E-241 Robotic spinal angiography: insights from a single-center study

Le résumé fourni par la source

Introduction Robotic neurointervention offers enhanced procedural precision, reduce radiation risk, and improve access to care. Originally designed for interventional cardiology, the CorPath GRX platform is now being studied in neurointervention. Several recent studies have explored the benefits of robotic cerebral angiography, there is limited information on its use for spinal angiography. This series aims to evaluate our experience with the CorPath GRX in spinal angiographic procedures, filling a critical gap in neurointerventional research. Methods In this single-center retrospective case series, we analyzed 11 patients who underwent robotic-assisted diagnostic procedures with the CorPath GRX system from February 3, 2022 to March 6, 2023 at our institution. A descriptive synthesis was performed on the demographic, baseline, surgical, and postoperative data collected. Results The average age of the 11 patients included was 54 ± 20.34 years, 6 (54.55%) of them being female. Mean BMI was 29.58 ± 7.86 and 7 (63.64%) were non-smokers. A total of 11 procedures were performed utilizing the CorPath GRX system, 4 (36.36%) were partially converted to manual technique. General anesthesia was administered in 9 cases (81.82%) and the right-side femoral access was used in 10 (90.91%) patients. Mean fluoroscopy time was 24.81 ± 10.19 min, mean contrast dose was 174.09 ± 57.31 mL, mean DAP was 472.23 ± 437.57Gy cm², and mean air kerma was 2438.84 ± 2107.06 mGy. No robot-related complications were reported, and procedure-related complications were minimal. Conclusions The CorPath GRX system, a robotic-assisted platform, has proven reliable and safe in spinal angiography, evidenced by its enhanced procedural accuracy and reduced radiation exposure for operators. Its advanced technology and efficiency advocate for its increased adoption in clinical settings, potentially improving patient outcomes and revolutionizing standard angiographic practices.
