Investigating optimal compression approach following radial artery puncture: a retrospective study

The method for compressing hemorrhagic sites after transradial access has been a topic of interest, yet definitive guidelines remain elusive. This study aims to address this gap by optimizing the mechanical compression hemostasis protocol after transradial access.

This retrospective analysis included 300 patients from the Department of Cerebrovascular Diseases, Shanghai Fourth People's Hospital affiliated to Tongji University, who underwent transradial access for cerebrovascular angiography. Following the procedure, patients received radial artery compression hemostasis using a balloon compressor. They were divided into group A (n=100, continuous deflation) and group B (n=200, intermittent deflation) according to different hemostasis methods. The incidence of bleeding at the puncture site and complications were compared between the two groups.

The rate of bleeding at the puncture site was significantly lower in group B (20 out of 200 patients) compared to group A (20 out of 100 patients) (P=0.032). Similarly, the incidence of puncture site complications, such as edema, congestion, and wound infection was lower in group B (5 out of 200 patients) compared to group A (10 out of 100 patients) (P=0.006).

Four hours of compression with intermittent deflation (group B) emerged as the optimal compression method after transradial access, demonstrating fewer complications at the patient's puncture site.
