Patient 4: Mrs. O’Leary The following patient have severe edema for different reasons. Your challenge is to explain the cause of the edema. In each case, try to explain the edema in terms of either an increase or a decrease in one of the four pressures that cause bulk flow at capillaries. A picture may be useful. Mrs. O’Leary is recovering in the oncology ward. She was diagnosed with advanced breast cancer that had infiltrated her right breast and axillary lymph nodes. All of her axillary lymph nodes were surgically removed a few days prior to presentation, which severed most of the lymphatic vessels draining her right arm. Mrs. O’Leary’s right arm is very swollen, and she is wearing a compression sleeve to wear on her right arm to help relieve the pitting edema. What is causing her edema? Which pressure is altered by the compression sleeve, and how will this relieve her edema?
