LDL apheresis
LDL Apheresis
LDL apheresis (pronounced: el-dee-el a-fuh-REE-sis) is a medical procedure used to treat patients with significantly high levels of low-density lipoprotein (LDL), often referred to as "bad cholesterol".
Etymology
The term "apheresis" is derived from the Greek word aphairesis, meaning "to take away". LDL stands for Low-Density Lipoprotein, a type of cholesterol.
Procedure
LDL apheresis is a process similar to dialysis, where the patient's blood is circulated through a machine that removes the LDL cholesterol. The cleaned blood is then returned to the patient's body. This procedure is typically performed every two weeks and each session lasts approximately 2-4 hours.
Indications
LDL apheresis is indicated for patients with familial hypercholesterolemia or those who have not responded to diet and medication changes. It is also used for patients who cannot tolerate cholesterol-lowering medications.
Risks and Complications
Like any medical procedure, LDL apheresis carries some risks. These may include reactions to the anticoagulant used during the procedure, low blood pressure, and fatigue.
