Resection of aneurysm of the aortic arch without cardiopulmonary bypass.

Four cases of aneurysm of the aortic arch were encountered within 1 year at the National Taiwan University Hospital, Taipei, Taiwan, Republic of China. All four patients underwent resection of the aneurysm and graft replacement of the aortic arch without cardiopulmonary bypass or hypothermia. Temporary external shunting with Tygon tube from the ascending aorta to the femoral artery, with and without permanent bypass grafts from the ascending aorta to the carotid arteries, was used in three patients. Permanent bypass grafts with multiple anastomoses was used in one patient. The over-all operative mortality rate was 25 percent. Some adjuncts are made to perfect the safe and simple technique of temporary external shunting, which has been reported previously from the same institution.

Allogeneic cortical strut for benign lesions of the humerus in adolescents.

Allogeneic cortical strut associated with or without cancellous bone grafting for benign adolescent humeral shaft lesions is an alternative management option offering a good chance of stabilization and healing. This study monitored 16 patients who had been treated with this surgical method from 1988 to 1993. There were nine boys and seven girls between the ages of 11 and 16 years (average, 14). Eleven patients had unicameral bone cysts; two had aneurysmal bone cysts; and three had fibrous dysplasia. All 16 patients received fresh-frozen (-70 degrees C) cortical strut inlay grafts in the humeral shaft defect after subtotal excision of the large lesions. No intramedullary rod or plate was used. The follow-up period ranged from 26 to 58 months (average, 41). There were no local recurrences or fractures of the shaft or allograft implants. The radiographs of all humeri revealed the cortical grafts to be well incorporated with new bone formation in the cavity. The overall functional results were good and excellent. This reconstruction with biologically safe and active material provided increased strength and prevented refracture.
