Background: Mechanical thrombectomy is the standard therapeutic approach for eligible candidates of acute ischemic stroke according to American Heart Association/American Stroke Association guidelines. Mostly, a transfemoral approach is used to perform mechanical thrombectomy. Few studies have shown use of radial route for this procedure. Few reports have shown alternate access routes for performing mechanical thrombectomy when transfemoral or radial routes are not accessible. Design/Methods: Case report and literature review. Results: A 51-year-old female presented with left MCA stroke. Computed tomography angiography showed left internal carotid artery T occlusion extending into left MCA. Associated left atrial thrombus and occlusion at the aortic bifurcation were diagnosed in this patient. A transbrachial route was taken to perform mechanical thrombectomy in this patient resulting in complete recanalization. Conclusion: This case emphasizes the role of alternate access routes to perform mechanical thrombectomy in challenging situations.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79527642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cerebral venous sinus thrombosis (CVST) is also reported with corona virus disease-19 (COVID-19) but a large cohort study is lacking. Our aim was to study the characteristics, treatment response, and outcomes of CVST occurring in association with COVID-19 (COVID-CVST) and the causal relationship with COVID-19. Methods: Data of 34 patients admitted in COVID facility and suffering from CVST and SARS-COV2 infection was studied with respect to their clinic-radiological and lab features, predisposing factors, treatment, and outcome. Observations and Results: 15 patients with CVST were detected positive for COVID but remained asymptomatic for the same. 14 patients had CVST along with symptoms of COVID, whereas 5 had CVST after recovery from COVID, at an average of 18 days after COVID-19. 4 patients were on aspirin as prophylaxis against thrombo-embolic events. The number of males exceeded females (22:12), conventional risk factors were seen in only 8 patients (postpartum state-3, alcohol abuse-2 and anemia-3), whereas the majority (26/34) showed none of them. The mean serum homocysteine level was normal and antiphospholipid antibody was tested normal in the assessed subjects. D-dimer and C reactive protein were elevated in all. 4 symptomatic patients who suffered from severe pneumonia died because of systemic complications. Conclusion: COVID-19 predisposes to CVST and the outcome is related to the severity of COVID pneumonia. CVST related to COVID occurs during or after a few weeks of COVID pneumonia and can also be seen in asymptomatic SARS-COV2 infection. COVID-19 can occur independently or in association with traditional thrombotic risk factors which increase the risk and severity of CVST in COVID. If recognized early, CVST associated with COVID can usually be treated effectively to achieve a very good outcome.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90670582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IHS followed by early neurological worsening (change in National Institute of Health Stroke Scale [NIHSS]> 2) in acute ischemic stroke patients has been described as reversed Robin Hood syndrome (RRHS). We describe two cases of RRHS following carotid artery stenting (CAS) in patients with contralateral carotid occlusion and its further management. Two patients with a history of anterior circulation strokes presented with recent complaints of dizziness and a sensation of being pulled back (patient 1), and episodic numbness of upper limbs (patient 2). On CT angiogram, both of the patients had severe extracranial internal carotid artery (ICA) stenosis on the symptomatic side associated with complete occlusion of the ICA on the contralateral side. In addition, both patients had impaired vasomotor reactivity (VMR) on TCD in the bilateral middle cerebral artery (MCA). Therefore, CAS on the symptomatic side was performed in both patients by femoral artery access without any periprocedural and postprocedural complications. However, on day 1 post CAS, complaints of transient upper limb tingling (patient 1) and limb shaking (patient 2) were reported corresponding to the completely occluded ICA, and TCD examinations confirmed RRHS in both patients. Patients were managed by decreasing the dose of antihypertensive medication to augment the blood pressure for 2 weeks. Normalization of the VMR on TCD was seen on follow-up, and both patients remain asymptomatic.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83071199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a patient with recurrent TIA and bilateral carotid stenosis who had undergone anterior cervical diskectomy and fusion and who was found to have fibrous bands encasing the right carotid artery. He was treated with endarterectomy on the left side and carotid stenting on the right side. With the widespread availability of procedures like carotid endarterectomy, more older people would undergo this surgery, who might have undergone anterior cervical surgery. Prior neck surgery and adhesions may lead to altered anatomy, risk of increased blood loss, and surgical complications. In such cases, carotid stenting could be an alternative to endarterectomy.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78598548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Idiopathic hypereosinophilia was treated with corticosteroids and conventional parasiticidal therapy with the intention of bringing down the eosinophil count. Nephrotic syndrome was also treated with corticosteroids and immunosuppression with cyclophosphamide. Hematologic abnormalities are an important cause of arterial thrombosis with effective secondary prevention strategies. Similarly, nephrotic syndrome is not to be missed as early treatment may prevent vascular complications. While cause-effect associations remained presumptive and a single diagnostic label elusive, the patient was recognized and treated early and had a good prognosis.

We evaluated the utility of clinical, imaging parameters along with electrographic and echocardiographic biomarkers of atrial dysfunction in 2 etiological groups, namely LAA and cryptogenic strokes and compared the predictors of recurrence risk at 1 year. Methodology: All acute ischemic strokes admitted to Comprehensive Stroke Care Centre, Department of Neurology, Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum, India for 1 year (July 2019 till June 2020) with 1 year completed follow-up were screened from electronic records. Strokes secondary to LAA and undetermined cause were compared for their clinical, imaging, and cardiac variables to predict risk of recurrence in the first year. Results: Of the 179 patients, 93 had strokes secondary to LAA and 86 had cryptogenic strokes (CS). Seventy-five patients had more than 1 event at presentation/follow-up. Recurrence risk did not differ between the 2 etiological subgroups at 1 year. Hypertension (P = .016), multiple territory strokes (P = .02), and dilated left ventricle (LA) chamber (P = .047) were independently associated with recurrence risk in the entire cohort as well as within the undetermined group. Early hospitalization within 48 h reduced the overall recurrence risk (P = .01), thus emphasizing the role of early etiological evaluation and initiation of secondary prevention in reducing future events, irrespective of etiology. Conclusion: In optimally managed LAA and cryptogenic strokes, presence of hypertension, multiterritorial infarcts, and dilated LA chambers increases the recurrence risk pointing to a likely cardiac substrate itself contributing to future stroke risk.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78898302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
