29. Surgical Considerations in Occlusive Disease of the Great Vessels Arising from the Aortic Arch

E. Stanley Crawford, Michael E. DeBakey, Denton A. Cooley,

and George C. Morris, Jr. (by invitation), Houston, Tex.

Thrombo-obliterative disease of the great vessels arising from the aortic arch is a clinical entity to which various and confusing names have been applied. This has resulted in much confusion as to the nature of the disease process, particularly since some of the proposed concepts of pathogenesis would preclude effective surgical treatment. Our analysis of 40 surgically treated cases supports the concept of the segmental nature of the process. The occlusive process may be extensive and the vessels may be involved in an inflammatory process probably incited by superimposed thrombosis, but the underlying etiologic factor in the majority of cases appears to be atherosclerosis. Some cases had associated segmental occlusive disease in other parts of the major arterial tree emphasizing the clinical patterns of multiple segmental occlusive disease of atherosclerotic origin. Surgical treatment in various modalities restored normal circulation in the distal arterial bed in all cases, including those associated with other occlusive lesions.

30. Coarctation of the Aorta: A Review of 500 Cases

Samuel R. Schuster (by invitation), and Robert E. Gross,

Boston, Mass.

A summary of the preoperative evaluation and operative treatment of 500 cases of coarctation of the aorta will be presented. The follow-up will emphasize the degree of long-term effectiveness of surgical excision of the coarctation. Homograft replacement as utilized in many of these cases over the past twelve years will be evaluated. In addition, the differentiating diagnostic features and operative correction of coarctation of the abdominal aorta will be presented.
