Trends in vascular ring surgery

At our institution, computed tomographic scanning has replaced barium swallow as the diagnostic procedure of choice for vascular ring evaluation. We recommend both preoperative bronchoscopy and echocardiography. Use of a muscle-sparing thoracotomy without routine chest drainage has decreased mean hospital stay. For patients with a right aortic arch and associated Kommerell diverticulum, we recommend diverticulum resection with left subclavian artery transfer to the left carotid artery.
