Dural arteriovenous fistulas (DAVF) of the cavernous sinus most commonly present with ocular symptoms and can be observed or treated with endovascular approaches, surgery, or radiosurgery. Combined surgical-endovascular approaches have been used for fistulas that are not amenable to standard endovascular approaches. A 40-year-old man presented with ocular symptoms from a cavernous sinus DAVF. ⋯ Subsequently he underwent coiling and onyx embolization of the DAVF. The intervention resulted in effective obliteration of the fistula. If a cavernous sinus DAVF is refractory to treatment, surgical exposure and cannulation of a cortical draining vein can facilitate transvenous endovascular treatments.

Aneurysms of the distal part of the anterior-inferior cerebellar artery (AICA) are rare, with an incidence of 0.1% to 0.5%. We report a 55-year-old woman suffering from a subarachnoid hemorrhage resulting from a ruptured intrameatal aneurysm of the AICA. ⋯ Follow-up angiography demonstrated exclusion of the aneurysm, confirming preservation of the distal AICA. We review the pertinent literature and discuss clinical presentation, radiological findings and surgical management of this patient.

Medulloblastoma is the most common malignant brain tumor in children. Post-surgical craniospinal irradiation (CSI; 30-36 Gy) plus local boost radiation therapy (RT; 54-56 Gy) is a standard treatment for children with medulloblastoma who are over 3 years old, resulting in a 5-year overall survival (OS) rate of 46% to 65% in average-risk patients and 50% in high-risk patients. The addition of chemotherapy has the benefit of reducing complications from radiation and improving the OS rate. ⋯ In the high-risk group the 5-year PFS rate was 48.9% ± 13% and the 5-year OS rate was 49.7% ± 13%. In the average-risk group, patients who received CSI of either 24 Gy (n=20) or 36 Gy (n=9) showed no difference in their 5-year PFS and OS rates. We found that patients who were ≤ 10 years old and patients who were female had a significantly better 5-year PFS rate.

Complex shifts in demography combined with drastic advancements in spinal surgery have led to a steep increase in often expensive spinal interventions in older and obese patients. A cost analysis, based on hospital charges, was performed retrospectively on the spinal surgery of 787 randomly selected patients who were operated at The Medical Center of Central Georgia, a large urban hospital in Central Georgia. The types of surgery included anterior cervical decompression and fusion (ACDF), lumbar decompression and fusion (LDF), and lumbar microdiscectomy (LMD). ⋯ The increments in cost of spinal surgery in relation to age especially and BMI were, nevertheless, small. We believe that spinal surgery in the elderly should be viewed as a public investment, as the modern concept of retirement involves people working intermittently up to their 80s. Thus, where clinical research on medical costs is to be conducted, cost analysis needs to be expanded to include returns to government in the form of taxes.
