This third edition of "Practical Guide to High-Risk Pregnancy and Delivery" has been completely revised to present a more up-to-date approach to the field. Several changes have been made in the book to keep up with multiple new developments and to facilitate the findings of information. The purpose of the book remains unchanged: to provide residents/trainees in Obstetrics and Gynecology, fellows in Maternal-Fetal Medicine, obstetricians, general physicians, and interested nurses and medical students with a source of practical information about complications of pregnancy.
