ABSTRACTIntroductionTransradial angiography (TRA) has received considerable attention in the field of neurointervention owing to its advantages over transfemoral approaches. However, the difficulty of left internal carotid artery (ICA) catheterization under certain anatomical conditions of the aortic arch and its branches is a limitation of TRA. This study aimed to investigate the anatomical predictors of successful catheterization of the left ICA in TRA.Materials and MethodsFrom January 2020 to October 2020, 640 patients underwent TRA at a single institute. Among them, 263 consecutive patients who were evaluated by contrast-enhanced MRI before TRA were included in our study and assigned to success and failure groups, according to whether left ICA catheterization was possible or not. Anatomical predictors that may affect the success of left ICA catheterization in TRA were investigated for the purposes of our study.ResultsThe multivariable analysis included variables that demonstrated significant univariate associations with ICA catherization (P<0.0001). Variables included in the model were the type of aortic arch, height of right subclavian artery, turn-off angle of the left common carotid artery (CCA), distance between innominate artery to the left CCA, angulation of right subclavian artery, and angulation of the left CCA, which we identified as significant predictors of left ICA catheterization.ConclusionSuccess of left ICA catheterization in TRA was related to the vascular geometry of the aortic arch and its branches. Evaluating the anatomical predictors identified in this study using pre-procedure imaging may enhance the success rate of left ICA catheterization in TRA.

The Vertebral Artery (VA) is classically described as originating as the first branch of the ipsilateral subclavian artery. The VA origin is variable and has been identified at the aortic arch, Common Carotid Artery (CCA), and Internal Carotid Artery. The VA arising from the carotid artery is an extremely uncommon variant. Left VA origin from the left CCA has been reported only thrice. These rare anomalous origins of the VA usually are asymptomatic. We describe symptomatic aberrant origin of left vertebral artery from left common carotid artery, a rare case.

We present a case of unilateral internal carotid artery (ICA) agenesis with trans-sellar anastomosis associated with a right aortic arch, and discuss the embryonic development and clinical implications of this condition. A 26-year-old woman without significant medical history was referred to our hospital complaining of tinnitus. She denied any other symptoms, and examination did not reveal any other neurological deficits. Radiological examinations showed agenesis of the right ICA with trans-sellar anastomosis, and a right aortic arch. This vascular configuration reflects the anatomical homology with avian vascular structure. Recognition of this anomaly has important implications for clinical situations, such as the planning of carotid or transsphenoidal surgery, the management of thromboembolic disease, and the surveillance and detection of associated cerebral aneurysms.
