Cerebral revascularization surgery reduces cerebrovascular events in children with sickle cell disease and moyamoya syndrome: Results of the stroke in sickle cell revascularization surgery retrospective study.

Background: Recent studies suggest that cerebral revascularization surgery may be a safe and effective therapy to reduce stroke risk in patients with sickle cell disease and moyamoya syndrome (SCD-MMS).

Methods: We performed a multicenter, retrospective study of children with SCD-MMS treated with conservative management alone (conservative group)-chronic blood transfusion and/or hydroxyurea-versus conservative management plus surgical revascularization (surgery group). We monitored cerebrovascular event (CVE) rates-a composite of strokes and transient ischemic attacks.

Cortical Thinning in High-Grade Asymptomatic Carotid Stenosis.

Background And Purpose: High-grade carotid artery stenosis may alter hemodynamics in the ipsilateral hemisphere, but consequences of this effect are poorly understood. Cortical thinning is associated with cognitive impairment in dementia, head trauma, demyelination, and stroke. We hypothesized that hemodynamic impairment, as represented by a relative time-to-peak (TTP) delay on MRI in the hemisphere ipsilateral to the stenosis, would be associated with relative cortical thinning in that hemisphere.

Specialty Mediated 30-Day Complications in First Rib Resection for Thoracic Outlet Syndrome.

Background: Thoracic outlet syndrome (TOS) takes on heterogenous upper extremity manifestations depending on whether the artery, vein or brachial plexus is primarily compressed. As a result of these variable vascular and neurogenic symptoms, these patients present to surgeons of various training backgrounds for surgical decompression. Surgeon specialty is known to correlate with outcomes for numerous vascular procedures, but its role in TOS is unclear.
