Distal radial artery access in the anatomical snuffbox for coronary angiography and intervention

Abstract

BACKGROUND:

To explore the feasibility and safety of coronary angiography (CAG) and percutaneous coronary intervention (PCI) via the distal radial artery in the anatomical snuffbox.

METHODS:

Ninety two patients who underwent CAG or PCI through distal radial artery access at The Second Affiliated Hospital of Zhejiang Chinese Medical University from September 2017 to March 2018 were included in our study. We collected baseline characteristics, number, and duration of arterial punctures, procedural success rate, postoperative compression time, the numerical rating scale (NRS) scores at 3 hours after procedure, complications, hospitalization duration.

RESULTS:

The mean age was 69 ± 11years (44–92 years), and there were 57 males (62.0%). The diameter of the right distal radial artery and the more proximal right radial artery were 0.171 ± 0.05 cm, 0.213 ± 0.06 cm, respectively. On average, the number of puncture attempts was 1.52 ± 0.81, access time was 2.3 ± 1.78 minutes (0.33 – 8.72 minutes), access success was 95.7%, the postoperative compression time was 3.41 ± 0.76 hours (2–6 hours), the NRS scores at 3 hours was 1.53 ± 0.72 (1–4), and the mean hospitalization duration was 7.13 ± 4.02 days. Four patients underwent left distal radial artery access and 88 patients underwent right distal radial artery access. There were 3 local hematomas after procedure and 2 patients had vasospasm. There were no cases of major bleeding, arteriovenous fistula, radial artery occlusion, or hand numbness.

CONCLUSIONS:

Cardiac catheterization through the distal radial artery in the snuffbox is safe and feasible. The right distal radial artery access can be routinely carried out.
