Objective:
The aim of this study was to clarify risk factors and outcome of hepatic arterial complication after living-donor liver transplantations (LDLT).
Methods:
From 2004 to 2010, 522 consecutive LDLTs were performed. We used univariate and multivariate analysis to identify the risk factor on a retrospective basis, and then analysis was performed for adult cases. Hepatic arterial complication included thrombosis, stenosis, and pseudoaneurysm.
Results:
The arterial complication rate was 4.79% (25 cases). Each complication was 9 thromboses, 14 stenoses, and 2 pseudoaneurysms. Preoperative hemoglobin was significantly associated with thrombosis (P = .021), and arterial size with stenosis (P = .037). We could not find any association between arterial complications and biliary stricture. However, the outcome of biliary stricture treatment was associated with arterial stenosis. Of 9 cases with thrombosis, 7 patients underwent rearterialization and 2 were treated with low-molecular-weight heparin (LMWH). Of 14 stenosis cases, 2 patients were treated with the use of balloon dilatation, 10 patients were observed under LMWH, and 2 patients underwent retransplantation. In cases of pseudoaneurysm, 1 patient underwent revision of the aneurysm and the other was observed.
Conclusions:
In our cohort, preoperative low hemoglobin level was a risk factor for thrombosis and artery size a risk factor for stenosis.
