Current management strategies for visceral artery aneurysms: an overview

Abstract

Visceral artery aneurysms (VAAs) are rare and affect the celiac artery, superior mesenteric artery, and inferior mesenteric artery, and their branches. The natural history of VAAs is not well understood as they are often asymptomatic and found incidentally; however, they carry a risk of rupture that can result in death from hemorrhage in the peritoneal cavity, retroperitoneal space, or gastrointestinal tract. Recent advances in imaging technology and its availability allow us to diagnose all types of VAA. VAAs can be treated by open surgery, laparoscopic surgery, endovascular therapy, or a hybrid approach. However, there are still no specific indications for the treatment of VAAs, and the best strategy depends on the anatomical location of the aneurysm as well as the clinical presentation of the patient. This article reviews the literature on the etiology, clinical features, diagnosis, and anatomic characteristics of each type of VAA and discusses the current options for their treatment and management.

Ligation of symptomatic celiac artery aneurysm without vascular reconstruction: Utilizing the natural collateral circulation of the celiac axis: A case report

“…Ligation without reconstruction is commonly performed in case of emergent situations like spontaneous rupture. Ligation and excision can be considered in elective situations only after confirmation of adequate collateral circulation from the branches of Superior Mesenteric Artery (SMA) [ 13 ]. However, there have been very few reports of surgical treatment of CAA without revascularization in elective situations.…”

A systematic review and meta‐analysis of the performance of flow‐diverting stents in the treatment of peripheral and visceral artery aneurysms

“…In selected cases, the grafted stent could provide effective exclusion of an aneurysm while maintaining the patency of the parent vessel. However, this technique, though with an encouraging technical success rate of 96%, 25 is often limited by the local anatomy of the lesion, due to the requirement for adequate landing zones and its high profile and rigid delivery system 26 …”

A case of splenic artery pseudoaneurysm rupture presenting as rectal bleeding in a regional hospital

“…SAP differs from a true aneurysm histologically in that a collection of blood forms between the tunica media and tunica adventitia rather than a circumferential dilation of the entire vessel wall. This usually reflects an underlying process of vessel wall weakening through traumatic, inflammatory, infective or iatrogenic causes [ 3 ].…”
