Effect of iohexol on pulmonary arterial pressure at pulmonary angiography in patients with pulmonary hypertension.
The effects of 300 mgI/ml of iohexol on pulmonary arterial pressure at selective pulmonary angiography were evaluated in seven patients with pulmonary hypertension due to pulmonary thromboembolism. The total number of contrast injections was 26. Pulmonary arterial pressure was recorded before and after each injection. The effect of iohexol on pulmonary arterial pressure in the pulmonary hypertensive circulation was slight. The results suggest that iohexol at 300 mgI/ml may be safe as a contrast medium for selective pulmonary angiography in patients with pulmonary hypertension.
