Liver transplant recipients with portal vein thrombosis: a single center retrospective study

摘要: Background Portal vein thrombosis (PVT) used to be a contraindication for liver transplantation (LT). This obstacle has been delt with following the improvement of LT-related techniques and therapeutic approaches thrombosis. But effect PVT on LT outcomes is still controversial. We reviewed retrospectively outcome patients as well risk factors surgical management according grades. Methods A total 465 adult LTs were performed from December 2002 through 2006. Operative findings result preoperative ultrasonography imaging grading (Yerdel grading). Comparison factors, variables associated perioperative period prognosis between recipients without based Results In LTs, 42 operatively confirmed have (9.0%) (19 grade 1, 14 2, 7 3, 2 4). Increased age treatment portal hypertension PVT. Grade 1 or was treated by direct anastomosis single thrombectomy. 3 patients, donor PV directly anastomosed dilated branch recipient venous system distal open superior mesenteric an interposition graft if needed. 4 managed our modified cavoportal hemitransposition technique. The comparison controls showed no significant difference in operative duration blood transfusion (P>0.05). flow rate lower (48.881+/-12.788 cm/s) than (57.172+/-21.715 cm/s, P 0.05); 3-year survival rates 58.8% 56.4% respectively Conclusions not contraindicated it graded. may post-transplantation complications like renal failure rethrombosis, difficulty patient are similar those Development accumulation experience dealing further improve recipients.
