ABSTRACT
The purpose of this study is to describe a single operator's experience with the feasibility and safety of transradial access in conventional cerebral angiography. 153 patients were enrolled consecutively. Among them, 20 patients were not suitable for transradial access. A Simmons catheter was used. Haemostasis was achieved using a compressive dressing of the wrist. We analysed the success rates of the arterial puncture and the successful catheterization rate for each supra-aortic vessel as well as all complications. The arterial access was successful in 96.3%. The supra-aortic vessels were catheterized with success rates of 99.2% (127/128) for the left subclavian artery and 100% for the other arteries. The mean procedure time was 19.3 min (range 10-55 min). Haemostasis was successfully achieved in every case. The most frequent complication was arm pain which occurred in 37 patients (28.9%). In conclusion, transradial selective cerebral angiography with a reversed-angle catheter is technically feasible and safe. It might be helpful in imaging follow-up of patients with arterial stenting or coil embolisation of the cerebral aneurysms. Modification of the catheter design is required to improve the selectivity of the supra-aortic branches.
