Area of Science:

  • Cardiothoracic Surgery
  • Vascular Surgery
  • Surgical Techniques

Background:

  • Elephant trunk procedures are critical for complex aortic arch pathologies.
  • Managing massively enlarged aortas presents significant surgical challenges.
  • Existing retrieval techniques may have limitations in specific anatomical scenarios.

Purpose of the Study:

  • To illustrate the "Finger-Thumb Technique" for elephant trunk retrieval.
  • To present a video demonstration of this specialized surgical maneuver.
  • To highlight the technique's utility in challenging aortic dissections.

Main Methods:

  • The "Finger-Thumb Technique" for elephant trunk retrieval is demonstrated via video.
  • The technique involves specific manipulations for securing the graft in the ascending aorta.

  • Application is shown in the context of second-stage elephant trunk procedures.

    • Main Results:

    • The Finger-Thumb Technique provides a viable method for elephant trunk retrieval.
    • The technique is particularly useful when direct proximal aortic manipulation is difficult.
    • Successful application requires significant surgical experience and expertise.

    Conclusions:

    • The Finger-Thumb Technique is a valuable addition to the cardiothoracic surgeon's armamentarium.
    • It offers a safe and effective option for elephant trunk retrieval in select aortic cases.
    • Surgeons should consider this technique for managing enlarged aortas where other methods are less suitable.
