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.
Highlights
The celiac artery has three branches: the left gastric, splenic and common hepatic arteries
We are reporting a patient asymptomatic with an extrahepatic Hepatic artery aneurysm (HAA), diagnosed incidentally on abdominal US and was successfully treated with coil embolization
The findings suggested HAA, followed by a three-dimensional contrast-enhanced magnetic resonance imaging (MRI) angiography (Figure 2) and contrast angiography which confirmed the diagnosis (Figure 3)
Summary
The celiac artery has three branches: the left gastric, splenic and common hepatic arteries. HAA is the most frequently visceral artery aneurysm and is probably related to the increasing use of percutaneous diagnostic and therapeutic procedures[5]. Hepatic artery aneurysm - Andrade LJO et al. J Vasc Bras 2012, Vol 11, No 3 233 more frequent[6]. We are reporting a patient asymptomatic with an extrahepatic HAA, diagnosed incidentally on abdominal US and was successfully treated with coil embolization. Angiography of celiac trunk and hepatic artery were performed from a right common femoral artery approach, using a 6F Cobra diagnostic catheter (Terumo Europe N.V. Leuven, Belgium) and Ultravist 370 (Bayer HealthCare Pharmaceutical Inc. USA) contrast agent. A post coiling and post-angioplasty angiogram showed complete occlusion of the aneurysm, with the coil occluding the aneurysm This was confirmed by a hepatic artery angiogram (Figure 4). Magnetic Resonance Imaging angiography: three-dimensional volume-rendered image clearly depicts aneurysm
