Les anévrismes des artères digestives. À propos d'un cas clinique de localisation anévrismale multiple et revue de la littérature

Visceral artery aneurysms constitute a rare vascular disease, with a risk of rupture associated to a high mortality. Often asymptomatic, they are discovered following a routine radiological examination. We present the case of a 71-year-old patient with multiple aneurysms involving the celiac trunk, the splenic artery, and the common hepatic artery. The surgical treatment consisted of an aortohepatic bypass using polytetrafluoroethylene prosthesis, after exclusion of all the aneurysms. The angiography and postoperative angioscan demonstrated the perfect patency of the prosthesis, totally excluding the aneurysms. Given the variety of presentations and the absence of precise predictive factors, there is no therapeutic consensus so far. Surgery is the first therapeutic choice. Endovascular treatment by angioembolization must be reserved for particular conditions. The purpose of this article is to propose the best therapeutic approach on the basis of evidence in the literature.
