Visceral artery aneurysms are rare but serious vascular conditions. Early diagnosis and surgical management, primarily elective, are crucial for saving lives and improving patient outcomes.

Area of Science:

Vascular Surgery
Interventional Radiology
Abdominal Imaging

Background:

Visceral artery aneurysms (VAAs) are uncommon vascular malformations with limited comprehensive literature.
Existing knowledge gaps necessitate a review of clinical experiences in diagnosing and treating VAAs.

Purpose of the Study:

To review institutional experiences in the diagnosis and treatment of visceral artery aneurysms.
To analyze patient outcomes following various treatment modalities for VAAs.

Main Methods:

Retrospective review of 10 patients diagnosed with VAAs between June 2002 and September 2005.
Analysis of clinical, pathological, and postoperative data, including outcomes.

Main Results:

Related Experiment Videos

13 VAAs identified in 10 patients: 4 splenic, 2 hepatic, 5 renal, 1 superior mesenteric, and 1 inferior mesenteric artery aneurysm.

Predominantly treated surgically (ligation/exclusion or resection/revascularization); one endovascular treatment (coil embolization).

Atherosclerotic changes were the primary histopathologic finding; no mortality occurred, though one patient required bleeding revision.

Conclusions:

Visceral artery aneurysms are rare, potentially life-threatening vascular disorders.
Increased diagnosis rates are attributed to advanced imaging and screening.
Prompt diagnosis and management are essential for positive patient outcomes.
