目的探讨微创钻颅联合血肿腔内应用氨苯甲酸治疗慢性硬膜下血肿的疗效。方法所有患者均根据颅脑CT扫描检查结果,以血肿最大层面为中心,在其后下方和前上方,分别钻直径3mm骨孔各一个,置入引流管,然后用0.4‰氨苯甲酸冲洗液经引流管注入,反复冲洗血肿腔,直至流出液体基本清亮后夹管2～4h后开放引流管持续引流,引流1～2d无引流液引出后,复查颅脑CT提示无血肿残留即拔除引流管。结果66例患者中,术后全部痊愈出院,无1例死亡,仅1例患者术中出血,随访1～3个月无1例血肿复发。结论微创钻颅联合血肿腔内应用氨苯甲酸的治疗慢性硬膜下血肿操作简单、手术时间短、创伤小、并发症少、疗效高、住院时间短、费用低廉等优点,值得临床推广应用。
Objective To investigate the curative effect of intraperitoneal injection of aminobenzoic acid in the treatment of chronic subdural hematoma with minimally invasive drilling cranial combined with hematoma. Methods All patients were based on brain CT scan results to the maximum level of hematoma as the center, followed in the bottom and the top of the former, respectively, a diameter of 3mm bone drilling holes, into the drainage tube, and then use 0.4 ‰ ammonia benzoate rinse After drainage tube injection, repeated flushing of the hematoma cavity, until the liquid is basically clear after 2 ~ 4h pinch tube open drainage continued drainage, drainage 1 ~ 2d no drainage lead to recheck brain CT prompts no hematoma residue removal of the drainage tube . Results Of the 66 patients, all were discharged after operation, none of them died. Only one patient had intraoperative bleeding. No recurrence of hematoma occurred in 1 to 3 months after follow-up. Conclusion Minimally invasive drilling combined intracranial hematoma with intravenous injection of ammonia benzoic acid treatment of chronic subdural hematoma is simple, short operation time, less trauma, fewer complications, high efficacy, short hospital stay, low cost, etc., worthy of clinical application .
