“…After Institutional Review Board approval, Current Procedural Terminology code query of Current Procedural Terminology codes 37184-37188 and 37211-37214 revealed 227 patients undergoing CDT or PMT during the specified time frame. Eightytwo were excluded due to existence of preoperative AKI (9), history of end-stage renal disease (ESRD) (14), or lack of perioperative creatinine and glomerular filtration rate (GFR) values (59). The remaining 145 patients were grouped into one of the four following procedural categories: PMT only (n ¼ 15), PMT with tissue plasminogen activator (tPA) pulse-spray (n ¼ 42), PMT with CDT (n ¼ 70), and CDT only (n ¼ 18).…”
