Correction of extrahepatic portal vein thrombosis by the mesenteric to left portal vein bypass.

摘要: OBJECTIVE The goal of this study was to determine the effectiveness mesenteric vein left portal bypass operation (MLPVB) in correcting extrahepatic thrombosis (EHPVT) children. treatment idiopathic EHPVT has been primarily palliative, whereas MLPVB restores hepatic flow patients with EHPVT. METHODS Thirty-four children symptomatic underwent surgery intent perform and were followed for up 7 years. successful 31 (91%), all whom maintain patent grafts have relief follow-up. All had complete from gastrointestinal bleeding. Patients hypersplenism significant increases platelet leukocyte counts reduction spleen size. Superior increased 119 +/- 66 mL/min before 447 225 (P < 0.0001) after surgery. Postoperative blood graft expressed as a fraction calculated ideal size correlated inversely age 0.001). Left-portal diameter 2.6 1.6 mm 7.3 2.4 2 years 0.002). Liver volume 703 349 cm3 799 351 1 week Prothrombin time improved normal year CONCLUSIONS provides excellent symptoms results liver growth normalization coagulation parameters. This is corrective should be done at early an possible.
