[Visceral artery aneurysms].

Abstract

The purpose of this article is to review the etiology, clinical presentation and treatment options of visceral artery aneurysms (VAA) on the basis of our experiences. Visceral artery aneurysms are uncommon lesions with a frequency of 0,1-0,2 % in autopsy statistics. In fact many visceral artery aneurysms still present first with a rupture (22 %) and despite emergency laparotomies the mortality rate is about 8,5 %. The course of disease often is disastrous due to rupture of the aneurysms or thromboembolic complications, emphasizing the importance to be aware of this differential diagnosis of abdominal pain. This article covers 9 patients with VAA. 3 patients each revealed an a. lienalis aneurysm and a. gastrica aneurysm, resp. In the other 3 patients an aneurysm of the a. gastroepiploica, the a. pancreatico-duodenalis and the a. mesenterica superior resp. was proven. In 8 of 9 patients a surgical therapy of the VAA took place. Only 2 patients (22 %) were interventionally treated. 1 patient deceased due to postoperative hemorrhage. Both the surgical and the radiological intervention therapy are available for treatment of the VAA. The decision on the choice of the therapeutic procedure should be made on an individual basis.
