Effects and safety of the transradial artery approach for cerebral angiography: A comparative observational study

Background

Conventionally,the transfemoral artery approach has been the primary approach for neurointervention. However, this approach has been associated with perioperative complications. Thus, the purpose of this study was to evaluate the safety and feasibility of the transradial artery approach in cerebral angiography.

Methods

This study collected 2504 patients who received cerebral angiography at our center from November 2017 to June 2021. There were 1105 patients in the transradial artery group and 1399 patients in the transfemoral artery group.

Results

There were 1088 successful cases in the transradial artery group and 1386 cases in the transfemoral artery group. However, there was no significant difference in the success rate and intraoperative radiographic exposure time between the two groups (P > 0.05). The length of hospital stay and perioperative complications were significantly less in the transradial artery group than in the transfemoral artery group (P < 0.05). The logistic regression analysis for risk factors shows that age (OR = 1.891, 95 % CI 0.057–3.382, P = 0.032) and hypertension (OR = 3.265, 95 % CI 1.003–10.627, P = 0.049) were independent risk factors for angiographic success in TRA group.

Conclusion

Compared to the transfemoral artery approach, the transradial artery approach was associated with shorter hospital stays, less perioperative complications and can be used as a available approach in cerebral angiography. Age and hypertension were independent risk factors for angiographic success in TRA group.
