A patient with femoral artery pseudoaneurysm treated with ultrasound‐guided injection of an exogenous lyophilized human fibrin sealant

A femoral artery pseudoaneurysm (FAP) is a serious complication of arterial injury. It can cause compression of the surrounding nerves and tissues, rupture and bleeding of the aneurysm, and formation and dislodgement of thrombi, and can lead to distal limb embolism, tissue necrosis, and infection. Computed tomography angiography and ultrasonography are the preferred techniques for diagnosis of FAP. This report describes the successful treatment of an FAP using an ultrasound-guided percutaneous intracavitary injection of a lyophilized human fibrin sealant. This treatment was safe, associated with minimal pain and complications, and clinically effective.
