The Unusual Localization of Right Hepatic Artery Multiple Anatomic Variants in Celiac Axis

Abstract

The extrahepatic vascular and biliary anatomy of Calot\'s triangle is well known to be highly variable and this provides a surgical challenge. The liver has a dual blood supply consisting of the portal vein and the hepatic artery. The hepatic artery which delivers 25% of the blood supply, arises from the celiac trunk. The celiac trunk gives off the left gastric, splenic and common hepatic arteries. The common hepatic artery then divides into gastroduodenal artery and hepatic artery proper which diverts in right and left hepatic arteries. The systic artery usually originates from the right hepatic artery. The “classic” arterial anatomy is present in approximately 75% of cases. The remaining 25% of the cases have many anatomical variants. Here in we present a patient with multiple anatomic variants in celiac trunk which were determined incidentally during laparoscopic cholecystectomy. Being aware of the arterial variations in the liver is really important in surgical procedures in order to avoid bleeding and ischemia.

The Unusual Localization of Right Hepatic Artery Multiple Anatomic Variants in Celiac Axis

Abstract

Ekstrahepatik vasküler ve Calot’s üçgeninin biliyer anatomisi oldukça değişken olduğu bilinmektedir ve bu cerrahi bir endişe oluşturur. Karaciğer portal ven ve hepatik arterin oluşturduğu ikili bir kan kaynağına sahiptir. Çölyak trunkusdan kaynak alan hepatik arter kan akımının % 25’ini sağlar. Çölyak trunkus, sol gastrik arter, splenik arter ve ortak hepatik arter dallarını verir. Daha sonra ortak hepatik arter; gastroduodenal arter ve hepatik arteri verir, hepatik arter de sağ ve sol hepatik dallara ayrılır. Sistik arter genellikle sağ hepatik arterden kaynaklanmaktadır. "Klasik" arteriyel anatomi vakaların yaklaşık% 75'inde mevcuttur. Olguların% 25'inde pek çok anatomik varyantlar vardır. Biz laparoskopik kolesistektomi sırasında tesadüfen tespit edilen Çölyak trunkusunda birden anatomik varyantları olan bir hastayı sunduk. Cerrahi işlemler sırasında kanama ve iskemiyi önlemek için karaciğer içinde arteriyel varyasyonları bilmek çok önemlidir
