Venous return in acute ischaemic stroke patients measured during computed tomography angiography of head and neck
CONCLUSIONS: Although no clinical benefit was proven as a result of measuring the time it took contrast media to reach the aorta, our study implies that not only is the brain subject to circulation, but it may also affect its functioning.PMID:34477214 | DOI:10.5603/PJNNS.a2021.0060

HSV-Encephalitis Resembling Acute Cerebral Infarction in a Patient With Atrial Fibrillation: Beware of Stroke Mimics
Conclusion: HSV-encephalitis might occasionally result in the development of unilateral brain MRI lesions with extensive cytotoxic edema, resembling an acute ischemic stroke. Therefore, HSV-encephalitis must be considered in the differential diagnosis of acute ischemic stroke with atypical presentation. The presence of a significant dissociation between the brain MRI lesion volume and the neurological deficits, as well as certain brain MRI imaging discrepancies might serve as “red flags” to extend the diagnostic workup.

Predictors and Outcomes of Salvaging the Corticospinal Tract After Thrombectomy in Basilar Artery Occlusion Stroke
ConclusionCST salvage was associated with good functional outcomes in patients with BAO treated with thrombectomy. The presence of atrial fibrillation, location and length of BAO may predict CST salvage after thrombectomy, and rapid treatment with thrombectomy may protect this eloquent tract in these patients.

P-005 Predictors for large vessel recanalization before stroke thrombectomy
ConclusionsIVT at least 1.5 hours before angiography, site of vascular occlusion, atrial fibrillation, and hyperlipidemia are independent predictors for LVR. The 8-point Recan score proposed in this study may be a valuable tool for predicting LVR before EVT.Abstract P-005 Figure 1Disclosures H. Chen: None. M. Colasurdo: None. C. Schrier: None. M.

Dual potential embolic source detected in left atrium during hyperacute stroke
Clinical introduction A woman in her late 60s with a medical history of hypertension presented to the emergency department with symptoms of a stroke which began 40 min prior. Brain MRI was performed (figure 1A). Hyperacute CT angiography of the head and neck did not find any atherosclerosis. ECG is shown (figure 1B), and subsequent transthoracic echocardiography showed left atrium enlargement and left-to-right flow at the region of the fossa ovalis (figure 1C). Figure 1Brain MRI of diffusion-weighted image sequence (A), ECG (B), and transthoracic echocardiogram (C). Question Which of the following is the most likely mechan...

Initial Experience With a Novel Percutaneous Left Atrial Appendage Exclusion Device in Patients With Atrial Fibrillation, Increased Stroke Risk, and Contraindications to Anticoagulation
Atrial fibrillation (AF) increases by fivefold a patient's risk for thromboembolic stroke. The main source of emboli in AF is the left atrial appendage (LAA). Therefore, LAA closure could reduce the risk for thromboembolic events in AF. The investigators report the first United States experience with a novel percutaneous LAA closure device, the Lariat snare device, and its outcomes in 21 patients with AF, CHADS2 scores ≥2, and contraindications to anticoagulation. The LAA was closed with a snare containing suture from within the pericardial space. The intraoperative success of the procedure was confirmed by left atrial a...

Simultaneous onset of myocardial infarction and ischemic stroke in a patient with atrial fibrillation: Multiple territory injury revealed on angiography and magnetic resonance
An 84-year-old man with a history of hypertension and paroxysmal atrial fibrillation (AF) who received no anticoagulant drugs experienced acute chest pain and transient loss of consciousness. He was transferred to our emergency room. His initial electrocardiogram showed sinus rhythm with ST-segment elevation in the I, aVL, and V1–V6 leads. His blood pressure was 158/92mmHg and his pulse was regular at 70beats per minute. A chest radiograph showed increased heart size and pulmonary vascular congestion. His troponin T level was elevated (more than 0.1ng/mL). He was diagnosed with ST-elevation myocardial infarction (MI) and...

Intraoperative stroke in the mandibular osteoradionecrosis: A case report
Publication date: January 2015 Source:Journal of Oral and Maxillofacial Surgery, Medicine, and Pathology, Volume 27, Issue 1 Author(s): Ryo Sasaki , Chie Kagawa , Toshihiro Okamoto , Tomohiro Ando Although risk factors for perioperative stroke during head and neck surgery are known, the risk of perioperative stroke in osteoradionecrosis (ORN) patients is scarcely known. Sixty-seven-year-old male presented ORN in the mandible after 9 years docetaxel, cisplatin, and 5-fluorouracil (TPF) chemo, and 66Gy radiation therapies for the oropharynx cancer, which was diagnosed Marx's classification class II. After pre-operative hyp...

P-015 flow stasis after the deployment of stent-retriever predicts successful final recanalization in acute stroke patients
ConclusionLoss of IFR effect during the embedding time after deployment of stent retriever was associated with successful recanalization. It may be an angiographic sign of adequate thrombus engagement with the stent retriever. This observation may be useful in order to optimize the embedding time during which a stent retriever cuts into the occlusive thrombus particularly when a new stent retriever is introduced to the clinical practice.DisclosuresS.

Collateral Vessels on 4D CTA as a Predictor of Hemorrhage Transformation After Endovascular Treatments in Patients With Acute Ischemic Stroke: A Single-Center Study
Conclusions: Patients with poor collateral circulation are at a higher risk of HT after receiving endovascular therapy. Thus, variations in collateral circulation based on 4D CTA may be an important factor for personalized clinical treatments. In addition, high blood glucose, atrial fibrillation and the baseline NIHSS score are all important independent predictors of HT.

Mesial bifrontal stroke presenting as isolated spontaneous confabulations.
Abstract A 52-year-old man with paroxysmal atrial fibrillation presented with spontaneous confabulation, working memory deficits, and frontal release signs. MR scan of brain showed bifrontal mesial ischaemic strokes and angiography demonstrated that both anterior cerebral arteries were supplied by the left internal carotid artery. Isolated spontaneous confabulation is a rare presentation of stroke and may be associated with orbitofrontal cortex lesions. Interestingly, functional imaging during rapid-eye-movement sleep may show bilateral medial frontal lobe hypometabolism, suggesting anatomical overlap between drea...

E-025 Aspiration thrombectomy of acute ischemic stroke patients with intracranial atherosclerotic disease or tandem lesion
ConclusionAspiration thrombectomy was effective in restoring blood flow and resulting in good 90-day functional outcome in AIS patients with anterior circulation tandem lesion, and the 90-day mortality rate in these patients was low. No significant difference in outcomes was detected between patients with a stent and patients without a stent.Disclosures O.
