A case of deep femoral artery aneurysm found with superficial femoral artery aneurysm

Objective: Deep femoral artery (DFA) aneurysms are extremely rare cases of aneurysms that are difficult to diagnose. The objective of this report was to discuss the timing and method of surgery for this disease. Patient: We encountered an asymptomatic left DFA aneurysm that was discovered along with a symptomatic aneurysm of the right superficial femoral artery (SFA). Both sides of the aneurysm were resected with Dacron knitted artificial vascular grafts (Gelsoft™ Plus, Vasctek, UK) simultaneously. Result: After the operation, the right SFA had good blood flow, but the graft of the left DFA was occluded. The occlusion was considered to be caused by insufficient blood flow in the graft. The patient was discharged without any complications. Conclusion: The coexistence of DFA aneurysms should be examined if other aneurysms are found. DFA aneurysms are at a high risk of rupture. Careful follow-up is required, and intervention is recommended when the diameter exceeds 35 mm.
