Insights
Off-pump coronary artery bypass grafting is a safe and effective option for patients with dialysis-dependent renal failure, showing good clinical results and improved patient outcomes. This surgical approach offers a viable solution for this high-risk population.
Area of Science:
- Cardiovascular Surgery
- Nephrology
- Cardiac Surgery
Background:
- Patients with end-stage renal disease requiring dialysis often have coexisting coronary artery disease.
- These patients are considered high-risk for traditional coronary artery bypass grafting due to comorbidities.
Purpose of the Study:
- To evaluate the safety and efficacy of off-pump coronary artery bypass grafting (OPCABG) in patients with dialysis-dependent renal failure.
- To assess perioperative variables and postoperative outcomes in this specific patient cohort.
Main Methods:
- Retrospective review of 10 patients with dialysis-dependent renal failure who underwent OPCABG between March 2001 and May 2005.
- Coronary artery bypass grafting performed on a beating heart without cardiopulmonary bypass.
- Evaluation of perioperative and postoperative outcomes, including mortality, ischemic events, and functional status.
Main Results:
- No perioperative or postoperative deaths or ischemic cardiac events were observed in the study group.
- Significant improvement in anginal symptoms and functional status postoperatively.
- Low complication rates, with no need for revision due to hemorrhage; short intensive care unit and hospital stays.
Conclusions:
- Off-pump coronary artery bypass grafting can be performed with favorable clinical outcomes in patients with dialysis-dependent renal failure.
- OPCABG is a suitable and effective revascularization strategy for this high-risk patient population.
Objective:
Patients with dialysis-dependent renal disease frequently present with coronary artery disease. These patients are considered to be at high risk for coronary artery bypass grafting. Therefore, off-pump coronary artery surgery may become a good option for these patients. Off-pump coronary artery bypass surgery in patients with dialysis-dependent renal failure was retrospectively reviewed in this study.
Methods:
From March 2001 through May 2005, we performed off-pump coronary bypass grafting in 10 patients with dialysis-dependent renal failure. Coronary artery bypass grafting was performed on beating heart in all of the patients. The patients were evaluated for perioperative variables and postoperative outcomes.
Results:
Mean age was 58.7+/-8.9 years with a range between 45 to 76 years. Eight of the patients were male and two were female. No perioperative and postoperative deaths or ischemic cardiac events were observed. Anginal symptoms of the patients were relieved during the postoperative period. Functional status of the patients was improved postoperatively. None of the patients needed revision due to hemorrhage. Mean distal anastomosis number was 1.8+/-0.6. Mean intensive care unit stay was 1.8+/-0.8 days and hospital stay was 5.3+/-0.9 days.
Conclusion:
Off-pump coronary artery bypass grafting can be performed with good clinical results. We believe that off-pump coronary revascularization is a good option in patients with dialysis-dependent renal failure.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
