Aortocaval compression syndrome 
Summary
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]
