Insights

A novel technique for harvesting the internal thoracic artery pedicle for minimally invasive bypass surgery is safe and effective. This method shows high graft patency rates and excellent patient outcomes, offering an inexpensive surgical option.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Minimally Invasive Surgery

Background:

  • Coronary artery bypass grafting (CABG) is a standard treatment for coronary artery disease.
  • Minimally invasive techniques aim to reduce surgical trauma and improve recovery.
  • Harvesting the internal thoracic artery (ITA) pedicle is crucial for successful CABG.

Purpose of the Study:

  • To describe a simple, safe, and cost-effective method for harvesting the ITA pedicle.
  • To evaluate the early and long-term outcomes of this harvesting technique in minimally invasive CABG.

Main Methods:

  • A simple technique using a small scapular retractor for ITA pedicle harvesting was developed.
  • The technique was applied in 39 patients undergoing minimally invasive CABG.
  • Postoperative angiography assessed graft patency; clinical follow-up monitored outcomes.

Main Results:

  • The ITA pedicle harvesting technique was successfully used in 39 patients.
  • Early postoperative angiography showed a 96% graft patency rate.
  • Long-term follow-up (mean 9.6 months) in 63% of patients demonstrated a 95.4% cumulative patency rate with no evidence of graft 'steal'.
  • No perioperative deaths or myocardial infarctions occurred; only 2 patients experienced recurrent angina.

Conclusions:

  • This simple ITA pedicle harvesting technique is safe and effective for minimally invasive CABG.
  • The method offers high graft patency and favorable clinical outcomes.
  • It presents an inexpensive and viable surgical option for selected patients.
