Objective To investigate the safety and feasibility of performing neurointerventional diagnosis and treatment via left distal transradial access(dTRA)or via left transradial access(TRA).Methods The clinical data of patients,who received selective cerebral angiography or neurointerventional treatment using right/left dTRA/TRA at the Fudan Zhongshan Xiamen Branch Hospital of China between January 2022 and December 2023,were retrospectively analyzed.The clinical data including the basic information(including age,gender,diseases,etc.)and the clinical records(including operation mode,operative approach,X-ray fluoroscopy time,puncture-related complications,etc.)were collected.Results A total of 32 patients,who underwent neurointerventional treatment by using left dTRA/TRA approach(left-side group),were enrolled in this study.Among them 11 patients received selective cerebral angiography and 21 patients(having left-sided vertebrobasilar artery disease)received neurointerventional treatment.Other 49 patients,who underwent neurointerventional treatment by using right dTRA/TRA approach(right-side group)during the same period were also included in this study.Among them 19 patients received selective cerebral angiography and 30 patients(having right-sided vertebrobasilar artery disease)received neurointerventional treatment.Angiography reexamination was performed in the patients who had previously received treatment and all of them suffered from endovascular diseases of the anterior circulation system.All angiography and neurointerventional procedures were successfully accomplished with no occurrence of serious complications.In left-side group,4 patients changed to adopt TRA approach to complete the neurointerventional treatment,2 patients changed to adopt TFA approach to complete the neurointerventional treatment,and one patient changed to adopt TFA approach to complete the procedure due to vascular tortuosity of left dTRA.In patients receiving angiography,4 patients changed to adopt left TRA approach and 3 patients failed to complete the elective right subclavian artery catheterization.In patients receiving neurointerventional treatment,2 patients developed postoperative local bruising at the distal radial artery puncture point.Postoperative color ultrasound reexamination showed that there was no radial artery occlusion in all patients receiving angiography or neurointerventional treatment.In right-side group,among the patients receiving neurointerventional treatment,4 patients changed to adopt right TRA approach and 2 patients changed to adopt right TFA;among the patients receiving angiography,4 patients changed to adopt right TRA approach,and bilateral common carotid arteries and bilateral subclavian arteries catheterization were successfully accomplished in all patients;3 patients developed postoperative local bruising at the distal radial artery puncture point.Postoperative color ultrasound reexamination showed that there was no radial artery occlusion in all patients receiving angiography or neurointerventional treatment.No statistically significant differences in the success rate of distal radial artery puncture,intraoperative X-ray fluoroscopy time,catheterization success rate of 4 main vessels(including right common carotid artery,left common carotid artery,right subclavian artery and left subclavian artery),and incidence of postoperative puncture point complications existed between the two groups(all P＞0.05).Conclusion It is clinically safe and feasible to adopt left dTRA/TRA approach for performing selective cerebral angiography and neurointerventional treatment.
