Effect of an Iso-Osmolar Contrast Medium on Pulmonary Arterial Pressure at Pulmonary Angiography

Pulmonary arterial pressure at high pulmonary flow.

The relationship between pulmonary arterial pressure and pulmonary blood flow has been studied by a number of investigators in anesthetized animals (1), in man after pneumonectomy or unilateral pulmonary arterial occlusion (2, 3), and in normal man during exercise (4-7). With a few exceptions (1) these studies have agreed that doubling or trebling the pulmonary arterial flow does not produce a ...

Iso-Osmolar versus Low-Osmolar Contrast Media in Reducing Contrast Induced Nephropathy in Patient with Renal Impairment Undergoing Coronary Angiography

THE EFFECTS OF CAPTOPRIL ON PULMONARY AND SYS TEMIC ARTERIAL PRESSURES IN HIGHALTITUDE PULMONARY HYPERTENSION

The purpose of this investigation was to assess the effect of captopril on both systemic (P.a) and pulmonary arterial pressures (PPA) in patients with high-altitude pulmonary hypertension (HAPH). Seventeen patients (mean age 44±6.8 years) with HAPH and mild to moderate systemic arterial hypertension were included in the study. All patients underwent right heart catheterization with measurem...

Assessment of pulmonary arterial enhancement on CT pulmonary angiography using a leg vein for contrast media administration

The purpose of our study was to compare pulmonary artery (PA) enhancement according to venous routes of contrast media (CM) administration in patients who underwent CT pulmonary angiography (CTPA) in the emergency department (ED).This retrospective study reviewed the CTPAs of 24 patients who administered CM via leg veins (group A) and 72 patients via arm veins (group B) with age and gender matc...

Effects of Intra-Arterial and Intravenous Iso-Osmolar Contrast Medium (Iodixanol) on the Risk of Contrast-Induced Acute Kidney Injury: A Meta-Analysis.

BACKGROUND: The iso-osmolar contrast agent iodixanol may be associated with a lower incidence of contrast-induced acute kidney injury (CI-AKI) than low-osmolar contrast media (LOCM), but previous meta-analyses have yielded mixed results. Objectives: To compare the incidence of CI-AKI between iodixanol and LOCM. METHODS: Studies were identified from literature searches to December 2009, clinica...
