[Internal thoracic artery in coronary surgery]
Insights
The internal thoracic artery is effective for coronary artery bypass grafting, showing higher patency rates for shunts compared to arterial-coronary shunts (ACSh). This surgical approach offers significant long-term benefits for ischemic heart disease patients.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery
- Vascular Surgery
Context:
- Ischemic heart disease management
- Coronary artery bypass grafting (CABG) techniques
- Historical use of internal thoracic artery (ITA) in cardiac surgery since 1964
Purpose:
- To evaluate the long-term effectiveness and patency rates of internal thoracic artery (ITA) for mammary-coronary shunts.
- To compare the outcomes of ITA mammary-coronary shunts with arterial-coronary shunts (ACSh).
Summary:
- A retrospective analysis of 257 operations involving mammary-coronary shunts and anastomosis (V. I. Kolesov technique) was conducted.
- Long-term follow-up included angiographic examinations in 109 patients up to 12 years post-surgery.
- Internal thoracic artery (ITA) shunts demonstrated a superior patency rate of 83.5% compared to arterial-coronary shunts (ACSh) at approximately 63%.
Impact:
- Highlights the significant long-term efficacy of using the internal thoracic artery for coronary artery bypass.
- Provides evidence supporting ITA as a preferred conduit for improving coronary blood flow in ischemic heart disease.
- Contributes to the understanding of surgical outcomes in myocardial revascularization.
Abstract:
The authors emphasize advantages of using the internal thoracic artery for mammary-coronary shunts in patients with ischemic heart disease. 257 operations have been performed in the clinic since 1964. Among them there were operations of mammary-coronary anastomosis (after V. I. Kolesov) and mammary-coronary shunts. Long-term results were followed-up which evidence high effectiveness of operative treatment. In 109 patients control angiographic examinations were fulfilled at different terms (up to 12 years). Patency of mammary-coronary shunts was 83.5% as compared with ACSh where it was about 63%.
