Abstract：Objective To compare the occurrence of recurrent laryngeal nerve injury after different types of aortic hybrid surgery.Methods A total of 175 patients who underwent aortic hybrid surgery(aortic branch artificial vascular bypass surgery+thoracic aortic endovascular repair)in Beijing Anzhen Hospital,Capital Medical University from December 2019 to December 2021 were selected to analyze the causes of recurrent laryngeal nerve injury after aortic hybrid surgery.The occurrence of postoperative recurrent laryngeal nerve injury and other postop-erative complications in different surgical types were compared and analyzed.Results According to the type of surgery,the 175 patients were divided into the left common carotid artery-left subclavian artery bypass group(77 cases),the left axillary artery-right axillary artery-right carotid artery bypass group(35 cases),the left axillary artery-right axillary artery- left common carotid artery bypass group(20 cases),and the ascending aorta-brachioce-phalic artery bypass group(43 cases).The incidence of postoperative recurrent laryngeal nerve injury in the four groups was 16.9％(13/77),0(0/35),10.0％(2/20)and 18.6％(8/43),respectively,and the difference between the groups was statistically significant(P=0.023).Another 175 patients had cerebral infarction in 6 cases(3.4％),paraplegia in 5 cases(2.9％),acute kidney injury in 3 cases(1.7％),arrhythmia in 3 cases(1.7％),and pulmonary infection in 5 cases(2.9％).Conclusion Recurrent laryngeal nerve injury is one of the postoperative complications of aortic hybrid surgery.There are significant differences in the incidence of recurrent laryngeal nerve injury among different types of hybrid surgery.
