IMPROVEMENT OF THE RHEOLOGICAL PROPERTIES OF BLOOD AS A RESULT OF DIAGNOSTIC APPLICATION OF ULTRAVIST IN THE CASE OF ENDOVASCULAR INTERVENTION IN A PATIENT WITH CHRONIC RENAL INSUFFICIENCYL. N. Gotman and L. I. Ershova UDC 616.155.194:6220.127.116.11:616.13/14073.755.4 It has been shown that the action of a nonionic radiopaque preparation - ultravist (the total dose of iodine is 112 g) - on a patient with chronic renal insufficiency complicated by relapsing massive gastrointestinal hemorrhage, who was subjected to angiographic investigations and radiological occlusion of the bleeding artery, improved the rheological properties of his blood (viscosity of plasma and the aggregation and rigidity of erythrocytes) and did not cause an overall toxic effect.
