A Case of Two-Stage Treatment of a Left Colic Artery Aneurysm and Marginal Artery Aneurysm with Severe Stenosis of the Celiac and Superior Mesenteric Arteries

Abstract

The patient is a 55-year-old woman. Enhanced contrast computed tomography (CT) was conducted to comprehensively assess the renal deformity, revealing a severe stenosis in proximity to the celiac artery (CA) and the point of origin of the superior mesenteric artery (SMA), as well as dilatation of the inferior mesenteric artery (IMA), an aneurysm of the left colic artery (LCAA), and a limbal aneurysm of the splenic flexure arcades. To address the LCAA, coil embolization was performed, and a two-stage bypass of the SMA was carried out to enhance blood flow to the visceral arteries, leading to IMA dilation amelioration.
