Abstract

Wedge pulmonary angiography was done in 11 patients with acute respiratory failure, to assess the accuracy of pulmonary arterial wedge pressure (WP) as an estimation of left ventricular end-diastolic pressure (LVEDP). The pulmonary artery (PA) catheter tip was placed into a dependent position in the lungs. Although the pulmonary vein was not visualized in 7 of 11 patients, in no case was there a significant difference between WP and LVEDP. When WP is no greater than 15 mm Hg, wedge pulmonary angiography does not reflect the accuracy of WP; however, left ventricular filling pressure can be accurately estimated by WP in most of these patients.

摘要

对11例急性呼吸衰竭患者进行了楔压肺动脉造影，以评估肺动脉楔压（WP）作为左心室舒张末期压力（LVEDP）估计值的准确性。将肺动脉（PA）导管尖端置于肺内的下垂位置。尽管11例患者中有7例未显影肺静脉，但在任何情况下，WP与LVEDP之间均无显著差异。当WP不大于15 mmHg时，楔压肺动脉造影不能反映WP的准确性；然而，在大多数这些患者中，左心室充盈压可通过WP准确估计。
