dehiscense). Premature catheter removal occurred in 8 patients. Conclusion: Insertion of ultrasonography and fluoroscopy-guided implantable port devices results in high technical success and low complication rates. This condition suggests that interventional radiologists would come in the foreground in this field.Öğe Use of angiographic embolization in trauma-induced pediatric abdominal solid organ injuries(Turkish Assoc Trauma Emergency Surgery, 2019) Gurunluoglu, Kubilay; Ceran, Canan; Yildirim, Ismail Okan; Kutlu, Ramazan; Sarac, Kaya; Yildiz, Turan; Bayrakci, ErcanBACKGROUND: Knowledge of the utility of angiographic embolization (AE) in pediatric cases of blunt abdominal solid organ trauma injuries is limited. The current study is an examination of AE as an effective and reliable method to control bleeding in patients with persistent bleeding due to blunt trauma-induced abdominal solid organ injury. METHODS: This was a retrospective examination of patients < 17 years of age who had experienced blunt abdominal solid organ injury and who presented at a single institution within 4 years. A statistical analysis of the data was performed. RESULTS: The mean length of intensive care unit stay was 4 days for those who underwent embolization (n= 11), and the mean length of hospital stay was 12 days. The average pre-AE blood loss, as measured by the decrease in hematocrit (%) from admission to embolization, was -7.33 +/- 5.3% (p< 0.001). The average post-AE blood loss, as measured by the change in hematocrit 72 hours post AE, was 2 +/- 0.97% (p> 0.05). All of the patients were discharged with a full recovery. CONCLUSION: AE was a safe and effective method to control solid organ hemorrhage in pediatric patients with blunt abdominal injuries.
