Femoral aneurysm

Femoral aneurysm

True aneurysm of the femoral artery is uncommon. Complications occur in less than 3% so conservative treatment is generally indicated, but it is important to look for aneurysms elsewhere as over half are associated with abdominal or popliteal aneurysms. Large aneurysms should be repaired. False aneurysm of the femoral artery occurs in 2% of patients after arterial surgery at this site. Local repair may involve reanastomosis of the bypass in the groin under suitable antibiotic cover. However, if infection is the cause, the treatment may involve excision of the infected graft and insertion of a further bypass routed around the infected area. In the latter case, the failure rate is high, and limb loss may be unavoidable. For false aneurysms caused by femoral artery puncture measuring ≤ 3 /uni00A0 cm, thrombin injection under ultrasonography guidance may be successful and avoids surgery . False aneurysms measuring >3 /uni00A0 cm usually require open surgical repair with suturing of the puncture site. -
