Aortic Dissection in Pregnancy
Khalid Mansour Abdel Gawad Ibrahim;
Abstract
Pregnancy is associated with significant physiological cardiovascular changes to meet the increased metabolic demands of the mother and fetus and to ensure adequate uteroplacental circulation for fetal growth and development.
From mid-pregnancy the enlarging uterus compresses both the inferior vena cava and the lower aorta when the patient lies supine. Compression of the inferior vena cava reduces venous return to the heart leading to a fall in pre-load and cardiac output. The fall in blood pressure may be severe enough for the mother to lose consciousness. Compression of the aorta may lead to a reduction in uteroplacental and renal blood flow. During the last trimester, maternal kidney function is markedly lower in the supine than in the lateral position. Furthermore, foetal transplacental gas exchange may be compromised. For these reasons no woman should li
