Objective:Analysis the protective effect of the partial femoral to femoral cardiopulmonary bypass(CPB) on thoracoabdominal aortic aneurysm repair(TAAAR).Methods:From September 2016 to August 2020, 50 cases of TAAAR under partial CPB were performed at our hospital. Thirty males and 20 females with an average age of(40.5±12.4) years old(ranging 21 to 69 years old) were involved. Partial CPB without selective organ perfusion were applied at the early stage. Since November 2019, the adjunct of perfuse the celiac and superior mesenteric artery with warm blood and irrigate the renal artery with 4℃ HTK solution was used in TAAAR, and 25 patients were operated under this adjunct.Results:The average CPB time was(116.9±35.4) min, the lowest central body temperature during the partial CPB was(34.7±0.7)℃. Total early postoperative mortality was 6%(3/50, 3 deaths in partial CPB alone group). Paraplegia occurred in 4 cases(8%), new happened postoperative hemodialysis was in 6 cases(16%). Among the hemodialysis event, 2 cases(8%, 2/25) were in the group with selective organ perfusion, and 4 cases(16%, 4/25) in the group without using the adjunct.Conclusion:Mild hypothermic partial cardiopulmonary bypass combined with selective organ perfusion have protective effects on spinal cord and abdominal organ in patients underwent TAAAR.

Objective To evaluate the efficacy and safety of preoperative intra-aortic balloon pump(IABP) insertion in acute myocardial infarction(AMI) without cardiogenic shock(CS) patients receiving off-pump coronary artery bypass grafting ( OPCABG).Methods 444 consecutive AMI patients who underwent isolated OPCABG from January 2009 to December 2016 were enrolled.158 patients who underwent preoperative IABP placement(IABP group) and the other of 286 patients who did not have IABP placement(control group).The in-hospital mortality rate, postoperative complications, mechanical ventilation time, ICU stay and hospital length were compared between the two groups.Results The overall mortality was 5.0%.135 pairs of patients were matched.The preoperative IABP insertion showed benefits in postoperative survival rate compared with the control group(0 vs.5.9%, P=0.004).However, patients with preoperative IABP were more likely to prolong duration of mechanical ventilation and ICU stay.The postoperative length of stay in hospital didn't show significant difference between the two groups.Conclusion Survival advantage was observed from preoperative IABP insertion in AMI patients without CS under-going OPCABG.
