Vineberg's procedure modified technique: flow analysis, immediate postoperative results and angiographic evaluation

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Vascular Biology

Background:

• The Vineberg procedure is a surgical technique for myocardial revascularization.
• Evaluating modifications to the Vineberg procedure is crucial for improving patient outcomes.
• Assessing graft flow and clinical results provides insight into surgical efficacy.

Purpose of the Study:

• To evaluate angiographic results of a modified Vineberg procedure.
• To assess morbidity and mortality in the immediate postoperative period.
• To analyze the flow of grafted left internal thoracic artery (LITA) at rest and under stress.

Main Methods:

• Eight patients underwent internal thoracic artery (ITA) implantation into the left ventricle (LV) muscle.
• Postoperative evaluation included angiography and Doppler assessment at 6 months.
• Comparison was made with a control group (n=20) with direct LITA revascularization of the anterior interventricular artery (AIV).

Main Results:

• 100% graft patency was observed in all patients.
• No deaths or immediate postoperative complications occurred.
• The modified Vineberg group showed 55% of the total flow compared to the control group, with increased flow under stress.

Conclusions:

• The modified Vineberg's technique is a viable option for patients ineligible for direct revascularization.
• This approach demonstrates low morbidity and mortality rates.
• It ensures significant blood flow from the left internal thoracic artery (LITA) graft, both at rest and during stress.
