Hepatic arterial vasospasm can be a potential vascular complication after liver transplantation and can manifest as hepatic artery thrombosis. Due to scarcity of the literature on this pathology, its incidence, mechanism, relevance, diagnosis, and prognosis remain to be investigated. Our index case, a 64 year man with decompensated alcohol related cirrhosis underwent cadaveric orthotropic liver transplant and was having a normal post-operative course. On post-operative day 12, liver enzymes were elevated and Doppler ultrasound performed showed hepatic arterial occlusion. In view of hepatic artery thrombosis digital subtraction angiography (DSA) was done, which showed string bead appearance of graft hepatic artery, with no thrombosis or stenosis of hepatic artery anastomosis. It was managed by oral administration of vasodilator as well as intra-arterial administration of vasodilators through DSA catheter tip placed in hepatic artery. He responded well to the management and was discharged on post-operative day 24 with normal liver enzymes.
