Percutaneous Transluminal Angioplasty of Hepatic Artery Stenosis in Patients After Orthotopic Liver Transplantation: Mid-term Results
- Institute for Clinical and Experimental Medicine, ZRIR IKEM, Department of Diagnostic and Interventional Radiology (Czech Republic)
Purpose: This study was designed to present our experience with percutaneous treatment of hepatic artery stenosis in orthotopic liver transplant patients and to evaluate the efficacy, technical outcomes, and mid-term clinical results of the procedure. Methods: Twenty-two percutaneous transluminal angioplasties (PTAs) were performed in 19 liver transplant recipients at our institution between 1998 and 2010. Stents were placed into the hepatic/celiac artery in 16 PTAs, but balloon dilatation alone was performed in 6 because of the anatomical condition of the vessel. PTA/stenting was indicated in 17 patients because of elevated liver enzymes; 2 patients were asymptomatic. The objective of treating stenosis was prevention of long-term complications, including thrombosis. Results: Technical success was achieved in all patients. There was only one complication: dissection of the treated artery without any subsequent adverse effects. In all patients, elevated liver enzyme levels improved after treatment. No restenosis was observed in any patient during a mean follow-up of 2.6 years (1 month to 5.5 years). Conclusions: Percutaneous angioplasty/stent placement is a safe method for the treatment of hepatic artery stenosis after orthotopic liver transplantation, with a high technical success rate and promising mid-term results.
