Title:
Comparison of Arterial and Venous Blood Flow Between Patients with Pressure Dressing or a New Hemostatic Puncture Closure Device After Cardiac Catheterization
Description:
<jats:p>The aim of the study was to compare arterial and venous flow volume in the punctured leg in patients given a conventional pressure dressing and those given a new hemostatic puncture closure device (Angio‐Seal) after cardiac catheterization. We prospectively measured blood flow in 25 patients with pressure dressing (group A) and 25 patients with Angio‐Seal (group B) after cardiac catheterization. Duplex sonographic measurements were performed at the superficial femoral artery and vein of the punctured leg. In group A measurements were performed before catheterization, during pressure dressing, and after removal of pressure dressing. In group B we performed the measurements before catheterization and after closure of the puncture site with Angio‐Seal. Mean arterial and venous blood flow of the superficial femoral artery and vein were calculated. Statistical evaluation was performed using the one‐sample Wilcoxon test. In group A there was a significant reduction of blood flow volume in both the femoral artery, from a mean of 119 mL/min before puncture to 78 mL/min with pressure dressing, and the femoral vein, from 114 mL/min before puncture to 82 mL/min with pressure dressing (P < 0.0001). After removal of pressure dressing the blood flow rose to 119 mL/min in the femoral artery and 116 mL/min in the femoral vein. In group B there was no change in flow volume before and after catheterization (femoral artery: 117 vs 118 mL/min, femoral vein 119 vs 120 mL/min, P = ns). We conclude that the use of pressure dressing after cardiac catheterization caused a significant reduction in arterial and venous blood flow (about 30%) during immobilization. The new Angio‐Seal closure device did not affect arterial or venous flow.</jats:p>
