Liu Y, Zhang B, Liang S, et al. - This retrospective review was conducted to determine how body mass index (BMI) can alter surgical results in patients with acute Stanford type A aortic dissection (ATAAD). From a single centre, clinical data of 268 ATAAD patients were obtained. Patients were grouped depending on BMI: normal weight (BMI 18.5 to < 25 kg/m ² , n = 110), overweight (BMI 25 to < 30 kg/m ² , n = 114) and obese (BMI ≥30 kg/m ² , n = 44). Findings revealed that early major adverse outcomes as well as mid-term survival following surgery for ATAAD were not impacted by BMI. In ATAAD cases, satisfactory surgical results can be achieved at all weights.
