Aim. Little has been reported on the effect of continuous ambulatory peritoneal dialysis (CAPD) as the primary dialysis treatment after open heart surgery in dialysis-dependent adults. The purpose of this study was to evaluate the clinical results of aortic valve replacement for dialysis patients and to comfirm the validity of temporary CAPD.
Methods. In a retrospective study, we reviewed the surgical results of 41 dialysis patients (mean age 65.6±7.6 years, 31 men) undergoing aortic valve replacement: CAPD was the temporary dialysis treatment during the acute postoperative period in 34 of these patients (group C). Mean follow-up time was 4.0±3.7 years.
Results. The overall hospital mortality was 7.3% (3 patients, 1 in group C). CAPD was performed for 9.2±6.1 days. There were no cases of stroke or mesenteric ischemia in group C. Only 2 patients in group C (5.9%) required glucose-insulin therapy. Eight episodes of suspicion of CAPD peritonitis were encountered; however, all were aseptic and were successfully treated with irrigation and antibiotic therapy. The overall 3-, 5-, and 10-year Kaplan-Meier survival rates were 72.3±7.6%, 57.1±9.0%, and 38.9±1 1.5%, respectively.
Conclusion. Our study demonstrates good early and long-term clinical results of aortic valve replacement in dialysis patients. CAPD is a safe and valid temporary dialysis method during the acute postoperative period after aortic valve replacement in dialysis patients.
