Right internal carotid artery stenosis leads to all except :
Ans: D (Drop attacks) Ref: Harrison's Principles of Internal Medicine. 18th ednExplanation:Proximal MCA occlusion leads to:o Contralateral hemiplegiao Hemianesthesiao Homonymous hemianopiao Gaze preference to the ipsilateral side.Dysarthria, when the dominant hemisphere is involved, global aphasia is present, and when the nondominant hemisphere is affected, anosognosia. constructional apraxia, and neglect are found.The clinical picture of internal carotid occlusion varies.When the origins of both the ACA and MCA are occluded at the top of the carotid artery, abuiia or stupor occurs with hemiplegia, hemianesthesia, and aphasia or anosognosia.When the PCA arises from the internal carotid artery fa configuration called a fetal posterior cerebral artery), it may also become occluded and give rise to symptoms referable to its peripheral territory.Internal carotid disease causes recurrent transient monocular blindness (amaurosis fugax).A high-pitched prolonged carotid bruit fading into diastole is often associated with tightly stenotic lesions.All symptoms and signs of internal carotid occlusion may also be present with occlusion of the common carotid artery. Jaw claudication may result from low flow in the external carotid branches.Vertebrobasilar Ischemic attacks are characterized by vertigo, ataxia, diplopia, dysarthria, dimness or blurring of vision, perioral numbness and paresthesias, and weakness or sensory complaints on one, both, or alternating sides of the body.Also Note:Drop attacks due to bilateral leg weakness, without headache or loss of consciousness, may occur, sometimes in relation to head movements.
