CLT Lymphedema Pathophysiology & Staging 2

Question 1

Elephantiasis is associated with which stage of lymphedema?

Accepted Answer

Stage III

Answer

ISL Stage III (lymphostatic elephantiasis) features massive limb enlargement with skin changes including papillomas, lobules, and acanthosis.

Question 2

The most common cause of secondary lymphedema worldwide is:

Accepted Answer

Filariasis (parasitic infection)

Answer

Lymphatic filariasis caused by Wuchereria bancrofti is the most common cause of secondary lymphedema globally, though cancer treatment is the leading cause in the US.

Question 3

What is the 'safety valve' of the lymphatic system?

Accepted Answer

The lymphatic system's reserve capacity to handle excess fluid beyond normal load

Answer

The safety valve refers to the lymphatic system's ability to increase flow by 10–20 times above baseline when interstitial fluid accumulates.

Question 4

Dynamic insufficiency of the lymphatic system means:

Accepted Answer

The lymphatic transport capacity is normal but the lymphatic load is too high

Answer

Dynamic insufficiency occurs when normal lymphatic transport capacity cannot keep up with an abnormally high lymphatic load, as in heart failure or severe hypoproteinemia.

Question 5

Mechanical insufficiency of the lymphatic system means:

Accepted Answer

The lymphatic transport capacity is reduced below the normal load level

Answer

Mechanical insufficiency occurs when lymphatic transport capacity is reduced (e.g., by node removal) so it can no longer handle even a normal lymphatic load.
