Suture knot embolism--a rare complication of percutaneous arterial closure device.

Percutaneous closure devices used after percutaneous endovascular procedures have become more popular over the past decade. Occlusive vascular complication of the device is rare but always leads to limb-threatening consequence. We report a case of arterial occlusion caused by distal embolization of the suture material in the percutaneous closure device.
