Number of patientsPrevalence PVT, n (%)PVT characteristicsOutcomes
Englesbe et al[65]22291 (2001-2007)897 (4.02)Not describedPVT was not predictive of waiting list mortality (HR = 0.90, P = 0.23)
PVT was predictive of post-transplant mortality (HR = 1.32, P = 0.02)
Sringeri et al[61]1491 (2000-Aug 2012)119 (8.0)Not describedProlonged theatre timea, increased blood transfusion rates1. No difference mortality up-to 140 mo
Ravaioli et al[13]889 (1998-2008)91 (10.2)Partial 51 (56%)No difference 1 yr (85% vs 86%) and 5 yr (68% vs 73%) survival between PVT and non-PVT subjects
Complete 40 (44%)Survival improved significantly for patients with complete PVT in the second era (2003-2008) (57% vs 89% at 1 yr1)
Yerdel et al[15]779 (1987-1996)63 (8.1)Grade 1: 24,Reduced 5 yr survival between PVT and non-PVT subjects (65.3% vs 76.3%1)
Grade 2: 23,
Grade 3: 6,But improved 5 yr survival from 1st to 2nd era in all patients (from 72% to 83%1)
Grade 4: 10
