Transradial vs Transfemoral Group-Randomized Efficacy and Safety Trial for Cerebral Angiography
Sponsor: Gansu Provincial Maternal and Child Health Care Hospital
Summary
This study will compare the efficacy and safety of the transradial approach versus the transfemoral approach for performing full cerebral angiography. Participants will undergo cerebral angiography via one of the two approaches and will be followed up during and after the procedure. The primary endpoint of this study is to evaluate the success rate of completing full cerebral angiography (including superselective catheterization of bilateral common carotid arteries, subclavian arteries near the vertebral artery origin, and the aortic arch) via the transradial approach versus the transfemoral approach. During the study, the medical team will also document procedural details, incidence of complications, patient comfort, and related costs to comprehensively evaluate the clinical performance differences between the two approaches.

Cerebral Angiography via the Transfemoral Approach
Following successful radial artery puncture, a 5F radial sheath was inserted. After sheath placement, an intra-arterial cocktail was administered via the sheath, consisting of nitroglycerin 200 μg, verapamil 2.5 mg, and a heparinized saline flush (30-40 U/kg). Standard full cerebral angiography was then performed. Upon completion of the procedure, hemostasis was achieved using a dedicated radial artery compression device. The pressure was gradually released and completely removed 3-6 hours postoperatively.
