Clinical studying of thoracic endovascular aortic repair for treating multiple tears Stanford type B thoracic aortic dissection / 国际外科学杂志

ABSTRACT

Objective This study aims to analysis in the clinical features of Stanford type B thoracic aortic dissection with multiple tears,and to explore the clinical methods of thoracic endovascular aortic repair (TEVAR) treating this disease.Methods From February 2011 to May 2015,the cases that diagnosed with multiple tears (≥ two tears) Stanford type B thoracic aortic dissection and accepted operations with TEVAR at department of Thoracic Cardiovascular Surgery,Wuhan General Hospital of Guangzhou Command,were retrospective analyzed their clinical data.Except the first tear of proximal,cases were named for the treatment group whom used surgical methods treating distal aortic dissection tears.Otherwise,the cases were named non-treatment group.We compared the incidence of chest and back pain,the progress of distal aortic dissection,the changes of false lumen with aortic dissection,and the benefit of distal tears in two groups after 6 months after TEVAR.Results A total of 67 cases were recruited this retrospective study,successful operations with TEVAR were conducted in all patients,and no serious complications occurred postoperatively in all patients.7 cases with treatment group,60 cases with non-treatment group,no deaths within two groups in 6 months after TEVAR.There were no significance statistically in complained of the incidence of chest and back pain,and the rate of progress with distal aortic dissection (P ＞ 0.05).There was statistically significant in the rate of changes with false lumen with aortic dissection false lumen (P ＜ 0.05).Some cases with abdominal visceral artery blood flow from the distal tears of aortic dissection in the non-treatment (n =19).Conclusions TEVAR is an effective method for treating multiple tears Stanford type B thoracic aortic dissection.Distal tears should be individualized treatment according to the characteristics of Stanford type B thoracic aortic dissection or try not to deal with.
