Pediatric extremity multidetector computed tomographic angiography findings.
OBJECTIVE
To show results of pediatric extremity multidetector computed tomographic (MDCT) angiography studies and to demonstrate diagnostic imaging findings in pediatric patients.


METHODS
Multidetector computed tomographic angiography studies were performed in 20 patients using 16- and 64-row MDCT scanners. Three-dimensional volume-rendered and maximum-intensity projection images were obtained from axial images to display vascular structures.


RESULTS
All MDCT examinations were technically satisfactory. Metallic implants were present in 3 patients, and angiographic examinations were diagnostic in these patients. Occlusion, stenosis, and pseudoaneurysm were diagnosed in patients with trauma (n = 10). Vascular invasion was diagnosed in 1 patient with osteosarcoma. Compared with pathologic examination results, the sensitivity and specificity of MDCT to detect vascular invasion (n = 3) were both 100%. Three patients with vascular malformation underwent computed tomographic angiography to assess vascular supply of vascular malformations. Computed tomographic angiography showed vascular anatomy in 2 patients with congenital anomalies before and after flap transposition and in 1 patient with suspected thoracic outlet syndrome. Computed tomographic angiography showed brachial artery occlusion in a patient with Blalock-Taussing shunt.


CONCLUSIONS
Multidetector computed tomographic angiography is a noninvasive technique that could replace conventional angiography as the initial diagnostic study for vascular evaluation of extremities in pediatric patients.
