To determine the prevalence of simple ovarian cysts of >or= 3 cm diameter detected by transvaginal sonography (TVS) in a population of asymptomatic women in early pregnancy.
We conducted a retrospective review of 10,830 consecutive women presenting prior to 14 weeks' gestational age (GA) for early dating TVS. The records of all women with simple cysts >or= 3 cm in diameter were included. The study population was divided into five groups by GA: >or= 6 weeks; 6.1-8 weeks; 8.1-10 weeks; 10.1-12 weeks; and 12.1-14 weeks.
A simple cyst >or= 3 cm in diameter was present in 4.9% of women at >or= 6 weeks' gestation, in 5.1% between 6.1 and 8 weeks, in 5.3% between 8.1 and 10 weeks, in 3.2% between 10.1. and 12 weeks, and in 1.5% between 12 and 14 weeks. Overall, a simple cyst >or= 3 cm was present in 516 women (4.8%). Prior to 10 weeks, 5.1% had simple cysts >or= 3 cm, dropping to 2.7% after 10 weeks, a statistically significant decrease (P<0.0001). Between 10.1 weeks and 12 weeks, the prevalence dropped to 3.2%, and then to 1.5% in the 12.1-14 week group.
This investigation provides reference data on the prevalence of detecting simple ovarian cysts >or= 3 cm by TVS in an asymptomatic early pregnancy population. A progressive decline in the frequency of detecting simple ovarian cysts >or= 3 cm begins after 10 weeks' gestational age.
确定经阴道超声检查（TVS）在早孕无症状女性人群中检测到直径≥3 cm单纯性卵巢囊肿的患病率。
我们对10830例妊娠14周前因早期孕周测定行TVS检查的连续女性进行了回顾性研究。纳入所有直径≥3 cm单纯性囊肿女性的记录。研究人群按孕周分为五组：≥6周；6.1 - 8周；8.1 - 10周；10.1 - 12周；以及12.1 - 14周。
妊娠≥6周的女性中，4.9%存在直径≥3 cm的单纯性囊肿；6.1至8周之间为5.1%；8.1至10周之间为5.3%；10.1至12周之间为3.2%；12至14周之间为1.5%。总体而言，516名女性（4.8%）存在直径≥3 cm的单纯性囊肿。孕10周前，5.1%有直径≥3 cm的单纯性囊肿，10周后降至2.7%，差异有统计学意义（P<0.0001）。在10.1周至12周之间，患病率降至3.2%，然后在12.1 - 14周组降至1.5%。
本研究为无症状早孕人群经TVS检测直径≥3 cm单纯性卵巢囊肿的患病率提供了参考数据。孕10周后，直径≥3 cm单纯性卵巢囊肿的检出频率开始逐渐下降。
