Use of FemoStop system for arterial puncture site closure after coronary angioplasty.
Different protocols exist concerning the method and timing of post-coronary angioplasty arterial puncture site closure. Easy handling and good effectiveness are well-documented for the Femostop femoral artery compression system; however, no hard data exist concerning the relationship between heparin anticoagulation level and femoral artery compression time (FSCT). Thus, we prospectively randomized 267 patients after elective percutaneous transluminal coronary angioplasty (PTCA) into two groups [group A (n=137) had early sheath removal 6 to 8 hours after PTCA; group B (n=130) had late sheath removal 14 to 16 hours after PTCA] and analyzed the dependence of the FSCT on the heparin anticoagulation level (aPTT) and the incidence of vagal reactions and puncture site complications. FSCT was significantly longer in group A (69+/-27 minutes versus 45+/-15 minutes; p<0.001) with high heparin anticoagulation level (aPTT, 88+/-46 seconds) in comparison to group B with low heparinization (aPTT, 59+/-34 seconds). Vagal reactions occurred more frequently in group A (15.3% versus 10.0%; p<0.01) and the incidence of minor hemorrhage at the arterial puncture site was also increased (9.5% versus 3.1%; p<0.05). In the clinical setting of intensive heparin anticoagulation and early sheath removal after PTCA (<8 hours), the FemoStop system cannot be recommended due to prolonged femoral artery compression times.
