Abstract

OBJECTIVE: The Brazilian public health system determines a quantity of coils allowed to treat a cerebral aneurysm. The goal of this paper was to determine the number of coils necessary to treat an aneurysm based on size. METHODS: All patients harboring an aneurysm treated by endovascular approach between 1999 and 2003 were reviewed. RESULTS: There were 952 aneurysms included. Mean diameter sac was 8.2 mm with 7.9 coils per aneurysm. Out of 462 small aneurysms, mean size was 4.8 mm, with 4.6 coils/aneurysm used. A total of 315 medium aneurysms were treated, mean size was 8.6 mm, with 8.2 coils. Out of 135 large, mean size was 17 mm, with 16.1 coils. Forty giant aneurysms were treated with a mean size of 32 mm and 28.7 coils. CONCLUSIONS: We propose size as a reference to predict the number of coils necessary to treat each aneurysm: one coil for each millimeter of diameter.

Abstract

Primary central nervous system lymphoma (PCNSL) is a form of extranodal non-Hodgkin’s lymphoma, which occurs in the brain, leptomeninges, spinal cord, or eyes. PCNSL is an uncommon intracranial neoplasm, particularly in the immunocompetent patient population. An immunosuppressive state is the unique established risk factor for PCNSL, and the HIV-related primary lymphoma is 3600-fold more common compared with the general population. This tumor constitutes 0.3–1.5% of all intracranial neoplasm in patients without AIDS1 […] Primary central nervous system lymphoma in an [...]
