Rotational Vertebral Artery Compression : Bow Hunter's Syndrome
Bow hunter's syndrome (BHS) is rare cause of vertebrobasilar insufficiency that arises from mechanical compression of the vertebral artery by head rotation. There is no standardized diagnostic regimen or treatment of BHS. Recently, we experienced 2 cases resisted continues medication and treated by surgical approach. In both cases, there were no complications after surgery and there were improv...
متن کاملVertebral artery compression of the medulla.
BACKGROUND Intracranial arteries in the subarachnoid space may compress the brain parenchyma and cranial nerves. Most arterial compressive lesions have been attributed to dolichoectasia in the vertebral-basilar system, and prior reports have concentrated on the pressure effects of basilar artery ectasia. Much less is known about vertebral artery compression of the medulla. OBJECTIVE To descri...
متن کاملAnatomical Variations of Vertebral Artery
Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...
متن کاملMechanical compression of the extracranial vertebral artery during neck rotation.
Using duplex ultrasonography (US), the authors showed compression of the extracranial vertebral artery (ECVA) during neck rotation in 5.0% of 1,108 patients. Age (per 10-year increase, OR 0.80, 95% CI 0.67 to 0.96), vessel diameters (per 0.5-mm diameter increase, OR 0.63, 95% CI 0.51 to 0.79), and symptoms upon neck rotation (OR 4.01, 95% CI 1.35 to 11.9) were associated with vessel compression...
متن کاملProvokable bilateral vertebral artery compression diagnosed with transcranial Doppler.
BACKGROUND Head and neck movements may cause vascular compression that produces a syndrome of vertebrobasilar insufficiency. Vertebrobasilar circulation was examined noninvasively in two patients who were able to provoke these symptoms repeatedly on demand. CASE DESCRIPTIONS Blood flow velocities in the basilar artery (case 1) and both posterior cerebral arteries (both cases) were measured co...
