LDL apheresis

LDL apheresis is a medical procedure that removes LDL cholesterol (the "bad" cholesterol) from the blood of patients who have a genetic condition called Familial Hypercholesterolemia (FH) that can't be controlled with diet, exercise or medication. A machine with special filters are used to remove the LDL cholesterol from the patient's blood and then it is returned to them, using needles that are placed in each arm. Sometimes the patient may have a shunt surgically placed in their arm for this treatment. LDL apheresis is a life-long therapy that is required every two weeks, and a typical procedure lasts about two hours.
