Ультразвуковая диагностика спонтанного тромбоза артерии пуповины

Вы можете загрузить полный текст статьи в формате pdf

В статье описаны 7 случаев спонтанного тромбоза артерии пуповины и 3 случая тромбоза, связанного с внутриутробными вмешательствами (внутриутробное внутрисосудистое переливание крови плоду). 6 из 7 случаев спонтанного тромбоза артерии пуповины подтверждены морфологически. Тромбоз артерии пуповины сопровождается уменьшением диаметра артерии. Со временем артерия превращается в структуру повышенной эхогенности или становится изоэхогенной вартонову студню. В этом случае обнаруживается “исчезновение” одной из артерий. Диаметр оставшейся артерии увеличивается. С учетом особенностей эмбриогенеза сделаны выводы о необходимости тщательного изучения корня пуповины, свободных петель, области пупочного кольца, активного поиска аномалий пуповины, что важно для своевременной диагностики острых расстройств кровообращения в пуповине.

Ключевые слова:
пренатальная ультразвуковая диагностика, тромбоз артерии пуповины, допплерография плода, внутри/ утробная задержка развития, фетальная тромботическая ангиопатия.

Spontaneous Umbilical Artery Thrombosis Ultrasound Diagnostics

In the article 7 cases of umbilical artery spontaneous thrombosis and 3 cases of thrombosis associated with intrauterine intravascular hemotransfusion were described. 6 of 7 umbilical artery spontaneous thrombosis cases were confirmed morphologically. Umbilical artery thrombosis was accompanied by artery diameter decrease. With the lapse of time the umbilical artery have becoming hyperechoic or isoechoic to Wharton's jelly. In this case one of the arteries has “disappeared”. The diameter of another artery was increasing. Taking into consideration the embryogenesis peculiarities conclusions were made: it is necessary thoroughly investigate the umbilical root, free loops, umbilical ring region for well-timed umbilical blood flow disorders diagnosis.
