Digital subtraction angiography in children
Insights
Digital subtraction angiography is an excellent and diagnostic screening tool for pediatric vascular abnormalities. This outpatient procedure is effective for evaluating various vessels in children, using short catheters for contrast delivery.
Area of Science:
- Pediatric radiology
- Vascular imaging
- Interventional radiology
Background:
- Digital subtraction angiography (DSA) is a valuable imaging technique.
- Evaluating vascular abnormalities in pediatric patients presents unique challenges.
- Non-invasive or minimally invasive imaging is preferred for children.
Observation:
- Preliminary results indicate DSA is an excellent screening and diagnostic procedure in infants and children.
- The examination can be successfully performed on outpatients.
- Sixty pediatric patients underwent DSA for suspected abnormalities of the aortic arch, intracranial, pulmonary, abdominal, and peripheral vessels.
Findings:
- Adequate sedation is crucial to prevent motion artifacts.
- Short catheters placed in an antecubital vein are satisfactory for contrast material delivery in pediatric patients.
- DSA effectively visualizes a wide range of pediatric vascular structures.
Implications:
- DSA offers a reliable method for diagnosing pediatric vascular diseases.
- Outpatient-based DSA can improve accessibility and reduce healthcare costs for pediatric patients.
- The findings support the expanded use of DSA in pediatric vascular imaging.
Abstract:
Preliminary results with digital subtraction angiography in infants and children have shown this to be an excellent screening procedure and often diagnostic. The examination can be performed satisfactorily on outpatients. Sixty patients have undergone this examination for evaluation of suspected abnormalities of the aortic arch and its branches, intracranial arteries, pulmonary arteries, abdominal aorta and its branches, and peripheral vessels. Adequate sedation is mandatory to prevent motion artifacts. While the literature reports increasing use of central venous catheters for delivery of contrast material, the use of short catheters placed in an antecubital vein is satisfactory for the pediatric patient. Techniques of the procedures are described along with seven appropriate case examples.
