Abstract

BACKGROUND:

The risk of hepatic artery thrombosis after orthotopic liver transplantation is higher in cases of poor hepatic arterial inflow, small or anomalous recipient hepatic arteries, unsafe native hepatic arteries.

AIMS:

To assess the use of arterial conduits as alternative technique for graft revascularization.

PATIENTS:

At the Liver Transplant Center of the "S. Giovanni Battista" Hospital in Torino, a review has been made of 600 consecutive orthotopic liver transplantations in 545 adult patients from 1990 to 1999.

METHODS:

In 95 orthotopic liver transplantations (15.8%) in 88 patients, the graft was supplied by infrarenal conduit, while in 505 orthotopic liver transplantations (84.2%) in 457 patients, a direct anastomosis was used.

RESULTS AND CONCLUSIONS:

The overall incidence of hepatic artery thrombosis in our series was 3.5% (21/600): 5.3% (5/91) for conduits and 3.2% (16/505) for standard technique (p=ns, chi2 test). The actuarial 5-year graft survival was 67.7% for conduits and 68.6% for the standard technique; p (log rank): ns. The iliac prosthesis torsion was the only complication related to the use of infrarenal iliac conduit. The arterial conduit, performed with donor iliac artery, is an effective and safe revascularization technique in patients at high risk of arterial thrombosis.
