Abstract

The aim of this study was to investigate the role of Von Willebrand Factor/thrombospondin type I repeats-13 (VWF/ADAMTS13) balance in aSAH. Fifty eight patients with aSAH at the First Affiliated hospital of Soochow University, Suzhou, China, between January 2012 and January 2014 were eligible for the study. They were divided into delayed cerebral ischemia group (DCI group) and non-delayed cerebral ischemia group (no DCI group), or cerebral vasospasm group (CVS group) and no spasm group (no CVS group), or good outcome group and poor outcome group. The control group consisted of twenty healthy people. All patients underwent CT, DSA, or (and) CTA diagnosed with intracranial subarachnoid hemorrhage which is caused by aneurysm rupture. Venous blood was drawn in tubes at 3 time points: 1 day after SAH (T1), (4±1) days after SAH (T2), and (9±1) days after SAH (T3) to determine plasma concentrations of ADAMTS13, VWF, P-selectin and IL-6 via enzyme-linked immunosorbent assay (ELISA). Transcranial doppler sonography (TCD) was used to measure mean blood flow velocity of the middle cerebral artery (VMCA). Glasgow Outcome Scale (GOS) was measured before discharge. Among 58 patients, 12 (20.7%) had DCI, 40 (68.9%) had TCD evidence of CVS, an...Continue Reading

Brain Ischemia

Brain ischemia is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. Discover the latest research on brain ischemia here.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
