Traditionally ascending aortic lesions have been repaired in open fashion: stenotomy, cardiopulmonary bypass, with or without deep hypothermic circulatory arrest. However, a subsegment of patients are deemed too high risk for open intervention. In the advent of endovascular advancement, this subset of patients may be treated with the use of ...

When more abdominal aortic aneurysms are repaired by endovascular approaches,the post-operative endotension without endoleak increase along with the extended follow-up. An early detection of such endotension and a proper differentiation from endoleaks are particularly important for the treatment decision-making. This article reviews the mechanism,diagnosis,and management of endotension.

Intracranial dural arteriovenous fistulas (DAVFs) are abnormal arteriovenous communications within the dura locating near a major venous sinus and are supplied by pachymeningeal arteries. DAVFs represent 10-15% of all intracranial arteriovenous malformations. The natural history and clinical manifestations are determined by location of the DAVFs and their angioarchitecture. Aggressive DAVF ...

Direct carotid-cavernous fistulas (CCFs) secondary to a ruptured intracavernous carotid aneurysm (ICCA) are usually high-flow lesions. On very rare occasions, a ruptured ICCA may present as a low-flow CCF, which poses a diagnostic and therapeutic dilemma whether the aneurysm and the observed fistula are causally related. Herein, we describe a ...
