概括

重新冠状动脉旁路移植 (CABG) 正在增加,患病率较高,但调整后死亡率低于首次CABG. 动脉管道,特别是内部乳腺动脉,可能会改善复制CABG患者的存活率.

科学领域:

心血管外科心血管外科
胸部外科手术胸部外科手术
血管外科血管外科

背景情况:

重新冠状动脉旁路移植 (CABG) 是一种高风险的手术,具有显著的病率.
管道选择对于CABG后的结果至关重要,但重复操作的趋势尚不清楚.
需要具有全国代表性的数据来分析在重复CABG中的管道使用和死亡率.

研究的目的:

检查重复对抗首次CABG的管道选择当代趋势.
为了确定重复绕道术的患者死亡的风险因素.
为了比较重复和首次CABG患者之间的结果.

主要方法:

使用了2016-2021年全国再接收数据库,用于接受隔离CABG的成年患者.
将患者分为两层,分为第一时间和Redo队列.
评估了管道使用的时间趋势 (内部乳腺动脉,放射性动脉,静脉) 和住院死亡率,术后并发症,住院时间,费用和再入院.

主要成果:

在928,925个孤立的CABG病例中,Redo CABG占5.3%.
内部乳腺动脉,辐射动脉和沙静脉的使用量从2016年到2021年在两个队列中都增加了.
重制CABG的并发症较高,住院时间较长 (+6.2天),成本增加 (+11,100美元),但住院死亡率较低 (aOR 0.75).
内部乳腺动脉使用与降低死亡率 (aOR 0.57) 有关.

结论:

Redo CABG正在增加,与更高的发病率和资源使用有关,但调整后死亡率较低.
在重复CABG中调整后的较低死亡率可能源于仔细的患者选择和重症监护.
动脉管道,特别是内部乳腺动脉,在重复CABG中显示出生存益处,并需要进一步调查.
