Arterial occlusion is the blockage of an artery, severely restricting or stopping blood flow. This critical vascular condition often results from atherosclerosis, where plaque buildup narrows the artery, or from an embolus (traveling clot) or thrombus (stationary clot). Acute occlusions lead to ischemia, potentially causing tissue damage, organ dysfunction, or limb loss if not promptly treated.
Ultrasound plays a crucial role in diagnosing arterial occlusion. Doppler ultrasound can visualize the occluded vessel, assess blood flow, and identify the extent and location of the blockage. This non-invasive imaging technique is essential for rapid diagnosis and guiding interventions, making it a key tool in vascular medicine and emergency care.
