Application of transradial artery approach in cerebral angiography

Abstract

Objective To explore the application of transradial artery (TRA) approach in cerebral angiography. Methods A total of 300 patients, at Department of Neurosurgery of Wenzhou Central Hospital from September 2015 to May 2016, underwent cerebral angiography and were divided into TRA group (n=152) and transfemoral artery (TFA) group (n=148). The complication rates and image quality scores were compared between the groups. Results In both groups, 1 patient suffered from cerebral infarction within 3 days. Two patients suffered from transient ischemic attach (TIA) in TRA group and 3 in TFA. No patient reported myocardial infarction in either group. There was no significant difference between the 2 groups (P>0.05). In TRA group, 5 patients had hematoma at the access site and 17 in TFA. One patient reported vessel dissection in TRA group and 10 in TFA. The occurrence rates of hematoma at the access site and vessel dissection in TRA group were significantly lower than those in TFA (P 0.05). The mean score of the image quality of all 4 arteries was 11.58±0.90 in TRA group and 11.71±1.10 in TFA group. There was no significant difference between the 2 groups (P>0.05). The mean score of each artery was as follows: RCCA (2.96±0.23 in TRA; 2.94±0.35 in TFA), LCCA (2.93±0.30 in TRA; 2.97±0.16 in TFA), RVA (2.92±0.29 in TRA; 2.82±0.53 in TFA) and LVA (2.76±0.62 in TRA; 2.97±0.16 in TFA). The overall scores of all four arteries and the subscores of RCCA, LCCA and RVA had no significant difference between the 2 groups (P>0.05). The subscore of RVA of type Ⅲ aortic patients in TRA group was significantly higher than that in TFA group (P<0.05). Conclusions The image quality of TRA is comparable to that of TFA with low rate of hematoma at the access site and more comforts of the patient. Selective RCCA and RVA angiography may be more efficient in Type Ⅲ aortic arch via TRA. Key words: Cerebral angiography; Radial artery; Femoral artery; Prospective studies
