Primary v. Secondary Lymphedema Flashcards
primary lymphedema
mechanical insufficiency of the lymphatic system
onset of primary
praecox v. tarda
praecox accounts ofr
83% of al primary cases
before the age of 35
tarda is come common
after the age of 35
primary lymphedema is more common in
females around the age of 17
types of primary
hypoplasia
hyperplasia
aplasia
inguinal node fibrosis
milroys dz or type 1 congenital hereditary lymphedema
meige’s syndrome or type II
hypoplasia
less than normal expected number of lymph node collectors
collectors may be of insufficient caliber to fxn as transport vessels
most common form of primary
hypoplasia
hyperplasia
vessels are excessively dilated
causes them to be less fxnal d/t valvular dysfxn
aplasia
absence of lymph node collectors
absence of lymph node capillaries
makes the collectors less fxnal
what is aplasia most often combined w/
hypoplasia
b/c a complete aplasia would render the tissues non-viable to support life
inguinal node fibrosis is also known as
kinmouth syndrome
fibrosis
fibrosclerosis
fatty degeneration
morphological changes to the iliac and inguinal lymph nodes
milroys dz or type I congenital hereditary lymphedema
affects children at birth or presents shortly after birth
milroys dz or type I congenital hereditary lymphedema is more common in
males
milroys dz or type I congenital hereditary lymphedema usually involves
one LE but can involve both LE
arm
genitals
face
meige’s syndrome or type II
non-congenital hereditary lymphedema
meige’s syndrome or type II is more common in
females
onsets during puberty
meige’s syndrome or type II usually involves
involves the LEs
rarely involves other body parts \
meige’s syndrome or type II can involve
fusion of two or more toes
two rows of eyelashes
near sightedness
yellow nails
vertebral anomalies
Cervero-vascular malformations
senso-neural hearing loss
cleft palate
secondary lymphedema has
multiple causes
multiple causes of secondary
surgery
radiation
trauma
filariasis
cancer
infection
self-induced
chronic venous insufficiency
obesity
radiation –> secondary
fibrosis restricts transport
filariasis –> secondary
mosquito born parasite
most common case world wide
cancer –> secondary
most common cause of lymphedema in the US
senf-induced –> secondary
via prolonged turniquet
obesity –> secondary
pannus restricts inguinal node
sitting/inactivity restricts drainage
types of –> secondary
malignant lymphedema
benign lymphedema
malignant lymphedema
sxs more rapid and proximal
d/t blockage from a tumor or DVT
