Aortocaval compression syndrome

Aortocaval Compression Syndrome

Aortocaval Compression Syndrome (pronunciation: ay-or-toh-kay-vuhl kuhm-presh-uhn sin-drohm), also known as Supine Hypotensive Syndrome, is a medical condition primarily observed in pregnant women, particularly during the third trimester.

Etymology

The term "Aortocaval Compression Syndrome" is derived from the words 'aorta' and 'vena cava', which are the two major blood vessels that can be compressed in this condition, and 'syndrome', which refers to a group of symptoms that consistently occur together.

Definition

Aortocaval Compression Syndrome occurs when the enlarged uterus in late pregnancy compresses the inferior vena cava and the aorta when the pregnant woman lies on her back, causing a significant reduction in cardiac output, and potentially leading to maternal and fetal hypotension.

Symptoms

The symptoms of Aortocaval Compression Syndrome include nausea, dizziness, sweating, palpitations, and in severe cases, unconsciousness.

Prevention and Management

The syndrome can be prevented and managed by avoiding the supine position during pregnancy, especially in the third trimester. Left lateral tilt position is recommended during surgical procedures to prevent this syndrome.
