Abstract

Unexplained post-procedural events such as cerebral edema, inflammation, aseptic meningitis and hydrocephalus have been reported following unruptured cerebral aneurysm coiling. However, understanding of the etiology for these occurrences is limited due to their rare occurrence. A multicenter registry was developed to investigate further the occurrence of these events. This registry consisted of a retrospective analysis of unruptured aneurysms treated with hydrocoil that evolved to develop focal cerebral edema, inflammation, aseptic meningitis, or ventricular enlargement/hydrocephalus following uncomplicated coil embolization. Data points included pre, intra, and postoperative imaging, patient demographics, aneurysm demographics, procedural details such as coils used, medications administered, and intraprocedural complications, and all post-procedure follow-up including clinical status of the patients and all adverse events. Twenty-five patients (26 aneurysm coiling procedures) were found at 12 centers over an 8-year period. The mean aneurysm size was 13.7 mm. The average time from treatment to onset of symptoms was 8.5 months (2 weeks to 30 months, median 6 months). Delayed hydrocephalus was the most common clinical presentatio...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.

Aneurysm

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

Cardiomegaly

Cardiomegaly, known as an enlarged heart, is a multifactorial disease with different pathophysiological mechanisms. Hypertension, pregnancy, exercise-induced and idiopathic causes are some mechanisms of cardiomegaly. Discover the latest research of cardiomegaly here.
