摘      要：OBJECTIVE To analyze our management strategy and results of treating patients affected by meningiomas invading the sagittal or transverse sinuses. METHOOS Review of data from 35 patients with pathologically confirmed meningiomas（29 of the sagittal sinus and 6 of the transverse sinus） surgically treated between from July 1999 and June 2003, including clinical manifestations, mode of diagnosis and curative effect of microsurgery etc. For our surgical decision-making, meningiomas were classified into six types based on the degree of sinus involvement. RESULTS A Simpson＇s Grade Ⅰ resection was achieved in 27 cases （77.1%）, Grade Ⅱ in 6 （17.1%） and Grade Ⅲ in 2 （5.7%）. No patients died after the operations. The recurrence rate in the study overall was 2.9%, with a follow-up period from 3 to 6 years. CONCLUSION Application of microsurgical techniques, protection of the sinus, avoidance of damages to the cerebral cortex, veins of the central sulcus, as well as other veins from the tumor, are the major factors for increasing the rate of total resection, reducing complications and improving the quality of life for the patients with meningiomas invading the sagittal or transverse sinuses.
