Abstract

Background. Although the concepts of «complex aneurysm» and «technically complex aneurysm» are widely used at present, there is no generally accepted definition. Moreover, the criteria are often subjective. Depending on the parameters included, complex aneurysms comprise 5-9.7% of all patients with cerebral aneurysms [1, 2]. Complex aneurysms have higher risk of complications, whose accurate assessment is difficult. In case of unruptured aneurysms, analysis of this risk is of particular importance.

Objective: To develop the microsurgical complexity index in the treatment of unruptured aneurysms for objective assessment of complexity of microsurgical treatment and prediction of complications.

Material and methods: The study included 850 patients with a single unruptured aneurysm who underwent microsurgical treatment. Postoperative outcomes and incidence of various complications were analyzed depending on anatomical and morphological characteristics of aneurysm.

Results: We developed the microsurgical complexity index for the treatment of unruptured aneurysms and appropriate web application (www.isam.rf). Patients with severe neurological disorders at discharge comprised 2.5%, and mortality rate was 0.47%. New neurological deficit after surgery occurred in 9.3% of cases. Moderate and severe in-hospital complications occurred in 8.6% of cases. Non-radical exclusion of aneurysm was observed in 4.1% of cases. In case of complexity index «0», the incidence of various complications was lower compared to the group as a whole by 1.8-5.7%, index «1» - by 0.1-2.7%, index «2». The incidence of in-hospital complications Clavien-Dindo grade III-V was lower by 0.3%. The incidence of functional status mRS score 4-6 did not differ from the group as a whole, and the incidence of other complications was higher by 0.9-3.6%. In case of complexity index «3», the incidence of all complications was higher by 0.6-12.8%, index «4» - by 10.8-22.6%, index «5-6» - by 3.9-22.7%.

Conclusion: Original index may be valuable for more objective assessment of the risks of microsurgical treatment of aneurysms depending on anatomical and morphological characteristics and stratification of aneurysms according to their complexity. Aneurysms with index ≥3 may be classified as a group of complex aneurysms.

[未破裂脑动脉瘤显微外科治疗复杂性指数]。
背景。虽然目前“复杂动脉瘤”和“技术上复杂动脉瘤”的概念被广泛使用,但没有一个普遍接受的定义。此外,这些标准往往是主观的。根据参数的不同,复杂动脉瘤占所有脑动脉瘤患者的5-9.7%[1,2]。复杂动脉瘤有较高的并发症风险,难以准确评估。在未破裂动脉瘤的情况下,分析这种风险是特别重要的。目的:建立显微外科治疗未破裂动脉瘤复杂性指数,以客观评价显微外科治疗的复杂性,预测并发症的发生。材料和方法:该研究包括850例接受显微手术治疗的单个未破裂动脉瘤患者。根据动脉瘤的解剖形态特点,分析其术后结局及各种并发症的发生率。结果:我们建立了治疗未破裂动脉瘤的显微外科复杂性指数和适当的web应用(www.isam.rf)。出院时出现严重神经障碍的患者占2.5%,死亡率为0.47%。9.3%的病例术后出现新的神经功能缺损。中重度院内并发症发生率为8.6%。非根治性动脉瘤排除率为4.1%。在复杂性指数为“0”的情况下,各种并发症的发生率比整个组低1.8-5.7%,指数为“1”- 0.1-2.7%,指数为“2”。院内并发症Clavien-Dindo III-V级发生率降低0.3%。功能状态mRS评分4-6的发生率与对照组整体无差异,其他并发症发生率高0.9-3.6%。在复杂性指数为“3”的情况下,所有并发症的发生率高0.6-12.8%,指数为“4”的发生率高10.8-22.6%,指数为“5-6”的发生率高3.9-22.7%。结论:根据动脉瘤的解剖形态特征和复杂程度对动脉瘤进行分层,原创性指标可更客观地评价显微手术治疗的风险。指数≥3的动脉瘤可归为一组复杂动脉瘤。
