(A) Anteroposterior angiogram of the right pulmonary artery shows no abnormality. Kuo WT. Kuo WT. NB: This article is intended to outline some general principles of protocol design. [Medline].  there are no absolute contraindications to catheter pulmonary angiography. Pulmonary artery catheterization: a modified technique. J Vasc Interv Radiol. [Medline]. [Medline]. Materials and methods: A Medline search was constructed to include all English language publications indexed in the Index Medicus from 1990 to 2000, which included the terms CT, PE and pulmonary angiography. A guidewire (arrowhead) was used for navigation. Cardiac Catheterization and Coronary Angiography" in Rosendorf, Essential Cardiology. 2nd Ed. [Medline]. [8, 9, 10, 11, 12] Indications include hemodynamic instability, right heart strain/failure, severe hypoxemia, free-floating right ventricular (RV) thrombus, patent foramen ovale (PFO), and failed systemic thrombolysis. Eur Radiol. Semin Respir Crit Care Med. Arteries are blood vessels that carry blood away from the heart. CT pulmonary angiogram (CTPA) is used to examine the pulmonary arteries in the lungs, most commonly to rule out pulmonary embolism (PE), a serious but treatable condition. J Vasc Interv Radiol. Measuring pressures in the heart and pulmonary arteries may be necessary, especially when evaluating a patient with chronic thromboembolic disease. Step 1: The patient is helped to relax using a sedative. Within the last several years, spiral computed tomography angiography (SCTA) of the pulmonary arteries has emerged as a noninvasive angiographic modality for the evaluation of patients with suspected pulmonary embolism (PE). [9, 11], Numerous articles have described a multitude of techniques for accessing the pulmonary arteries, some using specialized catheters and guidewires. Massive pulmonary embolism: treatment with the hydrolyser thrombectomy catheter. Radiology. Selective left pulmonary angiogram shows abrupt tapering of the segmental pulmonary arteries (arrow) with heterogeneous opacification of the parenchyma. Medscape Education. 33(2):199-204. 2nd ed. Clin Cardiol. Nilsson T, Carlsson A, Mâre K. Pulmonary angiography: a safe procedure with modern contrast media and technique. Pulmonary angiography is considered the gold standard for the diagnosis of PE, although recent evidence does not necessarily always support that. 7 The veins used for catheterization of the pulmonary artery are the femoral, jugular and upper extremity vein. [Medline]. J Vasc Interv Radiol. 14(6):711-27. This shape was designed for access from the right femoral vein and allows for easier maneuvering through the right heart and pulmonary arteries. [Medline]. CT angiography (CTA) is considered the gold standard in diagnosis of PE . (A) Selective right pulmonary arteriogram shows large filling defects in the right upper (short arrow) and right lower (long arrow) lobe pulmonary arteries. [Medline]. Miller DL, Balter S, Cole PE, Lu HT, Schueler BA, Geisinger M. Radiation doses in interventional radiology procedures: the RAD-IR study: part I: overall measures of dose. 2011 Dec. 146(12):1428-32.
