“…There were 43 (4.5%) patients with cerebrovascular lesions, including cerebral infarcts [ 9 - 24 ] in 17 (39.5%), cerebral vascular aneurysms without cerebral hemorrhage [ 14 , 23 , 25 , 26 ] in 4 (9.3%) and cerebral hemorrhage in 18 (41.9%), and ischemic cerebrovascular disease [ 25 ] , transient ischemic attack [ 14 ] , partial thrombus detected in the left internal jugular vein and sigmoid sinus [ 27 ] , and vertebrobasilar insufficiency [ 28 ] in 1 (2.3%) patient each. The 18 cerebral hemorrhages were subarachnoid hemorrhage in 14 (77.8%) [ 29 - 39 ] (8 were associated with an aneurysm of the cerebral artery [ 29 - 31 , 33 , 35 - 37 , 39 ] ), intraventricular hemorrhage in 2 (11.1%) [ 40 , 41 ] and intracerebral hemorrhage [ 42 ] and subarachnoid and intraventricular hemorrhages [ 43 ] in 1 (5.6%) patient each.…”

Aberrant origin of vertebral artery is rare. The anatomical features and clinical significance of this lesion remain to be clarified. A comprehensive collection of the pertinent literature resulted in a cohort of 1286 cases involving 955 patients and 331 cadavers. There were more left than right and more unilateral than bilateral aberrant vertebral arteries. Patients with aberrant origin of vertebral artery were often asymptomatic and in only 5.5% of the patients their symptoms were probably related to the aberrant origin of vertebral artery. The acquired cardiovascular lesions were present in 9.5% of the patients, 20.9% of which were vertebral artery-associated lesions. Eight (0.8%) patients had a vertebral artery dissection. Logistic regression analysis showed significant regressions between bovine trunk and left vertebral artery (P=0.000), between the dual origins of vertebral artery and cerebral infarct/thrombus (P=0.041), between associated alternative congenital vascular variants and cervical/aortic dissection/atherosclerosis (P=0.008). Multiple logistic regression demonstrated that side of the aberrant origin of vertebral artery (left vertebral artery) (P=0.014), arch branch pattern (direct arch origin) (P=0.019), presence of the common trunk (P=0.019), associated acquired vascular disorder (P=0.034) and the patients who warranted management (P=0.000) were significant risk predictors for neurological sequelea. The patients with neurological symptoms and those for neck and chest operations/ interventions should be carefully screened for the possibility of an aberrant origin of vertebral artery. The results from the cadaver metrology study are very helpful in the design of the aortic stent. The arch branch pattern has to be taken into consideration before any maneuver in the local region so as to avoid unexpected events in relation to aberrant vertebral artery.

“…In their own unbiased study they found the prevalence of intracranial aneurysms in patients with pTA to be not greater than in the general population [29]. Another vascular anomaly, concerning a vertebral artery ending in pICA, has been described in association with moyamoya disease [30]. Bilateral pTA, even a very rare anatomic finding, was also shown to be associated to intracranial aneurysms [4,5].…”
