Methods In 40 patients after PCI in our institute during the period between May 2002 and December 2003, Angioseal device were used to seal the femoral arterial puncture site. Results All the Angioseal devices were successfully deployed in 40 patients （successful rate： 100%）; the mean time to hemostasis was 45±12 sec; the mean time to ambulate after angioseal closure was 1.9±0.5 hours. No major groin and systemic complication was observed. There was minor groin oozing in 2 cases and small hemotoma in 1 patient. Conclusions Angio-seal closure device of the femoral artery puncture site after a percutaneous coronary procedure is safe. It can shorten the time to hemostasis, leads to early mobilization, and reduce groin complication. The disadvantage is relatively expensive.展开更多
