Surgery via sylvian fissure-insular approach for 8 patients with invasive thalamus cavernous malformations / 中华神经医学杂志

ABSTRACT

Objective:To investigate the surgical treatment efficacy and experience of invasive thalamus cavernous malformations (CMs).Methods:A retrospective analysis was performed. The clinical and follow-up data of 8 patients with invasive thalamus CMs, admitted to our hospital from July 2007 to June 2020, were chosen. These patients accepted minimally invasive resection via sylvian fissure-insular approach after the second rapture hemorrhage; follow up was performed for 8 months-10 years. Results:The lesions of these 8 patients were near the lateral thalamus, and the lesions were completely removed during the surgery. Within 24 h of surgery, the lower limb muscle strength of one patient was improved to grading 2, and that of 2 patients was improved to grading 1. Follow up results 6 months after treatment showed that the modified Rankin scale scores were 1-3 in 5 patients and 4 in 3 patients; and there were no recurrence during the follow-up of (49.7±37.8) months.Conclusion:The resection via sylvian fissure-insular approach is safe and effective for patients with invasive thalamus CMs after the second rapture hemorrhage.
