“…Crawford • 19 and others 41 believe that general heparinization increases bleeding, potentiates postoperative hypotension, increases transfusion, and hemorrhage in the pulmonary parenchyma. On the other hand, Dawes et al 49 has demonstrated a protective effect of heparin on the cord, probably by inhibiting the formation of microemboli.…”

Dissecting aneurysm of the aorta was first described by Morgagni' in 1961. Laennec" in 1819, referred to it as "aneurysme dissequant" or dissecting aneurysm. In spite of early recognition of this condition it was not until the turn of the century that Carrell" demonstrated successful resection of thoracic aorta in animals was possible. He repaired the resulting defects by vessel grafts. It was not until 1935 that the technique of fenestration 1 was tried. In 1948, Paullin and James used cellophane to wrap the aorta in an attempt to strengthen the wall, but the method proved unsuccessful. 5 Gross in 1948, first used aortic homografts clinically for replacement of defects in the thoracic aorta."Thoracic fenestration was first described by DeBakey and associates in 1955. 7 Fenestration consists of creating a distal aortic re-entry so as to decompress the dissected aorta. There is reason to suspect that nonsurgical treatment may be more effective than fenestration in the treatment of aortic dissection. Juan, Beckwith, and Muller attempted wrapping the aneurysm with Orion unsuccessfully." In 1957, Cooley, et al. 9 and Gerbode and his associates utilized left atrial to femoral artery bypass during the excision of aneurysms of the descending aorta. Crawford"" reports excellent results utilizing no shunts or partial bypass during resection and graft replacement (Figures 1 & 2). Other authors"" advocate meticulous identification of the origin of the dissection and limiting graft replacement only to this area (Figure 3).
