Abstract

The optimal strategy for monitoring the stability of ruptured intracranial aneurysms following coil embolisation is unclear. The value of delayed follow-up angiography in detecting new recurrences or progression of residual lesions visualised on earlier angiographic studies was determined in the light of the increasing use of non-invasive imaging techniques such as time of flight magnetic resonance angiography (TOF-MRA) for the evaluation of intracranial aneurysm occlusion. Ninety-seven patients with 105 ruptured aneurysms treated with detachable coils in 2005 and 2006 were included. The presence of a residual neck or aneurysm was assessed on catheter angiograms performed at 6 months and 2 years using the Raymond criteria (Class I = completely occluded, class II = small residual neck, class III = aneurysm sac filling). At 6-month follow-up, 32% of class I aneurysms progressed to class II and 6% of these aneurysms required re-treatment. A further 2-year angiogram was obtained in 59 patients with 65 aneurysms. Ninety-six per cent of class I, 100% of the class II and class III aneurysms remained unchanged at 2 years compared to 6 months. In our series, most recurrences were apparent at 6-month follow-up. The vast majority of coile...Continue Reading

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.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
