[Angiography of pulmonary hypertension].
In the present report, we reviewed articles on pulmonary angiography for patients with pulmonary hypertension. The use of a non-ionic, low-osmolarity agent and improvements in catheters reduced periprocedual complications, but attention should be paid to the pre-existing poorer physical state. Digital pulmonary angiography has similar diagnostic power to conventional angiography. Wedged pulmonary angiography could demonstrate distal lesions of the pulmonary artery which couldn't be detected by conventional pulmonary angiography. Typical pulmonary angiograms from pulmonary hypertension due to pulmonary embolism, primary pulmonary hypertension, collagen diseases, Takayasu's arteritis and porto-pulmonary hypertension were shown. Pulmonary angiography is relatively less valuable than before because of advances in other diagnostic imaging tools, but still remains the gold standard.
