Background And Purpose: A large proportion of ischemic stroke patients lack a definitive stroke etiology despite extensive diagnostic testing. Varicella-Zoster Virus (VZV) can directly invade blood vessels causing vasculitis and may be associated with cryptogenic stroke (CS).
Methods: We conducted a retrospective cross-sectional study of CS patients tested for VZV.
Objectives: The Distal Motor Function (DMF) sub-score of the NIH Stroke Scale (NIHSS) was measured in the NINDS rt-PA Stroke Trials but is currently not included in the NIHSS. The correlation of DMF with the NIHSS Motor Arm Function (MAF) sub-score, the effect of IV tPA treatment on DMF, and whether adding DMF changes the utility of the NIHSS have not been analyzed.
Materials And Methods: MAF and DMF sub-scores were retrieved from the original NINDS rt-PA Stroke Trials for both sides of the body at baseline, 2 hours, 24 hours, 7-10 days, and 3 months after IV tPA treatment.
Cerebral Hyperperfusion Syndrome After Carotid Revascularization and Acute Ischemic Stroke.
Curr Pain Headache Rep
March 2018
Purpose Of Review: Cerebral hyperperfusion syndrome (CHS) is a rare but significant complication after carotid revascularization and is increasingly recognized after acute stroke treatments. In this review, we discuss the epidemiology and pathophysiology of CHS, clinical presentation including ipsilateral headache, seizures, and focal neurological deficits, and radiographic presentation. We propose preventive therapies with emphasis on acute stroke post-thrombectomy hyperperfusion.

- A 34-year-old woman experienced postpartum complications, including weakness and headaches, 14 days after giving birth, leading to the discovery of bilateral carotid artery dissections and cerebral infarctions through imaging.
- The condition is rare, particularly in women without known risk factors, and may be influenced by factors related to pregnancy and childbirth, such as hormonal changes and the Valsalva maneuver during labor.
- Treatment involves anticoagulation therapy for 3 to 6 months and regular follow-ups to monitor recovery through neuroimaging.
Common carotid artery dissection: a case report and review of the literature.
J Stroke Cerebrovasc Dis
January 2012
Common carotid artery dissection (CCAD) is a rare and poorly characterized cause of ischemic stroke. We describe a case of multiple cerebral infarcts in a patient with CCAD initially detected by carotid duplex ultrasonography, and review the literature on CCAD. A Medline search from 1960 to the present for cases of CCAD yielded 46 cases.
