Trash Feet and Mesenteric Ischemia as a Rare Manifestation of a Complicated Abdominal Aortic Aneurysm: A Case Report.

Abstract

Background: Abdominal aortic aneurysms and atheromatous plaques are well-established potential culprits in the development of cholesterol embolization. This embolic phenomenon can result in the occlusion of peripheral arteries in the forefoot or toes, commonly referred to as "trash foot".

Case: A 61-year old patient exhibited severe symptoms and signs of lower limb and mesenteric ischemia, represented clinically by abdominal pain, hematochezia, and bilateral plantar necrotic lesions, attributed to embolization from a previously unknown large infrarenal abdominal aortic aneurysm. Diagnosis was confirmed by performing angio-CT of the abdomen, an angiologic examination, as well as colonoscopy. The patient underwent open surgical repair of the aortic aneurysm and received intravenous prostanoids, resulting in a successful outcome with resolution of bowel ischemia and complete recovery of bilateral foot lesions with no tissue loss.

Conclusion: Cholesterol embolization syndrome seldom manifests with its complete clinical spectrum. Identifying and addressing the underlying cause is crucial, with a focus on potential abdominal aortic aneurysms. A combined approach involving surgical repair and prostanoid therapy may offer a viable option for patients experiencing severe manifestations.
