Endovascular Embolization with Amplatzer Vascular Plug II for a Giant Hepatic Aneurysm

Abstract

Recently, endovascular treatments and open surgical repairs for visceral artery aneurysms have been reported. However, both approaches have not proven their superiority due to the lack of randomized clinical studies. In this report, the case of a giant hepatic artery aneurysm treated by embolization with a vascular plug and coils was introduced. A woman in her 70s was referred to our hospital because a hepatic artery aneurysm with a size of 80 mm was detected by computed tomography scan. As she had a medical history of necrotic cholecystitis and abdominal incisional hernia, open repair was high risk. There would be a risk of slipping of embolus to the aneurysm if coils were deployed in the proximal side of the hepatic artery aneurysm due to its short length and the wide diameter of the common hepatic artery. Therefore, a vascular plug was chosen. After twice embolization, the blood flow to the hepatic artery aneurysm was completely blocked without ischemic complication.
