A unique proposed etiology for inferior mesenteric artery aneurysm: A case report

Endovascular management of colic artery pseudoaneurysm: A case report of successful intervention in a 59-year-old male with abdominal hematoma

“…IMAP is the rarest form of VAPAs with an incidence of roughly 1% [3 , 5 , 6] . A review done by Obara et al.…”

“…Aneurysms are localized dilatation of a blood vessel in which all 3 layers of the blood vessel wall (intima, media, and adventitia) are dilated [1] . Aneurysms are most commonly seen within the aorta, although they can occur in any blood vessel [3] . Pseudoaneurysms, on the other hand, are false dilatation of blood vessels caused by damage to the arterial wall resulting in contained extravasation of blood [1] .…”

“…Visceral artery pseudoaneurysms (VAPAs) is a broad term for any pseudoaneurysm that affects renal or splanchnic arteries [3] . VAPAs can be caused by disease pathology or iatrogenic injury from catheter-based interventions.…”

“…VAPAs can be caused by disease pathology or iatrogenic injury from catheter-based interventions. They are relatively rare with an overall incidence rate of 0.01%-0.2% [3] , [4] , [5] , [6] . Incidence of aneurysmal disease within visceral arteries is highest within the splenic artery at approximately 60% and lowest within the inferior mesenteric artery at approximately 1% [3 , 5 , 6] .…”

Successful surgical management of a suspected high-flow inferior mesenteric artery aneurysm in a patient with chronic celiac and superior mesenteric artery occlusions

“…4 , 5 , 6 This can lead to increased IMA flow, flow turbulence, arterial wall stress, progressive arterial dilatation, and aneurysm formation. 4 , 7 …”
