Day Three - Lymphedema Classification Flashcards
Lymphedema is caused by a _________ insufficiency of the lymphatic system.
mechanical
Define primary lymphedema.
malformation or dysplasia of the lymphatic system
Name the possible malformations of the lymphatic system, in primary lymphedema.
- hypoplasia
- hyperplasia
- aplasia
- inguinal lymph node fibrosis
What is the most common type of dysplasia in primary lymphedema?
hypoplasia (~ 85% of primary lymphedema cases)
Define hypoplasia.
a form of dysplasia where there are fewer collectors than normal, and the collectors are smaller in diameter
Lymphedema as a complication of hypoplasia more commonly presents in the UE or LE?
can present in both, but more common in LEs, due to gravity
If a patient with a malformation of the lymphatic system develops lymphedema, it is categorized as ________ lymphedema.
primary
True or False. Individuals with primary lymphedema will always show symptoms of lymphedema.
False. Some may never show symptoms, but still have lymphangiopathy.
Define secondary lymphedema.
Lymphedema caused by an insult to the lymphatic system, such as surgery, radiation, infection, trauma, cancer, or self-induced.
True or false. A patient with secondary lymphedema will immediately, and always show symptoms of lymphedema.
False. Lymphedema may present following a latency phase, and may return to latency following CDT.
Inflammation of the lymph nodes is called…
lymphadenitis
Inflammation of the lymph collectors is called…
lymphangitis
What is the most common cause of inflammation of the LS, worldwide?
lymphatic filariasis from mosquito bite transmitted wuchereria bancrofti larvae
How does lymphangiopathy (congenital malformation or dysplasia of the LS) impact transport capacity and functional reserve?
reduces it - results in “subnormal” TC
NOTE: as long as subnormal TC is able to handle LL, lymphedema does not present
What is the term used for Stage 0 lymphedema in primary lymphedema?
lymphangiopathy
