Operation Definition
Single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on a fluorescent screen. The image may also be stored by either digital or analog means
Procedure Overview
Fluoroscopy of the upper arteries is a real-time x-ray technique in which contrast dye injected into the bloodstream is tracked continuously on a screen as it travels through the subclavian, axillary, brachial, or other arm arteries. This moving picture, often called an arteriogram, lets a physician see narrowing, blockage, aneurysm, or abnormal connections between vessels as blood actually flows past them, which a single static image cannot show.
It is typically performed when a patient has symptoms suggesting reduced blood flow to the arm, such as pain, coolness, or weak pulses, or to plan and guide a subsequent procedure like angioplasty or stent placement. A catheter is usually threaded through a blood vessel to the area of interest, contrast is injected, and the radiologist watches the images live, sometimes storing them digitally for later review.
Anatomy & Axis Detail
Cervico-Cerebral Arch
The cervico-cerebral arch refers to the aortic arch together with the great vessels and cervical arteries that arise from it and ascend toward the brain, effectively capturing the entire pathway from the heart to the neck vessels in one continuous view. Fluoroscopic imaging of this arch is performed as a comprehensive survey before selective catheterization of individual carotid or vertebral arteries, allowing the angiographer to assess the number, origin, and tortuosity of the great vessels, which varies among patients and affects how subsequent selective studies are approached. This arch-level view is particularly useful in stroke workup and carotid stenting planning, where the configuration of the arch itself, such as a bovine origin or unusually acute branch angles, can materially change catheter selection and procedural risk.
Contrast: Other Contrast
Other Contrast captures imaging studies using a contrast medium that is neither high- nor low-osmolar iodinated agent, such as barium sulfate for gastrointestinal studies or gadolinium-based agents for certain applications outside standard MRI classification within this axis. It is used when the contrast administered does not fit the osmolarity-based iodinated categories, distinguishing it from those specific classes and from studies performed with no contrast.
Coding & Documentation
Documentation must confirm that contrast was injected and that imaging was captured in real time, since this is what distinguishes fluoroscopy from plain radiography of the same vessels. The specific artery or arterial segment imaged drives the body part selection, and the coder should verify whether the study was purely diagnostic or performed as guidance for an interventional procedure, since guidance fluoroscopy for a separate therapeutic intervention is not coded the same way as a standalone diagnostic arteriogram. A frequent error is failing to capture bilateral studies correctly when both upper extremities were imaged in the same session, or coding the catheter insertion site as the imaged body part instead of the artery actually visualized.
Commonly Confused With
This family is closely related to and often confused with CT angiography of the upper arteries, since both use contrast to visualize the same vessels; the distinguishing factor is that fluoroscopy produces a live, continuously viewed image during contrast injection while CT produces a computer-reconstructed set of cross-sectional images from multiple static exposures. It is also distinguished from plain radiography of the same arteries, which involves no contrast tracking and no real-time viewing, and from ultrasonography, which assesses flow using sound waves rather than ionizing radiation and injected dye.
