Thoracoscopic harvesting of the internal mammary artery (IMA) offers a safer alternative to traditional methods for minimally invasive cardiac surgery. This technique reduces surgical trauma and avoids complications associated with open procedures.

Area of Science:

  • Cardiovascular Surgery
  • Minimally Invasive Techniques
  • Surgical Anatomy

Background:

  • Minimally invasive cardiac surgery, including MIDCAB and totally endoscopic CABG, aims to reduce surgical trauma.
  • Traditional internal mammary artery (IMA) harvesting via limited thoracotomy or mediastotomy presents challenges.
  • These challenges include difficulty in complete dissection, potential for costal resection, chest wall retraction, kinking, and coronary steal syndrome.

Purpose of the Study:

  • To describe and evaluate the safety and reproducibility of thoracoscopic IMA harvesting.
  • To present a prerequisite technique for totally endoscopic and/or robotic coronary artery bypass grafting (CABG).

Main Methods:

  • Thoracoscopic dissection of the IMA from the subclavian artery to the sixth intercostal space.

  • Sectioning of all collateral branches originating from the IMA.
  • Application of the technique regularly since 1995.

    • Main Results:

    • Thoracoscopic IMA harvesting avoids the hazards of open procedures, such as traumatic retraction.
    • The technique allows for complete graft dissection without compromising the vessel.
    • The method has proven safe and reproducible after adequate training.

    Conclusions:

    • Thoracoscopic IMA takedown is a safe and reproducible technique for minimally invasive cardiac surgery.
    • It serves as an essential prerequisite for achieving totally endoscopic or robotic CABG.
    • This approach enhances surgical efficacy while minimizing patient trauma.
