Other related information
The frequency of preoperative APTT prolongation will be examined in cases managed by anesthesiologist who underwent surgery at our hospital from April 2021 to September 2022, excluding ECT cases and those with deficiencies in patient background and laboratory results. We will also divide the APTT prolonged patients into two groups, mild and severe, and determine whether there are significant differences in patient background (age, gender, ASA classification), PT-INR, and intraoperative blood loss. In the severe APTT prolongation group, we will examine the presence or absence of perioperative thrombotic events and factors contributing to APTT prolongation in the severe APTT prolongation group.
