Spontaneous Pseudoaneurysm of the Left Superficial Femoral Artery: An Unusual Case Report and Review of Literature

Abstract

Pseudoaneurysms are rare to occur and the rarest to occur in those who have not undergone surgical/endovascular procedures like catheterization. Such pseudoaneurysms are known as spontaneous pseudoaneurysms which are very less reported and reviewed. This generally occurs due to underlying pathological causes, the most common being atherosclerotic disease. The most common clinical presentation is a femoral artery pseudoaneurysm. Other less common presentations include aortic and visceral pseudoaneurysms. We describe here the occurrence of a pseudoaneurysm in a patient who has no history of endovascular procedures in the past and has a pseudoaneurysm showing a secondary change along with superadded infection of Acinetobacter baumannii. The case was radiologically diagnosed by a computed tomography scan of the abdomen and thigh, after which a surgical excision of the pseudoaneurysm was performed and the specimen was sent for the histopathological examination, which revealed secondary changes.
