Abstract
BACKGROUND: Cerebral angiography, or intra-arterial digital subtraction angiography (DSA), is a fluoroscopic imaging technique. In China, until recently, transfemoral access (TFA) has been used, rather than transradial access (TRA). This retrospective study aimed to compare transfemoral cerebral angiography (TFCA) with transradial cerebral angiography (TRCA) consecutively performed by the same operator, at a single center in China, to determine whether there were benefits from the shift from TFA to TRA in terms of efficiency, safety, and feasibility.
MATERIAL AND METHODS: A review of 1,048 cerebral angiograms in 980 patients was performed by a single operator from June 2014 to May 2018, including the TFA group (n=513) and the transradial access (TRA) group (n=535), and 39 patients underwent both TFA and TRA. The total procedure time, duration of fluoroscopy, catheterization success rate, image quality, length of stay in hospital, complications of the procedure, and patient preference were compared between the groups.
RESULTS: Compared with TFCA, TRCA resulted in significantly shorter total procedure time, a higher catheterization success rate, better image quality, and shorter duration of hospital stay (P<0.05). There was no significant difference between the TFA and TRA groups for cardiovascular, cerebral, and access site complications. Patients in the TRA group showed a significantly reduced fluoroscopy time at the early stages of operator training (P<0.05). Patient preference included TRA (76.74%), TFA (16.28%), and no preference (6.89%).
CONCLUSIONS: During four years at a single center, and with a single operator, TRCA was safe, feasible, and more rapid when compared with TFCA.
