Abstract:
Objective To investigate the role of continuous arterial pressure monitoring in discovering catheter kinking and knotting in cerebral angiography via transradial access.
Methods A retrospective analysis was performed in 116 patients with ischemic cerebrovascular disease who underwent cerebral angiography via transradial access between July 2017 and December 2019. Of them, 36 patients were completed using the traditional connecting catheter method, and 80 patients received cerebral angiography under continuous arterial pressure monitoring (pressure-monitoring group), other 36 patients were as non-pressure-monitoring group. It indicated that a certain segment of the catheter kinked or knotted when pressure difference of arterial pressure becomes smaller during the operation. The gender, age, aortic arch type, and other basic clinical and pathological information, and the surgical indications, fluoroscopy time, and operation time, and incidence of catheter kinking and knotting were compared in patients between the two groups.
Results There was no significant difference in gender, age, aortic arch type, fluoroscopy time, and operation time between the two groups. The incidence of catheter kinking and knotting in the pressure-monitoring group was significantly lower than that in the non-pressure-monitoring group (0 vs 8.33%, P=0.047).
Conclusions During cerebral angiography via transradial access, continuous artery pressure monitoring is helpful to discover catheter kinking and knotting, and reduces related complications rates, which is worthy of further promotion and application.
