BACKGROUND/AIM: The presented study aimed to evaluate the utility of magnetic resonance angiography (MRA) in the pediatric population with nutcracker syndrome.
Patients with suggestive clinical symptoms and laboratory findings and got the diagnosis of nutcracker syndrome with Doppler ultrasonography between January 2011–2019 were included in the study. In addition, children who had renal MRA due to hypertension were evaluated as the control group. MRA images of all patients were examined retrospectively by three radiologists at different levels of experience, and the superior mesenteric artery angle, aorta-mesenteric distance, left renal vein diameter both in the regions of aorta-mesenteric, and renal hilum were recorded.
Forty-five patients diagnosed with nutcracker syndrome were included in the study. The mean age of patients was 12 (4–16) and 30 (67%) were female. As the control group, 25 patients with hypertension who had MRA were included and they had a mean age of 12 (1–18) and 19 (76%) were male. The mean superior mesenteric artery angle was 26.5 ° (16–73 ± 12) in the patient group and 57.8 ° (25–139, ± 33) in the control group (p < 0.001); the mean aorta-mesenteric distance was 3.3 mm (1.7–6.5, ± 1.1) in the patient group and 8 mm (3.4–32, ± 5.9) in the control group (p < 0.001). MRA measurements of three radiologists were consistent with each other.
MRA imaging can be applied as an alternative diagnostic method for Doppler ultrasonography and multidetector CT examinations by radiologists with different experience levels in pediatric patients with nutcracker syndrome.
背景/目的：本研究旨在评估磁共振血管造影（MRA）在儿童胡桃夹综合征中的应用价值。
本研究纳入了 2011 年 1 月至 2019 年期间因多普勒超声检查提示临床症状和实验室检查结果且诊断为胡桃夹综合征的患者。此外，因高血压行肾 MRA 的患儿被评估为对照组。所有患者的 MRA 图像均由三位不同经验水平的放射科医生进行回顾性检查，并记录肠系膜上动脉夹角、腹主动脉-肠系膜距离、主动脉-肠系膜区域和肾门处左肾静脉直径。
本研究纳入了 45 例确诊为胡桃夹综合征的患者。患者的平均年龄为 12 岁（4-16 岁），其中 30 例（67%）为女性。作为对照组，纳入了 25 例因高血压而行 MRA 的患儿，他们的平均年龄为 12 岁（1-18 岁），其中 19 例（76%）为男性。患者组肠系膜上动脉夹角的平均角度为 26.5°（16-73 ± 12），对照组为 57.8°（25-139，± 33）（p < 0.001）；患者组腹主动脉-肠系膜距离的平均距离为 3.3 毫米（1.7-6.5，± 1.1），对照组为 8 毫米（3.4-32，± 5.9）（p < 0.001）。三位放射科医生的 MRA 测量结果相互一致。
对于儿童胡桃夹综合征患者，MRA 成像可以作为多普勒超声和多层螺旋 CT 检查的替代诊断方法，不同经验水平的放射科医生均可应用。
