Effect of self made artificial blood vessel pre-sewed and wrapped the pericardium on the treatment of Stanford type A aortic dissection / 中国医师进修杂志

ABSTRACT

Objective:To explore the efficacy of right atrium drainage method in Stanford A aortic dissection by using self made artificial blood vessel pre-sewed and wrapped the pericardium.Methods:The clinical data of 60 Stanford type A aortic dissection patients undergoing Sun′s surgery in the First Affiliated Hospital of University of Science and Technology of China from December 2016 to October 2019 were retrospectively analyzed. Among them, 26 patients were treated with directly wrapped artificial blood vessels for right atrial drainage (group A), and 34 patients were treated with self made artificial blood vessel pre-sewed and wrapped the pericardium (group B). The intraoperative and postoperative conditions were compared between 2 groups.Results:All operations were completed successfully. The extracorporeal circulation time, intraoperative red blood cell dosage, intraoperative plasma dosage and 24 h postoperative drainage volume in group B were significantly lower than those in group A (174.09 ± 12.11) min vs. (225.23 ± 20.40) min, (5.56 ± 1.16) U vs. (10.50 ± 2.25) U, (650.00 ± 137.62) ml vs. (953.85 ± 221.33) ml and (515.59 ± 89.16) ml vs. (667.88 ± 76.55) ml, and there were statistical differences ( P<0.01); there were no statistical differences in aortic cross-clamping time, deep hypothermic circulatory arrest time, ventilation time, hospital stay, morbidity and mortality between 2 groups ( P>0.05). Conclusions:Self made artificial blood vessel pre-sewed and wrapped the pericardium is used to perform Sun′s operation in Stanford type A aortic dissection patients, which simplifies the operation and further optimizes the internal drainage technology and is beneficial to reduce the intraoperative blood loss and blood consumption and reduce the extracorporeal circulation time, and the effect is accurate.
