We present the case of a middle-aged patient who had four recurrent acute basilar artery occlusions over a period of 3 months, each time successfully treated with mechanical thrombectomy. Extensive stroke work-up showed no obvious stroke etiology aside from a dysplastic right vertebral artery with multifocal stenoses. Treatment with different antiplatelet and anticoagulant regimes did not prevent basilar artery occlusion recurrence. Therefore, transarterial coil occlusion of the V4-segment of the right vertebral artery was performed as ultima ratio without complications. At final discharge, the patient had no persistent neurological deficits. No further cerebrovascular events occurred over a 12-month follow-up period.

This paper presents the case report of an 11-year-old boy with an acute dissection with thrombosis of the left vertebral artery and thrombosis of the basilar artery. The patient was treated with acute systemic thrombolysis, followed by intra-arterial thrombolysis, without any clinical improvement, showing left hemiplegia, bilateral clonus, hyperreflexia, and impaired consciousness. MRI indicated persistent thrombosis of the arteria basilaris with edema and ischemia of the right brainstem. Heparinization for 72 hours, followed by a two-week LMWH treatment and subsequent oral warfarin therapy, resulted in a lasting improvement of the symptoms. Vertebral artery dissection after minor trauma is rare in children. While acute basilar artery occlusion as a complication is even more infrequent, it is potentially fatal, which means that prompt diagnosis and treatment are imperative. The lack of class I recommendation guidelines for children regarding treatment of vertebral artery dissection and basilar artery occlusion means that initial and follow-up management both require a multidisciplinary approach to coordinate emergency, critical care, interventional radiology, and child neurology services.

Context: Stroke caused by basilar artery occlusion is rare, corresponding to 1% of strokes. There is no consensus in the literature on the ideal management of this disease at acute phase. However, mechanical thrombectomy may be a viable treatment option. Case report: 68-year-old female, with no comorbidities, admitted to a secondary hospital 14h after headache, dizziness, vomiting and difficulty walking. She was disoriented, with severe dysarthria and dysphonia, horizontal and vertical ophthalmoparesis and pronation of the right upper limb (NIHSS: 4). Cranial tomography was normal and cranial angiotomography showed a basilar artery thrombosis. Patient was out of the window for intravenous thrombolysis and our hospital did not have another possibility of treatment. Due to high morbidity and mortality, also the possibility of neurological deterioration, medical contact was made with a tertiary hospital with hemodynamic service. During patient transference, she evolved with decreased level of consciousness, aphasia and tetraparesis (NIHSS: 18). Upon arrival at the hospital, a thrombectomy was performed due to an important clinical-radiological mismatch, 19 hours within symptoms onset and 3 hours after neurological worsening. After discharge, patient walked with assistance and physical examination showed a significant improvement in neurological deficits (NIHSS: 6). Conclusions: This case demonstrates the importance of engaging Brazil’s public health system in the management of acute ischemic stroke, especially in challenging cases such as basilar artery occlusion. This patient was the first admitted to our hospital to perform a thrombectomy after effective transference for a tertiary hospital and staff engagement of both hospitals.

Background: Vertebral artery stump syndrome (VASS) develops into recurrent posterior circulation ischemic stroke after ipsilateral vertebral artery (VA) occlusion at its origin. Case Description: The patient was a 46-year-old man with the right posterior cerebral artery occlusion. We used a recombinant tissue plasminogen activator (rt-PA) and then performed mechanical thrombectomy using a stent retriever. Angiography revealed left VA occlusion and stagnant flow to the left VA from the right deep cervical artery; therefore, we diagnosed VASS. Within 24 h of the rt-PA injection, the symptoms had dramatically improved, and so we avoided additional antithrombotic agents. Only 13 h later, the patient developed a basilar artery occlusion and died in spite of a repeated mechanical thrombectomy. Conclusion: Vigilance against early (and sometimes fatal) recurrent stroke induced by VASS is required.

Rationale There are no randomized trials examining the best treatment for acute basilar artery occlusion in the 6–24-hour time window. Aims To assess the safety and efficacy of thrombectomy for stroke due to basilar artery occlusion in patients randomized within 6–24 h from symptom onset or time last seen well. Sample size For an estimated difference of 20% in proportions of the primary outcome between the two groups, 318 patients will be included for 5% significance and 90% power with a planned interim analysis after two-thirds of the sample size (212 patients) have achieved the 90 days follow-up. Methods and design A prospective, multi-center, randomized, controlled, open-label and blinded-endpoint trial. The randomization employs a 1:1 ratio of mechanical thrombectomy with the detachable Solitaire thrombectomy device and best medical therapy (BMT) vs. BMT alone. Study outcomes The primary outcome will be the proportion of patients achieving modified Rankin Scale (mRS) 0–3 at 90 days. Key secondary outcomes are: dramatic early favorable response, dichotomized mRS score (0–2 vs. 3–6 and 0–4 vs. 5–6) at 90 days, ordinal (shift) mRS analysis at 90 days, infarct volume at 24 h, vessel recanalization at 24 h in both treatment arms, and successful recanalization in the thrombectomy arm according to the modified thrombolysis in cerebral infarction (mTICI) classification defined as mTICI 2 b or 3. Safety variables are mortality at 90 days, symptomatic intracranial hemorrhage rates at 24 h, and procedure-related complications. Discussion Results from this trial will indicate whether mechanical thrombectomy is superior to medical management alone in achieving favorable outcomes in subjects with acute stroke caused by basilar artery occlusion presenting within 6–24 h from symptom onset.

Background and Purpose: Convulsive seizures related to posterior circulation stroke are considered rare. However, some patients with acute basilar artery occlusion (BAO) can present with convulsive movements. Misdiagnosed as seizures may delay the reperfusion therapy for acute BAO. In this study, we have summarized the clinical features and possible mechanisms of BAO presenting with convulsive movements.Methods: We performed an Institutional Review Board-approved institutional database query from 2015 to 2020 and a literature search of the online database PubMed. Clinical data were collected and analyzed.Results: In total, 14 patients with acute BAO presented with convulsions. There were 10 men and 4 women, with a mean age of 53 (range, 23–77) years. All of these patients had different degrees of impaired consciousness (100.0%, 14/14). Convulsive movements were the initial symptoms in 78.6% (11/14) of patients. Further, 64.3% (9/14) of patients presented with paralysis or cranial nerve abnormalities, and 85.7% (12/14) of patients were treated with reperfusion therapy (thrombolysis, 35.7% [5/14]; endovascular thrombectomy, 64.3% [9/14]). The BAO etiology and mechanism were related to embolism, vessel dissections, and severe stenosis of the right vertebral artery in 57.1% (8/14), 21.4% (3/14), and 7.1% (1/14) of patients, respectively; they were undefined in 14.3% (2/14) of patients. Moreover, 42.9% (6/14) of patients had a 90-day modified Rankin Scale score of 0–2, and the mortality rate was 21.4% (3/14).Conclusions: Acute BAO, especially that related to embolism or vessel dissection, may present with convulsive movements. Acute BAO is a devastating, but treatable disease if diagnosed in time. Considering the possibility of BAO is important when dealing with patients presenting with acute-onset convulsive movements. Prompt diagnosis and reperfusion therapy may help achieve a better prognosis.

Introduction : Performing mechanical thrombectomy (MT) in patients with basilar artery occlusion (BAO) is currently not evidence‐based. In the real‐world practice, it is also often encountered that the delayed initiation of the MT happens for this particular patient groups due to lack of cortical signs and other medical confounding factors. Methods : We retrospectively analyzed the angiographical and clinical outcomes of consecutive BAO patient who underwent MT in single institution. Onset to treatment (OTT), Door to Puncture (DTP) time were compared with those in anterior circulation large vessel occlusion (ACLVO) group who underwent MT in the same time period. For those showed significantly longer DTP time, the factors associated with the delayed initiation of the MT were analyzed. Results : A total of 271 patients underwent mechanical thrombectomy at UCI Medical Center between Jan 2016 and June 2021. Of these, 32 patients diagnosed as BAO by CTA and underwent MT were included in the study. Successful recanalization was achieved in 28 cases (87.5%), and symptomatic ICH occurred in 3 cases (9.4%). Nine patients (28.1%) showed good clinical outcomes (mRS 0–3) at 3 months. The median Onset to Puncture Time (OTT) was 340 min. The median DTP time (145 min) was significantly longer as compared to the ACLVO patients (99 min) (p value = 0.04). Of the 6 patients who showed significant delay in the initiation of intervention (DTP>300 min), 5 patients (83.3%) did not have the initial “stroke‐code activation” at the time of ED arrival. The cause of the delay was due to lack of cortical sign (3), bilateral spontaneous sustained clonus, which misinterpreted as seizure (1), AMS with non‐focal neurological signs interpreted as encephalopathy (2). Conclusions : DTP of the patients who underwent MT for BAO was significantly longer than that in ACLAO. Lack of cortical sings which are markers of ACLVO were associated with delayed activation of stroke code. Establishment of BAO screening in the ED assessment and prompt activation of Stroke code may contribute to the improvement of MT treatment for the BAO patients.

Objectives: To describe the clinical and epidemiological characteristics of patients with basilar artery occlusion (BAO) treated with mechanical thrombectomy (MT) in Aragón, and to compare its anaesthetic management, technical effectivity, security, and prognosis with those of anterior circulation. Methods: 322 patients from the prospective registry of mechanical thrombectomies from Aragon were assessed: 29 with BAO and 293 with an anterior circulation large vessel occlusion. Baseline characteristics, procedural, clinical and safety outcomes variables were compared. Results: Out of 29 patients with BAO that underwent endovascular therapy (62.1% men; average age 69.8 ± 14.05 years) 18 (62.1%) received endovascular therapy (EVT) alone and 11 (37.9%) EVT plus intravenous thrombolysis. Atherothrombotic stroke was the most common etiology (41%). The BAO group had longer Door-to-groin (160 vs 141 min; P = 0.043) and Onset-to-reperfusion times (340 vs 297 min; P = 0.005), and higher use of general anaesthesia (60.7% vs 14.7%; P < 0.01). No statistically significant difference was found for Procedure time (60 vs 50 min; P = 0.231) nor the rate of successful recanalization (72.4% vs 82.7%; P = 0.171). Functional independence at 90 days was significantly worse in the BAO group (17.9% vs 38.2%; P < 0.01). Conclusions: Patients with basilar artery occlusion had higher morbimortality despite similar angiographic results. Mechanical thrombectomy for BAOs is a safe and effective procedure in selected patients. A consensus about the effect of anaesthesia has yet to be reached, for BAO general anaesthesia remains the most frequently used technique.
