The study aims to understand the success rate and the complications of using DR (distal radial) artery access and proximal radial artery (PR) access for treating superficial femoral artery intervention.

The researchers collected data from 2006 to 2019 and compiled 195 patients with SFA stenosis treated with either DR or PR access. Whenever needed, secondary access through pedal artery was given. The main outcomes studied were procedure time, treatment success, radiation dose, fluoroscopy time, and crossover ratio.

The procedure was a success in 96.4% of the subjects. Dual access was required in 36.8% of patients in DR and 18.9% of patients in the PR group. Chronic occlusion was found in 96.1% of DR and 92.6% of PR patients. 39.4% of DR and 24.8% of PR patients had stent implantation. There was no significant difference between the groups in procedure time, radiation dose, contrast volume, and fluoroscopy time. The rate of access was also similar in both groups.

The SFA intervention through PR and DR access is safe and efficient. Both methods have a high success rate and acceptable morbidity. However, the DR process has a few site complications.
