Abstract

The combination of coils and Onyx for the treatment of carotid-cavernous fistulas (CCFs) is an interesting new development. The purpose of the current study is to evaluate our preliminary experience with the combined use of coils and Onyx for the treatment of traumatic CCFs. Between April 2009 and July 2014, 16 patients with 17 traumatic CCFs were embolized with the so-called 'armored concrete' treatment modality using coils, Onyx-18, and a non-detachable balloon via the transarterial approach. The outcomes were assessed both clinically and radiologically. Digital subtraction angiography (DSA) follow-up was performed 3 or 6 months after endovascular treatment while clinical follow-up was continued until December 2014. Obliteration of the CCFs was obtained with patency of the parent artery in all 16 cases. Follow-up DSA demonstrated stable occlusion of all the fistulas. Symptoms related to the CCFs were either resolved immediately or gradually over 2 months. No worsening of the cranial neuropathies was observed during the follow-up period which averaged 32.6 months. The 'armored concrete' treatment modality using coils, Onyx, and a non-detachable balloon promises to be a safe, economical, and effective alternative in the managem...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.
