Intracerebral hemorrhage (ICH) is a main complication of IVT, with prevalence reported around 3.2% CT angiography (CTA) showed near occlusive stenosis of the left carotid bulb with an acute thrombus within Supraclinoid Internal Carotid Artery (ICA) extending into the Left MCA and origin of Left Anterior Cerebral Artery (ACA).

Background:Hyperperfusion phenomenon (HPP) constitutes a significant risk factor for adverse outcomes following carotid artery stenting (CAS). Stroke, Volume 56, Issue Suppl_1 , Page ATP178-ATP178, February 1, 2025. Currently, the sole method for evaluating the risk of HPP post-CAS is the invasive acetazolamide (ACZ) challenge test.

Most neurointerventionalists (91%) diagnose ICAS‐LVO after a continued or recurrent occlusion or by the presence of fixed focal stenosis after multiple mechanical thrombectomy attempts. Most respondents (86%) preferred acute treatment of ICAS‐LVO with rescue stenting (RS)±angioplasty.

Treatment of ICAS‐LVO with rescue stenting and/or angioplasty has shown promising outcomes, but diagnosing ICAS‐LVO during MT can be challenging [2, 3]. Most neurointerventionalists (91%) diagnose ICAS‐LVO after a continued or recurrent occlusion or by the presence of fixed focal stenosis (FFS) after multiple MT attempts.

The PREMIER study first demonstrated high rates of complete occlusion without parent vessel stenosis or permanent neurological complications after the treatment of wide-necked small and medium-sized intracranial ICA aneurysms with the 48-wire pipeline. Median aneurysm and neck size were 5.8 mm (IQR: 4.0-7.5) At a median 10.1 months (IQR: 6.3-12.6),
