Abstract
OPTIONS for the treatment of thoracoabdominally conjoined twins are largely dependent on the anatomy of the cardiovascular system.1 2 3 The extent of the conjunction of the heart and the severity of the associated cardiac defects primarily determine the feasibility of successful separation of the infants. Typically, the cardiovascular system is investigated first in the evaluation of thoracoabdominally conjoined twins. Only if the condition of the heart and associated structures is suitable for separation are the other organ systems, such as the gastrointestinal and urinary tracts, investigated.Definition of the cardiovascular anatomy in utero would facilitate prenatal counseling and perinatal management.
