The surgical management of cerebral cavernous angiomas
Insights
Cavernous angiomas (CA), though once rare, now have a 0.9% prevalence. Surgical management is key for treating cerebral CA, reducing hemorrhage risk, and controlling seizures, with minimally invasive techniques improving outcomes.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Malformations
Background:
- Cavernous angiomas (CA) are hamartomatous hemorrhagic lesions.
- Improved neuroimaging and clinical awareness have increased CA diagnosis.
- Actual prevalence is recognized as 0.9%, not rare as previously thought.
Purpose of the Study:
- To report surgical management experience with cerebral cavernous angiomas.
- To suggest a classification system for CA based on surgical accessibility and morbidity.
- To highlight the role of surgery in managing CA complications.
Main Methods:
- Review of surgical cases of cerebral cavernous angiomas.
- Classification of lesions based on surgical factors.
- Analysis of outcomes related to surgical approach and lesion characteristics.
Main Results:
- CA are diagnosed between ages 20-50, with female predominance for bleeding and male for seizures.
- Multiple CAs can be asymptomatic, as confirmed by MR imaging.
- Surgery is the primary treatment for hemorrhage risk and seizure control.
Conclusions:
- Surgical intervention is crucial for managing cerebral cavernous angiomas.
- Minimally invasive surgical approaches reduce post-operative morbidity.
- A proposed classification aids in surgical planning and outcome prediction.
Abstract:
Cavernous angioma (CA) is a hamartomatous hemorrhagic lesion which has received a great deal of attention in recent years due to improvement of neuroimaging with magnetic resonance and heightened clinical awareness. Long considered to be rare, its actual prevalence is now recognized to be of 0.9%. Cavernous angiomas may be multiple, particularly in patients with familial form. It may be associated with a variety of clinical syndromes attributed to focal microhemorrhages or less frequently to gross bleeding. CA are usually diagnosed between the age of 20 and 50 with a highest clinical incidence in the fourth decade. A female predominance is observed in regard to bleeding. The male patients are more at risk for seizures. The recent series of MR imaging confirm that CA even when multiple can be asymptomatic in a significant number of cases. Surgery is the treatment of choice in order to eliminate the risk of hemorrhage and improve the control of seizures. Minimally invasive approaches are now adopted with reduced post-operative morbidity. We report our experience in surgical management of cerebral CA and suggest a classification of the lesions according to surgical accessibility and residual morbidity.
