Abstract

Objective: To evaluate the safety and effectiveness of application of LVIS stent-assisted coiling endovascular procedures in cerebral aneurysms . Methods: The clinical data of 41 patients with intracranial aneurysms , which were performed in LVIS stent-assisted coiling endovascular therapies from June 2015 to October 2017 in The First Affiliated Hospital of Bengbu Medical College were analyzed retrospectively. 13 patients were unruptured and 28 patients were ruptured. Immediate angiography outcomes and follow-up angiography outcomes were assessed by DSA. Clinical outcomes were evaluated by modified Rankin Scale (mRS). Results: The LVIS stents were successfully delivered in 39 cases, however there were 2 cases in which the LVIS stents did not fully open.The technical success rate was 95.1%(39/41). There were 2 cases had complications during perioperation, the rate of complications was 4.9%(2/41). One was thrombus formation in operation, there was no nerve function defect.The other was infarction three days after operation and which had mild function defect(mRS grade 2). Raymond grade 1 was 31 cases, Grade 2 was 2 cases , grade 3 was 8 cases, the effective embolism rate was 80.5%(33/41). Mean follow up time was 14.4 months, 32 ca...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.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
