Pearls & Oy-sters: Cerebral venous air embolism after central catheter removal: Too much air can kill
A 95-year-old woman with a history of hypertension presented from a long-term care facility for altered mental status in the context of dehydration and hypoglycemia. Multiple attempts to obtain a peripheral IV failed, and a triple lumen catheter was placed into the right internal jugular vein using the Seldinger technique under ultrasound guidance. No complications followed the procedure. The patient was then rehydrated and given multiple ampules of D50, leading to prompt resolution of the hypoglycemia and improvement in her mental status. After resolution of symptoms, the central line was removed, with the head of the bed...

Flow diverter stents for unruptured saccular anterior circulation perforating artery aneurysms: safety, efficacy, and short-term follow-up
Conclusions Our preliminary results show that flow diversion technology is an effective and safe therapy for complex, hard-to-treat aneurysms in perforating arteries. Larger studies with long-term follow-up are needed to validate our promising results.

A Comparison of Three Different CTA Collateral Scoring Systems Ability to Predict MR Lesion Volume and Outcome after Ischemic Stroke (P6.010)
Conclusions: The CS system evaluating collaterals in the sylvian fissure of the affected vs. contralateral side correlated best with follow-up mRS and is a good predictor of lesion volume. This system could be used for prognostication in the acute setting when decisions about intervention may rely on a CTA alone.Disclosure: Dr. De Havenon has nothing to disclose.

Massive pulmonary embolism with acute cor pulmonale
A 51-year-old immobilised man, while recovering at stroke rehabilitation, complained of sudden onset chest pain prior to an unconscious collapse. Observations on arrival were heart rate 120 bpm, blood pressure 80/60 mm Hg and oxygen saturations of 90% on 10 L of oxygen. ECG demonstrated new right bundle branch block (RBBB) with classical S1Q3T3 repolarisation abnormality of acute right heart strain (figure 1A). Urgent CT pulmonary angiogram revealed saddle pulmonary embolism with extensive thrombus burden (figure 1B). Transthoracic echocardiogram (TTE) showed acute right ventricular (RV) overload with c...

Cerebral Aneurysm Morphology Before and After Rupture Clinical Sciences
Conclusions—The changes in aneurysm morphology observed after rupture reflect the compound effect of time with successive growth and formation of irregularities and the impact of rupture per se. Postrupture morphology should not be considered an adequate surrogate for the prerupture morphology in the evaluation of rupture risk.

Risk Factors for and Clinical Consequences of Multiple Intracranial Aneurysms Clinical Sciences
Conclusions—Female sex, higher age, arterial hypertension, smoking, and familial IA are major risk factors for MIA. In addition, MIA patients are at risk for enhanced IA formation. Further studies are needed to evaluate rupture risk and the role of ethnicity, especially in the context of increased MIA identification with improved neurovascular imaging.

Autoimmune limbic encephalitis in association with acute stroke
A 60-year-old woman with no known medical history presented with acute-onset altered mental status and aphasia. She was in her usual state of health until the time of presentation. She was found to have left middle and posterior cerebral artery (MCA and PCA) acute ischemic strokes and subsequently developed refractory status epilepticus. CT angiography showed moderate stenosis of the proximal left internal carotid artery (ICA), occlusion of the right ICA at its origin, and near-complete occlusion of the left vertebral artery (figure). Strokes were attributed to large-vessel atherosclerotic disease in the setting of multipl...

Early ST-segment elevation acute myocardial infarction after thrombolytic therapy for acute ischemic stroke: A case report
We report a case of STEMI occurring 40 minutes after thrombolytic therapy for AIS and discuss the possible mechanisms and therapeutic approaches. Patient concerns: A 87-year-old woman with a history of arterial hypertension was admitted for acute onset of right-sided limb weakness 2 hours before arrival at the emergency department. Forty minutes after intravenous recombinant tissue plasminogen activator (i.v. rtPA) administration for AIS, STEMI occurred (signaled by a third-degree atrioventricular block). Diagnoses: The diagnoses were AIS and STEMI. Coronary angiography confirmed right coronary artery occlusion. ...

Coiling of the Internal Carotid Artery is Associated with Hypertension in Patients Suspected of Stroke
ConclusionThe main finding of this study was the significant association of hypertension with coiling of the ICA and the absence of an association with age, plaques and atherosclerotic risk factors other than hypertension.

Ipsilateral Vocal Cord Paralysis After Acute Anterior Ischemic Stroke
CONCLUSION: Our case is a rare case of transient ipsilateral vocal cord paralysis associated with anterior unilateral cerebral ischemia. The paralysis resolved with improvement of the cerebral ischemic penumbra.PMID:33635769 | DOI:10.7812/TPP/20.104

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Correlation Between Intracranial Arterial Calcification and Imaging of Cerebral Small Vessel Disease
Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...
