arch reconstruction
Surgical repair of abnormalities affecting the aortic arch, often involving resection and end-to-end anastomosis or patch augmentation.
Full Definition
Arch reconstruction encompasses various surgical techniques used to repair abnormalities of the aortic arch in pediatric patients. These procedures may involve resection of coarctation segments with end-to-end anastomosis, patch aortoplasty using synthetic or biological materials, or more complex reconstructions for hypoplastic arch segments. The goal is to eliminate obstruction and provide adequate systemic blood flow while maintaining arch geometry that will grow appropriately with the patient. Techniques vary based on patient age, anatomy, and associated cardiac lesions. In neonates with complex lesions like hypoplastic left heart syndrome, arch reconstruction is typically performed as part of the Norwood procedure. Long-term follow-up is essential to monitor for recoarctation or arch re-stenosis.
Usage
Usage note: Specify technique used (end-to-end, patch, etc.) and whether performed in isolation or as part of complex procedure.
