Perioperative variables
Forty-four patients had undergone aortic dissection surgery in our center during the period 2011-2017. Out of these, 11 patients either died on the table or didn’t have post-op CK levels and hence were excluded from the study. Of the remaining 33 patients, 21 patients (63.64%) developed RML based on our diagnostic cut off value of CK (Group RML) and 12 did not (Group non-RML).
Other preoperative and intraoperative factors like critical preoperative states, congestive heart failure, renal artery involvement, cannulation method, type of surgical procedure etc. did not have a significant impact on the incidence of rhabdomyolysis postoperatively (Table 1). Patients who developed rhabdomyolysis had a higher body mass index (BMI) when compared to those who didn’t, but this difference failed to achieve a statistical significance (P-value 0.07). Of note, patient with a delayed presentation for surgery tends to develop RML less frequently than those presenting early (P-value 0.03)
