Summary
Early age, pontine location, favorable preoperative status, and prompt surgery predict better outcomes for brainstem cavernous malformations (CM). Long-term results depend on CM location, size, and preoperative Modified Rankin Scale (mRS) score.
Area of Science:
- Neurosurgery
- Neurology
- Vascular Malformations
Background:
- Brainstem cavernous malformations (CM) present significant surgical challenges.
- Operability, complications, and outcomes are often unpredictable.
Purpose of the Study:
- To identify clinical parameters predicting outcomes in brainstem CM.
- To summarize the center's experience in treating brainstem CM.
Main Methods:
- Retrospective review of 59 patients with brainstem CM (2000-2012).
- Surgical resection was attempted in 54 patients, achieving complete resection in 58/59.
- Neurological status assessed using the modified Rankin scale (mRS); outcomes dichotomized as favorable (mRS 0-2) or unfavorable (mRS 3-6).
Main Results:
- Early age at presentation, favorable preoperative mRS, pontine CM location, and early surgical treatment predicted favorable outcomes.
- Small CM size (<10 mm) was associated with favorable long-term outcomes.
- Preoperative mRS and CM location were predictors of good long-term surgical outcomes.
Conclusions:
- Favorable surgical outcomes for brainstem CM are predicted by early presentation, pontine location, good preoperative mRS, and early intervention.
- Long-term outcomes are influenced by CM location, size, and preoperative mRS.
