Case ReportsMyelopathy due to intracranial dural arteriovenous fistula: a potential diagnostic pitfall. Case report.
Intracranial dural arteriovenous fistula (DAVF) is rare and potentially life-threatening disease often presenting as vascular myelopathy. The early and proper diagnosis is challenging because the clinical manifestations are related to the distribution of the draining vein, not the fistula site, and imaging findings are similar to demyelinating disease of the spinal cord. ⋯ These symptoms were highly suspicious for transverse myelitis but were caused by an intracranial DAVF. Intracranial DAVF with venous reflux to the brainstem and spinal cord is a rare but important differential diagnosis of progressive worsening myelopathy that is treatment resistant and gives the diagnostic impression of transverse myelitis.

Factors involved in maintaining prolonged functional independence following supratentorial glioblastoma resection. Clinical article.
The median survival duration for patients with glioblastoma is approximately 12 months. Maximizing quality of life (QOL) for patients with glioblastoma is a priority. An important, yet understudied, QOL component is functional independence. The aims of this study were to evaluate functional outcomes over time for patients with glioblastoma, as well as identify factors associated with prolonged functional independence. ⋯ The identification and consideration of these factors associated with prolonged functional outcome (preoperative KPS score ≥ 90, seizures, primary glioblastoma, gross-total resection, temozolomide) and decreased functional outcome (older age, coronary artery disease, new postoperative motor deficit) may help guide treatment strategies aimed at improving QOL for patients with glioblastoma.

Functional mapping-guided resection of low-grade gliomas in eloquent areas of the brain: improvement of long-term survival. Clinical article.
Low-grade gliomas (LGGs) frequently infiltrate highly functional or "eloquent" brain areas. Given the lack of long-term survival data, the prognostic significance of eloquent brain tumor location and the role of functional mapping during resective surgery in presumed eloquent brain regions are unknown. ⋯ Presumed eloquent location of LGGs is an important but modifiable risk factor predicting disease progression and death. Delineation of true functional and nonfunctional areas by intraoperative mapping in high-risk patients to maximize tumor resection can dramatically improve long-term survival.

Sixteen-year single-surgeon experience with coil embolization for ruptured intracranial aneurysms: recurrence rates and incidence of late rebleeding. Clinical article.
Over a 16-year period, 570 patients presenting with acute aneurysmal subarachnoid hemorrhage were successfully treated using endosaccular coil embolization within 30 days of hemorrhage by a single surgeon. Patients were followed to assess the stability of aneurysm occlusion and its longer-term efficacy in protecting against rebleeding. ⋯ Periodic follow-up with angiographic studies after coil embolization is recommended to identify aneurysm recurrence and patients at a high risk of late rebleeding in the medium term. More frequent follow-up is recommended for patients harboring coincidental unruptured aneurysms.
