Abstract
Aim
Conjoined twins is one of the rare congenital complex malformation,In this paper, on the basis of literature review, head of a rare twins parasitic twin anatomy of system analysis,In order to couplet body parasitic twin anatomy compiled to provide more information.
Materials and methods
On a rare head twins parasitic foetus to analyze systematic anatomy, observe its body surface and viscera variation characteristics, and prenatal ultrasound, CT three reconstruction results after induced labor, by contrast, at the same time the systematic review of the literature of couplet of deformity at home and abroad, summarizes the particularity of the case.
Results
Conjoined twins can be divided into the head, the chest and the abdomen, even back, even a variety of forms such as hip sacral, among them, the chest and the abdomen, the buttocks sacral is the most common and most conjoined twins for symmetry, but in this case the fetus asymmetry, twins conjoined at the head, chest, the nervous system, respiratory system, urinary system and digestive system are significant abnormalities, including structure of cardiovascular malformation has yet to see the same reports at home and abroad.
Conclusion
Conjoined twins anatomy variation has the characteristics of pleomorphic, complexity and specificity.To this kind of rare, more complex system during pregnancy joint deformity noninvasive and accurate diagnosis is crucial, conjoined fetal growth of system structure and function is to determine whether the surgery treatment and evaluate the key of the surgical risk.Super living screening fetus during pregnancy is the
conjoined noninvasive diagnostic method of choice for the fetus.This paper further enrich the conjoined twins anatomical characteristics especially cardiovascular structure variation of data, for the joint deformity of prenatal diagnosis and clinical research provides more information applied anatomy.。
