Lymphedema--Jen Flashcards
1
Q
Lymphotomes
A
- anatomical regions that drain to same area
- left/right and upper/lower
2
Q
Lymph flows toward:
A
- nodes from peripheral tissues
- controlled by bicuspid valves of lymphangion
3
Q
lymphangion
A
- segment of lymph vessel that contains a bicuspid valve
- has smooth muscle
- lined with epithelial cells
4
Q
Smooth Mm Contraction of lymphangion
A
- initiatied by pressure increase outside the vessel
- pumps only 3-4 times per min
- need skeletal movement to move fluid
5
Q
lymph vessels empty into:
A
-veins near internal jugular and subclavian veins
6
Q
How many nodes in body
A
-600
- 160: head neck
- 200: digestive system
7
Q
Ducts/Trunks
A
- larger lymph vessels
- lumbar trunk and intestinal trunks flow to cisterna chili then to thoracic duct at venous angle
8
Q
Pressure change by respiration increases____
A
rate of lymph flow into the thoracic duct
9
Q
Function of Lymph System
A
- maintain balance of fluids
- return fluid/substances from interstitium to blood stream
- differentiate between foreign and self cells
10
Q
Lymph Fluid Contains
A
- water
- proteins
- cytokines
- enzymes
- lymphocytes
- macrophages
- –bacteria, fungi, viral, tumor cells
11
Q
Lymphadema
A
- abnormal collection of excessive tissue proteins, edema, chronic inflammation and fibrosis
- lymph load>total capacity
12
Q
complications of lymphadema
A
- recurrent infection (cellulitis etc)
- chylous reflux
- lymphocutaneous fistulae (weeping) pathways from lymph vessel to surface of skin
- lymphangiosarcoma
13
Q
chylous reflux
A
-backflow of intestinal lymph
14
Q
Lymphangiosarcoma
A
-cancer of lymphatic vessels
15
Q
Risk Factors
A
- axillary surgery (any cancer surgery)
- radiation therapy
- mastectomy
- axillary node dissection
- obese
- delayed wound healing
- tumor causing lymphatic obstruction
- scarring ducts from surgery/radiation
- intrapelvic/intra-abdominal tumors
- chronic venous insufficiency
16
Q
Medical Management
A
- no meds, no surgery
- PT
