Twin-to-Twin Transfusion Syndrome (TTTS) is a rare condition that only occurs in identical twins when they are in the womb. It occurs when blood moves from one twin to the other, resulting in one twin having too little blood and the other with too much blood. This concise guide describes the etiology, diagnosis and treatment of TTTS. Divided into six sections, the book begins with the history of the condition, then the basics, clinical features and diagnosis, to the most recent advances in its management and related ethical issues.
