Fluoroscopically guided epidural blood patch with subsequent spinal CT scans in the treatment of spontaneous cerebrospinal fluid hypovolemia.
Recent evidence has indicated that the efficacy of the epidural blood patch (EBP) in the treatment of spontaneous CSF hypovolemia (SCH) is still limited. Therefore, further improvement of the EBP technique is an important clinical challenge. The authors describe a series of cases of SCH treated with fluoroscopically guided placement of an EBP and followed up with subsequent spinal CT scans. ⋯ The results indicated that fluoroscopically guided EBP and subsequent spinal CT scans may provide a highly effective therapy in patients with SCH proven on CT myelography studies.

Geographic variation and regional trends in adoption of endovascular techniques for cerebral aneurysms.
Considerable evolution has occurred in treatment options for cerebral aneurysms. Development of endovascular techniques has produced a significant change in the treatment of ruptured and unruptured intracranial aneurysms. Adoption of endovascular techniques and increasing numbers of patients undergoing endovascular treatment may affect health care expenditures. Geographic assessment of growth in endovascular procedures has not been assessed. ⋯ The NIS database reveals a significant increase in the use of endovascular techniques, with the majority of both ruptured and unruptured aneurysms treated endovascularly by 2008. Differences in hospital costs between open and endovascular techniques are likely secondary to patient and site-of-service factors. Presentation with SAH was the primary factor affecting hospital cost and a greater percentage of endovascular procedures completed at urban academic medical centers. There is substantial regional variation in the adoption of endovascular techniques.

Multicenter StudyRebleeding risk after treatment of ruptured intracranial aneurysms.
Postprocedural rebleeding is a significant source of morbidity following endovascular treatment of ruptured intracranial aneurysms. Previous large-scale reports include the Cerebral Aneurysm Rerupture After Treatment trial, the International Subarachnoid Aneurysm Trial, and the study on Early Rebleeding after Coiling of Ruptured Cerebral Aneurysms, which reported nonprocedural rebleeding rates within 30 days of treatment of 2.7%, 1.9%, and 1.4%, respectively. However, coiling of intracranial aneurysms is in a state of continual change due to advancing device design and evolving techniques. These studies included only patients initially treated prior to 2004. In the present study the authors assess the most recent short-term results with endovascular treatment of ruptured aneurysms. ⋯ Recent data suggest that the periprocedural rebleeding rate may be improving over time.

Biography Historical ArticleCushing and the treatment of brain wounds during World War I.
Harvey Cushing, perhaps the most important founder of American neurosurgery, was an Army neurosurgeon in France from 1917 to 1918. Over a 3-month period in 1917 he and his team operated on 133 soldiers with a brain wound. The operative mortality rate for their last 45 patients was 29%, considerably lower than the usual postoperative mortality rate of approximately 50% for those with a brain wound. ⋯ As the decades passed he was eventually credited as the "originator of brain wound care." This report shows that these attributions are misplaced. Cushing merely followed the enlightened surgical precepts of the time developed by Continental (European) surgeons. It also examines Cushing's writings to ascertain how these misperceptions concerning his originality might have been generated.

Endoscopic endonasal skull base surgery: analysis of complications in the authors' initial 800 patients.
The development of endoscopic endonasal approaches, albeit in the early stages, represents part of the continuous evolution of skull base surgery. During this early period, it is important to determine the safety of these approaches by analyzing surgical complications to identify and eliminate their causes. ⋯ Endoscopic endonasal skull base surgery provides a viable median corridor based on anatomical landmarks and is customized according to the specific pathological process. This corridor should be considered as the sole access or may be combined with traditional approaches. With the incremental acquisition of skills and experience, endoscopic endonasal approaches have an acceptable safety profile in select patients presenting with various skull base pathologies.
