Effects of hepatic artery type and number on bile complications in right lobe living donor liver transplant recipients: single center experience without hepatic artery thrombosis

Abstract

Purpose: Hepatic artery provides blood supply to the biliary tract of the graft, one of the causes of the biliary complications that may occur in the post-transplant period may be the problems of the recipient's hepatic artery. We examined the effect of post-transplant biliary complications according to the type and number of recipient hepatic artery. Materials and Methods: One hundred eighty five patients older than 18 years of age who underwent right lobe LDLT for end-stage liver cirrhosis were included in the study. The recipient's right hepatic artery (RHA), left hepatic artery (LHA), propria hepatic artery (PHA) and common hepatic artery (CHA), which were anastomosed to the graft artery and double hepatic artery anastomoses formed of the right and left hepatic arteries, were examined. Biliary complications were analyzed statistically in terms of single or double artery anastomosis and anastomoses with the right or the other hepatic arteries. Results: There was no statistically significant difference between single and dual artery anastomoses in terms of bile duct stricture or leakage (p=0.767). No statistically significant difference was observed between RHA, LHA, PHA, CHA, and between single and dual arteries in the evaluation of artery selection between those with and without biliary tract complications (p=0.445) Conclusion: Hepatic artery type selection and number of the recipient does not change the biliary tract complication.

Sağ lob canlı verici karaciğer nakli alıcılarında hepatik arter çeşidi ve sayısının safra komplikasyonları üzerine etkileri: hepatik arter trombozu olmaksızın tek merkez deneyimi

Abstract

Amaç: Hepatik arter, grefte ait safra yollarının kanlanmasını sağlar. Nakil sonrası dönemde oluşabilecek safra komplikasyonlarının nedenlerinden biri de alıcının hepatik arterindeki sorunlar olabilir. Alıcı hepatik arterin tipine ve sayısına göre nakil sonrası safra komplikasyonlarının etkisini inceledik. Gereç ve Yöntem: Çalışmaya, son dönem karaciğer sirozu nedeniyle sağ lob LDLT uygulanan 18 yaş üstü 185 hasta dahil edildi. Alıcının greft arterine anastomoz yapılan sağ hepatik arter (RHA), sol hepatik arter (LHA), propria hepatik arter (PHA) ve ana hepatik arter (CHA) ve sağ ve sol hepatik arterlerden oluşan çift hepatik arter anastomozları incelendi. Biliyer komplikasyonlar tek veya çift arter anastomozu ve sağ veya diğer hepatik arterlerle anastomoz yapılması açısından istatistiksel olarak analiz edildi. Bulgular: Tek ve çift arter anastomozları arasında safra kanalı darlığı veya sızıntısı açısından istatistiksel olarak anlamlı fark yoktu (p=0,767). Safra yolu komplikasyonu olan ve olmayanlar arasında arter seçiminin değerlendirilmesinde RHA, LHA, PHA, CHA ile tek ve çift arterler arasında istatistiksel olarak anlamlı fark gözlenmedi (p=0,445). Sonuç: Alıcılarda anastomozda kullanılan hepatik arter tipi ve sayısı sayısı safra yolu komplikasyon oranını değiştirmemektedir.
