Manual compression hemostasis using a hemostatic pad for the distal radial artery approach

The method of hemostasis for the distal radial approach has not been standardized, although this approach has become increasingly popular due to its advantages. In this study, we investigated the feasibility of manual compression hemostasis using a calcium alginate pad after coronary angiography via the distal radial approach.

We retrospectively collected 150 consecutive patients (mean age, 74.9 ± 8.0 years; male, 75 %) who underwent coronary angiography via the distal radial artery with a predominantly 4 Fr sheath from April 2021 to December 2022 and were hemostatic according to the following methods. After sheath removal, hemostasis was achieved by manual compression for 10 min using a hemostatic pad containing calcium alginate. When hemostasis was confirmed, a small log-shaped gauze was placed over the pad and fixed using a self-adhesive elastic bandage for 2 h. All procedures were performed by four fellows just beginning the distal radial approach.

The mean compression time was 12.4 ± 4.8 min, and hemostasis was successfully achieved in all patients, allowing the release of the elastic bandage after 2 h, with only one patient oozing the next morning. There were no major complications, while one patient had a >10 cm hematoma. Compared to that of the first 15 patients, for each fellow, the compression time of the subsequent patients was significantly shorter (14.5 ± 6.7 vs 11.1 ± 2.1 min, p < 0.01).

Manual compression hemostasis using calcium alginate pads for the distal radial artery approach appears feasible with a simple learning.
