Surgical correction and SPECT imaging of vertebrobasilar insufficiency due to unilateral vertebral artery stenosis.
BACKGROUND AND PURPOSE Incapacitating vertebrobasilar insufficiency is generally associated with bilateral vertebral artery disease, whereas unilateral vertebral artery stenosis usually is clinically silent. Regional brain perfusion has not been part of the routine evaluation of patients with vertebrobasilar insufficiency. This report describes two patients who had isolated unilateral vertebral...
متن کاملPersistent Marked Peripheral Eosinophilia due to Tuberculosis: A Case Report
We report a case of a 68-year-old female who was a known case of diabetes mellitus and chronic liver disease and presented with complaints of dry cough and other constitutional symptoms since one month. During initial investigations, the patient was found to have peripheral blood eosinophilia. Upon investigating further,the patient was found to have mediastinal lymphadenopathy and fine-needle a...
متن کاملRotational vertebrobasilar ischemia due to vertebral artery dynamic stenoses complicated by an ostial atherosclerotic stenosis.
We describe a patient with rotational vertebrobasilar ischemia (RVBI) due to vertebral artery (VA) compressive stenoses during neck rotation, complicated by an ostial atherosclerotic stenosis (OAS). Referred for 'near-syncopal spells', inquiry revealed a symptom-complex consistent with vertebrobasilar transient ischemic attacks (TIAs) provoked by head rotation. VA dynamic angiography with imagi...
متن کاملExternal carotid-vertebral artery anastomosis for vertebrobasilar insufficiency.
Two patients with previous brain stem infarction and current symptoms of vascular insufficiency in the basilar circulation had evidence of vertebral artery occlusive disease. Angiography demonstrated ostial stenosis of the dominant right vertebral artery and retrograde flow down the left vertebral artery to the level of the transverse process of C2 in the first case and to the level of a severe...
متن کاملRotational 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...
