Imaging of hemorrhagic stroke in magnetic induction tomography: An in vitro study
The objective of the article is to empirically investigate hemorrhagic stroke in MIT based on in vitro study and to improve stroke detectability and visibility to help monitoring stroke patients. The following approaches were evaluated: (i) level setting, (ii) improved spatial filtering, (iii) averaging of multiple measurements, (iv) the combinations of these three approaches, and (v) wavelet denoising. They were evaluated with an in vitro phantom resembling a cerebral stroke in a pig brain. The results showed that these approaches enhanced stroke visibility, lowered stroke detectability threshold from 15 ml to 5 ml, and i...

Femoral Access-Site Complications with Tenecteplase versus Alteplase before Mechanical Thrombectomy for Large-Vessel-Occlusion Stroke INTERVENTIONAL
CONCLUSIONS: Tenecteplase compared with alteplase before mechanical thrombectomy for large-vessel-occlusion stroke is not associated with an alteration in femoral access-site complication rates.

Recanalization with Stent-Retriever Devices in Patients with Wake-Up Stroke INTERVENTIONAL
CONCLUSIONS: Despite successful and rapid recanalization with stent-retriever devices, good clinical outcome in patients with wake-up stroke is achieved in a minority of patients. Clinical outcome remains poor. Bleeding rates were higher compared with recanalization procedures within 6 hours after stroke onset.

Prehospital management of acute stroke : Using the example of Saarland ambulance services.
CONCLUSIONS: With good traffic and hospital infrastructure in Saarland, severe strokes can be treated primarily in neurovascular centers. Differentiated care requirements with monitoring of key figures in medical quality management and clear agreements with the target hospitals in the implementation of a common care strategy are essential.

Use of intravenous cangrelor and stenting in acute ischemic stroke interventions: a new single center analysis and pooled-analysis of current studies
CONCLUSIONS: IV cangrelor during acute ischemic stroke intervention appears to be safe, with a symptomatic intracranial hemorrhage rate of 6.2%. More research is needed to determine the ideal dosing regimen.PMID:33945341 | DOI:10.1177/15910199211014417

Complications of Endovascular Treatment for Acute Stroke in the SWIFT Trial with Solitaire and Merci Devices EVIDENCE-BASED MEDICINE LEVEL 2
CONCLUSIONS: Understanding of procedural complications is important for treatment of patients with stroke after endovascular treatment. We observed fewer endovascular complications with the Solitaire FR device treatment compared with Merci device treatment, particularly symptomatic cerebral hemorrhage.

Embolic stroke secondary to spontaneous thrombosis of unruptured intracranial aneurysm: Report of three cases.
We present the clinical outcome and radiological characteristics of three patients with spontaneous thrombosis of intracranial aneurysms as a cause of ischemic stroke. This information is relevant given the possible benign history in terms of stroke recurrence and risk of bleeding. PMID: 26647229 [PubMed - as supplied by publisher]

Favorable first-pass recanalization rates with NeVa ™ thrombectomy device in acute stroke patients: Initial clinical experience.
CONCLUSIONS: In our experience, the NeVa™ device demonstrated high first-pass and overall recanalization rates along with a good safety profile. PMID: 32615827 [PubMed - as supplied by publisher]

The Effect of Dabigatran Plasma Concentrations and Patient Characteristics on the Frequency of Ischemic Stroke and Major Bleeding in Atrial Fibrillation Patients The RE-LY Trial (Randomized Evaluation of Long-Term Anticoagulation Therapy)
ObjectivesThe goal of this study was to analyze the impact of dabigatran plasma concentrations, patient demographics, and aspirin (ASA) use on frequencies of ischemic strokes/systemic emboli and major bleeds in atrial fibrillation patients.BackgroundThe efficacy and safety of dabigatran etexilate were demonstrated in the RE-LY (Randomized Evaluation of Long-Term Anticoagulation Therapy) trial, but a therapeutic concentration range has not been defined.MethodsIn a pre-specified analysis of RE-LY, plasma concentrations of dabigatran were determined in patients treated with dabigatran etexilate 110 mg twice daily (bid) or 150...

Flat Detector Angio-CT following Intra-Arterial Therapy of Acute Ischemic Stroke: Identification of Hemorrhage and Distinction from Contrast Accumulation due to Blood-Brain Barrier Disruption INTERVENTIONAL
CONCLUSIONS: Flat panel CT after endovascular stroke treatment was able to exclude the rare event of an intracranial hemorrhage with a high negative predictive value. Future studies should evaluate the predictive value of BBB disruptions in flat panel detector CT for the development of relevant hematomas.

Incident of Stroke after Transradial  Arterial Access for Subdiaphragmatic Intervention
Transradial access (TRA) for noncoronary interventions has gained increasing popularity during the past several years. A retrospective analysis of 1,500 cases (1) demonstrated a major complication rate of 0.13%, with no reported cases of stroke. TRA has several advantages, including decreased risk of life-threatening bleeding and patient comfort. However, TRA has the associated complication of stroke that is not seen with subdiaphragmatic interventions performed via transfemoral access (TFA). Here we present a case of stroke after a TRA for yttrium-90 (90Y) radioembolization.

The role of multimodal imaging in stroke code patients.
Abstract In stroke code patients, multimodal imaging workup encompasses various imaging techniques, including baseline computed tomography (CT), magnetic resonance (MR) imaging, diffusion MR imaging, CT or MR perfusion studies, and CT or MR angiography, that are used to rule out bleeding, confirm arterial occlusion, establish tissue viability, and help select candidates for endovascular treatment as early as possible. Five recently published relevant clinical trials have demonstrated the efficacy of mechanical thrombectomy in proximal arterial occlusions; all these trials used different imaging techniques to selec...

Safety profile of an 8F femoral arteriotomy closure using the Angio-Seal device in thrombolysed acute stroke patients undergoing thrombectomy.
Conclusion Use of the Angio-Seal closure device for 8F femoral access is safe in acute stroke patients. Intravenous thrombolysis prior to endovascular thrombectomy does not significantly alter femoral access site complication rate if this approach is used.
