Venous obstruction refers to a blockage in a vein, impeding normal blood flow back to the heart. This condition can be caused by blood clots (thrombosis), external compression from tumors or masses, or structural abnormalities, leading to symptoms like swelling, pain, and skin discoloration. In vascular medicine, timely diagnosis is crucial to prevent complications such as deep vein thrombosis (DVT) and pulmonary embolism (PE).
Ultrasound is a primary diagnostic tool for venous obstruction, allowing real-time visualization of blood vessels. Doppler ultrasound helps assess blood flow patterns and identify occlusions, while B-mode imaging reveals thrombus presence or extrinsic compression. Accurate ultrasound assessment aids in guiding treatment, including anticoagulant therapy or interventional procedures, ensuring optimal patient outcomes in vascular health.
