Shock and the small Aorta
|This patient presents with cardiogenic shock In image a, the right ventricle and right atrium are enlarged and thereare bilateral pleura; effusions. Image b shows stasis of contrast into the IVC and the column is relatively stattic due to peripheral constriction and slow return. There is reflux into the hepatic veins due to tricuspid regurgitation and the reflux extnds all the way to the periphery indicating poor forward flow in the hepatic circulaltion again due to operipheral constriction. Note how small the aorta due to contraction of the muscular media in this life threatening situation.. In image c the celiac axis with branches hepatic artery and splenic artery show severe vasoconstriction. In d the reflux of contrast from tricuspid regurgitaion (TR)extends deep into the renal parenchyma for the reasons outlined above. The patient subsequently developed shocked liver.
