Purpose The purpose of this article is to assess the efficacy and safety of manual aspiration thrombectomy (MAT) using a Penumbra catheter in patients with anterior cerebral artery (ACA) occlusions. Materials and methods From January 2012 to March 2016, 16 patients underwent MAT with Penumbra catheters using a proximal and distal supporting technique to treat ACA occlusions. We evaluated immediate angiographic results and clinical outcomes by reviewing patient electrical medical records. Results Of these patients, 11 had a complete obstruction of the distal internal carotid artery (ICA) and five had ACA and middle cerebral artery (MCA) occlusions. All patients achieved successful recanalization of the distal ICA or MCA (Thrombolysis in Cerebral Infarction (TICI) grade ≥2b). Overall the recanalization rate for ACA occlusions (TICI grade≥2b) was 93.7% (15/16). The median procedure time was 45 minutes (range: 35-65 minutes). No patients were observed to have a procedure-related subarachnoid hemorrhage. Four patients (25.0%) died during hospitalization because of massive symptomatic hemorrhage, brain edema, or herniation. At discharge, the median NIHSS score for surviving patients was 6 (range: 1-17). Five patients had favorable clinical outcomes (modified Rankin scale ≤2). Conclusion MAT appears to be safe and successfully achieves recanalization in patients with ACA occlusions.

Prognostic analysis of endovascular mechanical thrombectomy in stroke patients with acute internal carotid artery obstruction based on circle of Willis variation.

Objective: Endovascular mechanical thrombectomy (EVMT) is widely employed in patients with acute intracranial carotid artery occlusion (AIICAO). This study aimed to predict the outcomes of EVMT following AIICAO by utilizing anatomic classification of the circle of Willis and its relative position to the thrombus.
Methods: In this study, we retrospectively analyzed a cohort of 108 patients with AIICAO who underwent endovascular mechanical thrombectomy (EVMT) at Shaoxing People's Hospital.

Injury of the internal carotid artery (ICA), anterior cerebral artery (ACA), and middle cerebral artery (MCA) are rare but devastating complications during microsurgery of the anterior and middle cranial skull base. We systematically reviewed the current knowledge on ICA, ACA, and MCA injury during skull base microsurgery and performed a multicentric data collection to refine their management. A systematic review of ICA, ACA, and MCA injuries during direct microsurgical approaches to the anterior and middle cranial skull base was performed, using PRISMA-IPD guidelines and using a multicentric case collection.

Background And Purpose: Leptomeningeal collaterals have been associated with better outcomes in large-vessel stroke, but little is known about how the Circle of Willis (CoW) collaterals affect stroke outcomes. We aimed to determine the relationship between three anatomically distinct CoW subtypes and 90-day outcomes in acute ischemic stroke patients after successful revascularization via endovascular thrombectomy (EVT).
Materials And Methods: We performed a retrospective analysis of patients treated with successful EVT for large-vessel occlusion at a comprehensive stroke center between May 2016 and November 2023.

Background: With the refinement of catheter technology, distal medium vessel occlusions (DMVOs) are now viewed as amenable to endovascular treatment (EVT) but its efficacy and safety remains unclear in AIS patients with DMVO.
Methods: We conducted a systematic search of PubMed, Embase databases and Cochrane Library up to December 2023 using keywords to identify studies comparing EVT versus BMT in AIS with DMVOs. The assessed clinical outcomes were excellent functional outcome, good functional outcome, 90-day mortality, symptomatic intracranial hemorrhage (sICH), and early neurological improvement (ENI) after treatment.

Background: Anterior cerebral artery (ACA) occlusions account for up to 4 % of all acute ischemic strokes and may lead to debilitating outcomes. While endovascular thrombectomy (EVT) is a well-established treatment for large vessel occlusions, its efficacy and safety for primary ACA occlusions remains unclear. This systematic review and meta-analysis aims to address this gap by evaluating the clinical outcomes, safety, and efficacy of EVT in the treatment for primary ACA occlusions.
