Background.Chronic, obliterative portal vein (PV) thrombosis (PVT) represents a relative contraindication to liver transplantation (LT) in some centers. When PV thromboembolectomy is not feasible, alternative techniques (portacaval hemitransposition, portal arterialization, multivisceral transplantation) are associated with suboptimal outcomes. In cases where a chronically thrombosed PV has become obliterated, we developed PV recanalization (PVR)-transjugular intrahepatic portosystemic shunt (TIPS) to potentiate LT.We evaluated the impact of PVR-TIPS on liver function, transplant eligibility, and long-termoutcomes after LT. Methods. Forty-four patients with chronic obliterative main PVTwere identified during our institutional LTselection committee. After joint imaging review by transplant surgery/radiology, these patients underwent PVR-TIPS to potentiate transplant eligibility. Patients were followed by hepatology/transplant until LT, and ultimately in posttransplant clinic. The TIPS venography and serial ultrasound/MRI were used subsequently to document PV patency. Results. The main PV (MPV) was completely thrombosed in 17 of 44 (39%) patients; near complete (>95%) occlusion was noted in 27 of 44 (61%) patients. Direct transhepatic and transsplenic punctures were required in 11 of 43 (26%) and 3 of 43 (7%) cases, respectively. Technical success was 43 of 44 (98%) cases. At PVRTIPS completion, persistence of MPV thrombus was noted in 33 of 43 (77%) cases. One-month TIPS venography demonstrated complete resolution of MPVthrombosis in 22 of 29 (76%)without anticoagulation. Thirty-six patients were listed for transplantation; 18 (50%) have been transplanted. Eighty-nine percentMPVpatency rate and82%survival were achievedat 5 years. Conclusions.The PVR-TIPS may be considered for patients with obliterative PVTwho are otherwise appropriate candidates for LT. The high rate ofMPV patency post-TIPS placement suggests flow reestablishment as the dominantmechanism of thrombus resolution.
