Summary: The aim of this study was to test the prognostic value of a diffusion-weighted imaging score in acute basilar artery occlusion with successful recanalization. The results showed that the PMT score had the best prognostic value, and baseline National Institute of Health stroke scale and PMT score < 5 were independent prognostic factors of favorable outcome.

Summary: The study aimed to identify factors associated with futile recanalization in acute basilar artery occlusion (ABAO) patients after successful reperfusion. The findings revealed that higher neutrophil-to-lymphocyte ratio, longer puncture to recanalization time, incomplete reperfusion, stroke severity, lower baseline posterior circulation Alberta Stroke Program Early CT score, poor collaterals, and diabetes mellitus were independent predictors of futile recanalization. These predictors can guide treatment decisions in ABAO patients undergoing reperfusion therapy.

Summary: The application of endovascular treatment (EVT) in pediatric stroke is controversial. This case report suggests that urgent EVT may achieve successful revascularization in cases of acute ischemia.

Summary: The study aimed to investigate the safety, effect, and risk factors of endovascular recanalization of symptomatic non-acute occlusion of the vertebrobasilar artery (SNOVA). The results showed that endovascular recanalization of symptomatic non-acute occlusion of the vertebrobasilar artery is feasible with a high recanalization rate, a low complication rate, and a good prognosis. Blunt occlusion and duration from the onset to recanalization may affect successful recanalization and peri-procedural complications while post-dilatation may affect in-stent restenosis and prognosis.

Summary: By developing a visualized nomogram model, we can early identify patients with basilar artery occlusion who would be at high risk of futile recanalization and assist neurologists in selecting appropriate candidates for endovascular thrombectomy.

Summary: A 59-year-old woman presented with fibrosing mediastinitis from prior coccidioidomycosis infection causing severe bilateral proximal branch pulmonary artery (PA) obstruction and right ventricular hypertension. Bilateral PA stents were placed 12 years ago. Ten years ago, the left PA stent was completely occluded and the right stent severely stenotic. A surgical right ventricle-PA homograft was placed to the right PA distal to the stent and the left PA abandoned. Cardiac computed tomography showed no flow through the left PA stent and minimal flow through the right stent. She required chronic supplemental oxygen and had dyspnea with walking for 10 years, which recently worsened, and was referred for left PA recanalization. Right ventricular systolic pressure was elevated (70 mm Hg) with no gradient through the homograft. There was external compression of the left PA stent and a bird's beak appearance to the proximal left PA with no flow through the stent. Using chronic total occlusion wires and microcatheters in a guide catheter, the left PA stent was traversed and a track serially dilated using noncompliant coronary and peripheral bal.

Summary: An effective machine learning model was developed to predict the occurrence of futile recanalization in patients with acute basilar artery occlusion who undergo endovascular treatment. Radiomics features were extracted from diffusion-weighted imaging images and used to construct a radiomics-clinical model. The model achieved satisfactory performance in preoperatively predicting futile recanalization.

Summary: This study suggests that compared with standard medical treatment, endovascular treatment (EVT) is technically feasible and safe for patients with distal basilar artery occlusion (BAO), leading to more favorable functional outcomes and decreased mortality.

Summary: The study aimed to evaluate the impact of angiographic thrombus surface phenotype on the efficacy of contact aspiration thrombectomy in patients with basilar artery occlusion. A regular thrombus surface phenotype was associated with higher rates of complete recanalization after first-line contact aspiration without rescue therapy. However, assessment of thrombus phenotype was often not feasible in basilar artery occlusion.

Summary: The study found that HR-MRI characteristics may play an important role in identifying candidates for endovascular recanalization in patients with chronic internal carotid artery occlusion. Occlusions involving the C6 segment or higher, as well as nontapered stumps, were independent negative predictors of technical success.

Summary: This study did not find a significant association between HBAS and favorable outcomes and successful recanalization in patients with BAO who underwent EVT. Larger prospective studies are needed to further investigate this relationship.

Summary: This study aimed to identify the predictors of successful endovascular recanalization in patients with symptomatic nonacute intracranial large artery occlusion (ILAO). The results showed that occlusion duration <= 3 months, tapered stump, and occlusion length < 10 mm were independent positive predictors of technical success of endovascular recanalization.

Summary: Around 30-60% of patients with basilar artery occlusion (BAO) present with coma, which is often considered as a hallmark of poor prognosis. Factors associated with acute coma in BAO patients include older age, coronary artery disease, convulsions, extensive early ischemia, absence of patent posterior collateral vasculature, and occlusion over multiple segments of BA. Younger age, less extensive baseline ischemia, recanalization, and avoiding symptomatic intracranial hemorrhage are predictors of favorable outcomes in comatose BAO patients. Older patients with cardiovascular comorbidities and unsuccessful recanalization are associated with poor outcomes.
