[A case of aorto-coronary bypass surgery in a hypophysectomized male patient]

A 53-year-old hypophysectomized male patient who had been on adjuvant therapy with cortizol and thyroxin, underwent aorto-coronary bypass surgery for angina pectoris with 3 vessel obstruction. Following revascularization surgery, he had an uneventful course until 8th post-operative day, when he experienced about of unconsciousness which was relieved by intravenous hydrocortizon supplement. Simultaneously complicated bradycardia and peripheral coldness were considered to be due to lowered serum T3 and T4 values. By the time the thyroid function stabilized, three times as much as preoperative dosage of thyroxin had to be administered for 34 days. The control of the hypothyroidism plays an important role in the postoperative management of the patient with panhypopituitarism after the cardiac surgery.
