Summary
Symptomatic arachnoid cysts in 12 patients were treated with cystoperitoneal shunts or membraectomy. Surgical interventions showed no recurrences, indicating effective management of these brain cysts.
Area of Science:
- Neurosurgery
- Pediatric Neurology
Background:
- Arachnoid cysts are congenital cerebrospinal fluid collections that can cause neurological symptoms.
- Symptomatic arachnoid cysts require timely diagnosis and effective treatment to prevent complications.
Observation:
- A cohort of 12 patients with symptomatic arachnoid cysts treated between 1983 and 1999 was analyzed.
- The mean patient age was 20.6 years, with the middle fossa being the most common location (10 cases).
- Initial CT scans revealed associated subdural hygroma in 7 patients and hydrocephalus in one.
Findings:
- Clinical presentations included increased intracranial pressure, cranio-megaly, and seizures.
- Treatment modalities included cystoperitoneal (CP) shunts, membraectomy, or a combination of both.
- Conservative management was attempted for two cases with hygroma evolving into hematoma, with one treated by irrigation and the other resolving spontaneously.
Implications:
- Surgical interventions, including CP shunts and membraectomy, demonstrated efficacy in treating symptomatic arachnoid cysts.
- No recurrences were observed during a mean follow-up of 3.6 years, suggesting long-term effectiveness.
- Potential complications such as subdural effusion, hematoma, intracranial hypotension, and shunt dependency were noted and managed.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.
