Vasculature hepatic artery

Loukas M, Fergurson A, Louis RG Jr, Colborn GL (2006) Multiple variations of the hepatobiliary vasculature including double cystic arteries, accessory left hepatic artery and hepatosplenic trunk a case report. Surg Radiol Anat 28 525-528... 

Preoperative imaging of the liver transplant recipient should depict in detail the relevant vasculature anatomy, and reveal the presence of variants that are important for surgical planning (Table 4.2.4 Erbay et al. 2003). The most common arterial variants that are relevant in potential liver transplant recipients include replaced or accessory hepatic arteries from the superior mesenteric artery. A replaced... 

The transplant vasculature is examined with both gray-scale and Doppler US. The most common vascular complications post liver transplantations are abnormalities involving the hepatic artery, with an incidence ranging between 4% and 25%. Risk factors for arterial complications include anastomosis to the abdominal aorta, donor arterial variants requiring multiple anastomoses, and pediatric age recipient. 

Evaluation of the hepatic vasculature is essential before tumor resection. MRI or CT can show vascular involvement even without contrast enhancement. Other modalities such as 3D MRA have been used for this purpose, with the advantage that the images can be studied in both the arterial and venous phases (Haliloglu et al. 2000).
