Öğe Abdominal aort anevrizması olan üç olgunun spiral bt anjiografisi(İnönü Üniversitesi Tıp Fakültesi Dergisi, 1997) Kutlu, Ramazan; Saraç, Kaya; Baysal, Tamer; Türköz, Rıza; Gülcüler, Metin; Gülcan, ÖnerAbdominal aort anevrizması operasyonlarının planlanmasında, cerrahi öncesi komşu vasküler yapılarla ilişkisinin belirlenmesi önemlidir. Bu yazıda abdominal aort anevrizması tespit edilen üç olgunun, cerrahi öncesi spiral bilgisayarlı tomografik anjiografi (SBTA) ile elde edilen görüntülerini ve SBTA’nın bu tip olgulardaki değerini irdeledik. SBTA'nın abdominal aort anevrizmalarında, anevrizmaların teşhisinden öte lokalizasyon ve diğer damarlarla ilişkisini saptamada oldukça önemli olduğunu düşünmekteyiz.Öğe Acute subdural hematomas caused by ruptured aneurysms: Experience from a single turkish center(Turkish Neurosurgery, 2009) Koçak, Ayhan; Ateş, Özkan; Durak, Mehmet Akif; Alkan, Alpay; Çaylı, Süleyman; Saraç, KayaÖz: AMAÇ: Bir anevrizma ruptürü tipik olarak tomografide subaraknoid kanama ile ortaya çıkmasına rağmen kendiliğinden (travmasız) subdural kanama ile beraber görülebilir. Bu makalenin amacı, bu hayatı tehdit eden durumun klinik ve radyolojik özellikleriyle birlikte tanı ve tedavisindeki potansiyel tehlikeleri tartışmaktır. YÖNTEM ve GEREÇ: İnönü Üniversitesi Nöroşirürji Anabilimdalı (Turgut Özal Tıp Merkezi) 1999’dan bu yana intrakraniyal anevrizma tanısı ile tedavi edilen hastaların kayıtlarını prospektif olarak tutmaktadır. Bu veri tabanını kullanarak, tomografisinde akut subdural kanama ile gelen ruptüre anevrizma hastalarını tespit ettik. BULGULAR: Ocak 2000-Ocak 2009 tarihleri arasında radyolojik olarak dökümante edilmiş 687 hasta başvurdu. Bunların 11 (on bir) tanesinde akut travmatik olmayan subdural kanama mevcuttu. Akut subdural kanama-anevrizma rüptürü birlikteliği serimizde % 1,6 idi. SONUÇ: Subaraknoid kanamanın varlığı veya yokluğunda bile, tomografide görülen akut travmatik olmayan subdural kanama anevrizma ruptürü ile ilgili acil çalışmaları düşündürmelidir. CT anjiyografinin DSA’ya göre avantajları vardır ve akut olan bir travmatik olmayan subdural kanama olgularının tedavi planlaması, triyajı ve tanısında makul bir alternatif modalitedir.Öğe Advantages of early intervention with arterial embolization for intra-abdominal solid organ injuries in children(2019) Demircan, Mehmet; Gürünlüoğlu, Kubilay; Gözükara Bağ, Harika; Sığırcı, Ahmet; Saraç, Kaya; Kutlu, Ramazan; Yıldırım, İsmail OkanAbstract: PURPOSE Active bleeding due to abdominal trauma is an important cause of mortality in childhood. The aim of this study is to demonstrate the advantages of early percutaneous transcatheter arterial embolization (PTAE) procedures in children with intra-abdominal hemorrhage due to blunt trauma. METHODS Children with blunt abdominal trauma were retrospectively included. Two groups were identified for inclusion: patients with early embolization (EE group, n=10) and patients with late embolization (LE group, n=11). Both groups were investigated retrospectively and statistically analyzed with regard to lengths of stay in the intensive care unit and in the hospital, first enteral feeding after trauma, blood transfusion requirements, and cost. RESULTS The duration of stay in the intensive care unit was greater in the LE group than in the EE group (4 days vs. 2 days, respectively). The duration of hospital stay was greater in the LE group than in the EE group (14 days vs. 6 days, respectively). Blood transfusion requirements (15 cc/kg of RBC packs) were greater in the LE group than in the EE group (3 vs. 1, respectively). The total hospital cost was higher in the LE group than in the EE group (4502 USD vs. 1371.5 USD, respectively). The time before starting enteral feeding after first admission was higher in the LE group than in the EE group (4 days vs. 1 day, respectively). CONCLUSION Early embolization with PTAE results in shorter intensive care and hospitalization stays, earlier enteral feeding, and lower hospital costs for pediatric patients with intra-abdominal hemorrhage due to blunt trauma.Öğe Arteriyovenöz fistüllü hemodiyaliz hastasının yaşam kalitesinde multidisipliner yaklaşımın önemi(Türk Göğüs Kalp Damar Cerrahisi Dergisi, 2006) Alat, İlker; Akpınar, Mehmet Beşir; Bahçeci, Funda; Taşkapan, Hülya; Kutlu, Ramazan; Saraç, Kaya; Battaloğlu, Bektaş; Nisanoğlu, VedatÖz: Arteriyovenöz fistüllerin, uzun dönem başarısını etkileyen faktörler beş olguda hemodiyaliz amaçlı olarak incelendi. Arteriyovenöz fistüllerin oluşturulmasında kalp ve damar cerrahı için "dolaşım yeterliliğinin tespiti" önemlidir. Hastanın ameliyata girmeden önce geçirdiği aşamalar da ameliyatın stratejisini değiştirecektir. Ameliyattan sonraki dönemde fistülün başarısına etki eden en önemli faktör ise hemodiyaliz personelinin eğitimidir. Kalp ve damar cerrahının fistülde başarı elde edebilmesinde en büyük yardımcıları aynı zamanda invaziv radyologlardır. Arteriyovenöz fistül cerrahisinin hastaya bir hayat sunduğu unutulmamalıdır. Bu konuda başarılı olmada multidisipliner yaklaşımın önemi vurgulandı.Öğe Bare stent implantation in iatrogenic dissecting pseudoaneurysm of the superior mesenteric artery(Cardiovasc Intervent Radiol, 2007) Kutlu, Ramazan; Ara, Cengiz; Saraç, KayaLatrogenic arterial dissection leading to the development of dissecting pseudoaneurysms of the superior mesenteric artery (SMA) is a rare complication of angiography. Surgical and endovascular treatment options exist for this important condition. We report a case of bare stent implantation in dissecting pseudoaneurysm of the SMA that developed after angiography in a patient with acute mesenteric ischemia. Although it is rarely published, iatrogenic arterial dissection causing pseudoaneurysm can occur after diagnostic and interventional angiography. Bare stent implantation in dissecting pseudoaneurysm of the SMA could be an advantageous endovascular treatment option in selected cases due its to potential preservation of important side branches of the SMA.Öğe Bipolar affektif bozukluklu hastalarda lityum ve olanzapin tedavisinin etkileri: Beyin MRSs bulguları(Anadolu Psikiyatri Dergisi, 2004) Cumurcu, Elbozan Birgül; Karlıdağ, Rıfat; Saraç, Kaya; Ünal, Süheyla; Özcan, CemalÖz: Amaç: Bu çalışmada, remisyon dönemindeki bipolar affektif bozukluklu hastalarda lityum ve olanzapin tedavisi ile beyin manyetik rezonans spektroskopi (MR spektroskopi) bulgularındaki değişiklikler ve bunun nöroprotektivite ile ilişkisi araştırıldı. Yöntem: Psikiyatri polikliniğinde izlenen, 3 yıl boyunca manik ve depresif bir atak geçirmemiş ve son 6 aydır sadece lityum tedavisi almakta olan 10 bipolar affektif bozukluk hastası çalışmaya alındı. Hastalar lityum kullandıkları dönemde, lityumun kesilmesini takiben 14. günde ve olanzapin başlandıktan sonraki 4. haftanın sonunda olmak üzere 3 kez değerlendirildi. Her bir değerlendirme klinik psikiyatrik görüşme, Hamilton depresyon derecelendirme Ölçeği (HDÛÖ) ve Bech-Rafaelson Mani Ölçeği (BRMÖ) uygulaması ve MR spektroskopi çekimini kapsadı. MR spektroskopide, sağ prefrontal korteks ve sol hipokampüs bölgelerinde kantitatif olarak N-asetil aspartat (NAA), kolin (Cho) pikleri ölçüldü ve bunların kreatine (Cr) pikine oranlarına bakıldı. Her 3 çekimdeki değerler birbiriyle karşılaştırıldı. Bulgular: Çalışmaya 5 kadın ve 5 erkek hasta katıldı. Ortalama yaşları 33.10+9.17yıl idi. Lityum alırken, ilaçsız dönemde ve.olanzapin alırken çekilen MR spektroskopilerinde NAA/Cr ve Cho/Cr oranları arasında istatistiksel açıdan anlamlı farklılık saptanmadı. Sonuç: Remisyonda bipolar affektif bozukluklu hastalarda lityum ve olanzapin tedavisiyle beyin NAA ve Cho düzeylerinin değişmediğini düşündürmektedir.Öğe Brain metabolite changes on proton magnetic resonance spectroscopy in children with poorly controlled type 1 diabetes mellitus(Neuroradiology, 2005) Saraç, Kaya; Akıncı, Ayşehan; Alkan, Alpay; Aslan, Mehmet; Baysal, Tamer; Özcan, AbdulcemalAbstract The metabolite changes in the brains of children with poorly controlled type 1 diabetes mellitus (DM) were investigated by proton magnetic resonance spectroscopy (MRS). A total of 30 subjects and 14 age-matched healthy volunteers underwent single-voxel MRS (TE: 136). The duration of disease, medication, presence of hypoglycaemia episodes and the level of haemoglobin A1C (HbA1C) in the patients were noted. Voxels were placed in the pons, left basal ganglion (LBG) and left posterior parietal white matter (PPWM). N-acetylaspartate (NAA)/creatinine (Cr) and choline (Cho)/Cr ratios were calculated. The average HbA1c level was 11.9±3.4 (8.2–19.4). The average number of keto-acidosis episodes was 1.9±2.2 (0–9) and the average number of daily insulin injections was 2.8±0.97 (2–4). MRS revealed lower NAA/Cr and Cho/Cr ratios in the pons and lower NAA/Cr ratio in the PPWM of patients with DM than in control subjects. No significant correlation was observed between the number of hypoglycaemia episodes and metabolite ratios. Metabolic abnormalities have been observed by MRS in the brain of poorly controlled type 1 DM children. These metabolic changes, in particular in the pons region, include a decrease in NAA, indicating neuronal loss or functional impairment, and likely explanations for a decrease in Cho may be dynamic changes in membrane lipids and/or decreased membrane turnover.Öğe Brain metabolite changes on proton magnetic resonance spectroscopy in children with poorly controlled type1 diabetes mellitus(NEURORADIOLOGY, 2005) Saraç, Kaya; Akıncı, Ayşehan; Alkan, Alpay; Aslan, Mehmet; Baysal, Tamer; Özcan, AbdulcemalThe metabolite changes in the brains of children with poorly controlled type 1 diabetes mellitus (DM) were investigated by proton magnetic resonance spectroscopy (MRS).

Material and methods: A total of 49 children with history of RF and 31 healthy controls were included into the study. All patients and control group underwent a detailed neuropsychiatric evaluation. Children with the history of RF were classified into three groups as; group 1: with history of RF without neuropsychiatric complications (NCRF), group 2: only with history of SC (HSC), group 3: with HSC and OCTD (OCTD). After MR imaging, single voxel MR spectroscopy was performed in all subjects. Voxels (15 × 15 × 15 mm) were placed in basal ganglia. N-acetyl aspartate (NAA)/creatin (Cr), and choline (Cho)/Cr ratios were calculated. Results: OCTD were detected in 13 children with HSC. NAA/Cr ratio was found to be decreased in these children when compared with NCRF (n:29), HSC without OCTD (n:7) and control groups (n:31). No significant difference was found in metabolite ratios of children with HSC without OCTD when compared with NCRF and control groups. There were no significant differences in Cho/Cr ratio between patient and control groups. Conclusion: Although MR imaging findings was normal, MR spectroscopy findings (decreased NAA/Cr ratio) in our study support the neuronal loss in basal ganglia of children with OCTD and could indicate the development of permanent damage.Öğe A case of migrating intracranial bullet(Appl Radiol, 2004) Kutlu, Ramazan; Koçak, Ayhan; Çaylı, Süleyman; Alkan, Alpay; Sığırcı, Ahmet; Saraç, KayaÖğe The cisternal segment of the abducens nerve in man three dimensional MR imaging(Eur J Radiol, 2004) Alkan, Alpay; Sığırcı, Ahmet; Özveren, M. Faik; Kutlu, Ramazan; Altınok, Tayfun; Önal, Çağatay; Saraç, KayaPurpose: The goal of this study was to identify the abducens nerve in its cisternal segment by using three-dimensional turbo spin echo T2-weighted image (3DT2-TSE). The abducens nerve may arise from the medullopontine sulcus by one singular or two separated rootlets. Material and methods: We studied 285 patients (150 males, 135 females, age range: 9–72 years, mean age: 33.3 ± 14.4) referred to MR imaging of the inner ear, internal auditory canal and brainstem. All 3D T2-TSE studies were performed with a 1.5 T MR system. Imaging parameters used for 3DT2-TSE sequence were TR:4000, TE:150, and 0.70 mm slice thickness. A field of view of 160 mm and 256×256 matrix were used. The double rootlets of the abducens nerve and contralateral abducens nerves and their relationships with anatomical structures were searched in the subarachnoid space. Results: We identified 540 of 570 abducens nerves (94.7%) in its complete cisternal course with certainty. Seventy-two cases (25.2%) in the present study had double rootlets of the abducens nerve. In 59 of these cases (34 on the right side and 25 on the left) presented with unilateral double rootlets of the abducens. Thirteen cases presented with bilateral double rootlets of the abducens (4.5%). Conclusion: An abducens nerve arising by two separate rootlets is not a rare variation. The detection of this anatomical variation by preoperative MR imaging is important to avoid partial damage of the nerve during surgical procedures. The 3DT2-TSE as a noninvasive technique makes it possible to obtain extremely high-quality images of microstructures as cranial nerves and surrounding vessels in the cerebellopontine cistern. Therefore, preoperative MR imaging should be performed to detect anatomical variations of abducens nerve and to reduce the chance of operative injuries.Öğe Complex partial seizure-induced transient magnetic resonance change in SLE as first manifestation(1998) Bölük, Ayhan; Saraç, Kaya; Kalı, Sinem; Özcan, CemalBu yazıda parsiyel status epileptikus (SE) ile ilişkili geçici manyetik rezonans görüntüleme (MRG) anormallikleri olan SLE (Sistemik Lupus Eritrematosis)'li bir kadın olgusunu sunmaktayız. İlk klinik belirtisi iktal EEG'de temporal maksimum ile beraber kompleks parsiyel nöbetti. Sol temporal fobun intensitesi 72 ağırlıklı MR görüntülerinde artmıştı, fakat iki ay sonraki nörogörüntüleme normaldi. Serebral ödemle uyumlu foka/ serebral MRG anormallikleri parsiyel status epileptikus yüzünden meydana çıkmış olabilir. Nöropsikiyatrik SLE'si olan, özellikle klinik ve EEG ile şüpheli nöbetleri olan, hastada değişiklikler MRG ile korrele edilmelidir.Öğe Delayed myelination in a rhizomelic chondrodysplasia punctata case MR spectroscopy findings(Magn Reson Imaging, 2003) Alkan, Alpay; Kutlu, Ramazan; Yakıncı, Mehmet Cengiz; Sığırcı, Ahmet; Aslan, Mehmet; Saraç, KayaRhizomelic chondrodysplasia punctata is a member of genetic peroxisomal disorders. Delayed myelination, which is probably related to the inadequacy of plasmalogens biosynthesis, is an important feature of this disorder. Direct assessment of neuropathologic aspects of RCDP syndrome such as neuronal degeneration and delayed myelination is possible with MR spectroscopy. In this report, MR spectroscopy findings (decreased Cho/Cr and increased Ins-Gly/Cr ratios and increased levels of mobile lipids) of a rhizomelic chondrodysplasia punctata case supporting delayed myelination are presented. This is the second report of MR spectroscopy examination of the specific brain metabolic changes associated with rhizomelic chondrodysplasia punctata. © 2003 Elsevier Science Inc.

The purpose of this study was to evaluate the Doppler sonographic blood-flow parameters and spectral patterns in the inferior mesenteric artery (IMA) and superior mesenteric artery (SMA) in patients with active and inactive (remission-phase) ulcerative colitis (UC). Methods. The IMAs and SMAs of 25 patients with active-phase UC (group 1), 19 patients with remissionphase UC (group 2), and 22 healthy, asymptomatic subjects (control group) were evaluated by duplex Doppler sonography. The 25 patients in group 1 were categorized into 2 subgroups on the basis of the extent of disease as determined by double-contrast barium enema x-ray study and colonoscopy. The first subgroup (group 1a) consisted of 11 patients with active involvement of the left colon from the rectum to the splenic flexure. The second subgroup (group 1b) consisted of 14 patients with active involvement of the entire colon. The peak systolic velocity (PSV), enddiastolic velocity (EDV), mean velocity (Vmean), resistance index (RI), and pulsatility index (PI) were determined from the Doppler spectral analysis. The inner diameter and cross-sectional area of the IMA and SMA were measured, and the blood-flow volume was calculated. The results were compared between the patient groups and control subjects. Results. In the IMA, the mean blood-flow volume, mean PSV, mean EDV, and Vmean were significantly higher, the mean PI was significantly lower, and the mean diameter and the mean cross-sectional area were significantly larger in group 1 than in group 2 or in the control group (p < 0.001). The mean PSV and the Vmean of the IMA were significantly higher in group 1a than in group 1b (p < 0.05). The mean blood-flow parameters in the SMA were not significantly different between groups 1 and 2 or between either group 1 or group 2 and the control subjects. The mean EDV in the SMA was significantly higher and the mean PI and the mean RI were significantly lower in group 1b than in group 1a (p < 0.01). Conclusions. Duplex Doppler sonography of the IMA and SMA can be used to evaluate inflammatory disease of the large bowel, to assess disease extent, and to document response to therapy.Öğe Doppler waveforms and blood flow parameters of the superior and inferior mesenteric arteries in patients having behçet disease with and without gastrointestinal symptoms(J Ultrasound Med, 2003) Sığırcı, Ahmet; Şenol, Mustafa; Aydın, Erdinç; Kutlu, Ramazan; Alkan, Alpay; Altınok, M. Tayfun; Yoloğlu, Saim; Baysal, Tamer; Saraç, KayaObjective. To evaluate hemodynamic changes in mesenteric arteries in patients with Behçet disease with and without gastrointestinal symptoms. Methods. Doppler sonography of mesenteric arteries was performed in 25 symptomatic and 15 asymptomatic patients having Behçet disease and in 25 healthy control subjects. The peak systolic, minimal, and mean velocities, resistive and pulsatility indexes, inner diameter, cross-sectional area, and blood flow volume of mesenteric arteries were evaluated. The results were compared between patient groups and controls. Results. The mesenteric artery flow was significantly greater in patients in the symptomatic group than in those in the asymptomatic group or in controls. In the superior mesenteric artery, mean velocity and mean blood flow volume (0.35 ± 0.18 m/s and 711 ± 404 mL/min, respectively; P < .0001) in the symptomatic group were significantly higher than in the asymptomatic group (0.16 ± 0.07 m/s and 305 ± 168 mL/min, respectively) or in controls (0.15 ± 0.07 m/s and 290 ± 123 mL/min, respectively). The mean peak systolic velocity (1.23 ± 0.47 m/s; P < .005) in the symptomatic group was significantly higher than in controls (0.93 ± 0.23 m/s). In the inferior mesenteric artery, mean velocity and mean blood flow volume (0.25 ± 0.10 m/s and 139 ± 79 mL/min) in the symptomatic group were significantly higher than in the asymptomatic group (0.16 ± 0.07 m/s; P < .006; and 78 ± 26 mL/min; P < .007) or in controls (0.17 ± 0.07 m/s; P < .003; 83 ± 48 mL/min; P < .004). Conclusions. In this study, symptomatic patients with gastrointestinal Behçet disease were associated with a significant increase in mesenteric artery flow that could be evaluated easily on spectral patterns of arteries during Doppler sonography. The Doppler sonographic findings also revealed that intestinal involvement in patients with Behçet disease without gastrointestinal symptoms is not significantly different from that of healthy controls.Öğe Early and late state subacute sclerosing panencephalitis chemical shift imaging and single voxel MR spectroscopy(AJNR, 2003) Alkan, Alpay; Saraç, Kaya; Kutlu, Ramazan; Yakıncı, Mehmet Cengiz; Sığırcı, Ahmet; Aslan, Mehmet; Baysal, TamerSubacute sclerosing panencephalitis (SSPE) is a rare, progressive, inflammatory neurodegenerative disease. Our aim was to determine the metabolic abnormalities of brain in early- and late-stage SSPE by using MR spectroscopy and to assess areas of involvement in the early stages when MR imaging findings were normal. METHODS: Children with stage II (n 3) or III (n 3) SSPE and 10 healthy, age-matched children underwent MR imaging, multivoxel MR spectroscopy, and short-echo single-voxel MR spectroscopy (SVS). Areas of involvement in the brain were determined with chemical shift imaging. For SVS, 2 2 2-cm voxels were placed in the frontal subcortical white matter (FSWM) and parieto-occipital white matter (POWM). N-acetylaspartate (NAA)/creatine (Cr), choline (Cho)/Cr, myo-inositol (Ins)/Cr, and NAA/Cho ratios were calculated. RESULTS: Comparisons of NAA/Cr, Cho/Cr, Ins/Cr and NAA/Cho ratios between patients and control subjects showed significant differences in FSWM and POWM (P < .01). In patients with SSPE, NAA/Cr ratios in POWM were significantly less than those in FSWM (P < .01). NAA/Cr ratios in patients with stage II SSPE and those in the control group were not significantly different; this may reflect the absence of neuronal loss. Decreased NAA/Cr, increased Cho/Cr and Ins/Cr ratios, and increased lactate and lipid peaks were found in patients with stage III SSPE. CONCLUSION: MR spectroscopy showed findings suggestive of inflammation in stage II and findings of demyelination, gliosis, cellular necrosis, and anaerobic metabolism in stage III. MR spectroscopy could be a promising technique for early diagnosis and treatment planning in cases of SSPE.Öğe Early MRI findings in stab wound of the cervical spine two case reports(Neuroradiology, 2002) Alkan, Alpay; Baysal, Tamer; Saraç, Kaya; Sığırcı, Ahmet; Kutlu, RamazanÖğe Effects of testicular microlithiasis on Doppler parameters report of three cases(BMC Urol, 2002) Kutlu, Ramazan; Sığırcı, Ahmet; Baysal, Tamer; Alkan, Alpay; Saraç, KayaBackground: Testicular microlithiasis is a rare, usually asymptomatic, non-progressive disease of the testes associated with various genetic anomalies, infertility and testicular tumors. According to our literature search, there is no specific data about Doppler findings in this disease. Case presentation: Doppler findings of three cases of testicular microlithiasis during last two years in our institution are presented. Conclusions: Although our hypothesis was to find increased Doppler parameters due to intratesticular arterial compression, our findings suggest that there are no Doppler findings specific to testicular microlithiasis.Öğe Efficiency of mechanical thrombectomy in acute ischemic stroke patients(2020) Kolu, Mehmet; Yıldırım, İsmail Okan; Turan Kaya, Ahmet; Kamışlı, Suat; Kaplan, Yüksel; Durak, Mehmet Akif; Gürbüz, Şükrü; Saraç, KayaAbstract: The aim of this single-center study is to assess the outcomes in patients with acute ischemic stroke underwent endovascular mechanical thrombectomy. The data and outcome of patients who were admitted due to acute ischemic stroke caused by a large vessel occlusion in the anterior or posterior circulation and treated with endovascular stent retriever mechanical thrombectomy between 2014 and 2018 were retrospectively evaluated. Recanalization success was assessed based on Thrombolysis in Cerebral Infarction (TICI) scores, and the TICI grades 2b and 3 were considered as ‘successful’. Functional outcomes of the patients were assessed by modified Rankin Scale (mRS) at the 3rd month follow up and a score of ?2 points was considered as ‘good clinical outcome’. Successful recanalization was achieved in 34 patients (69%). At the 3rd month follow-up, 23 patients (46,9%) had mRS scores of ?2 points. The overall mortality rate at the 90th day was %30 (n=15). After endovascular thrombectomy, symptomatic intracranial hemorrhage was seen in 9 patients, groin hematoma due to vascular access in 5 patients, which did not require additional treatment, and pseudoaneurysm in 3 patients. Stent retriever mechanical thrombectomy is an effective and safe procedure in patients admitted due to acute ischemic stroke caused by large vessel occlusion.Öğe El yerleşimli periosteal kondroma: İki vaka(İnönü Üniversitesi Tıp Fakültesi Dergisi, 1996) Saraç, Kaya; Kaygusuz, Akif; Elmalı, NurzatPeriosteal chondromas are rare cases and also rarely seen in hand bones.
