Öğe Computed tomographic perfusion imaging for the prediction of response transarterial radioembolization with Yttrium-90 glass microspheres of hepatocellular carcinoma (vol 25, pg 366, 2021)(Verduci Publisher, 2021) Kaplan, E.; Kutlu, R.; Erbay, M.

Otlu; Kaplan, S.[Abstract Not Available]Öğe Diagnostic value of penile color doppler ultrasonography in patients with veno-occlusive erectile dysfunction(Wolters Kluwer Medknow Publications, 2021) Soylu, A.; Sarier, M.; Kutlu, R.Background: The method used in the first assessment of patients with veno-occlusive erectile dysfunction (ED) is penile color doppler ultrasonography (PCDU). However, cavernosography performed following intracavernosal pharmacostimulation is accepted as a more precise method for showing venous leakage. Aims: The objectives of this study were to compare results obtained from patients undergoing PCDU, and those undergoing cavernosography, and to investigate the diagnostic value of PCDU in the diagnosis. Methods: A total of 133 patients who presented at the urology clinic due to ED have veno-occlusive dysfunction (VOD) detected as a result of PCDU and underwent cavernosography for further assessment when scheduled for penile embolization. The results obtained were retrospectively evaluated. Results: The mean age of 133 patients with VOD identified as a result of PCDU was 48.7 +/- 11.2 years. In cavernosography performed after PCDU, venous leakage was detected in 127 patients (95.49%), while no leakage was found in six patients (4.51%). Bilateral venous leakage was found in 91.34% (n:116), right venous leakage in 5.51% (n:7), and left venous leakage in 3.15% (n:4) of the patients with venous leakage. Conclusion: Evaluating the cavernosography results, PCDU alone is often sufficient to diagnose veno-occlusive ED. Cavernosography is a more invasive diagnostic method compared to PCDU that is adequate in cases where venous surgery or embolization is not considered, and cavernosography is not recommended in these patients.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 Fistulisation of pyogenic liver abscess into the portal vein and bile ducts(Singapore Medical Assoc, 2011) Aydin, C.; Kayaalp, C.; Kutlu, R.; Yilmaz, S.We report pyogenic liver abscess complicated by fistulisation into the portal vein and bile ducts in a 58-year-old diabetic woman, who was admitted to the hospital with fever, chills and rigors. Abdominal ultrasonography and computed tomography demonstrated a 7-cm multiloculated abscess in segment III, close to the left branch of the portal vein. The abscess was drained under fluoroscopic guidance in a single pass. Pus was aspirated, and diluted water-soluble contrast was injected into the cavity. Early films revealed filling of the cavity. Later, the contrast appeared in the bile ducts and left branch of the portal vein. Radiological intervention was discontinued. Immediate surgery, including left lateral segmentectomy, was performed. The preoperative course was uneventful, except for superficial surgical site infection. We opine that a hepato-venous fistula is an indication for surgical intervention, and that early resection of the fistula can prevent severe septic complications.Öğe Long-term outcomes of liver transplantation for primary sclerosing cholangitis(Lippincott Williams & Wilkins, 2022) Harputluoglu, M.

Thrombosis is a possible complication of using expanded polytetrafluoroethylene (e-PTFE) grafts. Herein, we report on 3 cases of liver recipients who died of intermittent sepsis episodes emerged concurrently with the thrombosis in synthetic vascular grafts and inferior vena cava (IVC) vein. Right lobe liver transplantation from living donors was performed for 3 patients by using e-PTFE grafts between the liver and IVC. Although heparin had been administered, thrombosis was developed in vascular graft and IVC extending to the right atrium; it was developed within 1-4 months of transplantations. All 3 patients suffered from recurrent sepsis episodes (4, 5, and 6 attacks for each patient) by different multidrug-resistant bacterial species. Treatment attempts including thrombolytic and antimicrobial drugs made, and surgical, endoscopic and radiological interventions could not resolve the clinical situation. The patients died of septic complications. We concluded that severe recurrent sepsis attacks may develop in liver transplant recipients when IVC and synthetic vascular graft were thrombosed. Removing the e-PTFE graft may be benefit for the treatment.Öğe Retained Foreign Body in Transplanted Liver(Avicenna Organ Transplant Center, 2015) Kayaalp, C.; Kirmizi, S.; Kutlu, R.; Yagci, M. A.; Isik, B.; Yilmaz, S.Liver transplantation is a technically complex and long surgical procedure. A large quantity of various materials such as catheters, sutures, needles and clips are frequently used during the procedure. These materials may enter in the liver from the vascular or biliary orifices inadvertently. A 50-year-old patient who had hepatic failure due to HBV underwent a deceased-donor liver transplantation. The deceased donor was a 75-year-old HbsAg(+) man. The recipient had subfebrile fever and leukocytosis post-operatively. A control computed tomography revealed a cuneiform ischemic area, and a foreign body inside the right anterior portal vein branch proximal to this ischemic region. A 10-F Nelaton catheter, 5-cm long, was removed from the portal vein by surgery. Retrospectively, we understood that the portal vein was cut during the back-table procedure and the portal vein catheter was replaced with a larger one for better irrigation. Most probably, the original catheter was cut together with the portal vein, and the tip of the catheter was retained in the portal system and migrated into the liver. As far as we know, such a complication of liver transplantation has never been described previously.Öğe Venous Outflow Obstruction Following Living Donor Liver Transplantation: Analysis of 1011 Liver Transplant Cases(Lippincott Williams & Wilkins, 2017) Koc, S.; Akbulut, S.; Soyer, V; Yilmaz, M.; Barut, B.; Kutlu, R.; Yilmaz, S.[Abstract Not Available]
