Management of nonocclusive hepatic artery complications after liver transplantation.
Nonocclusive arterial disease represents less than 5% of posttransplant arterial complications. Nonocclusive arterial complications are classified into (1) nonocclusive diminished flow in the hepatic artery, (2) arteriovenous fistulae, (3) pseudoaneurysms, and (4) arterial rupture. Due to the rarity of these complications, particularly when considering them individually, many of the opinions and managements of these complications are anecdotal. Transcatheter embolization is the main mode of minimal invasive management of these uncommon complications. Other minimal invasive methods have been described such as stent placement or direct percutaneous embolization/thrombosis. The article discusses the presentation, etiology, types, treatment indications, and various modes of minimal invasive therapy used to manage these complications.
