Lymphatic System Flashcards
Components of Lymphatic System
Lymphatic Vessels > Lymphatic Collectors > Lymphatic trunks
How many main lymphatic trunks are there?
2 main lymphatic trunks.
What is the function of the Right lymphatic trunk?
Right lymphatic trunk is responsible for draining lump from R arm and R side of head
What is the function of the thoracic trunk?
responsible for draining lymph from the remainder of the body
Where do they lymphatic trunks empty?
Empty lymph directly into the venous system via the subclavian veins
Describe Primary lymphedema?
Congenital—abnormal development of lymphatic system
Describe Secondary lymphedema.
Occurs as a result of disease or injury to the system.
May included trauma, surgery, radiation, tumor growth, multiparity, chronic venous insufficiency or infection
List the three types of insufficienceis in the lymphatic system that may lead to lymphedema
- Dynamic insufficiency
- Mechanical insufficiency
- Combined insufficiency
Which insufficiency is the most common?
Dynamic insufficiency
Explain dynamic insufficiency
Excessive lymph circulating in the system which exceeds transport capacity of lymph system
What does dynamic insufficiency result in?
pitting edema
List some examples of dynamic insufficency
- CHF
- Pregnancy
- Chronic venous insufficiency
Explain mechanical insufficency
Transport capacity of the system is decreased d/t damage to the lymph system
Will mechanical insufficiency also result in pitting edema?
No. Mechanical insufficiency results in increased protein-rich lymphedema which is NON-PITTING
Describe combined insufficiency.
There is both an increase in lymph fluid + decrease in transport capacity
What is the primary sign of lymphedema?
Swelling in the extremities.
True or false: A therapist should take blood pressure on a limb with lymphedema
False
When performing circumference measurements, how may circumference points should be taken on the limb?
At least seven circumferences
How would a therapist differentiate lymphedema from lipedema?
Lipedema: Normal Lymphatic function + Symmetrical Swelling of extremities + (-) Stemmer’s sign
Mostly seen in women
When comparing extremities while measuring the circumference of affected extremity, what would classify the affected extremity as having lymphedema?
2-3 cm difference b/t four comparative circumferences on bilateral UE
What is a tell-tale sign of lymphangitis?
Red Stripes proximal to the infection site (typically caused by streptococcus)
What are preventative measures for ppl who are at risk for lymphedema?
- Meticulous skin care/nail care—moisturizer important
- Loose fitting clothing/jewelry
- Extreme temperatures—no hot tub/saunas above 102 degrees
- Lifestyle management—exercise, no heavy lifting
What is Complete Decongestive Therapy for lymphedema?
Treatment model that consists of :
- Phase I: Intensive acute treatment phase (4-6wks)
- Phase II: self-management phase (long-term management)
True or False: patients may need to return to phase I whenever new symptoms appear?
True
What are 4 things that CDT consists of?
- Manual Lymphatic drainage (MLD)
- Compression therapy
- Exercise
- Skin care
The purpose of MLD is?
To move lymph around blockages
