Abstract

Endovascular trapping is the preferred treatment method for a vertebral dissecting aneurysm. We describe a case of ruptured dissecting aneurysms located just proximal to the vertebrobasilar junction treated by trapping the dissecting segment and barricading the basilar artery with a stent to protect against coil protrusion. Modified parent artery trapping with a stent barricade allows preservation of the adjoining confluent zone or side branch during endovascular trapping of the vertebral dissection.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
