title: Successful management of severe aortocaval compression in twin pregnancy.
abstract: In a patient with severe aortocaval compression, simultaneous brachial and femoral blood pressure measurements demonstrated the need for a 30 degrees left-down tilt to avoid significant obstruction of the vessels. When emergency cesarean section became necessary, proper positioning of the patient was readily accomplished.
