Summary

Parallel and chimney grafts are increasingly used for aortic arch lesions due to graft shortages. While promising, high rates of type I endoleaks and neurological complications remain significant concerns.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Endovascular Repair

Background:

  • Shortage of off-the-shelf aortic arch grafts necessitates alternative solutions.
  • Parallel grafts and chimney grafts are increasingly utilized for aortic arch lesions.
  • Existing techniques face challenges with type I endoleaks and graft-to-graft sealing.

Purpose of the Study:

  • To evaluate the outcomes of using Medtronic thoracic grafts with long self-expanding parallel grafts for aortic arch repair.
  • To assess the efficacy and safety of parallel and chimney graft configurations in complex aortic arch interventions.

Main Methods:

  • Retrospective analysis of 65 parallel grafts placed into supra-aortic branches.
  • Utilization of chimney grafts in the carotid (21 cases) and left subclavian arteries (36 cases).

  • Application of sandwich configurations and ensuring >7 cm overlap between grafts.

    • Main Results:

    • Patency rates were 69% for subclavian artery chimney grafts and 73% for carotid artery parallel grafts.
    • A stroke rate of 5.2% was observed.
    • Primary type I endoleak rate was 28%, with 25% requiring secondary interventions.

    Conclusions:

    • Parallel and chimney grafts offer a viable endovascular solution for aortic arch lesions.
    • High rates of type I endoleaks and neurological complications require further investigation and optimization.
    • Further research is needed to mitigate risks and improve sealing in complex aortic arch interventions.
