Interesting Case of Anterior Communicating Artery Aneurysm Turns Out to Be a Ruptured Fenestrated A1 Segment Aneurysm With Concomitant Multiple Aneurysms: A Case Report and Literature Review.

The luminal separation of the vessel into two distinct, parallel channels that reunite distantly is known as fenestration. There is a correlation between the development of an aneurysm and the proximal portion of fenestration, although fenestrations are typically regarded as a variant of normal anatomy. We report an interesting case of an anterior communicating artery (a-comm) aneurysm, which turns out to be a ruptured fenestrated A1 segment aneurysm after digital subtraction angiography with concomitant multiple aneurysms treated by clipping along with case report and literature review.

Endovascular Management of Falcine Dural Arteriovenous Fistula-A Case Report and Review of Literature.

Cranial dural arteriovenous (AV) fistulas are abnormal connections between the branches of dural arteries to dural veins or venous sinuses. They are most frequently located at the transverse sinus and cavernous sinus. They can occur at every cranial dural sinus.

Atlantoaxial Instability with Persistent Second Intersegmental Artery.

Understanding the anatomy of the vertebral artery is essential while manipulating the craniovertebral joint during surgery. Its anomalous course in congenital atlantoaxial dislocation makes it more vulnerable to injury. Preoperative dedicated computed tomography (CT) angiography helps identify the artery's position and plan for surgical procedure.

Spontaneous Vertebral Artery Arteriovenous Fistula with Neurofibromatosis Type I and Its Management with Covered Stent.

Vertebro-vertebral fistulas (VVFs) are uncommon vascular pathology. It can be either primary (spontaneous) or secondary (iatrogenic or mechanical trauma). Spontaneous vertebral arteriovenous malformation is often associated with connective tissue disorders.
