Changes in the patient’s serum hemoglobin (HGB) and hematocrit (HCT) levels before and after surgery. The patient’s HGB and HCT remained at high levels before the surgery, and he was treated with intermittent bloodletting therapies at the local hospital for 9 years. One of the bloodletting therapies was taken on March 14, 2011, and his HGB and HCT declined after the bloodletting therapy. During the time of the two breaks on the horizontal axis, the bloodletting therapy and blood examination was continued, however it was not recorded. His HGB and HCT were controlled within normal levels with bloodletting therapy before surgery at QiLu Hospital. After being discharged from QiLu hospital, the patient’s HGB and HCT levels remained normal without any adjuvant therapy during the 18 months of follow-up.
