侧方人路半椎板切除治疗脊髓哑铃形肿瘤和脊髓腹侧肿瘤(附35例报告)

本文报告测方入路半椎板切除治疗脊髓肿瘤35例,包括颈段17例,胸段14例,腰段4例;哑铃形神经鞘瘤24例,脊膜瘤8例,脊髓内肿瘤2例,脊索瘤1例。术前均有神经功能缺失。本入路适用于巨大、复发性哑铃形肿瘤,脊髓腹侧肿瘤。肿瘤根治率高,住院时间短,术后脊柱畸形发生少为其优点,术中尽可能采用显微外科技术及高速电钻。

The Lateral Hemilaminectomy Approach for Spinal Dumbbell Tumors and Tumors Ventral to the Spinal Cord

Thirty-five patients with spinal tumors, including 24 dumbbell neurilemomas, 8 meningiomas, 2 intramedullary astrocytomas and one chordma, were operated on via the lateral hemilaminectomy-approach. The tumors were located at the cervical segment in 17 patients, thoracic in 14 and lumbar in 4. Thirty-two tumors were removed totally and 3 subtotally without mortality and neural deficits. The operative techniques were described in detail. The lateral hemilaminectomy approach is useful for huge reccurrent spinal dumbbell tumors & tumors ventral to the spinal cord. This approach has the following advantages: (a) The tumor can be radically removed. (b) The postoperative spinal malformations can be avoided. During operation the microsurgical techniques & high-speed drill are recommended.
