Simultaneous bilateral deep femoral artery aneurysms: case report of a rare peripheral arterial aneurysm

Deep femoral artery aneurysms are very rare; particularly when isolated and occur simultaneously in both limbs. We report such a case of a misdiagnosed 16-year-old male presenting after hematoma evacuation was attempted for painful swelling in the left groin. Once the diagnosis was confirmed by computed tomography angiography (CTA), an emergency aneurysmectomy with deep femoral artery (DFA) ligation was performed on the left limb. Subsequently, an elective aneurysmectomy with DFA ligation was done for the contralateral limb during the same admission, with no postoperative complications. Echocardiography, performed with suspicion for infective endocarditis as the cause for possible mycotic aneurysm, revealed Chronic Rheumatic Valvular Heart Disease, without evidence of vegetations, abscesses, or intracardiac thrombi. This case report seeks to discuss the patient's clinical presentation, CTA findings, and surgical management in a low-resource setting, underscoring the risks of this rare condition if misdiagnosed.
