End-diastolic velocity (EDV) in vascular ultrasound refers to the speed of blood flow measured at the end of the heart’s relaxation phase (diastole). This crucial parameter helps assess peripheral artery disease, venous insufficiency, and other vascular conditions. Lower EDV can indicate distal arterial occlusion or high resistance, while higher EDV may suggest compensatory flow.
Accurate EDV measurement is vital for diagnostic accuracy in vascular imaging. Sonographers utilize pulsed-wave Doppler to obtain these readings, contributing to comprehensive evaluations of arterial and venous health. Understanding EDV is essential for clinicians to interpret vascular ultrasound studies effectively, guiding treatment decisions for optimal patient outcomes.
