Exclusion of infected pseudoaneurysm of modified Blalock Taussig shunt using a covered stent.

A pseudoaneurysm due to infection after a modified Blalock-Taussig shunt is a rare but potentially fatal complication that can rupture, compress mediastinal structures, produce shunt occlusion, and bacteremia. In these patients, medical management of endocarditis is often incomplete because of the presence of prosthetic material and requires the take down of the shunt, most often by surgery, which can be technically challenging. We outline the use of a covered stent to exclude pseudoaneurysm from circulation.
