Case report: pseudoaneurysm of transplant hepatic artery: a late presentation.

Vascular problems of the hepatic artery account for about 10% of graft loss after liver transplantation (Todo et al, 1987). Of these the majority are secondary to hepatic artery thrombosis (Tobben et al, 1988). In a large survey of transplants, only a small percentage were found to fail as a result of pseudoaneurysm, often at the anastomotic site, and 25% of these were related to infection (Tobben et al, 1988). The potential for early rupture and fatal haemorrhage makes early diagnosis important. In a review of the literature pseudoaneurysms are seen as an early complication and have not been described later than six months (Wozney et al, 1986; Houssin et al, 1988; Tobben et al, 1988; Zayko et al, 1988). We report a late presenting pseudoaneurysm in which no evidence of infection was demonstrated. The importance of early diagnosis and the value of ultrasound are stressed. A 36-year-old female who had required an orthotopic liver transplantation for primary biliary cirrhosis 24 months previously presented ...
