Implication

Supports off-pump CABG feasibility in select cases; hypothesis-generating and requires randomized confirmation before practice change.

Key Points

To evaluate the feasibility, safety, and graft patency of coronary artery saphenous vein bypass revascularization performed without cardiopulmonary bypass.
Retrospective clinical series of 160 patients (selected from 597 total bypass cases, 26.8%) who underwent off-pump coronary revascularization using saphenous vein grafts.
Surgical anastomoses were constructed with interruption of coronary flow without perfusion devices distally and tangential aortic clamping proximally, most frequently targeting the anterior descending and distal right coronary arteries.
Postoperative evaluation included continuous monitoring via daily electrocardiograms, CK-MB enzyme levels, and follow-up angiographic hemodynamic studies in 41 patients.
In-hospital mortality was 3.1% (5/160), and perioperative myocardial infarction occurred in 2.5% of patients (4/160).
Angiographic restudy in 41 patients evaluated 62 bypass grafts, demonstrating an overall graft patency rate of 83.9%.
Eliminating extracorporeal circulation avoided donor blood usage and lowered medical costs through shortened hospital stays.

Structured PICO

Is coronary artery saphenous vein bypass revascularization without cardiopulmonary bypass safe and effective in patients requiring bypass surgery?

Population

160 patients undergoing coronary artery saphenous vein bypass revascularization (selected from a total of 597 patients who underwent bypass surgery during the period)

Intervention

Coronary artery saphenous vein bypass revascularization without cardiopulmonary bypass (off-pump)

Outcome

Hospital mortalityhard clinical

Coronary artery bypass grafting without cardiopulmonary bypass is feasible and safe, achieving good graft patency while avoiding the need for extracorporeal circulation.
