Introduction:
Cavernous malformations are vascular malformations of the central nervous system formed by a group of capillaries not covered by pia mater and communicated to the vascular system at very low pressure with very slow flow. Surgery or radiosurgery are the treatment modalities.
Aims:
To analyze our results after surgical treatment of supratentorial cavernous malformations, reviewing clinical presentation, surgical indications and postoperative complications.
Patients And Methods:
Analytical retrospective study of medical records and images of patients who underwent resection of supratentorial cavernomas at FLENI from January 1996 until December 2013.
Results:
We evaluated 51 patients, mean age 34 years, followed for an average of 30 months. In 1.96% of patients diagnosis was incidental, the rest all presented symptoms. Bleeding at diagnosis was observed in 23.52%. Total excision of supratentorial cavernous malformations was possible in all cases. The only postoperative complication was one case of meningitis.
Conclusions:
The bleeding rate of supratentorial cavernous malformations in our series was 1.38% per patient per year. Surgical treatment effectively eliminated, or at least reduced symptoms, prevented rebleeding, and decreased need for antiepileptic drug therapy. Surgery have a low complication rate and good outcome.
