SURGICAL TREATMENT OF FUSIFORM THORACIC AORTIC ANEURYSMS BY EXTERNAL REINFORCEMENT.

Replacement of the aorta with a Dacron prosthesis has been the standard method of treating a patient with an aneurysm of the aorta for many years. Aneurysms of the thoracic aorta frequently occur in elderly patients who are poor surgical risks; and under these circumstances surgical correction is associated with a relatively high incidence of postoperative complications. Recently, a technique of reinforcing thoracic aortic aneurysms has been performed successfully in patients in whom the risk of resection and graft replacement was considered too great.
