- W1991389466 abstract "To evaluate the efficacy of hepatic artery percutaneous transluminal angioplasty (PTA) in the treatment of hepatic artery stenosis (HAS).A retrospective analysis was performed of all cases of HAS documented by angiography from January 1995 to June 2003 at the authors' institution. Management was evaluated and long-term patency was documented by Doppler ultrasonography. The patency, restenosis, and hepatic artery thrombosis (HAT) rates were determined by the Kaplan-Meier method. The technical success of hepatic artery PTA was stratified according to the location of the stenoses relative to the anastomosis, as well as by the presence of associated hepatic arterial kinks.Thrombosis was seen in 65% +/- 13% of untreated HAS cases within 6 months. Stenotic lesions without associated arterial kinks had an improved technical success rate and a reduced complication rate of 94% and 10%, respectively, compared with lesions with associated hepatic arterial kinks treated with hepatic artery PTA (14% and 29%, respectively). The 1-year primary and primary assisted patency rates of hepatic artery PTA for all lesions were 44% +/- 12% and 60% +/- 11%, respectively, and were 65% +/- 10% and 80% +/- 8%, respectively, for lesions not associated with hepatic arterial kinks. The 1-year HAT rate and restenosis rate after hepatic artery PTA were 19% +/- 10% and 32% +/- 11%, respectively. The 1-year primary assisted patency rate for hepatic artery PTA with repeat PTA performed for restenosed lesions and surgical revascularization performed for failed PTA was 74% +/- 10%.Untreated HAS carries a high morbidity rate. Hepatic artery PTA can play a large role in the management of HAS by reducing the HAT rate more than threefold. With appropriate lesion selection, hepatic artery PTA will have better patency rates than those associated with hepatic artery stent placement." @default.
