Superior Mesenteric Artery Syndrome
Conditions
Brief summary
Multicenter, prospective, observational research project on children aged from 10 to 15 years old undergoing abdominal ultrasound examinations during routine clinical practice.
Detailed description
Demographics data, clinical indications, ultrasound diagnosis, and ultrasound measurements will be recorded and stored on an database. Ultrasound measurements will be analyzed to define the normal range of values of Superior Mesenteric Artery (SMA) angle and Superior Mesenteric Artery - Aorta (SMA-A) distance in the pediatric population according to age, Body Mass Index (BMI), and fat parameters.
Interventions
DIAGNOSTIC_TESTUltrasound measurements
ultrasound measurement at the level of the left renal vein on a sagittal plane according to age

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Define the normal range of values of the SMA angle | 1 day | Measurement in degree with its 95% confidence interval |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Define the normal range of values of the SMA-A distance LV | 1 day | Measurement in millimeter (mm) with its 95% confidence interval measured through ultrasound examination at the level of the left renal vein on an axial plane according to age |
| Define the normal range of values of the SMA-A distance D | 1 day | Measurement in millimeter (mm) with its 95% confidence interval measured through ultrasound examination at a level where the third part of the duodenum crosses on an axial plane according to age |
| Define the normal range of values of the SMA angle (degree), SMA-A distance LV | 1 day | Measurement in millimeter (mm) with its 95% confidence interval measured through ultrasound examination according to BMI categories, subcutaneous and visceral fat thickness |
| Assess the association between the SMA angle and BMI categories | 1 day | According to age and sex. |
