Preoperative Approach to Hereditary Angioedema Patients in Two Cases

Our aim is to draw attention to the importance of prophylactic treatment in preoperative, perioperative and postoperative period for hereditary angioedema patients for whom minor or major surgery is planned. Two patients with a diagnosis of hereditary angioedema were treated with 1000 IU C1 esterase inhibitor 1-6 hours before minor surgery. Case 1 did not develop an attack during the procedure and within postoperative one month. In case 2 with incomplete lupus erythematosus, angioedema occurred in the lips one hour after the procedure. One more dose of C1 esterase inhibitor was administered to the patient and angioedema was delayed within half an hour. In this study, it was aimed to emphasize the importance of prophylactic treatment to prevent attack development during the procedure in patients with hereditary angioedema
