A CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries. Its main use is to diagnose pulmonary embolism (PE). [ 1 ]
Selective pulmonary angiogram revealing significant thrombus (labelled A) causing a central obstruction in the left main pulmonary artery. Pulmonary angiography (or pulmonary arteriography,conventional pulmonary angiography, selective pulmonary angiography) is a medical fluoroscopic procedure used to visualize the pulmonary arteries and much less frequently, the pulmonary veins.
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
A thinner microcatheter (about 0.8 mm) is passed through the catheter into the blood vessel, and then, embolic material is injected into the appropriate site. Thus, hemostasis is performed by ceasing or reducing the pressure applied to a bronchial (or non-bronchial)-pulmonary shunt (abnormal anastomosis).
Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...
A defect in the perfusion images requires a mismatched ventilation defect to indicate pulmonary embolism. [8] In the ventilation phase of the test, a gaseous radionuclides such as xenon-133, krypton-81m, or technetium-99m DTPA in an aerosol form is inhaled by the patient through a mouthpiece or mask that covers the nose and mouth.

Intravascular pressure measurement of peripheral arteries ( 00.7 ) Other hip procedures ( 00.70 ) Revision of hip replacement , both acetabular and femoral components
Typical specimen harvested during the surgical procedure of pulmonary endarterectomy in a patient with chronic thromboembolic pulmonary hypertension. Pulmonary endarterectomy (PEA) is the gold standard treatment for suitable CTEPH patients. Operability of patients with CTEPH is determined by multiple factors among which surgical accessibility ...
