Transradial approach for diagnostic cerebral angiograms in the elderly: a comparative observational study


Background The transradial approach (TRA) reduces mortality, morbidity, access site complications, hospital cost, and length of stay while maximizing patient satisfaction. We aimed to assess the technical success and safety of TRA for elderly patients (aged ≥75 years).

Methods A retrospective chart review and comparative analysis was performed for elderly patients undergoing a diagnostic cerebral angiogram performed via TRA versus transfemoral approach (TFA). Also, a second comparative analysis was performed among the TRA cohort between elderly patients and their younger counterparts.

Results Comparative analysis in the elderly (TRA vs TFA) showed no significant differences for contrast dose per vessel (43.7 vs 34.6 mL, P=0.106), fluoroscopy time per vessel (5.7 vs 5.2 min, P=0.849), procedure duration (59.8 vs 65.2 min, P=0.057), conversion rate (5.8% vs 2.9%, P=0.650), and access site complications (2.3% vs 2.9%, P=1.00). Radiation exposure per vessel (18.9 vs 51.9 Gy cm2, P=0.001) was significantly lower in the elderly TRA group.

The second comparison (TRA in elderly vs TRA in the young) showed no significant differences for contrast dose per vessel (43.7 vs 37.8 mL, P=0.185), radiation exposure per vessel (18.9 vs 16.5 Gy cm2, P=0.507), procedure duration (59.8 vs 58.3 min, P=0.788), access site complication (2.3% vs 1.7%, P=0.55), and conversation rate (5.8% vs 1.8%, P=0.092). A trend for prolonged fluoroscopy time per vessel (5.7 vs 4.7 min, P=0.050) was observed in the elderly TRA group.

Conclusions TRA is a technically feasible and safe option for diagnostic neurointerventional procedures in the elderly. Our small elderly cohort was not powered enough to show a significant difference in terms of access site complications between TRA and TFA.
