Protein Losing Enteropathy

proteins into the

PLE Pathophysiology Concept
Physiology :
• Liver generates albumin and delivers it into the blood stream
through lymphatic system
• Liver lymph has a high concentration of proteins
• The lymphatic flow in the liver increases significantly in patients
with CHF
Hypothesis:
• The loss of the proteins in PLE happens from the liver lymph
leaking into the intestine
![Page 43: Interventional Management of Lymphatic Morbidity in ......PB Lymphatic Embolization-Outcome • 18 Patients with “cardiac” PB • 16 demonstrated pulmonary lymphatic perfusion](https://reader033.fdocuments.us/reader033/viewer/2022053011/5f0ee5c57e708231d4417a05/html5/thumbnails/43.jpg)
