Objectives There is an increased calcium phosphate product level causing the formation of calcification in the arterial wall and thus decreased quality of fistula in patients with chronic renal failure. The purpose of our study is to verify the relationship between arteriovenous fistula re-operation and high calcium phosphate product level. Methods Seventy-nine consecutive patients with chronic renal failure between April 2016 and February 2018 were included in the study. Patients having calcium phosphate product level ≥50 mg2/dl2 were defined as group 1, whereas those having <50 mg2/dl2 were defined as group 2. Primary outcome of interest was the need for re-operation during the follow-up and to determine the risk factors for re-operation. To determine independent predictors for re-operation, multivariate logistic regression model was used. Results The rates of redo and tredo operation were significantly higher in group 1 compared to group 2 ( p = 0.01 and 0.04). In multivariate analysis, phosphate (OR: 1.84, 95% CI: 1.00–3.40, p = 0.05) and triglyceride (OR: 1.01, 95% CI: 1.00–1.02, p = 0.04) levels for redo operation and calcium phosphate product level (OR: 1.11, 95% CI: 1.01–1.22, p = 0.03) for tredo operation were found to be independent predictors. Conclusions High calcium phosphate product level leads to increased risk of arteriovenous fistula re-operation by causing arterial stiffness in this patient group. Additionally, these re-operations place additional burden on morbidity and cost efficacy. Thus, we recommend keeping the calcium phosphate product level at the optimal level in these patients to avoid both the risk of arteriovenous fistula re-operation and the other cardiovascular problems.
Aort kapak replasmanı (AVR) sonrası sağkalımı etkileyen çok çeşitli faktörler belirlenmişse de operasyon sonrası yaşam kalitesini etkileyen faktörler hakkında bilgimiz fazla değildir. Bunun yanı sıra yaşam kalitesini kantitatif olarak değerlendirmek oldukça zordur. Biz bu çalışmamızda AVR yapılan hastalarda, aort patolojilerinin farklılığının postoperatif erken dönemde yaşam kalitesi üzerine etkisinin olup olmadığını araştırdık.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
