Causes And Risk Factors Linked To Avascular Necrosis

Fatty Deposits In Blood Vessels

Fatty deposits in blood vessels can impede proper blood circulation and increase the likelihood of avascular necrosis. Typically, fatty deposits are made of cholesterol, and these deposits often lead to atherosclerosis, a hardening and stiffening of the arteries. Patients with high cholesterol, diabetes, obesity, and high blood pressure are more likely to have fatty deposits in their blood vessels. These deposits may break apart and block smaller blood vessels, and they can also form dangerous clots that cut off blood flow to major vessels. To check for the presence of these deposits, doctors can perform ultrasounds and other advanced imaging studies. If deposits are found, patients may need to take medications to lower cholesterol and blood pressure, and they may also need to make lifestyle modifications and lose weight. In particular, reducing saturated fat and trans fat in the diet can cut down on the fatty deposits present in the vessels. Occasionally, surgical intervention can be used to remove some deposits; this depends on which particular vessels are blocked.
