Common Femoral Artery Aneurysm : A Challenging Diagnostic And Treatment Of A Rare Case

Background: Aneurysm of the peripheral artery is a rare vascular pathology, especially aneurysm in the common femoral artery. Here, we presented a case report of a right common femoral artery aneurysm caused by infection. Objective: This case report is aimed to explore further about the diagnosis process of rare cases in peripheral arteries to elaborate proper treatment for patients with this condition. Case Presentation: a 76-year-old man was referred to our hospital with a pulsatile groin mass at his right thigh. He had no prior history of surgery or traumas, but he has been treated in a private hospital due to septic condition, hypertension, and type II diabetes mellitus. A diagnosis of a common femoral artery aneurysm was made based on findings from physical examination and radiology examination. The patient was referred to the Cardiovascular and Thoracic Surgeon Department and scheduled for routine surgery, but on the third day of admission patient became hemodynamically unstable, and on re-examination, the aneurysm was found had been ruptured. Emergency surgery was conducted on that day. During surgery, the patient was hemodynamically stable with PRC transfusion. The result of aneurysm excision and the bypass was remarkable. Conclusion: The common femoral artery aneurysm is uncommon. When a femoral artery aneurysm is suspected, a search for such aneurysms should be conducted. In this kind of patient, straightforward surgical management yields positive outcomes.
