Abstract:: Abstract: Objective To analyze the clinical features and computed tomography (CT) imaging features of peripheral arteriovenous malformations (AVM) in children, and to explore the value of CT enhanced examination before interventional therapy for peripheral AVM. Methods The clinical and imaging data of 47 children with peripheral AVM diagnosed by digital subtraction angiography were analyzed retrospectively, and the manifestations, including location, morphology, boundary, vascular architecture and bone invasion, were analyzed. Results The lesion was located at chest wall in 1 case, abdominal or pelvic wall in 3 cases, limbs in 7 cases, oral and maxillofacial region in 29 cases, aural region in 3 cases, orbit in 1 case, nose in 1 case, and scalp in 2 cases. Of 47 cases, 5 cases were accompanied with bone involvement. Peripheral AVM was characterized by high-flow vascular malformation, and symptoms were repeated or progressively aggravated. The specific CT signs included enhanced malformed vascular mass, large and distorted draining veins, and thick feeding arteries. Conclusion CT enhanced examination which can accurately display the malformed vessels, most of feeding arteries and draining veins is an effective evaluation method before interventional therapy.
