Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Surgical Techniques

Background:

  • Achieving proximal anastomosis hemostasis is critical in ascending aorta replacement.
  • Conventional prosthesis eversion techniques may have limitations in ensuring hemostasis.
  • A modified technique was developed to address these challenges.

Purpose of the Study:

  • To describe a modified prosthesis eversion technique for proximal anastomosis in ascending aorta replacement.
  • To compare the operative outcomes of the modified technique with the conventional technique.

Main Methods:

  • Retrospective analysis of 108 patients undergoing ascending aorta replacement.
  • Comparison between a modified prosthesis eversion technique (55 patients) and a conventional technique (53 patients).
  • Data collected included cardiopulmonary bypass time, aortic cross-clamping time, operation duration, blood loss, re-exploration rates, blood transfusion, ICU stay, and hospitalization costs.

Main Results:

  • The modified technique group had shorter durations for cardiopulmonary bypass, aortic cross-clamping, and total operation.
  • Perioperative blood loss and re-exploration for bleeding were significantly lower in the modified group.
  • The modified group experienced shorter ICU and hospital stays, with lower total hospitalization costs.

Conclusions:

  • The modified prosthesis eversion technique is an effective alternative for proximal anastomosis in ascending aorta replacement.
  • It offers advantages such as reduced blood loss, shorter operation times, and fewer postoperative complications.
  • This technique represents an improvement over the conventional method.
