Abstract
James /. Farm and R. Scott Mitchell Acute aortic dissection is an entity not uncommonly encountered by the cardio vascular surgeon.1-3 As the dissection propagates along the aorta, flow to branch arteries may be compromised as a result of a dissection flap or compression by the false lumen at their origins or somewhere along their course leading to ischemia or necrosis of end organs or tissues (Fig. 28.1). The other possibility is that these arter ies may be sheared off resulting in unimpeded or only partially compromised distal flow from the false lumen. Because of the dynamic and unpredictable nature of acute aortic dissection, it is not surprising that approximately 30-50% of affected patients sustain one or more peripheral vascular complications.4-6 Major reported vascular complications of aortic dissection include stroke, paraplegia, peripheral pulse loss and impaired renal or visceral perfusion. From the diagnostic standpoint, abrupt peripheral arterial occlusion in conjunction with an acute generalized illness involv ing unrelated organ systems should prompt strong suspicion of acute aortic dissection.Keywords
