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)
