A modified technique for aortic arch and cerebral angiography using one Simmons II catheter

Résumé fourni par la source

Background Radial access is an increasingly popular approach to neuroradiology. Typically, aortic arch and cerebral angiography are performed using a 5F pigtail catheter and a 5F Simmons II catheter. This classical operation increases the operation time, radiation time, and radiation dose, and the catheters pass through the radial artery multiple times, thereby increasing the risk of radial artery spasms and occlusions. In this study, we aimed to demonstrate that using a Simmons II catheter to complete the aortic arch and cerebral angiography is safe and effective. Methods This study was a retrospective review of the database on aortic arch and cerebral angiography procedures using two catheters (pigtail catheter and Simmons II catheter) or one catheter (Simmons II catheter) to perform aortic arch and cerebral angiography between August 2024 and January 2025. Patient demographics, clinical data, procedural metrics and radiographic metrics were recorded. Sixty patients underwent aortic arch and cerebral angiographies. Thirty patients underwent aortic arch and cerebral angiographies with two catheters and thirty with one catheter. Results Total procedure and fluoroscopy times were shorter in the one catheter group. The contrast volume, dose-area product and total radiation dose were lower in the one-catheter group. Clinical outcomes between the two groups showed no statistically significant differences. Conclusions We confirmed for the first time that using a Simmons II catheter to complete the aortic arch and cerebral angiography was effective and safe.
