The causes of unilateral edema of the lower extremities is Venous stasis and obstruction

What is meant by peripheral vascular system ?

The peripheral vascular system is made up of peripheral arteries, which are in charge of supplying all body parts with oxygenated blood from the heart, and peripheral veins, which transport deoxygenated blood from the extremities back to the heart.

The peripheral circulation is responsible for the movement of blood, distribution of blood flow, communication between blood and tissue, and blood storage (venous system).

Any tool that enters data and commands into a computer for storage or processing, including sensors and to provide the processed data to a human operator is referred to as a peripheral device. This term is also used to refer to computers.

Venous stasis and obstruction are the causes of unilateral edema of the lower extremities.

What is unilateral edema?

  • Unilateral edema is the presence of excess fluid in the lower extremity, resulting in swelling of the feet and extending upward.
  • Deep venous thrombosis, venous insufficiency, or lymphedema are the most common causes of unilateral lower extremity edema below the knee. The underlying etiology, which is frequently of vascular origin, is frequently revealed by the patient history, physical examination, and lower extremity venous duplex ultrasound.
  • DVT or trauma are the most common causes of acute unilateral lower extremity edema. Chronic unilateral lower extremity edema is most commonly caused by venous insufficiency and, less frequently, by primary or secondary lymphoedema.
  • Bilateral swelling is typically caused by systemic conditions (e.g., cardiac failure), whereas unilateral swelling is frequently caused by local trauma, venous disease, or lymphatic disease.
