Limitations of using arterial conduit for myocardial revascularization in patients with combined coronary and other arterial lesions.

To explore the limitations of using arterial conduit for myocardial revascularization in patients with combined coronary and other arterial lesions, we evaluated 195 patients with combined lesions undergoing CABG, either alone or in combination with peripheral vascular reconstruction between October 1987 to October 1990. Doppler flow and spectral analysis revealed that 14 patients (7.1%) had atherosclerotic lesions of the subclavian artery, in whom ipsilateral internal mammary artery pedicle graft was contraindicated for myocardial revascularization.

Antegrade and retrograde cardioplegia with different reperfusion techniques in patients with multiple coronary artery lesions.

To evaluate the effectiveness of retrograde cardioplegia and reperfusion, a total of 266 patients undergoing coronary bypass surgery between Nov 1987 to Dec 1989 were divided into three groups depending on the method of cardioplegic fluid delivery and reperfusion. In group I (80 patients) antegrade cardioplegia and reperfusion was used. In group II (98 patients) antegrade and retrograde cardioplegia and antegrade reperfusion was used while in group III antegrade and retrograde cardioplegia and retrograde reperfusion was used.

[Risk factors and methods of prevention of complications in digestive organs after myocardial revascularization in patients with generalized atherosclerosis].

The clinico-hemodynamic and angiographic findings in 66 patients with ischemic heart disease were analysed to identify the risk factors of complications in the digestive system and to determine the methods for their prevention after myocardial revascularization. It was found that complications in the gastrointestinal tract develop after extracorporeal circulation more often in patients with lesions of the visceral branches of the abdominal aorta than in those without them. With purposeful preventive therapy and observance of definite precautions before, during, and after the operation, the incidence of complications in abdominal organs and the organs of the retroperitoneal space reduced to one fourth while the nature of these complications was less aggressive.
