Increased volumes of mildly elevated capillary transit time heterogeneity positively predict favorable outcome and negatively predict intracranial hemorrhage in acute ischemic stroke with large vessel occlusion.
CONCLUSION: An increased volume of mildly elevated CTH is a positive predictor of favorable outcome and a negative predictor for ICH in patients with acute ischemic stroke and mismatch undergoing ET. KEY POINTS: • The classification of potentially salvageable tissue and infarct core based on traditional net perfusion parameters (as Tmax or CBF) does not account for the microvascular distribution of blood. • However, the microvascular distribution of blood, as indexed by the capillary transit time heterogeneity (CTH), directly affects the availability of oxygen within the hypoperfused tissue and should therefore be...

Three Dimensional-Arterial Spin Labeling Evaluation of Improved Cerebral Perfusion After Limb Remote Ischemic Preconditioning in a Rat Model of Focal Ischemic Stroke
CONCLUSION: Three dimensional (3D) ASL can be used to evaluate LRP to improve stroke perfusion, and its protective effect may be closely related to LRP-induced vascular regeneration.PMID:35847828 | PMC:PMC9280338 | DOI:10.3389/fnana.2022.893953

Efficacy of CT-Perfusion Study in Differentiating Seizures from Acute Stroke Prior to Initiating Tissue Plasminogen Activator Therapy (P02.033)
CONCLUSIONS: CT-Perfusion studies exhibit increased cerebral blood flow in seizures in constrast to decreased blood flow in ischemic events. It can help differentiate an acute stroke from an ictal discharge and can assist in preventing improper use of TPA and hemorrhagic complications.Disclosure: Dr. Ahmed has nothing to disclose.

Mechanical Thrombectomy in Acute Stroke Due to Carotid Occlusion: A Series of 153 Consecutive Patients
Conclusions: In our population, patients with CAO clinically present with severe strokes. Isolated occlusions of the extra- or intracranial segments of the carotid are more frequent than tandem occlusions. Successful recanalization after thrombectomy is achieved in most of the patients, but association with favorable functional outcome is poor. Clinical evolution is similar in patients treated with PMT and BT. Intracranial symptomatic hemorrhage after treatment is associated with higher intrahospital mortality and worse 3 months-mRS. Poor perfusion-CT mismatch, symptomatic hemorrhage, and isolated CAO are independent predi...

COVID-19–Associated Ischemic Stroke in a Patient on Therapeutic Anticoagulation
Conclusion: Ischemic stroke in anticoagulated patients with COVID-19 has been previously reported. Such cases emphasize the severity of the coronavirus virus associated hypercoagulable state. A majority of reported cases have occurred in patients continuing their ambulatory therapy. Overall, such cases are likely underreported. There are current trials comparing therapeutic versus prophylactic dose anticoagulation in patients with COVID-19. There are no studies specifically addressing anticoagulation agent failure in these patients. Further research is required this area to determine the optimal therapy for patients with COVID-19.

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

Older Age, Hypertension and Diabetes Influence the Proportion of Salvageable Ischemic Tissue Following Ischemic Stroke (P02.048)
CONCLUSIONS: Older patients and those with HTN or DM are less likely to have a large proportion of salvageable penumbra. While endothelial dysfunction may be a common denominator to these risk factors, the biological mechanisms underlying this phenomenon need to be elucidated.Disclosure: Dr. Mohamed has nothing to disclose.
