[Use of the internal mammary artery in myocardial revascularization]

|January 1, 1977
Insights
The internal mammary artery is rarely narrowed or blocked, making it suitable for heart bypass surgery. Surgeons found these vessels, even small ones, easy to stitch during cadaver dissections.
Area of Science:
- Anatomy
- Vascular Surgery
- Cardiology
Context:
- Internal mammary artery (IMA) anatomy is crucial for myocardial revascularization.
- Previous studies have not extensively documented IMA changes in large cadaver populations.
- Understanding IMA patency is vital for the success of coronary artery bypass grafting.
Purpose:
- To investigate the prevalence of sclerosis, stenosis, and occlusion in the internal mammary artery.
- To assess the suitability of the internal mammary artery for coronary artery bypass grafting procedures.
Summary:
- A study of 3409 cadavers revealed that sclerosis, stenosis, and occlusion of the internal mammary artery are exceptionally rare.
- The internal mammary artery, with diameters of 1.5 to 2.5 mm, proved easy to suture in cadaveric anastomoses.
- These findings support the internal mammary artery's utility in myocardial revascularization via mammary-coronary anastomosis.
Impact:
- Provides anatomical evidence supporting the internal mammary artery's reliability for coronary artery bypass surgery.
- Highlights the low risk of vessel disease in the IMA, enhancing its role in cardiac revascularization.
- Offers practical insights for surgeons performing mammary-coronary anastomosis, confirming vessel manageability.
Abstract:
A total of 3409 cadavers was studied for changes of the internal mammary artery; sclerosis stenosis and occlusion of the vessel were quite exceptional. This fact is believed to be of importance from the aspect of myocardial revascularization by mammary-coronary anastomosis. Anastomoses were performed on cadavers; the vessels 1.5 to 2.5 mm in diameter were easy to suture.
