Spinal cord ischemia(SCI) has been devastating complication of endovascular thoracic and thoracoabdominal aortic repair. Spinal cord blood supply arises from not only segmental artery, subclavian artery, hypogastric artery and these branches, but also perivertebral vasculature and paravertebral muscle and small arterial network, and risk factors of SCI were multifactorial. There are several adjuncts/strategies which are utilized to minimize the incidence of SCI: cerebrospinal fluid drainage, perioperative management of high mean arterial pressure, intraoperative evoked potential monitoring, and staged thoracoabdominal aortic repair...

OBJECTIVE Subarachnoid hemorrhage (SAH) is treated with either surgical clipping or endovascular coiling, though the latter is the preferred treatment method given its more favorable functional outcomes. However, neuropsychological functioning after treatment is rarely taken into account. In this meta-analysis, the authors synthesized relevant data from the literature and compared neuropsychological functioning in patients after coiling and clipping of SAH. They hypothesized that the coiled patients would outperform the clipped patients; that group differences would be greater with higher posterior circulation rupture rates, in older patients, and in more recent publications; that group differences would be smaller with greater rates of middle cerebral artery (MCA) rupture; and that anterior communicating artery (ACoA) rupture rates would not influence effect sizes...

OBJECTIVE The recurrence rate of vertebrobasilar dissecting aneurysms (VBDAs) after reconstructive endovascular treatment (EVT) is relatively high. The aneurysm wall enhancement on high-resolution MRI (HRMRI) reportedly predicts an unsteady state of an intracranial aneurysm. The authors used HRMRI to investigate the relationship between wall enhancement on HRMRI and progression of VBDAs after reconstructive EVT. METHODS From January 2012 to December 2015, patients with an unruptured VBDA who underwent reconstructive EVT were enrolled in this study...

BACKGROUND: Subarachnoid hemorrhage (SAH) is a neurological emergency. Delayed ischemic neurological deficit is one of the main causes of poor outcome after SAH and is probably caused, at least in part, by cerebral vasospasm. The pathophysiology of this is multifaceted, but endothelial damage and activation as well as glycocalyx damage have been implicated. Prostacyclin has been shown to protect damaged and activated endothelium and to facilitate glycocalyx repair. We investigated biomarkers of endothelial activation and damage in patients with SAH randomized to 5 days prostacyclin infusion or placebo...

Azygous Vein Aneurysm (AVAs) is an uncommon cause of mediastinal mass. They are typically asymptomatic and do not commonly require treatment. They may mimic mediastinal adenopathy on chest radiographs. We present a case of AVAs found during evaluation of chest pain in a patient who was also found to have pulmonary thromboembolism. The mass was worked up with cross-sectional imaging techniques using both Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) and ultimately Positron Emission Tomography (PET)...
