Specialty	Obstetrics and gynaecology

Aortocaval compression syndrome, also known as supine hypotensive syndrome, is compression of the abdominal aorta and inferior vena cava by the gravid uterus when a pregnant woman lies on her back, i.e. in the supine position. It is a frequent cause of low maternal blood pressure (hypotension), which can result in loss of consciousness^[1] and in extreme circumstances fetal demise.^[2]^[3]

Signs and symptoms

Aortocaval compression syndrome may cause syncope, restlessness, dizziness, headache, tinnitus, visual disturbances, numbness or paresthesia of the limbs, abdominal/chest discomfort or pain, nausea, and vomiting.^[4] Some patients may be asymptomatic.^[5]
