Vessel wall MRI evaluation for the safety of endovascular recanalization of non-acute intracranial anterior circulation artery occlusions.

Background: Vessel wall MRI (VWMRI) can reveal the morphological features of intracranial artery occlusion (ICAO). This study aimed to investigate the imaging features of ICAO on VWMRI and explore their correlation with perioperative complications of endovascular recanalization for non-acute ICAO.

Methods: The study retrospectively included consecutive patients with recurrent ischemic stroke due to non-acute ICAO in the anterior circulation who underwent preoperative VWMRI evaluation and endovascular recanalization.

Plaque features of the middle cerebral artery are associated with periprocedural complications of intracranial angioplasty and stenting.

Purpose: The identification of plaque features in the middle cerebral artery (MCA) may help minimize periprocedural complications and select patients suitable for percutaneous transluminal angioplasty and stenting (PTAS). However, relevant research is lacking.

Methods: We retrospectively included patients with symptomatic MCA stenosis who received PTAS.
