The late post-operative patency rate of aorto-coronary venous grafts
The Journal of Cardiovascular Surgery
|January 1, 1980
Abstract:
Long-term aorto-coronary venous graft patency has been examined in a consecutive series of 47 patients (average: 1.6 graft per patient) after a mean follow-up period of 5 years and 9 months (44-108 months) post surgery. Overall patency rate was 71% (52/73 grafts), with the best results for LAD grafts 85% (27/32). Seventy-seven percent of the patients experienced lasting relief from angina. Significant improvement of LV ejection fraction was observed in cases with patent grafts.

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
