The Acute Ischemic Stroke (AIS) module variables consist of patient demographics, patient history, procedure and post-op, with a separate follow-up form.

Inclusion & Clinical Description:

AIS procedures occurring within 24 hours of stroke symptom onset. AIS intervention involves endovascular thrombolysis or mechanical embolectomy performed for acute cervical or intracranial occlusion of the carotid artery (above C1) and its branches or the vertebrobasilar system and its branches. Typically, the intracranial internal carotid artery or middle cerebral artery are treated, and may include more than one occlusion. Additionally, an AIS procedure may be performed in conjunction with an angioplasty or stenting of the cervical carotid (C1 and below); the angioplasty or stenting should be separately entered on the carotid artery stent procedure module.

Follow-up Requirement:

Follow-up may be captured at 30-days, 90-days, and one-year post procedure date, with the goal of achieving an 80% follow-up rate at 90 days.
