Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Grafting

Background:

  • Aortic arch replacement is a complex procedure.
  • Achieving a physiologic neoaorta shape after hemiarch replacement can be challenging.
  • Standard techniques may lead to suboptimal graft configurations.

Purpose of the Study:

  • To present a new graft tailoring method for hemiarch replacement.
  • To address the challenges of creating a physiologic neoaorta with a right angle between the arch and ascending aorta.
  • To avoid kinks in the distal anastomosis.

Main Methods:

  • A modified superior beveling technique for the distal graft end.
  • Utilizing a curvilinear incision to create a concave cut end.
  • Straightening the concavity post-anastomosis to form the lesser curvature of the aortic arch.

Main Results:

  • The described technique accommodates long elliptical distal anastomoses.
  • It successfully creates a right angle between the arch and ascending aorta without kinking.
  • The method results in a more physiologic shape of the neoaorta.

Conclusions:

  • This graft tailoring method offers an effective solution for hemiarch replacement.
  • It facilitates the creation of a more anatomically correct neoaorta.
  • The technique enhances surgical precision and patient outcomes in aortic reconstruction.
