Abstract

Amaç: Tünelli diyaliz kateterleri genellikle primer diyaliz erişim yolu olarak değil kalıcı bir diyaliz erişim yoluna erişene kadar köprü tedavisi olarak uygulanmaktadır. Fakat ihtiyaç duyulması halinde uzun dönem kullanımının uygun olabileceği belirtilmiştir. Çalışmamızda geniş bir hasta grubunda tünelli diyaliz kateterlerin uzun dönem açık kalım oranlarını ve kateter ilişkili hastalıkların sıklığını ortaya koymayı amaçladık.
Gereç ve Yöntem: 2017-2022 yılları arasında merkezimize tünelli diyaliz kateteri takılması işlemi için başvuran hastaların kateter açık kalma süreleri retrospektif olarak incelendi. Hastaların kateter disfonksiyonu nedeniyle merkezimize tekrarlayan başvuruları arasındaki süre, disfonksiyonun nedeni ve açıklığı sağlamak için uygulanan prosedür not edildi. Kateterlerin açıklık oranlarını hesaplamak için Kaplan Meier sağkalım analizi kullanıldı.
Bulgular: Merkezimize tünelli diyaliz kateteri takılması veya işlev bozukluğu nedeniyle başvuran 464 hastaya 1010 işlem yapıldı. Kısa süreli takip veya veri eksikliği nedeniyle 309 hasta çalışma dışı bırakıldı. Geri kalan155 hasta, 211 kateter bölgesi çalışmaya dahil edildi ve 467 girişimsel işlem verileri analiz edildi. Tünelli diyaliz kateterlerinin ortalama primer açık kalma süresi 10,50 ± 10,25 ay, sekonder açık kalma süresi ise 18,00 ± 13,77 ay idi. Tüm tünelli diyaliz kateterlerinin 6, 12 ve 24 aylık açık kalım oranları sırasıyla %91,1, %83,9 ve %77,9 olarak tespit edildi.
Sonuç: Arteriyovenöz yol için ilk tercih olmaması gereken kalıcı diyaliz kateterleri, eşlik eden komorbiditelere sahip olmakla birlikte, diğer giriş yollarının uygun olmadığı durumlarda kullanılabilecek açıklık oranları tatmin edici olan bir yöntemdir.

Long-term outcome of permanent hemodialysis catheters: a single center experience

Abstract

Aim: Tunneled dialysis catheters are generally not used as a primary dialysis access but as bridging therapy until a permanent dialysis access is available. However, it has been stated that long-term use may be appropriate if needed. In our study, we aimed to reveal the long-term patency rates of tunneled dialysis catheters and the frequency of catheter-related diseases in a large patient group.
Material and Method: Patients who referred to our center for tunneled dialysis catheter insertion procedure between 2017 and 2022 were retrospectively analyzed with respect of catheter patency durations. The duration between the patients’ repetitive admissions to our center due to catheter dysfunction, the cause of the dysfunction and the procedure applied to achieve the patency were noted. Kaplan- Meier survival analysis was used to calculate patency rates of catheters.
Results: 1010 procedures were performed on 464 patients who applied to our center for tunneled dialysis catheter creation or dysfunction. 309 patients were excluded from the study due to short-term follow-up or lack of data. Of the remaining 155 patients with 211 catheter sites included to the study and 467 interventional procedures data analyzed. The mean primary patency duration of the tunneled dialysis catheters was 10.50±10.25 months and the secondary patency duration was 18.00±13.77 months. The 6, 12, and 24-month patency rates of the overall tunneled dialysis catheters were 91.1 %, 83.9 % and 77.9% respectively
Conclusion: Although permanent dialysis catheters, which should not be the first choice for arteriovenous access, have associated comorbidities, they are a method with satisfactory patency rates when other access types are not suitable.
