• The aim of this study is to determine, via retrospective study, the effects of vascular morphology and related factors on the success of selective arterial catheterization of the left vertebral artery when approached via right-sided radial artery cerebral angiography. Patients who had undergone diagnostic cerebral angiography were enrolled, and their medical history, catheter type, and vessel morphology were analyzed. A total of 205 patients were enrolled in this study from February 2014 to December 2015. After exclusion according to defined criteria, 161 patients were incorporated into the final analysis. Selective catheterization of the bilateral subclavian artery and the bilateral common carotid artery were conducted successfully in all patients, and the success rate of selective catheterization of the left vertebral artery was 82.0%. The success rate of the left vertebral artery catheterization was positively correlated with the angle between the left vertebral artery and the left subclavicular artery (P < 0.001), with 90° serving as a demarcation point, and this was higher in patients without innominate artery distortion (90.2–75.0%), although this finding was not statistically significant. However, the morphology of the aortic artery did not affect the success rate of selective catheterization of the left vertebral artery (P = 0.189), and there was no significant difference (P = 0.231) in the success rate of selective catheterization if the left vertebral artery was predominant (91.0%, 81/89) or balanced (84.7%, 61/72). A total of 0.9% (2/161) of the patients experienced surgery-related complications. Both these patients exhibited bleeding at the puncture point when they were deflated 2 hr after the operation. They were pressurized and depressurization was again conducted for an appropriate period of time. The angle between the left vertebral artery and the left subclavicular artery is the primary vessel-associated morphological factor affecting the success rate of selective catheterization of the left vertebral artery in the right-sided radial artery cerebral angiography, while innominate artery distortion also had some more limited impact on this success rate.
