“…PTV can be performed with a percutaneous transluminal approach (i.e., transjugular or transfemoral approach), and both of these approaches are technically easy. 8 Carneval et al 25 recommended that strictures be dilated with balloons to 110%-130% of the diameter of the normal vein. As a result, three children (25%) with hepatic vein obstruction were treated with venoplasty, and 9 (75%) were treated with stent placement.…”

“…An important factor for the success of liver transplantation is the patency of vascular reconstruction to allow effi cient perfusion and drainage of the transplanted organ. 3 Hepatic venous outfl ow obstruction is a relatively uncommon but important complication after liver transplantation. 4 When it occurs, hepatic congestion can lead to massive ascites and hepatic dysfunction.…”

How to cite this article: Shibata T. Interventional radiology for post-transplant anastomotic complications. Hepatoma Res 2017;3:221-7.The effectiveness of percutaneous interventional radiology for anastomotic stricture in hepatic vein, portal vein, and biliary tract after living donor liver transplantation (LDLT) is described. As a number of patients with LDLT are infants < 10-year-old in the study, the first treatment option was balloon dilatation, not primary stenting. However, stent placement was performed in patients with recurrent, repeated stenosis. Key words:Interventional radiology, living donor liver transplantation, balloon dilatation, stent placement ABSTRACTArticle history:

Сеченова» Минздрава России, Москва, Российская Федерация Введение. Трансплантация печени -многокомпонентный, сложный вид оперативного лечения. У паци ентов, перенесших такое лечение, могут наблюдаться различные осложнения. Одним из таких ослож нений является нарушение портального кровотока на фоне стеноза воротной вены. Материалы и ме-тоды. Спустя 6 лет у ребенка после трансплантации фрагмента печени отмечалось прогрессирование признаков портальной гипертензии (варикозно расширенные вены пищевода (ВРВП) 3й ст., выраженная спленомегалия). Функция трансплантата оставалась удовлетворительной, однако по результатам допол нительного обследования диагностирован стеноз воротной вены. Результаты. В результате проведенной коррекции портального кровотока у пациента отмечена положительная динамика. По данным лабора торноинструментальных методов обследования функция трансплантата нормальная, отмечено восста новление адекватного кровотока по воротной вене (свыше 80 см/с), регрессия признаков портальной гипертензии. Выводы. Ультразвуковое дуплексное сканирование трансплантата в сочетании с МСКТ ангиографией позволяет своевременно и достоверно выявить стеноз воротной вены. Чрескожночрес печеночное стентирование воротной вены -малоинвазивный и высокоэффективный метод коррекции портальной гипертензии. Антиагрегантная терапия под контролем агрегации тромбоцитов является не обходимым условием для успешной функции стента. Introduction. Liver transplantation is a multicomponent and complex type of operative treatment. Patients undergoing such a treatment sometimes are getting various complications. One of these complications is a portal hypertension associated with portal vein stenosis. Materials and methods. In 6 years after the left lateral section transplantation from living donor in a pediatric patient the signs of portal hypertension were observed. Stenosis of the portal vein was revealed. Due to this fact percutaneous transhepatic correction of portal vein stenosis was per formed. Results. As a result of the correction of portal blood flow in the patient a positive trend was noted. Accor ding to the laboratory and instrumental methods of examination the graft had a normal function, portal blood flow was adequate. In order to control the stent patency Doppler ultrasound and MSCT of the abdominal cavity with intravenous bolus contrasting were performed. Due to these examinations the stent function was good, the rate of blood flow in the portal vein due to Doppler data has reached 80 cm/sec, and a decrease of the spleen size was noted.
