Abstract

To evaluate the feasibility and safety of endovascular treatment of ruptured and unruptured intracranial very small aneurysms (< or = 3 mm in maximal diameter). Forty-eight intracranial very small aneurysms in 44 patients treated with endovascular therapy from June 2001 to August 2009 were reviewed retrospectively in clinical, imaging, interventional and follow-up data. Among 44 patients, there were 20 males and 24 females with a mean age of 57.8 years old. The Hunt-Kosnik grade was as follows: Grade 0 (n = 11); Grades I & II (n = 23); Grades III & IV (n = 9); and ungraded (n = 1). The sizes of 48 aneurysms were not more than 3 mm in maximal diameter. The locations of aneurysms were as follows: ACoA (n = 11), MCA (n = 8), PCoA (n = 14), ICA (n = 12), pericallosal artery (n = 1), VA (n = 1) and PICA (n = 1). Thirty-nine aneurysms were embolized with coil, of which 13 with stent assistance and 6 by balloon remodeling technique. The other 9 aneurysms underwent sole stent placement in parent artery. Among 39 coiling aneurysms, 100% occlusion was achieved in 9 aneurysms, 90% in 20, 80% in 9 and less than 80% in 1 respectively. Only one aneurysm ruptured during coiling. Two patients had transient hemiparesis and one patient had ataxi...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.
