摘要

摘要: 目的通过分析超声造影(CEUS)在剖宫产疤痕妊娠(CSP)诊断及治疗中的应用效果，以期为临床CSP诊治提供参考。方法回顾性收集2017年1月—2021年1月于嘉兴市第二医院就诊的80例疑似CSP患者的相关资料，术前均接受阴道超声、CEUS检查。以手术病理为金标准，对比阴道超声、CEUS对CSP的诊断效能，观察超声图像表现；对比CSP与非CSP患者超声造影时间-强度曲线(TIC)参数，并分析不同手术方式患者CEUS相关指标差异。结果 80例疑似CSP患者中，手术病理证实CSP 60例(75.00%)。手术病理作为金标准，CEUS诊断敏感度(96.67% vs. 86.67%)、准确度(93.75% vs. 83.75%)均明显高于阴道超声(P＜0.05)。60例CSP患者中，阴道超声显示突向包膜外18例，血流分级丰富型36例，孕囊型病灶46例；CEUS图像显示“面包圈”征55例。CSP患者造影开始增强时间、达峰时间均早于非CSP患者(P＜0.05)，峰值强度、增强速率均更大(P＜0.05)。腹腔镜手术患者CEUS指标孕囊/包块主要血供在疤痕处、绒毛膜/早期胎盘部位完全覆盖疤痕比例均大于超声下吸宫术/宫腔镜(P＜0.05)，疤痕厚度更小(Z=4.615，P < 0.001)。结论 CEUS对CSP诊断典型特征为“面包圈”征，相比阴道超声其诊断效能更大，且CEUS孕囊/包块主要供血部位等特征可能影响CSP治疗方式。

Abstract: Objective To examine the use of contrast-enhanced ultrasound (CEUS) for diagnosing and treating cesarean section scar pregnancy (CSP) providing a reference for clinical diagnosis and treatment of CSP. Methods The study retrospectively collected data from 80 suspected patients with CSP who were admitted to the Second Hospital of Jiaxing between January 2017 and January 2021. All patients underwent transvaginal ultrasonography and CEUS examination prior to surgery. The study compared the diagnostic efficacy of vaginal ultrasound and CEUS for CSP to surgical pathology, and observed the ultrasonographic manifestations; The parameters of contrast-enhanced ultrasound time-intensity curve (TIC) were compared between CSP and non-CSP patients, and the differences of CEUS related indexes in patients with different surgical methods were analyzed. Results Out of 80 patients suspected of having CSP, 60 cases (75.00%) were confirmed through operation and pathology. CEUS demonstrated significantly higher diagnostic sensitivity (96.67% vs. 86.67%) and accuracy (93.75% vs. 83.75%) compared to transvaginal ultrasound, which was considered the gold standard (P < 0.05). Out of 60 patients with CSP, 18 cases exhibited extravasation, 36 cases showed rich blood grading, and 46 cases showed gestational cystic lesions; The CEUS images revealed a "bagel" sign in 55 cases. The onset and peak times of angiography in patients with cerebral small vessel disease (CSVD) were earlier than those in patients without CSVD (P < 0.05), Additionally, the peak intensity and rate of enhancement were greater in patients with CSVD (P < 0.05). The proportion of the major blood supply to the gestational sac/mass in the scar and the chorionic membrane/early placenta completely covering the scar was found to be higher in laparoscopic surgery than in ultrasound/hysteroscopy (P < 0.05), Additionally, the scar thickness was smaller in laparoscopic surgery (P < 0.05). Conclusion CEUS is typically characterized by the "bagel" sign in the diagnosis of CSP, which has greater diagnostic efficacy than transvaginal ultrasound, Additionally, the characteristics of the main blood supply site of CEUS pregnancy sac/mass may affect the treatment of CSP.
