Radiation-Associated DNA Damage in Operators During Endovascular Aortic Repair

Abstract

spinal cord ischemia, respiratory and renal and insufficiency. Secondary end points included blood loss, operative time, ICU stay, the length of hospital stay. Results: Primary endpoints: 30 days mortality rate 24.1% (7.18% standard group, p ¼ 0.001), spinal cord ischemia rate 13.8% (14.1% standard group, p ¼ 0.964), respiratory failure rate 13.8% (4.95% standard group, p ¼ 0.0442) and renal failure rate 27.6% (26.2% standard group, p ¼ 0.869). Secondary endpoints: mean blood loss 7062 mL (5246 mL standard group, p ¼ 0.018), mean operative time 5,39 h (4,79 h standard group, p ¼ 0.021), mean ICU stay 3.4 days (2.7 days standard group, p ¼ 0.068), length of hospital stay 10.7 days (10.4 days standard group, p ¼ 0.852). Conclusion: Previous thoracic endovascular repair is a significant preoperative risk factor for patients requiring subsequent open TAA repair. Not only does it increase the complexity of the repair with longer operative time and blood loss but also there is a worsening in terms of both mortality and respiratory morbidity.
