title: Unconventional extrahepatic neovascularization after transplant hepatic artery thrombosis: a case report.
abstract: Liver neovascularization preserves hepatic function and improves survival in the setting of post-transplant hepatic artery thrombosis (HAT). In this report, we have presented a unique case of a neovascularized liver after subclinical HAT in a 46-year-old liver transplant patient in whom a collateral supply was recruited from three unconventional sources: The right colic, right intercostal, and right inferior adrenal arteries. We propose systematic angiographic evaluation of all potential sources of collateral vessel formation for patients with HAT to accurately assess patient risk and determine the need for further intervention or revascularization.
