目的探讨超声联合CT检查对 宫外孕的临床价值。方法 回顾性分析 我院2016年1月-2017年1月来院产检的 110例宫外孕患者临床资料，将接受单 一腹部超声检查54例患者纳入对照组， 另56例接受腹部超声与CT联合检查的纳 入观察组。所有患者在超声、CT检查确 认为宫外孕后，均接受手术清除治疗， 切除组织送实验室检查。比较两组患者 宫外孕诊断正确率，并分析观察组患者 宫外孕CT、超声影像学特征。结果 对照 组实验室检查确诊为宫外孕有42例，比 例为77.78%，观察组实验室检查确诊为 宫外孕的患者有56例，比例为92.85%， 观察组宫外孕检查正确率高于对照组 (P<0.05)。宫外孕B超影像学显示，53例 子宫增大，膜层平均厚度(12.58±1.47) mm。51例子宫图像边缘欠清晰平均壁 厚(6.59±0.47)mm，其中48例中心区 无明显回声暗区。CT显示52例子宫右 前方出现椭圆形高密度灶，CT平均值 (56.59±1.48)HU。胎囊破裂51例，破裂 后胎囊变形无规则39例，胎囊周围高密 度积血10例。囊壁完整呈规则环形状8 例，半环形状6例，囊内结节萌芽9例， 囊内条状高密度血管7例，囊内斑片状高 密度19例。囊壁不规则增厚17例，胎囊 周边供应血管异常13例，盆腔积血7例， 输卵管积血4例。结论 产检医生可根据 CT征象结合超声图像特点判断宫外孕具 体情况，从而减少宫外孕误诊及漏诊 率，提高宫外孕诊断正确率。

Objective To investigate the clinical value of ultrasound combined with CT in ectopic pregnancy. Methods The clinical data of 110 patients with ectopic pregnancy who were admitted to our hospital from January 2016 to January 2017 in our hospital were retrospectively analyzed. 54 patients undergoing single abdominal ultrasonography were enrolled in the control group, and the other 56 patients underwent combined abdominal ultrasound and CT examination were included into the observation group. All patients were diagnosed as ectopic pregnancy through ultrasound and CT, and were treated with surgical removal, and the resected tissue was sent to the laboratory. The diagnostic accuracy of two groups was compared, and the CT and ultrasonic features of ectopic pregnancy were analyzed and observed. Results In the control group, 77.78% of ectopic pregnancy was diagnosed by laboratory examination, 92.85% of ectopic pregnancy was diagnosed by laboratory examination in the observation group, and the correct rate of ectopic pregnancy in the observation group was higher than that in the control group (P<0.05). Ectopic pregnancy B ultrasound showed 53 cases of uterine enlargement, 51 cases of uterine image edge is not clear average, 48 cases of central area without obvious echo dark area. CT showed oval high density foci, rupture of fetal sac in 51 cases, irregular deformation of fetal sac in 39 cases, high density hematocele around fetal sac in 10 cases, and tubal hematocele in 4 casesIn the control group, 42 cases were diagnosed as ectopic pregnancy, accounting for 77.78%. while 56 cases were diagnosed as ectopic pregnancy in the observation group, accounting for 92.85%. The correct rate of ectopic pregnancy in the observation group was higher than that of the control group (P<0.05). The ultrasound imaging of ectopic pregnancy showed that 53 cases of uterus enlarged and the average thickness of the membrane was (12.58±1.47) mm. In 51 cases, the edges of the uterus were not clear, the average wall thickness (6.59±0.47) mm, of which 48 cases, the central echo dark area was not obvious. Ovarian high density lesions appeared on the right front of the uterus in 52 cases, with a mean CT value of (56.59±1.48) HU. There were 51 cases of ruptured sac and 39 cases of ruptured sac and 10 cases of high density hemorrhage around fetal sac. There were 8 cases with regular ring shape, 6 cases with half-ring shape, 9 cases with intracapsular nodules, 7 cases with intracapsular high-density blood vessels and 19 cases with intracapsular high-density plaque. There were 17 cases of irregular thickening of the wall of the capsule, 13 cases of abnormal supply of blood vessels around the fetal capsule, 7 cases of pelvic hemorrhage and 4 cases of oviduct accumulation. Conclusion Obstetricians can judge the specific situation of ectopic pregnancy according to CT signs and ultrasonic image characteristics, so as to reduce the rate of misdiagnosis and missed diagnosis of ectopic pregnancy and improve the accuracy of diagnosis of ectopic pregnancy.According to the characteristics of CT imaging combined with ultrasound images of the doctor can determine the specific conditions of ectopic pregnancy, thereby reducing the misdiagnosis and misdiagnosis rate of ectopic pregnancy and improve the diagnostic accuracy of ectopic pregnancy.
