E-164 Symptomatic developmental venous anomaly thrombosis associated with covid-19 infection
We describe a milder case of DVA thrombosis in the setting of COVID-19 infection presenting with unilateral hemiparesis requiring medical management alone. A 41-year-old female with hypertension who presented with left hemiparesis. Non-contrast computed tomography (CT) of head revealed linear calcifications in the right centrum semiovale consistent with DVA. Magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the right corona radiata adjacent to the vascular abnormality. Extensive workup for other causes of ischemic stroke was unrevealing. Cerebral angiography ruled out arteriovenous shunting and did not ...

Mechanical thrombectomy for acute paradoxical cerebral embolism due to pulmonary arteriovenous malformation: A case report and review of literature
CONCLUSION: Although rare, PAVM is a treatable cause of stroke in relatively young adults; thus, it is important to keep in mind the possibility of its presence.PMID:36751447 | PMC:PMC9899467 | DOI:10.25259/SNI_987_2022

Mechanical Thrombectomy for Acute Common Carotid Artery Occlusion
Neurol Med Chir (Tokyo). 2023 Jan 5. doi: 10.2176/jns-nmc.2022-0183. Online ahead of print.ABSTRACTMechanical thrombectomy (MT) is the standard treatment for acute large occlusion of the cerebral artery. Evidence for the success of this procedure was based on the treatment of patients with internal carotid artery and middle cerebral artery thrombi. There are a few reports on thrombi extending to the common carotid artery (CCA). We document our endovascular procedure and the clinical outcome in seven consecutive patients who underwent MT for CCA thrombi between September 2016 and April 2021. Their mean National Institutes o...

E-192 Association of myeloperoxidase-DNA complexes and high mobility group box 1 protein with delayed cerebral ischemia following aneurysmal subarachnoid hemorrhage
High mobility group box 1 protein (HMGB1) serves as a key player in aseptic inflammation. Admission serum HMGB1 has been identified as a biomarker predictive of delayed cerebral ischemia following aneurysmal subarachnoid hemorrhage (aSAH). Released by leucocytes and platelets, HMGB1 induces neutrophils to release condensed chromatin and protein granules, termed neutrophil extracellular traps (NETs). Myeloperoxidase (MPO)-DNA complexes are one major NET biomarker and have been associated with arterial and venous thrombosis formation. The prevalence and role of MPO-DNA in aSAH remains to be determined.A post-hoc analysis of ...

2-1-2 stroke microsurgical thrombectomy technique as a tertiary/salvage treatment option
CONCLUSIONS: 2-1-2 MST technique can be rapidly and efficaciously performed in a systemized manner offering a tertiary or salvage technique for acute stroke treatment. Specific microsurgical training is mandatory to accomplish this treatment and larger studies are necessary to confirm our hypothesis.PMID:35147401 | DOI:10.23736/S0390-5616.21.05480-1
