烟雾病间接血管重建术后脑内钙化分析

目的：分析烟雾病术后患者脑内钙化的特点及形成机制。方法：选取我院2004年11月至2005年11月手术后复查CT扫描的烟雾病患者28例，年龄4～46岁，中位年龄17岁。男女比例为1：1。手术至CT检查最短间隔为1～90d，中位时间7d。结果：本组烟雾病间接血管重建术患者中4例出现脑内钙化，发生率为14．3％（4／28），其中3例钙化发生在脑出血患者中，占5例脑内出血患者的60％（3／5），且钙化与出血部位一致。结论：烟雾病间接血管吻合术后患者脑内出血与钙化灶形成关系密切，可能是钙化形成诱导因素所致。

Analysis of encephalic calcification after indirect revascularization in moyamoya disease

Objective： To analyze the characters and mechanism of intracerebral calcification in moyamoya disease after operation. Methods： The clinical data of ：28 patients aged 4-46 （average= 17） with moyamoya disease receiving CT scanning after operation in our hospital were retrospectively analyzed. The shortest time is 1 to 90 days between CT exam and operation （median 7days）. Results： 4 cases（14.3%, 4/28） had intracerebral calcification in indirect revascularization of moyamaya disease, and 3（60%） showed in patients（5cases） had intracerebral hemorrhage. The location of calcification was in accordance with the hemorrhage position. Conclusion： There is a close relationship between intracerebral hemorrhage and calcification in indirect revascularization of moyamaya disease. It might be the motivation of calcification formation.
