Paclitaxel coated-stent for early-onset thrombosis after liver transplantation

Abstract

Hepatic artery thrombosis (HAT) is the most common vascular complication of orthotopic liver transplantation (OLT) and constitutes a potential emergency during the postoperative period. Surgical revascularization and retransplantation are the treatments of choice for this condition. The aim of this report is to present long-term follow-up on survival and graft function of three patients with paclitaxel-coated hepatic artery stents placed percutaneously after early-onset HAT. Three patients developed early onset HAT after cadaveric-donor OLT in a tertiary care center in Mexico. These patients were treated percutaneously with balloon angioplasty and paclitaxel-coated stents. After 24 months or more of follow-up, 2 patients present total occlusion of the stent and one patient, intra-stent stenosis; interestingly, all patients have normal graft function and excellent quality of life. In conclusion, although balloon angioplasty and stent placement may be a therapeutic option for suitable patients with early-onset HAT after OLT, long-term patency is unlikely even with the use of paclitax-el-coated materials.
