LYMPH Flashcards
Most Common Causes of LE edema
- chronic venous insufficiency
- CHF
- idiopathic edema
- pulmonary HTN
some causes of LE Edema
- chronic venous insufficiency
- CHF
- idiopathic edema
- pulmonary HTN
medication, renal disease, liver disease, premenstrual edema, pregnabcy/preeclampsia, obesity, lymphedema, beriberi, mat thumer syndrome, lipidema, myxedema, malignancy, high sodium diet, compartment syndrome, baker’s cyst, acute swelling
What causes lymphedema
- Plasma/blood
- Interstitial fluid
- lymphatic fluid
- lymph capillaries
- lymph nodes
- blood stream
what does lymph fluid do?
lymph fluid washes all the cells in the body: clears out waste products, transports foreign cells (bacteria) to lymph nodes, and provides nutrition to interstitial tissues and cels
explain in lay man terms lymphatic system
Body drain system, nodes are plumbers, vessels are pipelines
after filtration: lymph fluid leave the body in urine
lymphedema: occur after a disruption to the lymphatic system cause stagnant lymph fluid in the skin
mechanical insufficiency in lymphedema
mechanical insufficiency: problem with transportation of lymph fluid
lymph fluid has high protein concentration-only lymphatic system can absorb high protein lymph fluid -cannot leave in osmosis
vicious cycle of lymphedema
proteins are hydrophilic sponges, when there is a mechanical insufficiency of the lymphatic system lymph fluid remains in the interstitial (area between cells) proteins stay there 1. more H2O absorbed 2 grow bigger 3. inflammation 4. fibrotic tissue build 5. visible swelling.
Factors: Edema with a lymphatic origin
- lymph node resection (taken out)
- tumor block of lymph vessels (obstructs the vessels)
- severed lymph vessels
- burns (lymph close to skin)
- filariasis
- trauma
right UE lymphedema
axillary lymph nodes resected from right armpit
LE lymphedema
post surgery (TKR, THR, pelvic surgery, irradiation)
Staging Lymphedema
4 stages, incurable at stage 2 (irreversible)
Stage 0: lifetime risk to develop lymphedema
Stage 1: reversible lymphedema
Stage 2: IRREVERSIBLE lymphedema
Stage 3/4: elephantiasis lymphedema
where are lymph nodes most?
head and neck
also in abdomen, popliteal, cubital fossa and anywhere with fatty adipose tissues
where do you want to bring the lymph after a surgery?
to areas of functional lymph nodes
R side compromise: bring it down ipsilateral and across contralateral
Lymphedema Stage 0
at lifetime risk of developing lymphedema but no clinical signs or sx
[had a surgery by the lymph nodes but no lymphedema as of now]
Lymphedema Stage 1
reversible stage of lymphedema
pitting edema occurs
–if tx quickly can bring them to 0 (but will always have at least 0)
