The likelihood of rupture of unruptured intracranial aneurysms that were less than 10 mm in diameter was exceedingly low among patients in group 1 and was substantially higher among those in group 2. The risk of morbidity and mortality related to surgery greatly exceeded the 7.5-year risk of rupture among patients in group 1 with unruptured intracranial aneurysms smaller than 10 mm in diameter.
This study records the incidence and timing of postoperative hematomas in neurosurgical patients and analyzes the best use of neurosurgical intensive care. In 2305 patients undergoing freehand or stereotactic biopsy, elective or emergency craniotomy, or posterior fossa surgery, 50 (2.2%) developed a hematoma. Clinical deterioration as a result of postoperative hematoma occurred within 6 hours of surgery in 44 patients and more than 24 hours after surgery in six patients. Although patients undergoing posterior fossa surgery or emergency craniotomy warrant longer periods of intensive-care observation, patients having elective supratentorial operations can safely be transferred to a neurosurgical ward for observation, provided they have regained their preoperative neurological status by 6 hours postsurgery.
✓ The authors report a case of anterior sacral meningocele associated with a rectal fistula in a patient who had presented 20 years earlier with bacterial meningitis. To their knowledge, this is the first case in which a rectal fistula developed due to an anterior sacral meningocele. The clinical presentation, diagnosis, and treatment of this uncommon lesion is discussed.
The objective of the study was to highlight the diagnostic challenge of this elusive rare disease. A retrospective study of non-tuberculous spinal epidural abscesses (SEA) was carried out in Southern General Hospital, Glasgow, University Hospital of Wales, Cardiff, and Morriston Hospital, Swansea, from 1990 to 2000. Thirty-nine patients, consisting of 20 females and 19 males, with an age range from 20 to 85 years (mean: 61.1) were identified. Thirty-eight had localized back/neck pain. Eighteen were apyrexial. Twenty-nine demonstrated neurological deficit. All patients had raised inflammatory markers and gadolinium-enhanced magnetic resonance imaging (MRI) was diagnostic in 34. The most commonly identified organism was Staphylococcus aureus. All underwent surgical decompression, of which 13 required stabilization. Three died, seven lacked sphincter control and nine had motor deficit at the end of 1 year. It was concluded that fever is not mandatory for the diagnosis of SEA. Patients with localized back/neck pain and raised inflammatory markers need urgent MRI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
