Arteriovenous malformations (AVMs) are tortuous vessels characterized by arteriovenous (AV) shunts, which displace capillaries and shunt blood directly from artery to vein. Notch signaling regulates embryonic AV specification by promoting arterial, as opposed to venous, endothelial cell (EC) fate. To understand the essential role of endothelial Notch signaling in postnatal ...

Endovascular embolization is the primary therapeutic modality for intracranial dural arteriovenous fistulae. Based on access route, endovascular treatment can be schematically divided into transarterial, transvenous, combined, and direct/percutaneous approaches. Choice of access route and technique depends primarily on dural arteriovenous fistulae angioarchitecture, pattern of venous drainage, clinical presentation, and location. ...

Endovascular treatment of aneurysms with coils is based on the assumption that dense packing leads to intra-aneurysmal flow reduction with subsequent thrombosis and occlusion. Despite significant advances in technology, anatomic results remain suboptimal with residual and recurrent aneurysms being a drawback of the coiling procedure. In this report we describe ...

Multiple studies have shown, retrospectively, the inverse relationship between packing density and aneurysm recurrence. Furthermore, it has been shown that prospectively measuring the packing density, by carefully selecting the first coil with the highest resultant initial packing density, yields higher packing densities overall. It is our theory that prospectively measuring ...
