UNASSIGNED: Objective   The @entity5033 ( @entity5033 ) and liver transplantation (LT) have changed the scenario of extrahepatic @entity6315 (EHPVO) since the @entity5033 , the only "curative" technique, can now be offered in asymptomatic @entity1 and also @entity715 complications of LT have increased the incidence of EHPVO. Material and Methods   A retrospective study of @entity1 undergoing surgery for EHPVO was conducted between 1990 and 2015. An analysis was done for the shunt permeability and clinical evolution over time. Results   Of the 73 @entity1 with EHPVO, 39 were operated (12 posttransplant and 27 idiopathic). The median age at surgery was 9.36 years (range, 1.60-17.42 years). The @entity5033 was the technique of choice; it was offered in 21 @entity1 but eventually could be performed in only 18 (9 posttransplant and 9 idiopathic). The results of @entity5033 were better in idiopathic (just one @entity715 successfully converted into mesocaval bypass). In the @entity5033 after LT (n   =   9), six shunts are permeable, two became @entity715 (one @entity1 requiring retransplantation), and one late @entity715 occurred and the @entity1 died eventually because of @entity360 . In the remaining @entity1 (21 out of the 39), @entity5033 was not performed because of intrahepatic cavernoma, @entity6315 , or insufficient length of vascular graft (especially in left lateral segment graft LT, since the portal vein is usually located in the right upper quadrant). They underwent 10 @entity5033 ( @entity5033 ) (1 posttransplant and 9 idiopathic), 5 proximal splenorenal shunts (PSRS) (1/4), 6 mesocaval shunts (1/5), and 1 modified Sugiura procedure. The results with @entity5033 have been favorable (one @entity715 , converted into mesocaval bypass). In the PSRS no @entity715 was identified and in the mesocaval shunt one early @entity715 occurred. Posttransplantation group had higher risk of shunt @entity715 , regardless of the surgical technique (chi-square, 0.021). The total increase of platelets after 6 months was not different in @entity5033 as compared with other surgical techniques (analysis of variance, 0.110). Conclusions   The @entity5033 is the technique of choice in EHPVO for idiopathic @entity715 as well as secondary to LT. Not all cases are favorable for @entity5033 , so the surgeon must consider the possibility of alternative techniques for EHPVO. The results in terms of shunt patency are much better in idiopathic cavernoma that posttransplant @entity1 .
