Background: Distal transradial access (dTRA), through the anatomical snuffbox (AS) of the hand, is a novel, potentially beneficial, vascular access for patients undergoing coronary procedures. Method: Consecutive patients with an indication for coronary angiography and/or percutaneous coronary intervention (PCI) were enrolled in our tertiary center, from November 2018 to March 2019. The success rate of the procedure, the incidence of local complications, the time required for hemostasis, and the incidence of radial artery occlusion (RAO) were evaluated. Results: Α total of 167 patients were catheterized through the dTRA (79.6% men, 20.4% women), with a median age of 64 years. The indication for catheterization was ACS in 80 (47.9%) patients, stable coronary artery disease in 51 (30.5%) patients, and other reasons in 36 (21.6%) patients. Fifty patients (32.9%) underwent PCI. Successful sheath insertion was recorded in 152 (91.0%) patients. The mean time to hemostasis after sheath removal was 52 ± 11 min. Vascular access site complications were evaluated with ultrasound in 62 (40.8%) of the enrolled patients, 40 ± 15 days after the procedure. Among them, 2 (3.2%) patients presented with arteriovenous fistula, and 2 (3.2%) patients with local occlusion at the puncture site within the AS and distal to the transverse ligament, with preservation of the patency of the radial artery proximal to the radial styloid process. Conclusion: The dTRA may be a feasible and safe access site for diagnostic and interventional coronary procedures, with decreased incidence of RAO and time required for hemostasis compared to classical radial artery access. |
