Abstract:
Objective:To investigate the clinical effacies of endoscopic midline and paramedian supracerebellar infratentorial (SCIT) approaches during resection of pineal tumors.Methods:The clinical data of 4 patients with pineal tumors resected via SCIT approach under neuroendoscope in our hospital from December 2017 to March 2019 were analyzed retrospectively. All patients underwent MR imaging plain and enhanced scans before operation. The tumors were resected via SCIT approach under general anesthesia in lateral subduction position (three were via paramedian SCIT approach and one was via midline SCIT approach). The patients were followed up for 3-12 months and the brain MR imaging was reexamined.Results:The tumors were completely resected in 4 patients. Two patients were confirmed to have mixed germ cell tumors, one was confirmed to have seminoma, and the other one was confirmed to have mature teratoma by postoperative pathology. One achieved good recovery after surgery. Two were treated with whole brain and spinal cord radiotherapy, the original lesion in one patient recurred 4 months after resection and systemic chemotherapy was given, and so far, no recurrence was noted; and the other one achieved good recovery. One did not receive chemoradiotherapy due to economic reasons and relapsed 4 months after surgery.Conclusion:It is safe and effective to resect the tumors in pineal region via midline and paramedian SCIT approaches with neuroendoscopy; the best approach should be selected according to the blood supply, size and location of the lesions.
