Abstract

De Bakey and Cooley did the first successful operation for a visceral artery aneurysm (VAA) in 1953 [1]. They are relatively rare and the risk of rupture is associated with high mortality [2-6]. The majority of patients are asymptomatic prior to rupture and the main indication of elective treatment is size; VAA larger than 2 cm and aneurysms in women of childbearing age is recommended [1-7]. The goal of treatment is to prevent aneurysm expansion by excluding it from the arterial circulation saving branchs patency and freedom from rupture or reperfusion [8-10]. Surgery has been considered the treatment of VAA for several decades, but now a days endovascular procedures as embolization or covered stents have increased the treatment options available to comorbid patients not suitable for open repair [7-10].

Highlights

De Bakey and Cooley did the first successful operation for a visceral artery aneurysm (VAA) in 1953 [1]
Angiography remains the “gold standard” in the preoperative imaging and allows concomitant endovascular interventions, determining proper landing zones in the proximal and distal non aneurysmal segments of the artery for stent-grafts, as well as for determining whether the neck morphology is adequate for coil embolization [11] (Figure 2)
VAA can often be excluded from the circulation in this way by coil embolization of first the distal and the proximal segment of the parent artery

Introduction

De Bakey and Cooley did the first successful operation for a visceral artery aneurysm (VAA) in 1953 [1]. The majority of patients are asymptomatic prior to rupture and the main indication of elective treatment is size; VAA larger than 2 cm and aneurysms in women of childbearing age is recommended [1,2,3,4,5,6,7]. The goal of treatment is to prevent aneurysm expansion by excluding it from the arterial circulation saving branchs patency and freedom from rupture or reperfusion [8,9,10].
