First trimester pregnancy is defined as twelve weeks after the last menstrual period. Ultrasonography has revolutionized validation and management of first trimester pregnancies. The aim was to analyze ultrasonographic findings of first trimester pregnancies in University of Uyo teaching hospital (UUTH), Uyo, Nigeria.
The departmental ultrasonographic records of pregnant women who were referred to Radiology department of UUTH, Uyo, Nigeria. For ultrasound scans were retrospectively reviewed. The period under consideration was from 8 January 2013 to 8 February, 2016. Demographic data and ultrasonographic parameters of first trimester pregnancies like gestational sacs were recorded. Data were statistically analyzed using SPSS Chicago 13. Exclusion criterion included incomplete data and acyesis despite positive βhCG test.
26.4% (n-645) of the 2438 pregnant women who underwent obstetric ultrasonography had first trimester ultrasonography during the studied period. The peak frequency was seen in the 20-29 age range with 52.2% (n-337) and followed by 30-39 age range with 41.7% (n-269). The commonest first trimester ultrasound findings was viable pregnancy with 42.5% (n-274), followed by incomplete miscarriage with 34.3% (n-221). The least finding was trophoblastic pregnancies 0.3% (n-2). The earliest age at which normal viable pregnancy was diagnosed in this study was 5weeks 5days from the last menstrual period. Only 2.19% (n-6) of the normal viable pregnancies were multiple pregnancies and they were all twins. The highest number of referrals to Radiology Department for first trimester ultrasonography was from accident and emergency unit with 34.42% (n-222) while antenatal clinic referral was only 16.12% (n-104).
The commonest first trimester's obstetric ultrasonographic findings in Uyo, Nigeria are viable pregnancies and are predominantly single gestation. The earliest age of ultasonographic pregnancy detection in Uyo is 5week 5days and peak maternal age is second and third decades.
孕早期被定义为末次月经后12周。超声检查彻底改变了孕早期妊娠的确认和管理方式。本研究旨在分析尼日利亚乌约大学教学医院（UUTH）孕早期妊娠的超声检查结果。
回顾性分析转诊至尼日利亚乌约UUTH放射科的孕妇的科室超声检查记录。研究时间段为2013年1月8日至2016年2月8日。记录孕早期妊娠的人口统计学数据和超声参数，如妊娠囊。使用SPSS Chicago 13对数据进行统计分析。排除标准包括数据不完整以及β-hCG检测呈阳性但未妊娠。
在接受产科超声检查的2438名孕妇中，26.4%（n = 645）在研究期间进行了孕早期超声检查。高峰频率出现在20 - 29岁年龄组，占52.2%（n = 337），其次是30 - 39岁年龄组，占41.7%（n = 269）。孕早期最常见的超声检查结果是活胎妊娠，占42.5%（n = 274），其次是不全流产，占34.3%（n = 221）。最少见的是滋养细胞妊娠，占0.3%（n = 2）。本研究中诊断出正常活胎妊娠的最早年龄是末次月经后5周5天。正常活胎妊娠中只有2.19%（n = 6）是多胎妊娠，且均为双胞胎。因孕早期超声检查转诊至放射科人数最多的是急诊科，占34.42%（n = 222），而产前门诊转诊仅占16.12%（n = 104）。
在尼日利亚乌约，孕早期最常见的产科超声检查结果是活胎妊娠，且主要为单胎妊娠。乌约超声检查发现妊娠的最早年龄是5周5天，孕妇年龄高峰在二三十岁。
