Successful treatment of a rare 6.5-cm true profunda femoris artery aneurysm with aneurysmectomy and interposition bypass

Profunda femoris artery aneurysms (PFAAs) are rare and account for only 0.5% of all peripheral artery aneurysms. Potential complications include compression of surrounding nerves and veins, limb ischemia, and rupture. Currently there are no guidelines on the management of true PFAAs, and suggested treatment modalities include endovascular, open, and hybrid approaches. We report a case of an 82-year-old male with a history of aneurysmal disease who presented with a symptomatic 6.5-cm PFAA. He underwent successful aneurysmectomy and interposition bypass, which remains an effective method for treatment of this rare pathology.
