摘要
背景与目的:第四脑室肿瘤原发于第四脑室或自小脑蚓部突入第四脑室,易致脑干受压,手术切除有难度。本文探讨第四脑室肿瘤的显微手术治疗方法。方法:采用后颅窝正中入路,骨瓣或骨窗开颅,显微镜下切除肿瘤12例。结果:肿瘤全切9例,近全切除2例,大部切除1例。治愈10例,好转1例,1例死于继发性脑干损伤。结论:显微手术治疗第四脑室肿瘤,全切率高,可明显提高手术的成功率。
BACKGROUND ＆ OBJECTIVE： Fourth ventr/cular tumors originated from the fourth ventricle or cerebellum. The tumor often compresses the brain stem and were difficult to be resected totally. We reviewed the technique and results of microsurgical treatment of fourth ventrlcular tumor in this paper. METHODS： 12 cases of 4th ventricle tumor were resected by suboccipital median approach with bone flaps or bone window craniotomy. RESULTS： Among the 12 patients, 9 tumors were totally removed, 2 with subtotal removal and 1 with partially removal. Ten cases were cured with excellent clinical outcome, 2 cases improved, and 1 patient died from secondary brainstem injury. CONCLUSION： Using microsurgical technique the chance of total removal of 4th ventricle tumor is high. This technique help in improving the outcome of the patients.
