3.2 Effects of antithrombotic use on complications after ST
The background of patients according to their CAT status is summarized in Table 2. Patients undergoing CAT had significantly higher values of APTT (p = 0.002) and PT-INR (p = 0.006) than those of antithrombotic naïve patients.
No statistically significant difference was observed in the number of patients with any complications between patients undergoing CAT (63%) and antithrombotic naïve patients (73%). Comparisons of each postoperative complication (bleeding, infection, and subcutaneous emphysema) also revealed no significant differences between the two groups (Table 3).
