How Long Can A Molar Pregnancy Go Undetected?
A molar maternity is diagnose by an ultra sound scan . It is hard to diagnose molar maternity by the symptom and signs as these can be present even in other conditions . Usually most woman with molar gestation would not have symptom and most of the molar gestation would be find in the mundane date CAT scan which is done ordinarily within 8 hebdomad to 12 weeks . therefore , molar gestation can go undetected until about 12 weeks which is the first trimester . But sometimes if the womanhood does not cognize she is pregnant or if she does not take care the antenatal sojourn or do the dating scan or any other CAT scan and does not have any symptoms , molar pregnancy can go undetected until about 16 -20 weeks . It will be detected late when the other complications such as pregnancy inducedhypertension , preeclampsia , thyroid gland disease , thromboembolism occurs and by this time it would be too tardy .
Complete Molar Pregnancy
The diagnosis of complete molar pregnancy can be almost always made by an ultrasound scan . Earlier day the diagnosing made quite late and the molar maternity come along in the scan as the “ snowstorm pattern ” of the womb , however , this is not commonly fancy now as most of the molar pregnancies are identify at an earlier stage . The characteristic feature article seen in a complete molar maternity from an echography is a vesicular sonographic traffic pattern . This occurs because the chorionic villus proliferate with vacuolar swelling .
First trimester complete molar pregnancy appear as a complex and echogenic intrauterine mass hold many cystic spaces . Sometimes a large central fluid solicitation can be see which can be translate as an anembryonic gestation or abortion . Occasionally , there can be a central multitude with variable echogenicity because the villi are too small to be seen form the CAT scan during that period of time .
Studies have express that complete molar maternity can not be diagnose accurately by an ultras sound scan , therefore histological examination of the dispatch tissues is important to amount to an precise diagnosing . If histology is inconclusive DNA depth psychology of the remove tissue paper should be post out for a determinate diagnosing . Genetic marker psychoanalysis using polymerase chain reaction is accurate and very speedy in diagnose and classifying perfect and partial molar pregnancy . There is a 15 % of a ended molar gestation to go back in the future .
Partial Molar Pregnancy
It is difficult to distinguish partial grinder from all over molar pregnancy ; however , presence of fetal parts or retarded fetus is helpful in diagnosing fond molar from an ultrasonography CAT scan . The ultrasonic features of partial molar are enlarged or thickened placenta compared to the uterine sizing , cystic spaces within the placenta , an alive or dead well mould but deformed fetus , an empty gestational sac or a sac with an ill - defined foetal echo .
Similarly , in complete molar pregnancy it is not always possible to diagnose a partial grinder accurately from an ultrasound CAT scan , therefore histological examination of the remote tissue paper is authoritative . If histology is inconclusive desoxyribonucleic acid analysis of the off tissue paper should be carry out for a definitive diagnosing . Genetic marker analytic thinking using polymerase chain reaction is accurate and very speedy in diagnosing and separate utter and partial molar maternity . There is a 3 % of a fond molar gestation to recur in the future tense .
Conclusion
A molar gestation is diagnosed by an ultra sound scan . It is unmanageable to diagnose molar gestation by the symptom and sign as these can be present even in other conditions . unremarkably most women with molar pregnancy would not have symptoms and most of the molar pregnancy would be detect in the routine date scan which is done ordinarily within 8 weeks to 12 weeks . therefore , molar pregnancy can go undetected until about 12 weeks which is the first trimester . But sometimes if the woman does not know she is pregnant or if she does not attend the antenatal sojourn or do the dating scan or any other CAT scan and does not have any symptoms molar pregnancy can go undetected until about 16 to 20 calendar week .
