1、破裂脑动脉瘤不同时机夹闭术后的颅内压监测研究破裂脑动脉瘤不同时机夹闭术后的颅内压监测研究 许雅纹 方文华 蔡嘉伟 摘要目的 探討破裂脑动脉瘤不同时机夹闭术后患者的颅内压(ICP)变化特点。方法 回顾性分析20XX年10月20XX年9月我院收治的满足纳入和排除标准的49例成人破裂脑动脉瘤患者的临床资料,按照动脉瘤夹闭手术时间分为早期(发病3 d)手术组(26例)和延迟(发病421 d)手术组(23例),两组均在术后行持续ICP监测及以ICP为导向的综合治疗。比较、分析两组患者术后ICP变化特点及其临床意义。以随访12个月的死亡率和改良Rankin量表(mRS)评分评价两组患者的预后。结果 两组患
2、者的影像学特征方面、预后情况比较,差异无统计学意义(P0.05)。早期手术组患者术后ICP总体平均值为(15.213.71)mmHg,高于延迟手术组的(14.124.13)mmHg,差异有统计学意义(P0.05)。结论 发病3 d内早期手术的破裂脑动脉瘤患者术后总体ICP高于延迟手术组。早期手术和延迟手术术后ICP均呈先增高而后下降的趋势,早期手术最高峰在第5天,而延迟手术术后第2天最高。两种手术时机术后患者的ICP在经过治疗后均能够下降至较低水平。这一规律有助于破裂脑动脉瘤术后ICP增高临床诊疗策略的制定。 关键词脑动脉瘤;蛛网膜下腔出血;颅内压监测;预后 Abstract Objectiv
3、e To explore the characteristics of intracranial pressure (ICP) in patients after ruptured cerebral aneurysms clipped at different timing. Methods The clinical data of 49 adult patients with ruptured cerebral aneurysm in our hospital who met the inclusion and exclusion criteria from October 20XX to
4、September 20XX were retrospectively analyzed. They were divided into the early surgery ( 3 days after onset) group (26 cases) and delayed surgery (4-21 days after onset) group (23 cases) according to the timing of clipping. The continuous ICP monitoring and ICP-oriented comprehensive treatment were
5、performed after surgery in both groups. The characteristics and clinical significance of postoperative ICP of patients in two groups were compared and analyzed. The prognosis of the patients in two groups was evaluated by mortality and modified Rankin scale (mRS) score at 12-month follow-up. Results
6、 There were no significant differences in imaging characteristics and prognosis between the two groups of patients (P0.05). The total average postoperative ICP of patients in the early surgery group was (15.213.71) mmHg, which was higher than that in the delayed surgery group for (14.124.13) mmHg, a
7、nd the difference was statistically significant (P0.05). Conclusion The total postoperative ICP of patients with ruptured cerebral aneurysm who have been operated within 3 days after onset is higher than that of delayed surgery. The postoperative ICP of patients with either early or delayed surgery
8、shows a tendency of increasing first and decreasing then. The ICP reaches the peak on the fifth day after early surgery while that on the second day after delayed surgery. The ICP of patients after clipping at different timing can be reduced to a lower level after treatment. This feature may be help

10、aSAH)的诊疗技术已获得较大进步,但在全世界范围内其病死率和致残率仍然居高不下,其不良预后与全脑水肿、颅内压(intracranial pressure,ICP)增高、脑血管痉挛、迟发性脑梗死、全身系统并发症等因素密切相关1-2。由于医疗条件、水平和理念的差异,不同医院对破裂脑动脉瘤行夹闭或介入治疗的时机选择各不相同,其中对术后ICP增高、脑肿胀等继发脑损害和不良预后的疑虑则是影响手术时机判断的重要因素。有研究指出,aSAH患者存在ICP增高现象,ICP增高的控制是破裂脑动脉瘤临床治疗过程中的重要环节3。但对于破裂脑动脉瘤行开颅夹闭手术患者术后ICP变化的特点和规律则较少有文献,因此,本研究
11、旨在分析不同时机夹闭手术患者的ICP变化特点,为临床诊疗提供参考,现报道如下。 1资料与方法 1.1一般资料 选取20XX年10月20XX年9月我院共收治的467例自发性蛛网膜下腔出血患者,其中部分患者根据神经外科重症管理专家共识4行有创ICP监测,并从中进行研究对象的筛选,同时满足纳入和排除标准的患者49例,对其临床资料进行回顾性分析。纳入标准5:CT显示蛛网膜下腔出血,且CT血管造影术(CTA)或数字减影血管造影(digital subtraction angiography,DSA)确诊为脑动脉瘤;年龄18岁;Hunt-Hess分级级;经专业组讨论适合行开颅夹闭手术治疗;发病到手术时间2
12、1 d;持续有创ICP监测时间24 h。排除标准:未破裂脑动脉瘤;严重肝、肾衰竭或凝血功能障碍;患者及家属拒绝行夹闭手术或ICP传感器置入。按动脉瘤夹闭手术距离发病后的时间,将患者分为早期(发病3 d)手术组和延迟(发病421 d)手术组。早期手术组患者26例,平均年龄(56.8012.40)岁。延迟手术组患者23例,平均年龄(55.809.40)岁。两组患者年龄、性别、高血压、糖尿病、Hunt-Hess分级、改良Fisher分级、动脉瘤数量、术前脑积水等一般资料比较,差异无统计学意義(P0.05)(表1),具有可比性。本研究经我院医学伦理委员会审核及同意,患者及家属均知晓治疗情况并签署知情同
