Hepatic artery aneurysm: incidental diagnosis with abdominal ultrasonography and treatment by coil embolization

Abstract

Hepatic artery aneurysm (HAA) was first reported at autopsy in 1809, represents one fifth of visceral aneurysms and the mortality from spontaneous rupture is high in most of cases. We are reporting a case of an asymptomatic 48-year-old woman with an extrahepatic HAA, diagnosed initially and incidentally with abdominal ultrasonography, confirmed by a three-dimensional contrast-enhanced magnetic resonance imaging and angiography. Endovascular treatment was considered feasible and was successfully treated with coil embolization.

Asymptomatic hepatic pseudoaneurysm identified 25 days after knife injury: a case report

“…Once HPA is diagnosed, regardless of its size, the risk of aneurysm rupture and acute hemodynamic compromise requires appropriate treatment [ 8 ]. Endovascular treatment including coil embolization, glue embolization, and angiographic stent placement, is the most common technique in hemodynamically stable patients [ 3 , 9 ].…”

Hepatic Artery Pseudoaneurysm Following Gunshot Injury With Early Rupture

“…Once HAP is diagnosed, a definite intervention, regardless of the size, is warranted as the clinical course of these aneurysms is unpredictable with a possibility of rupture and acute hemodynamic compromise [18]. Diagnosis can be made with different radiological modalities, with ultrasound, contrastenhanced CT scan, CT angiography, contrast-enhanced MRI, and selective angiography being the most valuable investigation modalities for the diagnosis of HAP with a sensitivity of 100% [19]. Incidentally detected HAP can be treated with angiographic stent placement or embolization if feasible.…”
