Mechanism of increased cerebrospinal fluid pressure with thoracic aortic occlusion

Fig. 1 Aortic occlusion resulted in increased CVP, which was augmented by volume loading (*p < 0.05). Journal of Vascular Surgery , DOI: ( / (90)90216-W) Copyright © 1990 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

Fig. 2 The increase in CSFP in response to thoracic aortic occlusion was greatest in volume loaded animals (*p < 0.05).

Fig. 3 With aortic occlusion, the increase in CSFP (ΔP0) was equal to or greater than the increase in CVP (ΔCVP) (*p < 0.05).

Fig. 4 Compliance was not changed by aortic occlusion alone. Volume loading in group II was associated with an increase in compliance (*p < 0.05).

Fig. 5 Starling resistor model applied to spinal cord blood flow (see text). If CSFP exceeds local venous pressure, veins can collapse (arrows) thereby increasing outflow resistance.
