Study Notes
Non-Invasive Procedures
-
Treadmill Test
- Assesses blood flow in extremities post-exercise.
- Identifies exercise-related pain, such as claudication.
-
Plethysmography
- Measures changes in blood volume in calf veins or other extremities using a plethysmograph.
-
Doppler Ultrasound
- Utilizes a Doppler ultrasound flowmeter for measuring blood flow in arteries or veins.
- Useful for diagnosing intermittent claudication, deep vein obstructions, and peripheral vascular disease (PVD).
- May require a Doppler device to assess pulses in cases of PVD, low blood pressure, edema, or significant subcutaneous tissue.
- Record pulse findings as present or absent, avoiding numeric scaling.
- Nurses often mark skin areas with a pulse detected for accuracy in follow-up assessments.
-
Phlebography / Venography
- Considered the gold standard for evaluating deep leg veins and diagnosing deep vein thrombosis (DVT).
- Involves administering a contrast medium via a catheter in a foot vein followed by radiographic imaging to identify filling defects.
-
Fibrinogen Uptake Test
- Accurate method for detecting acute calf vein thrombosis.
- Measures fibrinogen levels at clot sites; fibrinogen tagged with iodine 125 and administered intravenously is detected by a gamma ray detector.
-
Angiography
- Involves intravenous injection of a contrast medium to visualize arteries through radiography.
-
D-Dimer Test
- Measures D-dimer, a fibrin degradation product, in serum to indicate thrombus presence.
- Elevated D-dimer levels are typically associated with thrombus formation.
-
Digital Subtraction Angiography (DSA)
- Involves administering an intravenous contrast solution that enables visualization of blood vessels in extremities through radiographic techniques using an image intensifier and monitor.

Digital Subtraction Angiography (DSA)
- Involves administration of intravenous (IV) contrast solution to enhance visualization of blood vessels.
- Primarily used to visualize blood vessels in extremities for diagnostic imaging.
- Employs radiographic techniques alongside an image intensifier video system for improved image clarity.
- Outputs are displayed on a television monitor, facilitating real-time monitoring of blood vessels.
- Essential for identifying blockages, malformations, or other vascular conditions.
