Abstract

Objectives: To assess fetal proximal and distal transverse aortic arch and aortic isthmus (AI) diameters between 19 and 34 weeks of gestation.

Methods: A prospective cross-sectional descriptive study was performed in 466 low-risk pregnancies between 19 and 34 weeks of gestation. Proximal transverse aortic arch (PTAA), distal transverse aortic arch (DTAA), and the AI diameters (sagittal and three-vessel trachea view) were measured.

Results: The mean ± SD, and 5th, 50th, 95th centile charts according to gestational age for PTAA, DTAA, and AI diameter were constructed. Pearson's correlation coefficients for PTAA, DTAA, and AI diameter (sagittal and three-vessel trachea view) by gestational week were 0.884, 0.877, 0.890, and 0.898, respectively (P < .0001). The mean AI diameter, in both sagittal and three-vessel trachea planes, was significantly lower than that of the proximal and distal transverse aortic arch (P = .001).

Conclusions: We demonstrated the growth curve and nomogram of the PTAA. With the aid of nomograms, the prenatal identification of proximal transverse aortic arch hypoplasia may facilitate a better understanding of the severity of transverse aortic arch hypoplasia and assist in planning the appropriate postnatal surgical intervention.

妊娠19 ~ 34周胎儿近端和远端主动脉弓横向和主动脉峡测量。

目的：评估胎儿近端和远端主动脉弓和主动脉峡（AI）直径在妊娠19至34周。方法：对466例19 ~ 34周的低危妊娠进行前瞻性横断面描述性研究。测量近端主动脉弓（PTAA）、远端主动脉弓（DTAA）和AI直径（矢状面和三血管气管视图）。结果：构建了PTAA、DTAA和AI直径按胎龄的平均值±SD和第5、50、95百分位图。PTAA、DTAA和AI直径（矢状面和三血管气管面）随妊娠周的Pearson相关系数分别为0.884、0.877、0.890和0.898 (P)。在x线图的帮助下，产前识别近端主动脉弓横断面发育不全可以更好地了解主动脉弓横断面发育不全的严重程度，并有助于计划适当的产后手术干预。

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
