Complex Decongestive Physiotherapy

Physiology and Pathophysiology of the lymph vessel


system
Lymphology

• Sufficiency, insufficiency of the lymph vessel


system
• Protein-rich (high protein) edema
• Clinical stages / complications of lymph edema
Terms

• Ultra filtrate
small-molecular solution
• Gross filtrate
total fluid filtered (ultrafiltered) by blood capillaries
• Net filtrate / lymphatic load of water
the remaining fraction of approx. 10 to 20 % of fluid
filtered by (nonrenal) blood capillaries into interstitial
space that is not reabsorbed by venous system, but is
returned to blood circulation by lymphatic system
• Lymphatic loads
protein, cells and particles, water, fatty acids
Starling‘s equilibrium

BCPart/ven:
Blood Capillary Pressure

COPPL:
Colloid Osmotic Pressure

(Zutter, 2005)
Starling‘s equilibrium

ID = Interstitial Fluid Pressure

BKD = Blood Capillary Pressure

KODI = Colloid Osmotic


Pressure (Interstitial tissue)

KODP = Colloid Osmotic


Pressure (Plasma)

Sufficieny of lymph vessel system:
At rest

(Földi & Kubik, 2002)

TK: Transportkapazität = Transport Capacity


LZV: Lymphzeitvolumen = Lymph Time Volume
LL: Lymphatic Load FR: Functional Reserve
Sufficieny of lymph vessel system:
Safety Factor

(Földi & Kubik, 2002)


Insufficiency of lymph vessel system
Dynamic insufficiency (high-volume insufficiency)

(Földi & Kubik, 2002)


Insufficiency of lymph vessel system
Mechanical insufficiency (low-volume insufficiency)

(Földi & Kubik, 2002)


Insufficiency of lymph vessel system
Combined insufficiency / „safety valve insufficieny“

(Földi & Kubik, 2002)


The Edema

• Edema (= symptom):
Swelling produced by increase of fluid in
intercellular tissue space.
Visible and palpable, that is clinically apparent
• Lymphedema (high protein edema):
In mechanical insufficiency proteins leave
blood capillary vessels normally, but are not
sufficiently reabsorbed by lymph vessels
(= diagnosis)
Lymphostasis

Stoppage of the flow of lymph fluid:


 Proteins remain in interstitial space
 Proteins are ingested by macrophages
 Macrophages release cytocines (interleukin 1)
 Cytocines activate fibroblasts
 Tissue proliferation
 Lymphostatic fibrosis
