Ultrasound-Guided Axillary Access Using a Micropuncture Needle Versus Conventional Cephalic Venous Access for...

(1) Background: Ultrasound-guided axillary (USAX) vein puncture is a relatively new method to obtain venous access for the implantation of cardiac implantable electronic devices (CIED). However, its use is limited as most of the operators are not familiar with this technique. Our aim was to investigate the safety and efficacy of the USAX compared with the traditional cephalic vein dissection for venous access in CIED implantation. (2) Methods: This was a single-center, randomized, controlled, superiority trial. A total of 114 patients were randomized (1:1 ratio) to either USAX (u/s axillary group; 59 patients) or cephalic vein access (cephalic group; 55 patients). The primary study endpoint was defined as successful placement of all leads via the chosen access. Secondary study endpoints included time from local anesthetic injection to lead advancement in the SVC, total procedure time (skin to skin), procedure-related complications and pain perception. (3) Results: USAX was superior to cephalic access in terms of primary endpoint (OR: 4.3, 95% CI: 1.3, 14.0; p = 0.012). Total procedure duration was higher in the cephalic group (55.15 ± 16.62 vs. 48.35 ± 12.81 min, p = 0.017) but there was neither a significant difference in fluoroscopy time (p = 0.872) nor in total radiation dose (p = 0.815). The level of pain was higher in the cephalic group (p = 0.016), while the rates of complications were similar in both groups (p > 0.05). (4) Conclusion: USAX was superior to cephalic access regarding success rate, total procedure duration and level of pain, while having no difference in complication rates.
