Acute lower limb ischemia caused by repeat deployment of vascular closure device.

Vascular closure devices are used to facilitate faster hemostasis and earlier ambulation, improve patient comfort, and reduce length of hospital stay after percutaneous endovascular procedures. However, their use may rarely be associated with limb ischemia due to endothelial damage and arterial thrombosis. This report illustrates the case of a patient who experienced acute lower limb ischemia due to superficial femoral artery occlusion caused by repeat closure with Angio-Seal vascular closure device within 30 days in a small-caliber superficial femoral artery. The patient was surgically treated by vascular repair with a synthetic graft, and remains symptom-free in 3-year follow-up. Repeat deployment of vascular closure devices in the same access site within a period of 30 days may cause acute limb ischemia due to arterial thrombosis, especially in patients with small-caliber arteries, even in the absence of evident risk factors.
