Öğe Embolization with more diluted glue-lipiodol in patients with massive hemoptysis: single center experience results(Verduci Publisher, 2022) Kolu, M.; Kurtulus, S.; Dere, O.; Yurttutan, N.; Yildirim, I. O.OBJECTIVE: The aim of the study was to demonstrate the efficacy and safety of bronchial artery embolization (BAE) with more diluted N-butyl -2-cyanoacrylate (NBCA) in patients with massive hemoptysis. PATIENTS AND METHODS: In this retrospective study, there are 48 patients who underwent NBCA and BAE for massive hemoptysis between March 2018 and September 2021. Demographic data, technical and clinical results, immediate hemoptysis control, recurrent hemoptysis and complications were evaluated. RESULTS: The technical success rate and immediate hemoptysis control were achieved in 97.9% and 93.7%, respectively. The 3 patients who were exitus within the first 10 days were removed from the follow-up range. During the follow-up period (range, 5 months-42 months; median, 27.5 months), recurrent hemoptysis was found in 3 of the 45 patients (6.6 %). Since 1 patient refused and one patient died within the first 24 hours, repeated BAE procedures were performed in 4 patients. A total of 55 sessions of BAE with NBCA was performed to 48 patients. The underlying diseases causing hemoptysis were determined to be bronchiectasis (n=16), tuberculosis (n=8), neoplasm (n=7), aspergilloma (n=3), and arteriovenous malformation (n=2). In 4 patients, bronchiectasis and tuberculosis were present together and in 8 patients, the cause could not be specified. CONCLUSIONS: In conclusion, BAE with more diluted NBCA is a safe and effective embolization method. In addition, the use of more diluted NBCA reduces the recurrence rates in patients with hemoptysis.Öğe Endovascular Approach to Giant Splenic Artery Aneurysm after Liver Transplantation(Lippincott Williams & Wilkins, 2017) Akbulut, S.; Kutlu, R.; Kolu, M.; Karipkiz, Y.; Yilmaz, S.[Abstract Not Available]Öğe Evaluation of risk factors in pneumothorax development after computerized tomography-guided transthoracic biopsy and management of complications(Wolters Kluwer Medknow Publications, 2020) Kolu, M.; Yildirim, I. O.Aims: This study aims to discuss the relationship between complications and patient characteristics and lesion properties in the transthoracic fine needle aspiration biopsy (TTFNAB) procedures performed for lung lesions and the treatment applied in our clinic to eliminate these complications. Methods: In this retrospective study conducted from July 2014 to August 2017, the CT-guided TTFNAB was performed on 186 patients (145 males, 41 females) who were considered to have malignancies on their clinical evaluation, CT, and PET CT results. Results: After 186 CT-guided TTFNAB interventions, a total of 24 (12.9%) patients developed procedure-related pneumothorax. Of these patients, 7 had a limited and minimal pneumothorax and no treatment was required for them, while 17 had a large and increasing pneumothorax and manual air aspiration was performed with coaxial needle during the procedure. The number pleural transitions (OR 6.513; 95%, 2,529-16,771 P < 0.001), emphysematous lungs (OR 4.612; 95%, 1,852-11.487 P < 0.001), and the presence of a lesion unrelated to the pleura (OR 8.205; 95%, 3,162-21,291 P < 0.001) can form the basis for the development of a pneumothorax. Conclusion: The chances of developing pneumothorax after TTFNAB depend on number of pleural transition, emphysematous lungs, and non-pleural lesions. However, it is considered that procedures such as manual air aspiration and autologous blood patch may reduce the need for chest tube following the development of pneumothorax.Öğe Gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid enhanced magnetic resonance imaging-guided risk assessment in living donor liver transplant patients with postoperative complications: a pilot study(Verduci Publisher, 2021) Kolu, M.; Kahraman, A. S.; Akbulut, S.; Yildirim, I. O.OBJECTIVE: To evaluate whether gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) enhanced magnetic resonance imaging (MRI), the measurements of quantitative and qualitative parameters on hepatobiliary phase images can predict the risk of postoperative complications in patients underwent living donor liver transplantation (LDLT) PATIENTS AND METHODS: We obtained Gd-EOB-DTPA-enhanced 3 Tesla MRI before living donor hepatectomy in donors (donor group: n=30) and after LDLT in their recipients (recipient group; n=30). MRIs were evaluated in terms of quantitative and qualitative variables. Quantitative parameters included relative liver enhancement value, biliary signal intensity value, and muscle signal index value. Qualitative parameters included visual evaluation of the liver and biliary enhancement on hepatobiliary phase images. Patients were followed up for postoperative biliary and vascular complications and divided according to the presence and absence of complications. The relationship between MRI parameters and postoperative complications was statistically analyzed. RESULTS: The mean relative liver enhancement values, mean biliary signal values, and muscle signal index were significantly lower in recipients with postoperative complications than those in donors and recipients without complications (p < 0.001). Visual assessments of liver enhancement and biliary signal were also significantly different in recipients with postoperative complications than that in donors and recipients without complications (p < 0.001). CONCLUSIONS: Quantitative and qualitative MRI parameters obtained by Gd-EOB-DTPA-en- hanced MRI on hepatobiliary phase images may potentially become a reliable tool for the assessment of the risk for postoperative complications after LDLT.
