Purpose:

There is an increased adoption of Radial access (RA) by the Interventional Radiology (IR) community. Several studies have shown that patients prefer RA vs femoral access and that it is an effective and safe access in embolotherapy. This is the largest IR observational study in RAVI with 12 months follow up of real clinical practice outcomes.

Materials and Methods: Prospective study included embolizations of uterine fibroids (UF), benign prostatic hyperplasia (BPH), liver tumors (LT), and other hypervascular tumors (OHT) performed in 5 US hospitals with a 12 months follow-up. The primary safety endpoints included RA-related complications, stroke and death at 30 days and 12 months. The procedural endpoint was defined as successful completion of the intended procedure using RA. Technical success was defined as the successful embolization of the target lesion/organ.

Results: Between February 2020 and January 2022, 99 patients were treated. 70 (70.7%) had UF, 16 (16.2%) BPH, 7 (7.1%) LT and 6 (6.1%) OHT. The mean age was 50.1 (±11.1) years and 74/99 (74.7%) were females. Technical success was 100%. There was 0% of stroke and hand ischemia at 30 days. 12 months follow-up (FU) will be completed within the next 2 months and the data will be presented at the meeting.

Conclusion: This prospective registry confirmed the safety and efficacy of radial access at 30 days FU in RAVI. There was no stroke, hand ischemia or procedure related death, and low rates of minor RA-related complications. 12 months data will be presented at the meeting.
