What is the differential diagnosis for the patients presenting with unilateral oedema v/s bilateral oedema of the legs?

In CVD, the valves in the veins that help to keep blood flowing upward toward the heart become weakened or damaged, allowing blood to flow back down and pool in the legs, which can cause edema. Edema in CVD usually affects the lower legs and ankles and can vary in severity depending on the stage of the disease. Edema in CVD can cause discomfort and limit mobility, but it can also lead to complications such as skin changes, ulceration, and infection.

Unilateral edema (swelling in one leg) and bilateral edema (swelling in both legs) can have different causes. Unilateral swelling frequently occurs due to local trauma, venous disease, or lymphatic disease, while bilateral edoema typically occurs due to systemic disorders (such as cardiac failure). Edema in CVD can cause discomfort and limit mobility, but it can also lead to complications such as skin changes and ulceration.

In this video, Dr. Kapil, Vascular Surgeon from Madras Medical College, Chennai, will explain the differential diagnosis for the patients presenting with unilateral oedema v/s bilateral oedema of the legs.
