Perioperative serum procalcitonin concentrations in patients with acute aortic dissection.
We investigated the perioperative serum procalcitonin (PCT) concentrations in 5 consecutive patients who underwent surgery for acute aortic dissection (2 men, 3 women; mean age 72 +/- 9 years, age range 52-81 years). Surgery used cardiopulmonary bypass with deep hypothermic circulatory arrest. Blood samples were taken prior to surgery, upon arrival in the intensive care unit, and 6, 12, 18, 24, and 48 h after intensive care unit arrival. Prior to surgery, the PCT level was 4.2 +/- 3.4 (range 0.8-8.3) ng/ml. The PCT increase was greatest at 24 h (5.8 +/- 4.5 ng/ml). Preoperatively, the C-reactive protein concentration was 8.0 +/- 8.3 (range 0.9-23.8) mg/dl, and the white blood cell count was 8.5 +/- 3.1 x 10(3). C-reactive protein continued to increase at 48 h, while the white blood cell count peaked at 24 h. In spite of no symptoms of infectious diseases or septicemia, all patients had a significant preoperative PCT elevation. This finding may have something to do with the specific preoperative condition of acute aortic dissection. However, more clinical investigation is needed to clarify the PCT changes during and after surgery for acute aortic dissection.
