Drainage Flashcards
Inguinal lymph nodes drain?….
- skin of external genitalia
- skin of buttocks and abdomen
- skin and deeper tissues of the dorsum of foot snd the leg
Popliteal lymph nodes drain….
- plantar surface of the foot
- posterior calf
Pelvic and sacroiliac lymph nodes drain…
Sacroiliac
- sciatic pathway
- anus and rectum
Pelvic (iliac)
- urogenital organs
- uterus
- vagina
- urethra
- ureters
- bladder
- lower colon
Alternate pathway of pelvic and sciatic nodes
Sciatic pathway. Not everyone has in bypass inguinal nodes
Abdominal nodes drain…
- stomach
- duodenum
- pancreas
- spleen
- liver - concave surface
- gall bladder
Lumbar nodes and trucks drain…
- ovaries
- testes
- kidneys and adrenals
- lymph from abdominal nodes
Cysterna chyli collects lymph from…
Right and left lumbar trunks and intestinal truck and legs
Thoracic organs are drained by…
Heart - via mediastinal nodes and right bronco-mediastinal trunk
Lung - vessels from lower left lobe follow left bronchus, via hilar lymph nodes crossing at the carina and joining right broncho- mediastinal trunk
Axillary nodes drain…
- arm
- mammary gland
- skin of thorax
Drainage of the breast…
- supraclavicular
- internal mammary nodes
Sentinel node biopsy
Most drainage is to the axilla
- central breast - 100%
- lateral quadrants - 95%
- medial quadrants - 88%
- some retrosternal drainage - 10-50%
Parasternal nodes drain…
- mammary gland medial aspect
- intercostal spaces - ribs 1-9 anterior (attached to sternum)
Paraspinal nodes drain….
- posterior intercostal pathways - ribs 1-13
Lateral to medial to spine
Not skin drainage b/w ribs
Thoracic duct drains…
- left lung
- left cervical nodes
- lungs - upper left
- left parasternal nodes
- para spinal nodes - posterior intercostals
- abdominal and pelvic nodes - inguinal and popliteal nodes
Right lymphatic duct drains…
- right axillary nodes
- right cervical nodes
- heart
- lungs - all right lobes and lower left
- liver - convex surface
- right parasternal nodes
