| Objective Retrospectively analyze the data of 32 patients who underwent aorta to ilio-femoral artery bypass because of aortic dissection (AD), aiming to deepen the understanding of this kind of disease.Methods From October 2008 to December 2013, about 32 patients who had AD and received aorta to ilio-femoral artery bypass.28 male patients (87.5%) and 4 female patients (12.5%), with mean age of (42+9) years. Of this 32 patients, there were 28 cases of Standford A aortic dissection (12 cases of acute AD and 16 cases of chronic AD) and 4 cases of Standford B aortic dissection all of whom were chronic AD. All the discharged patients were followed by telephone and computed tomography (CT).Results In regard to the surgery of ascending aorta and arch of aorta, there about 25 patients underwent ascending and total aortic arch replacement with stented elephant trunk implantation, about 5 patients underwent Bentall’s and total aortic arch replacement with stented elephant trunk implantation,2 patients underwent Wheat’s and total aortic arch replacement with stented elephant trunk implantation. All the 32 patients underwent aorta to right iliac or to right femoral artery bypass, cardiopulmonary bypass time of (206±66)min, circulatory arrest time of (26±10)min, and hospital stay time of (20±11) days. 2 patients died after surgery, because of severe complex complications. About 24 discharged patients returned and received CT and follow-up rate was 80%. Time of follow-up by CT was (9±7) months.2 discharged patients were lost in the follow-up by telephone and follow-up rate was 93%. No discharged patient died during the follow-up time.Conclusion For those extended AD patients, following the surgery of ascending aorta and aortic arch, aorta to ilio-femoral artery bypass can relieve the development of the residual AD in early period of post-operation and simplify the second stage operation which can be underwent in normothemia condition. |
