Surgical treatment of adult complex aortic coarctation

Objective To investigate the therapeutic methods and clinical effect of adult complex aortic coarctation.Methods The clinical data of 6 patients with adult complex aortic coarctation treated by off-pump descending ascendens aorta-aorta abdominalis bypass surgery between December 2005 and July 2012 were retrospectively analyzed.Results There was no death case during the perioperative period in this study; patients showed a substantial improvement in symptoms after the surgery,blood pressure of the lower limbs were elevated,systolic blood pressure difference between the limbs was ＜ 10 mm Hg(1 mm Hg =0.133 kPa).From 5 to 9 months follow-up visit after the 6 patients left hospital,the blood pressure of them was resumed normal.Their angiography by CT showed that,the blood flow in artificial blood vessel of the patients was unobstructed,there was no aorta restenosis or false aneurysm complication.Conclusions The curative effect of off-pump descending ascendens aorta-aorta abdominalis bypass surgery on adult complex aortic coarctation is significant; also the operation technique is a little complex,but it has a high degree of safety and is suitable for clinical application.
