Gamma Knife Surgery (GKS) effectively treats brain cavernous malformations (CMs), controlling epilepsy and reducing rebleeding risks. Careful planning is crucial to minimize radiation complications for optimal outcomes.

Area of Science:

  • Neurosurgery
  • Radiosurgery
  • Neurology

Context:

  • Cavernous malformations (CMs) pose significant neurological risks, including epilepsy and hemorrhage.
  • Surgical intervention for CMs can be high-risk, necessitating alternative treatment modalities.

Purpose:

  • To evaluate the efficacy and safety of Gamma Knife Surgery (GKS) for treating brain cavernous malformations (CMs).
  • To assess GKS impact on epilepsy control and rebleeding rates in CM patients.

Summary:

  • Gamma Knife Surgery (GKS) was performed on 92 patients with 114 CMs between 1994-2001, with follow-up ranging from 2-8 years.
  • Epilepsy control was achieved in 83.7% of patients, with 27.9% seizure-free. Rebleeding occurred in 9.8% of cases, and radiation edema in 7.6%.
  • Pathological analysis revealed coagulation necrosis and vessel obliteration post-GKS.

Impact:

  • GKS is a feasible and effective treatment for small or surgically risky CMs, offering significant epilepsy control.
  • The study highlights the importance of optimal timing and dose planning to mitigate radiation-related complications.
  • GKS demonstrates potential in reducing CM rebleeding rates after a latency period, improving patient prognosis.
