8B11.51/I63.5 Cerebral ischaemic stroke due to unspecified occlusion or stenosis of intracranial large artery



Cerebral ischaemic stroke due to unspecified occlusion or stenosis of an intracranial large artery is caused by a narrowing or blockage of an artery in the brain. This can be caused by atherosclerosis, a build-up of fatty deposits on the artery wall, or a clot that forms within the affected artery.


Diagnosis of this type of stroke can be made based on a patient’s medical history, physical examination, and imaging tests such as an MRI or CT scan.

Differential diagnosis

Differential diagnosis for this type of stroke includes other causes of intracranial ischemia such as subarachnoid hemorrhage, arteriovenous malformation, and intracranial aneurysm.


Treatment of this type of stroke typically involves anticoagulant medications, such as aspirin or warfarin, to aid in dissolving the clot and prevent further clots from forming. In some cases, a procedure to open the blocked artery may be recommended.


The prognosis for this type of stroke varies depending on the severity of the blockage, but most patients can make a full recovery with proper treatment.
