immobility, Alterations in Lymphatic Flow
Lymphedema Lymphatic vessels contain valves similar to those in veins.
Lymphatic Lymphedema is an abnormal buildup of lymphatic fluid in
the dermal and subcutaneous tissues.

overwhelmed Lymphedema may be primary or secondary in etiology.
Primary lymphedema is congenital (people can be born
without some lymph nodes). Secondary lymphedema is
more common caused by trauma, recurrent infections,
obstructive mass, infiltrative processes, and radiation can
cause lymphatic vessel damage. Upper extremity lymphedema may occur after radical or
modified radical mastectomy. Manifestations include regional edema and thickened
