Risk Factors Associated with Dysfunction of Permanent Tunneled Cuffed Hemodialysis Catheters; Single Center Experience

Risk Factors Associated with Dysfunction of Permanent Tunneled Cuffed Hemodialysis Catheters; Single Center Experience Introduction: tunneled cuffed catheters are frequently preferred for hemodialysis in patients chronic renal failure (CRF), but the factors associated dysfunction these not well known. Our goal is to investigate risk factors. Materials and Methods: All cases a diagnosis CRF permanent catheter inserted into central vein first time our radiology clinic between 2014 2019 who developed were included study. Demographic clinical data obtained from file records. The relationship causes presence diabetes hypertension was investigated. Results: Of total 123 cases, 78 (63.4%) male, 45 (36.6%) female, median age 55 (28-78). Twenty-nine (23.6%) had thrombosis, 72 (58.5%) venous stenosis 22 (17.9%) due fibrin sheath. groups compared each other terms age, gender, duration operation catheter, etiology, comorbid diseases, where placed use anticoagulants. most important cause early period thrombosis (p = 0.003). When examined, common hypertension, as concomitant disease without etiology CRF, 0.05). Conclusion: low-dose anticoagulants plays protective role against thrombosis. contraindications, especially diabetic patients, may reduce dysfunction.
