Our primary aim with this study was to build a patient-level classifier for stroke territory in DWI using AI to facilitate fast triage of stroke to a dedicated stroke center. A retrospective collection of DWI images of 271 and 122 consecutive acute ischemic stroke patients from two centers was carried out. Pretrained MobileNetV2 and EfficientNetB0 architectures were used to classify territorial subtypes as middle cerebral artery, posterior circulation, or watershed infarcts along with normal slices.

Treating complex posterior cerebral artery (PCA) aneurysms, such as fusiform, giant, and dissecting aneurysms, poses significant challenges. Parent artery occlusion carries a risk of ischemic stroke and fails to alleviate mass effects. This study aims to analyze the technical nuances and patient outcomes of treating complex PCA aneurysms, ranging from the P1 to P2P segments, using a Zygomatic Anterolateral Temporal Approach(ZATA) combined with flow reconstruction.

Multiple strategies for tandem severe carotid artery stenosis are reported: bilateral carotid artery endarterectomy (CEA), bilateral carotid artery stenting (CAS), and hybrid procedures (CEA and CAS). The management is controversial, considering the reported high risk of periprocedural stroke, hemodynamic distress, and cerebral hyperperfusion syndrome. We present the case of a 64-year-old patient with severe symptomatic bilateral internal carotid artery stenosis (95% stenosis on the left internal carotid artery with recent ipsilateral watershed anterior cerebral artery-medial cerebral artery (ACA-MCA) and medial cerebral artery-posterior cerebral artery (MCA-PCA) ischemic strokes and 90% stenosis on the right internal carotid artery with chronic ipsilateral frontal ischemic stroke) managed successfully with staged CEA within a 3-day interval.

Background And Purpose: Fast, accurate detection of large (LVO) and medium vessel occlusion (MeVO) is critical for triage and management of acute ischemic stroke. Multiple AIbased software products are commercially available. However, their strengths and limitations for detection of vessel occlusion in the context of expanding indications for mechanical thrombectomy are not entirely understood.

Objective: To explore the factors affecting the prognosis of patients with acute posterior circulation large vessel occlusion cerebral infarction (PCO) after mechanical thrombectomy.
Method: A retrospective study was conducted on a total of 58 patients who received thrombectomy and presented within 24 h of onset with PCO from 31 September 2020 to 31 December 2022. They were divided into two groups based on a 90-day mRS score(The mRS score of 0-3 was defined as a good prognosis, and 4-6 was defined as a poor prognosis).

The choroid plexus is the secretory tissue responsible for cerebrospinal fluid production in the brain. Ischemia of the choroid plexus is rare because of its abundant blood supply from multiple arterial systems, including the anterior and posterior choroidal arterial anastomoses. It is not clear under what circumstances isolated choroid plexus infarction occurs.

Aim: This study aims to explore the effectiveness and safety of Ginkgolide in acute ischemic stroke (AIS) patients with large vessel occlusion (LVO) and moderate-to-severe stroke receiving intravenous alteplase thrombolysis (IVT).
Methods: Ginkgolide with Intravenous Alteplase Thrombolysis in Acute Ischemic Stroke Improving Neurological Function (GIANT) was an open-label, prospective, multicenter, cluster-randomized clinical trial and included AIS patients in 24 centers randomized to the intervention of intravenous Ginkgolide or control group within the first 24 h after IVT. LVO was defined as any occlusion of the internal carotid artery, M1 or M2 of the middle cerebral artery, A1 or A2 of the anterior cerebral artery, P1 of the posterior cerebral artery, and V4 of the vertebral artery or the basilar artery.

Most anatomic features of the internal carotid artery (ICA) are described as a straight course to the skull base free of branches. In some cases, the excessive elongation of the internal carotid artery in a confined space results in a curvature showing a "C" or "S" shape, or in an abnormal vascular shape made of a single or double vessel loop. These anatomic variants are called dolichoarteriopathies of the internal carotid artery.

Vascular compression of the optic nerve in a patient with rapid monocular vision loss with otherwise negative diagnostic workup is a rare, but controversial dilemma. The literature is conflicted, advocating for either timely surgical decompression to preserve vision or observation only given the prevalence of asymptomatic vascular compression and observed arrest of visual decline. The most frequently reported sources of symptomatic compression are unruptured aneurysms and dolichoectatic vasculature, with recent consensus reached over a need for extensive perioperative ophthalmologic evaluations and follow-up.

Background: Carotid web is a thin shelf-like fibrointimal membrane arising from the posterior or posterolateral wall of the carotid bulb. Webs cause stroke, especially in younger adults with high risk of recurrence.
Methods: To report the first case of de-novo formation of an asymptomatic carotid web and describe longitudinal clinical-angiographic follow-up.

Background: Decompressive craniectomies (DCs) are recommended for the treatment of raised intracranial pressure after acute ischaemic stroke. Some studies have demonstrated improved outcomes with early decompressive craniectomy (< 48 h from onset) in patients with malignant cerebral oedema following middle cerebral artery infarction. Limited data is available on suboccipital decompressive craniectomy after cerebellar infarction.

Background: Internal carotid artery (ICA) occlusion is the major cause of ischemic stroke. The effect of collateral vessels on cerebral hemodynamics in ICA occlusion remains unclear. This study investigated the correlation between collateral vessels and the peak systolic velocity of the middle cerebral artery (MCA) in patients with ICA occlusion.

Aim: To compare the features detected by high resolution magnetic resonance vessel wall imaging (HR-VWI) between posterior circulation atherosclerosis and intramural hematoma (IMH)-type dissection, and to identify indicators related to cerebral ischemic events.
Materials And Methods: Clinical and HR-VWI data of 55 patients with posterior circulation IMH-type dissection and 132 patients with posterior circulation atherosclerosis collected between October 2017 and October 2023 were analyzed retrospectively. Two radiologists independently extracted the imaging features.
Purpose: We aimed to validate hyperintense vessel sign (HVS) on FLAIR imaging or posterior cerebral artery (PCA) laterality on MR angiography beyond 4.5 hours after stroke onset.
Materials And Methods: Data from acute ischemic stroke patients with internal carotid or middle cerebral artery occlusion who underwent CT perfusion imaging at baseline, follow-up MR perfusion imaging and angiography within 30 hours after stroke, without effective recanalization on follow-up imaging, were analysed retrospectively.

In young patients, ischemic stroke is an uncommon result of vertebral artery dissection (VAD). Damage to the vertebrae can occur suddenly or as a result of trauma. There are no generally recognized recommendations for diagnosis and treatment, and the majority of vague symptoms and delayed presentation provide a significant diagnostic problem.

Context: Stroke related to giant cell arteritis (GCA) is rare and is associated with a poor outcome. One of the putative ischemic mechanisms is narrowing of the arterial lumen due to wall infiltration by inflammation and intimal proliferation, leading to reduced distal blood flow. It was hypothesized that GCA-related stroke could predominate in watershed areas (WA).

The cerebellum, a major feature of the hindbrain, lies posterior to the pons and medulla and inferior to the posterior part of the cerebrum. It lies beneath the tentorium cerebelli in the posterior cranial fossa and consists of two lateral hemispheres connected by the vermis. The cerebellum is primarily supplied by three arteries originating from the vertebrobasilar system: the superior cerebellar artery (SCA), the anterior inferior cerebellar artery (AICA), and the posterior inferior cerebellar artery (PICA).
