  • Title: Percutaneous transhepatic portal vein angioplasty and stent placement after liver transplantation: early experience.
    Author: Olcott EW, Ring EJ, Roberts JP, Ascher NL, Lake JR, Gordon RL.

    Abstract:
    In four patients who underwent liver transplantation, portal vein thrombosis was associated with esophageal varices and significant gastrointestinal bleeding. In a fifth liver transplant patient, portal vein stenosis was suspected when evidence of hepatic ischemia was revealed at liver biopsy. Four patients were treated with percutaneous transhepatic portal vein angioplasty. Percutaneous recanalization was precluded by technical factors in the remaining patient. Early in the series, one patient required surgical excision of what proved to be a thick cuff of fibrous tissue and lymph nodes after angioplasty failed to widen the stenosis significantly. Later, a patient with residual stenosis was treated successfully by means of intravascular stent placement. Of the four patients treated, three eventually died secondary to multiple problems unrelated to the percutaneous procedure. This early experience suggests that transhepatic portal vein interventions are feasible in patients who have received liver transplants and may prove useful at least in the early postprocedure period.
