Insights

This case study details a complex aortic recoarctation in a 61-year-old patient with prior cardiac surgeries. An extra-anatomic bypass was successfully performed to address the recurrent aortic stenosis.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Surgery

Background:

  • A 61-year-old male with a history of two prior cardiac operations presented with symptoms suggestive of aortic re-stenosis.
  • The patient previously underwent repair of post-ductal coarctation of the aorta (CoA) with resection and end-to-end anastomosis at age 10.
  • Additionally, the patient had a mitral valve replacement with a mechanical prosthesis ten years prior due to severe mitral insufficiency.

Observation:

  • The patient was admitted due to recurrent symptoms indicative of aortic re-stenosis, specifically in the area of the previous coarctation repair.
  • Diagnostic evaluation confirmed significant re-stenosis at the site of the prior aortic coarctation repair.

Findings:

  • Surgical intervention involved the creation of an extra-anatomic bypass.
  • The bypass was constructed between the ascending aorta and the abdominal aorta.
  • The graft traversed a newly created diaphragmatic opening anterior to the right lung hilum.

Implications:

  • This case highlights the feasibility of extra-anatomic bypass for complex aortic recoarctation in patients with multiple previous sternotomies and thoracotomies.
  • The successful management of this challenging case demonstrates an alternative surgical strategy for recurrent aortic coarctation.
  • This approach may be considered for patients unsuitable for conventional re-operative aortic repair.
