Spontaneous flow in vascular ultrasound refers to blood movement detected without external provocation, critical for assessing vessel patency and identifying abnormalities. This intrinsic flow helps diagnose conditions like deep vein thrombosis or arterial occlusion by confirming blood presence and direction, even in the absence of induced maneuvers.
Understanding spontaneous flow is vital for accurate vascular imaging and diagnostic sonography. Its presence or absence provides immediate insights into vascular health, guiding further investigation and treatment plans for various circulatory disorders.
