目的：探讨脑出血行微创颅内血肿穿刺引流术（MIS）引流结束时（EOT）颅内残留血肿量对患者预后 的影响。方法：自发性脑出血患者256例纳入研究，以患者出院预后为标准，经ROC曲线分析后得到EOT 时颅内血肿残留量预测患者出院预后好的截断值为11.288 mL；据此将患者分EOT低残留组（EOT颅内血 肿残留量＜11.288 mL）191例和EOT高残留组（EOT颅内血肿残留量≥11.288 mL）55例。收集并比较2组 人口学资料、既往史、本次发病临床资料及影像学资料。结果：EOT低残留组较EOT高残留组的预后更 好、3个月死亡率更低、mRS评分更低，差异有统计学意义（均P＜0.05）；经二元Logistic回归及COX回归 结果提示EOT时颅内血肿残留<11.288 mL是患者出院预后好的独立预测因子。结论：脑出血患者MIS治 疗EOT时颅内血肿残留＜11.288 mL可能是患者出院预后好的独立预测因素。

To investigate the effect of residual hematoma volume at the end of treatment (EOT) on the prognosis of intracerebral haemorrhage (ICH) patients after minimally invasive surgery (MIS). Meth? ods: A total of 256 ICH patients treated with MIS were enrolled. According to the prognosis of the patients after discharge, the ROC curve analysis showed that the cut-off value of residual hematoma volume at EOT was 11.288 mL. 119 patients were divided into low EOT residual hematoma volume group (residual intracranial hematoma volume＜11.288 mL) and 65 in high EOT residual hematoma volume group (residual intracranial hematoma volume≥11.288 mL). The demographic data, past history, clinical data and imaging data of all the patients were collected and analyzed. Results: Compared with the high EOT residual hematoma volume group, the low EOT residual hematoma volume group had a higher proportion of good prognosis and a lower proportion of mortality rate. The results of binary logistic regression and COX regression showed that residual hematoma volume<11.288 mL at EOT was an independent predictor of good prognosis. Conclusion: The residual hematoma volume less than 11.288 mL at EOT may be an independent predictor of good prognosis for ICH patients after MIS.
