Teknisk gennemførlighedsundersøgelse af ultralydsmuskelbilleddannelse i antenatal ultralyd (FetUS)
Teknisk gennemførlighedsundersøgelse af ultralydsmuskelbilleddannelse i antenatal ultralydsscreening af medfødt multipel arthrogryposis
The objective of the study is to evaluate the performance of muscle ultrasound sections on antenatal ultrasound between 21-24 amenorrhea weeks for the screening of muscle atrophy, in a sample of low-risk and high-risk pregnancies of congenital multiple arthrogryposis

Detaljeret beskrivelse
Frequent rare diseases (100-200 births in France / year), congenital multiple arthrogryposis include a set of pathologies characterized by the limitation of joint movements at least two joint levels.Their functional prognosis and muscle atrophy are often severe after birth.
Routine ultrasound call signs are either non-specific or insensitive and difficult to detect due to time constraints. Antenatal ultrasound screening is not very effective for these pathologies, which are often particularly serious.
The main criterion will be the success rate of realization of all four ultrasound sections at the extremities (deltoide, biceps, quadriceps, triceps) and measurements of the distances "skin - muscle fascia" and "muscular fascia - periosteum" between 21-24 amenorrhea weeks

Concordance of measures (CCI coefficient) will be evaluated in intra-observer and inter-observer respectively
Tidsramme: 72 hours +/- 24 hours
|
Concordance of measures (CCI coefficient) will be evaluated in intra-observer and inter-observer respectively by dividing by half the high-risk pregnancies, to whom it will be proposed a 2nd ultrasound of the 2nd trimester, within 3 days (±24) hours by the same / another referent sonographer in the same center. A group of 30 low-risk pregnancies will be evaluated in the same way, with the study of intra-observer reproducibility in 15. The sample of 30 pregnancies in which two measurements are made makes it possible to obtain a lower bound of the 95% confidence interval of the intra-class correlation coefficient greater than 0.7, if this coefficient is 0.85 or more. This threshold is usually considered to reflect a satisfactory concordance. |
