Intracranial aneurysm in paediatric age group is rare and association of the aneurysm with congenital vertebral artery anomaly is further rarer. We describe such a case in an 11-year-old male patient who consulted a paediatrician about headache and vertigo, and a noncontrast CT (NCCT) head revealed peripherally calcified hyperdense mass in prepontine and basal cisterns. Magnetic resonance imagi...
Objective: Vertebral and basilar artery stenosis is one of the main reasons causing posterior circulation ischemia. In this study, we evaluated the effectiveness of Brain Electrical Activity Mapping (BEAM) and Transcranial Doppler (TCD) in assessing the functional improvement of the vertebral basilar artery stenosis after endovascular stenting. Methods: Forty patients with vertebral and basilar...
We present a case of an arch anomaly in a 54-year-old female who was admitted to our hospital for magnetic resonance angiography (MRA) to evaluate her right-sided numbness. MRA revealed a truncus bicaroticus, right common carotid artery (CCA) originating right vertebral artery, right subclavian artery arising as the final branch of the descending aortic arch and arch originating left vertebral ...
Blood flow in the vertebral artery and the upper extremity was studied in five cases of Takayasu's arteritis with subclavian steal by use of ultrasonic Doppler flowmetry and finger plethysmography. The diagnosis of subclavian steal was made by observation of flow reversal in the vertebral artery on the subclavian steal side during grip exercise and, in addition, the vertebral flow change with b...
Eight patients are described who developed infarctions in the vertebral-basilar artery distribution following chiropractic neck manipulation or spontaneous head turning. The angiographic and autopsy findings indicate that injury to the intima of the vertebral artery at the atlantoaxial joint forms a nidus for thrombus formation which may propogate or embolize to involve other vessels in the ver...
