- Abstract: Post-liver transplant (LT) hepatic artery vasospasm is a vascular complication that is not well recognized and its incidence is not known. As a possible sequela to vasospasm, hepatic artery thrombosis is the second major cause of allograft failure after primary nonfunction and its reported incidence is 2.9% in adults and 8.3% in pediatric LT. Lacuna in knowledge regarding early hepatic artery vasospasm post-LT makes it a difficult condition to diagnose and treat, as the initial ischemic insult on graft can have devastating consequences. We report a case of pediatric progressive familial intrahepatic cholestasis type 3-related chronic liver disease who underwent cadaveric orthotopic LT and postoperatively developed fever, worsening hypotension, and elevated liver enzymes with an absence of arterial flow in intrahepatic branches on Doppler ultrasound. Suspecting early hepatic artery thrombosis, the patient was re-explored and the graft hepatic artery was found to be in a state of vasospasm. Following the infusion of intra-arterial papaverine, urokinase, and intravenous nicorandil, there was an improvement in blood flow. The patient responded well and was discharged on postoperative day 23 with normal liver enzymes.
