Cerebral vasospasm (CV) remains a major cause of mortality and morbidity in patients with subarachnoid hemorrhage (SAH). Here, we examined the effectiveness and safety of intra-arterial injection of colforsin daropate hydrochloride (CDH). A consecutive series of 29 patients with angiographically confirmed CV received intra-arterial CDH (IAC) therapy. Angiographic changes in ...

An ideal animal model of abdominal aortic aneurysm (AAA) is of great importance for clarifying unknown complex mechanisms of the pathogenesis. We introduce a new, simple technique to create reliable AAAs that simulate human aneurysms. Experimental models of AAAs were created in 71 rats by means of a 20-minute application ...

Endovascular aneurysm repair (EVAR) is commonly used as a minimally invasive technique for repairing infrarenal aortic aneurysms. There have been recent concerns that a subset of high-risk patients experience unfavorable outcomes with this intervention. To determine whether such a high-risk cohort exists and to identify the characteristics of these patients, ...
