[Experience of coronary artery bypass grafting with internal thoracic artery]
Insights
Internal thoracic artery grafts show superior patency compared to saphenous vein grafts in coronary artery bypass grafting (CABG). This study highlights improved graft survival for CABG patients.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Coronary artery bypass grafting (CABG) is a critical intervention for coronary artery disease.
- Graft selection significantly impacts long-term outcomes in CABG procedures.
- Internal thoracic arteries (ITAs) and saphenous veins (SVs) are commonly used conduits.
Purpose of the Study:
- To evaluate the early patency rates of internal thoracic artery grafts versus saphenous vein grafts.
- To assess the overall efficacy and safety of CABG using these conduits.
Main Methods:
- A cohort of 29 patients underwent CABG between March 1990 and May 1991.
- The mean number of grafts per patient was 2.7.
- Internal thoracic arteries were used in 96.6% of cases, with postoperative coronary angiography performed at one month.
Main Results:
- Overall graft patency was 96.7% (58/60 grafts).
- Internal thoracic artery grafts demonstrated 100% (29/29) early patency.
- Saphenous vein grafts showed 93.5% (29/31) early patency, with ITA grafts outperforming SV grafts.
Conclusions:
- Internal thoracic artery grafts exhibit superior early patency rates compared to saphenous vein grafts in CABG.
- The findings support the preferential use of ITAs for improved long-term graft survival in CABG patients.
- CABG with ITAs demonstrates excellent early results with low perioperative mortality (3.4%).
Abstract:
Between March 1990 and May 1991, twenty-nine patients underwent coronary artery bypass grafting. The mean number of grafts was 2.7 +/- 0.9 grafts per patient. 28 patients (96.6% of all cases) underwent CABG with the internal thoracic arteries. The perioperative mortality was 3.4% (1/29 cases). The postoperative coronary angiography at one month revealed that the early patency of total grafts, of internal thoracic artery grafts and of saphenous vein grafts were 96.7% (58/60 grafts), 100% (29/29 grafts), 93.5% (29/31 grafts) respectively. The early patency of internal thoracic artery graft was better than of saphenous vein graft.
