Abstract

Cross-clamping of the descending thoracic aorta is followed by dramatic alterations in hemodynamics. The increase of the arterial blood pressure proximal to the occlusion (APprox) may cause cerebral hemorrage, pulmonary edema or cardiac dilation, whereas the marked distal pressure (APdist) decrease leads to impaired organ perfusion which can result in severe ischemic/anoxic organ dysfunction, especially in paraplegia. The reported postoperative incidence in the human ranges up to 24% (Coles et al., 1983).
