Use of a collagen plug versus manual compression for sealing arterial puncture site after cardiac catheterization

Abstract

The aim of the study was to investigate (1) the safety and efficacy of the application of a collagen plug (Vasoseal) at arterial puncture sites, (2) the hemostasis time, and (3) the comfort for the patient of a collagen plug (Vasoseal) when compared with manual compression. Sixty-two patients were randomized either for application of a collagen plug (Vasoseal, group A, n = 33) or manual compression (group B, n = 29) after cardiac catheterization. All patients were evaluated for subjective pain score ranging from 1 to 5 (1 = no pain up to 5 = very strong pain). In addition the authors measured the time until hemostasis could be achieved. The patients were evaluated by duplex sonography for complications at days 1 and 7 after the procedure. The pain score demonstrated a significantly lower score in group A when compared with group B (P = 0.01). The mean time for hemostasis was significantly lower in group A (mean 9.6 minutes) when compared with group B (mean 23.6 minutes) (P = 0.0001). Regarding the complication rate there was no significant difference between the groups (group A vs group B, P = 0.82). The authors conclude that the application of a collagen plug at the arterial puncture site is a safe and time-saving method. In addition it is less painful and therefore better tolerated than manual compression.
