ARRT Vascular-Interventional Radiography case studies
ARRT Vascular-Interventional Radiography · Put your knowledge to work in context.
ARRT certification and registration in Vascular Interventional Radiography (VI) recognizes technologists qualified to perform the role of a Vascular Interventional Radiographer. These technologists assist physicians with minimally invasive, image-guided vascular procedures - including angioplasty, stenting, and thrombolysis - and use sophisticated fluoroscopic equipment to capture images of blood vessels, working in hospitals, clinics, labs, or outpatient centers. The ARRT Vascular-Interventional Radiography case studies are 5 cases and about 2,359 words.
1Post-Thrombolysis Rebleed During Catheter-Directed Therapy
A 58-year-old man is on day 2 of catheter-directed thrombolysis for an extensive left iliofemoral DVT. Current infusion: alteplase 0.5 mg/hr via a multi-sidehole catheter in the common femoral vein.

A 71-year-old woman with CKD stage 4 (eGFR 22 mL/min/1.73 m²) and a non-healing right toe ulcer is scheduled for diagnostic angiography and possible below-knee intervention. She has had prior contrast reactions (hives) and a documented iodinated contrast allergy.

A 64-year-old man is scheduled for a diagnostic lower-extremity angiogram with possible intervention. During pre-procedure assessment you note: he takes metformin, has an eGFR of 38 mL/min/1.73 m², reports a prior 'reaction' to contrast that involved flushing and nausea but no hives or airway symptoms, and has a known abdominal aortic aneurysm.

During a runoff angiogram, the images become progressively degraded: the vessel edges are fuzzy, there is motion-like blur on the distal frames, and the last few acquisitions look washed out with poor contrast. The patient is awake and slightly restless.
