Abstract

Objective

This study aimed to assess the use of two-dimensional (2D) ultrasound combined with high-definition flow (HD-flow) render mode and spatiotemporal image correlation (STIC) in diagnosing and classifying fetal persistent left superior vena cava (PLSVC).

Methods

Overall, 114 cases of fetal PLSVC were diagnosed using 2D ultrasound combined with STIC, and 114 normal fetuses of the same gestational week were selected. These cases were retrospectively analyzed to evaluate the effectiveness of the diagnostic approach.

Results

All 114 PLSVC cases were diagnosed using 2D ultrasound combined with STIC. Although the diagnostic coincidence rate of PLSVC in the HD-flow combined with STIC was similar to that in the 2D ultrasound combined with HD-flow (96.8 vs 96.2%), 2D ultrasound with STIC enabled dynamic visualization of the PLSVC, furthering prenatal diagnosis. These cases were classified as type I PLSVC: 80 cases of type Ia, 29 cases of type Ib, and 5 cases of type Ic. Seventy isolated PLSVC cases (61.4%) were noted, whereas 44 cases (35.6%) were associated with concomitant structural abnormalities. Intracardiac structural malformations accounted for the highest proportion (n = 53, 58.89%), followed by single umbilical artery and facial/bodily abnormalities (n = 10, 11.11%).

Conclusion

Combining HD-flow and STIC complements 2D ultrasound in diagnosing and classifying fetal PLSVC, demonstrating significant clinical relevance.

利用高清血流渲染模式和时空图像相关性对持续性左上腔静脉进行产前诊断

研究目的该研究旨在评估二维（2D）超声结合高清血流（HD-flow）渲染模式和时空图像相关（STIC）在胎儿持续性左上腔静脉（PLSVC）诊断和分类中的应用：方法：使用二维超声结合 STIC 诊断了 114 例胎儿持续性左上腔静脉（PLSVC），并选择了 114 例相同孕周的正常胎儿。对这些病例进行回顾性分析，以评估诊断方法的有效性：结果：所有114例PLSVC病例都是通过二维超声结合STIC诊断出来的。虽然高清血流联合 STIC 的 PLSVC 诊断吻合率与二维超声联合高清血流相似（96.8% vs 96.2%），但二维超声联合 STIC 可动态观察 PLSVC，从而进一步提高产前诊断的准确率。这些病例被分为 I 型 PLSVC：80 例 Ia 型、29 例 Ib 型和 5 例 Ic 型。其中 70 例（61.4%）为孤立的 PLSVC，44 例（35.6%）伴有结构异常。心内结构畸形所占比例最高（53 例，58.89%），其次是单脐动脉和面部/体型异常（10 例，11.11%）：结论：结合高清血流和 STIC 可补充二维超声诊断和分类胎儿 PLSVC，具有重要的临床意义。

期刊介绍： The Journal of Ultrasound in Medicine (JUM) is dedicated to the rapid, accurate publication of original articles dealing with all aspects of medical ultrasound, particularly its direct application to patient care but also relevant basic science, advances in instrumentation, and biological effects. The journal is an official publication of the American Institute of Ultrasound in Medicine and publishes articles in a variety of categories, including Original Research papers, Review Articles, Pictorial Essays, Technical Innovations, Case Series, Letters to the Editor, and more, from an international bevy of countries in a continual effort to showcase and promote advances in the ultrasound community. Represented through these efforts are a wide variety of disciplines of ultrasound, including, but not limited to: -Basic Science- Breast Ultrasound- Contrast-Enhanced Ultrasound- Dermatology- Echocardiography- Elastography- Emergency Medicine- Fetal Echocardiography- Gastrointestinal Ultrasound- General and Abdominal Ultrasound- Genitourinary Ultrasound- Gynecologic Ultrasound- Head and Neck Ultrasound- High Frequency Clinical and Preclinical Imaging- Interventional-Intraoperative Ultrasound- Musculoskeletal Ultrasound- Neurosonology- Obstetric Ultrasound- Ophthalmologic Ultrasound- Pediatric Ultrasound- Point-of-Care Ultrasound- Public Policy- Superficial Structures- Therapeutic Ultrasound- Ultrasound Education- Ultrasound in Global Health- Urologic Ultrasound- Vascular Ultrasound
