内囊前肢在立体定向手术中的应用与潜在风险

Lesion of Internal capsule anterior by stereotactic techniques and therapeutic potential risk

目的探讨内囊前肢靶点脑立体定向手术后可能出现的手术风险,采用积极预防措施,最低限度减少手术并发症,提高手术治疗效果。方法结合以往文献资料、内囊前肢靶点的解剖特点,分析内囊前肢靶点术后易出现的手术并发症。结果670例次内囊手术后(右侧350次,左侧320次)发生出血12例,发生率为1.79%,6例发生内囊区脑梗塞,发生率为0.9%,远期遗留右上肢偏瘫症状4例。结论内囊前肢靶点的解剖特点与手术存在一定风险。

Objective To explore therapeutic potential risk of Lesion of Internal capsule anterior limb by stereotactic techniques, to decrease the risk of operation treatment and to improve the effect of operation by use the positive measure. Methods Analysis the complication of Lesion of Internal capsule anterior limb combined the lit erature and the anatomic feature. Results There were 12 hemorrhages and 6 cerebral infarctions in 670 lesion of Internal capsule anterior limb （right 350, left 320）, the frequency of hemorrhage was 1.79%, the frequency of infarction was 0. 9%. There were 4 patients leaved over paralysis of upper limb. Conclusion There were potential risks on Lesion of Internal capsule anterior limb by stereotactic techniques.
