Vascular rings

Vascular rings : Abnormalities in the resolution of the double aortic arch system, present in fetal life, can give rise to anomalies of the aortic arch and its branches, which can compress the trachea and esophagus. This group usually includes under the name of vascular rings.

Vascular rings

There are 3 types:

  • The double aortic arch.
  • The aorta on the right with a ductus arteriosus on the left.
  • The retroesophageal right subelavian artery.

Diagnosis

The vascular rings can be asymptomatic or lead to symptoms from compression of the airway or esophagus, causing dyspnea or dysgestive symptoms (the so-called lusory dysphagia).

Bone scan

  • Telecardiogram:
    • Suggestive image of the vascular ring by compression between the upper third and the middle third of the esophagus, in the right anterior view.
  • Esophagogram:
    • Oblique filling defect at the site of the esophagus, mentioned above, caused by compression of the abnormal vessel.
  • Contrast arthritis:
    • The presence of the abnormal vessel is checked.

Treatment

Operative indication.

  • It should be operated as soon as the [diagnosis] is made.

Operative technique.

  • Almost all of these patients can be treated by left posterolateral thoracotomy, performed through the 3rd. intercostal space, without rib resection.

Double aortic arch.

  • The anterior or left arch is usually the smaller of the two and originates the left subclavian artery, the carotid artery, or the right subclavian artery.
  • If the subclavian artery is the only branch of the minor or left arch, the annulus is interrupted by dividing the left arch between the place of origin of the subclavian artery and the junction of the left arch with the descending thoracic aorta.

Postoperative recovery time

They will be granted between 45 days-60 days, from the final registration.
