Treatment for femoral pseudoaneurysms.

Femoral pseudoaneurysms may complicate up to 8% of vascular interventional procedures. Small pseudoaneurysms can spontaneously clot, but sometimes definitive treatment is needed. Surgery has traditionally been considered the 'gold standard' treatment, although it is not without risk in patients with severe cardiovascular disease. Less invasive treatment options such as Duplex ultrasound-guided compression and percutaneous thrombin injection are available, however, evidence of their efficacy is limited. This is an update of a Cochrane review first published in 2006.
