Siamese Twins Meaning By Medical
Siamese twins meaning is identical twins that still have body parts connected. This condition is three times more common in infant girls than in male infants.
The cause behind conjoined twins is not known for certain. Experts suspect there are two theories that may trigger this condition, namely:
Immature cleavage on a fertilized egg cell. The process of dividing an egg into two typically occurs at eight to 12 days after the egg cell meets the sperm. If the cleavage takes place over this period of time, the division tends to stop before the process is complete.
The two embryos that were originally separated back stuck together.
Types of Siamese Twins
Body parts connected to conjoined twins vary. This difference is the benchmark in determining the type of conjoined twins.
Chest is the most commonly connected body part of most conjoined twins. But conjoined twins also have the possibility to connect in other body parts, such as the abdomen, spine, pelvis, or even the head.
In addition to several types of conjoined twins above, there is one type known as parasitic conjoined twins. This is the condition in which one of the twin babies is smaller and the physical is not perfectly formed.
The process of Diagnosis and Handling of Siamese Twins
The possibility of conjoined twins in the fetus can be known through standard ultrasound examinations since the first trimester. To see the extent to which twins are connected and how their organs perform, more sophisticated examinations during the second trimester, such as more detailed ultrasound, echocardiogram, and MRI scan are performed.
During pregnancy, mothers conjoined twins will undergo careful monitoring by the doctor until delivery. The process of delivery to be undertaken is a cesarean section. This operation will usually be planned before the date of birth. For example, at two weeks to one month before the due date of birth.
In addition to the difficult birth process, conjoined twins also have a low chance of life. Most conjoined twins tend to lose their lives at birth or shortly thereafter.
A few surviving conjoined twins have the opportunity to undergo separation surgery. However, this operation includes high-risk and dangerous procedures.
The degree of difficulty of the separation procedure to be performed is certainly not the same for each pair of conjoined twins. This difference depends on what part of the body and the internal organs in which it is fused, as well as the health condition of both infants. The expertise of the surgeon team will also be an important key in determining the success of the surgical procedure. In addition, the surgeon’s team should also think about what reconstructive surgery might need to be done if the surgery is successful.
