The incidence rate of aneurysmal subarachnoid hemorrhage (SAH) in the elderly is increasing. Although endovascular coiling has become a major form of treatment for SAH in elderly patients, not all ruptured aneurysms can be managed with an endovascular approach. Conventional surgical clipping still plays an important role in SAH treatment. ...

Recanalization of arterial obstruction is associated with improved clinical outcomes. There are no controlled data demonstrating whether arterial obstruction status predicts the treatment effect of intravenous (IV) tissue plasminogen activator (tPA). We aimed to determine if the presence of arterial obstruction improves the treatment effect of IV tPA over placebo ...

YC-1 (3-(5'-hydroxymethyl-2'furyl)-1-benzyl-indazole) is an allosteric activator of soluble guanylyl cyclase (sGC) and a vasodilator. This study describes a paradoxical action of YC-1 in isolated vessels of patients with coronary artery disease (CAD) that appears to trigger an endothelium-dependent vasoconstrictor pathway present in vessels with endothelial dysfunction. Effects of YC-1 on ...

At present, revascularization is still one of the most critical technologies in orthotopic liver transplantation (OLT). Hepatic artery (HA) variations occur frequently in both donors and recipients. Moreover, there are always some pathological changes in the recipient hepatic artery. If handled improperly, it may cause complications after anastomosis. Therefore, arterial ...
