The most consistent procedural predictor of vascular access site complications thus far has been the intensity and duration of anticoagulant therapy during and after percutaneous coronary interventions (PCI). Several devices have been developed to aid in the closure of the femoral arteriotomy. This report describes the clinical outcome of unsuccessful deployment of femoral closure devices in a cohort of 285 consecutive patients who underwent PCI and were treated with platelet glycoprotein (GP) IIb/IIIa inhibitors. Manual femoral artery compression was used in 123 patients, Perclose in 123 patients, and AngioSeal in 39 patients. Successful homeostasis was achieved in 98.4% of patients who received manual compression, in 91.9% of the Perclose‐sealed arteriotomy, and in 84.6% of patients who received the AngioSeal closure device (P = 0.004). The incidence of vascular complications after successful …
