Abstract

The dual microcatheter technique is an alternative treatment for stent-assisted coiling in acutely ruptured wide-necked aneurysms because of no antiplatelet therapy. We assessed the safety and efficacy of this technique in ruptured wide-necked aneurysms. Between March 2008 and March 2016, 56 acutely ruptured aneurysms were treated with the dual microcatheter technique. The angiographic results, treatment-related complications, and clinical outcome were documented. Angiographic follow-up was available in 37 patients at a mean of 20.6 months (6 to 81 months). On the postembolization angiograms, 27 (48.2%) aneurysms showed complete occlusion (Raymond 1), 15 (26.8%) showed neck remnant (Raymond 2), and 14 (25.0%) showed body remnant (Raymond 3). Treatment-related complications occurred in seven patients (12.5%) and six patients remained asymptomatic. The permanent complication rate was 1.8% (1/56). A good outcome (modified Rankin Scale (mRS) score, 0-2) was observed in 64.3% of patients at the time of discharge. Five patients had died, all of the sequelae of subarachnoid hemorrhage. The overall mortality rate was 8.9% (5/56); however, the treatment-related mortality rate was 0%. Of the 37 aneurysms for which angiographic follow-up ...Continue Reading

Aneurysm

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

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.
