[A case of common femoral artery occlusion after homeostasis using device at carotid artery stenting]

The hemostatic puncture closure device Angio-Seal is a quick and easy-to-use system, allowing rapid sealing of the vascular access site after interventional procedure. The rate of complications associated with the use of this device has been reported to be low; nonetheless, certain specific complications may arise. In the present study, we describe a case of vascular occlusion that occurred because of the use of the Angio-Seal device. A 59-year-old man with no sign of peripheral arterial occlusive disease underwent carotid artery stenting. The left common femoral artery was closed with the Angio-Seal device. After 7 days, the patient complained of intermittent claudication, especially while climbing up the stairs. Angiography of the left iliac artery at 2 months after carotid artery stenting revealed occlusion of the left common femoral artery. Deep and superficial femoral arteries were fed by the collateral flow from the muscle branch. Because the patient's symptom was mild and his daily life was not affected, he was treated conservatively. In conclusion, arterial closure performed using a hemostatic device is associated with a risk of vascular occlusion.
