Abstract

No definite conclusive management has been established in the treatment of thromboembolism during coil embolization of cerebral aneurysms. To date, intravenous heparin, intra-arterial fibrinolytic agent, and intravenous or intra-arterial glycoprotein IIb-IIIa inhibitors have been the mainstay of treatment. However, in practice, 2 major concerns may arise; first, recanalization is not always possible despite every effort of management; second, rehemorrhagic risk is increased if the event occurred during coiling of ruptured cerebral aneurysms. We introduce a new endovascular mechanical thrombectomy technique to overcome the aforementioned concerns. In 4 refractory cases involving conventional pharmaceutical treatment of thromboembolism during coiling, we practiced rescue suction thrombectomy using the reperfusion catheter of the Penumbra System. All 4 of the patients to whom this technique was applied were successfully recanalized; 2 were Thrombolysis In Cerebral Infarction scale of 2b and the other 2 were a scale of 3. Recanalization was confirmed at the follow-up angiography at least 12 hours after the procedure. No complication associated with this technique occurred. Forced-suction thrombectomy is a simple modification of the...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.
