Pulmonary angiography (or pulmonary arteriography,conventional pulmonary angiography, selective pulmonary angiography) is a medical

interventional cardiologist
to visualise the arteries of the lungs.

Uses

Pulmonary angiography is useful as the confirmation test where the non-invasive imaging such as

arterial blood gas results, and ventilation/perfusion scan.[2] Pulmonary angiography is also used to confirm chronic thromboembolic pulmonary hypertension (CTEPH) and provides a platform for balloon pulmonary angioplasty to treat the disease.[3]

CT pulmonary angiography
has nearly entirely replaced conventional pulmonary angiography in common practice as it is less invasive, faster, safer, and provides most of the same diagnostic information with the added benefit of visualizing the lung tissue as well as other structures. Nevertheless, it is still used in cases where CT angiography is nondiagnostic.

Procedure

Types of catheters that can be used are pigtail catheters and balloon occlusion catheters. Tip of the catheter is advanced through the

right ventricle, right ventricular outflow tract, pulmonary trunk, and the tip is parked in the left pulmonary artery.[4]

History

Conventional pulmonary angiography was first performed in 1931 by Portuguese angiography pioneers

Egas Moniz and colleagues.[5] Robb and Steinberg described pulmonary angiography by infusion of peripheral radiocontrast.[6][7]
