目的评估浅低温弓部阻断技术在DeBakey Ⅰ型主动脉夹层外科治疗中应用的安全性和有效性。
方法前瞻性纳入北京安贞医院自2019年12月至2023年11月期间行弓部阻断技术治疗的97例DeBakey Ⅰ型主动脉夹层患者。根据停循环期间最低直肠温,分为浅低温组和中低温组,比较两组患者围术期资料,以30天死亡、卒中、截瘫、连续性肾脏替代疗法组成的复合结局事件作为主要终点事件,采用多因素 logistic回归明确临床不良结局的影响因素,采用 Kaplan- Meier法评估两组患者远期生存率,分析浅低温弓部阻断技术在DeBakey Ⅰ型主动脉夹层中的近、远期疗效。
结果整体复合不良结局事件发生率20.6%,浅低温组和中低温组组术后复合不良结局分别为13.6%和22.7%( P=0.535),卒中发生率分别为4.6%和6.7%( P=1.000),浅低温技术组体外循环和主动脉阻断均显著缩短(147.5 min对163.0 min, P=0.032;89 min对99 min, P=0.042)。两组患者远期生存率及再干预率差异无统计学意义(91.9%对89.3%, P=0.87;9.1%对5.3%, P=0.13)。
结论浅低温弓部阻断技术取得了满意的近、远期疗效,相较于中低温技术简化了手术流程,可以作为一种安全、有效的DeBakey Ⅰ型主动脉夹层弓部处理方法。
ObjectiveTo evaluate the safety and efficacy of mild hypothermia arch-clamping technique in the surgical treatment of DeBakey Type Ⅰ aortic dissection.
MethodsFrom December 2019 to November 2023, a total of 97 patients with DeBakey type Ⅰ aortic dissection who underwent arch-clamping technique in Beijing Anzhen Hospital were prospectively enrolled. The patients were divided into mild hypothermia group and moderate hypothermia group according to the lowest rectal temperature during the circulatory arrest period. The perioperative data of the two groups were compared, and complex adverse outcomes consisting of 30-day death, stroke, paraplegia and CRRT were used as the primary endpoint. Multivariate logistic regression was used to determine the predictors of clinical adverse outcomes. Survival analysis was evaluated by the Kaplan- Meier method.
ResultsThe overall incidence of complex adverse outcomes was 20.6%, 13.6% in the mild hypothermia group and 22.7% in the moderate hypothermia group( P=0.535), and the incidence of stroke was 4.6% and 6.7%( P=1.000), respectively. The cardiopulmonary bypass time and aortic-clamping time in the mild hypothermia group were significantly shortened (147.5 min vs. 163.0 min, P=0.032; 89 min vs. 99 min, P=0.042). There was no significant difference in long-term survival and reintervention between the two groups(91.9% vs. 89.3%, P=0.87; 9.1% vs. 5.3%, P=0.13).
ConclusionMild hypothermia arch-clamping technique is a safe and effective method for the treatment of DeBakey type Ⅰ aortic dissection, with satisfactory short-term and long-term efficacy.
