Insights
This study introduces a novel cardioplegic solution injection technique for coronary artery endarterectomy. This method facilitates revascularization in patients with diffuse atherosclerosis, offering a viable surgical option for complex cases.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Vascular Endarterectomy Techniques
Background:
- Diffuse atherosclerotic changes in coronary arteries pose challenges for traditional revascularization.
- Existing surgical techniques may have limitations in addressing widespread disease.
- The need for improved methods for coronary artery endarterectomy is evident.
Purpose of the Study:
- To present a novel technique for coronary artery endarterectomy using cardioplegic solution injection.
- To evaluate the efficacy and safety of this technique in patients with diffuse coronary artery disease.
- To assess the potential for wider application of surgical treatment in complex cases.
Main Methods:
- A simple and gentle technique involving injection of cardioplegic solution into the plane of endarterial dissection.
- Combined manual endarterectomy to facilitate separation of the diseased core.
- Application in 116 coronary revascularization procedures between 1991 and 1996.
Main Results:
- The technique enabled revascularization in patients with diffuse atherosclerotic changes.
- Endarterectomy was performed on the right coronary artery in 82 patients.
- Mortality rate was 4.88%, and perioperative myocardial infarction rate was 4.88% in the right coronary artery group.
Conclusions:
- The presented cardioplegic solution injection technique is effective for coronary artery endarterectomy.
- This method aids in treating diffuse coronary artery disease, improving surgical options.
- The technique shows promise for broader application in challenging revascularization scenarios.
Abstract:
We present our technique of performing endarterectomy of coronary arteries by means of injecting cardioplegic solution into the plane of dissection of the endarterium. This simple and gentle technique in combination with manual endarterectomy helps in separation of the core far into the periphery of the diseased vessel and thus helps to perform revascularization in patients with diffuse atherosclerotic changes. During the last 6 years (1991-1996) endarterectomy in coronary revascularization was used in 116 cases (it was 5.7 % (116/2031) of all myocardial revascularization procedures). On right coronary artery endarterectomy was used in 82 patients. Mortality rate in our group of patients was 4.88 % (4/82) and perioperative myocardial infarction developed in 4.88 % (4/82). According to our own experience with this technique of endarterectomy on right coronary artery we are convinced that in desperate patients with diffuse coronary artery disease our method can bring better and wider application of surgical treatment.
