| Popis: | Objective. To analyze the outcomes of posterior approach in the surgery of intradural extramedullary meningiomas located ventrally and dorsally in relation to the spinal cord denticulate ligaments. Material and Methods. The study included 29 patients with spinal intradural meningiomas operated on using posterior approach. Patients were divided depending on the tumor location relative to the denticulate ligaments into ventral (n = 13) and dorsal (n = 16) groups. The surgery duration, the degree of tumor resection, clinical outcomes, the presence and nature of complications, and the frequency of recurrence were assessed. Results. The average follow-up period was 29 (6 to 61) months. Total tumor removal was performed in 93.1 % of cases: 11 cases (84.6 %) in ventral group and 16 cases (100.0 %) in dorsal group. The average duration of surgery was 136 minutes for dorsal meningiomas and 181 minutes for ventral meningiomas (p < 0.05). Complications in the form of CSF leakage were registered in two patients (6.9 %). In 11 (84.6 %) patients with ventral meningiomas and 15 (93.7 %) patients with dorsal meningiomas, an improvement or preservation of neurological functions at the pre-surgery level was observed. Recurrences were observed in two patients (6.9 %). Conclusion. Patients with spinal meningiomas have a favorable neurological outcome and a low recurrence rate. Surgery is more complicated in patients with ventral meningiomas. In most cases, unilateral posterior approach is applicable for both ventral and dorsal meningiomas. |
