Recurrent thrombosis of liver transplant artery: diagnosis and staged minimally invasive treatment

Abstract

The paper presents a clinical study of a 53-year-old patient who underwent liver transplantation complicated by proper hepatic artery thrombosis. No clinical or laboratory signs of the complication were observed. The disruption of arterial blood supply to the transplant was established on day six following surgery by means of routine Doppler ultrasound. Following successful selective endovascular thrombus aspiration and balloon dilation, the arterial blood flow was restored. However, one day later, the thrombosis recurred. Hepatic revascularization was achieved through thrombus re-aspiration and the proper hepatic artery stenting. In the subsequent postoperative period, no complications were observed. The paper analyzes possible causes of thrombosis and recurrent thrombosis, as well as reviewing modern literature.
