Carotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion
Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
متن کاملIntermittent occlusion of internal carotid artery by hypoglossal nerve.
A 51-year-old man experienced the onset of positionally dependent neurologic changes . When he turned his head to the left and extended his neck for longer than 3 sec he became dizzy and experienced a sensation of "numbness" over his right body, including his face. This was accompanied by loss of motor control of the right body. He had some blurring of vision during these episodes but no loss o...
متن کاملA case of Horner syndrome with intermittent mydriasis in a patient with hypoplasia of the internal carotid artery.
We report a rare case of hypoplasia of the right internal carotid artery (ICA) with ipsilateral congenital Horner syndrome. The etiology and pathogenesis of hypoplasia of the ICA is not well understood. Multiple types of collateral flow have been reported to develop to maintain blood supply to the ipsilateral cerebral hemisphere. Although collateral flow may allow these patients to remain asymp...
متن کاملLupus anticoagulant associated with extracranial internal carotid artery occlusion.
To the Editor Some cases of lacunar infarction with middle cerebral artery (MCA) stenosis may be explained by the Bernoulli principle. In a constant flow system, the smaller the cross-sectional area, the greater the flow velocity, and the lower the perfusion pressure. If the flow were turbulent, the pressure would be lower still. Thus, if the origin of a lenticulostriate artery were within a st...
