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]
