6-8) Similar to hepatic artery
stenosis, portal vein stenosis occurs at the anastomotic site and can be identified by a focal area of luminal narrowing (< 2.
The 5 Fr catheter was then successfully advanced into the proper hepatic artery
using the balloon anchor technique and the recurrent HCC was treated by means of selective B-TACE.

The following is the case of a patient taken to retransplant surgery three times due to hepatic artery
thrombosis (initial indication was alcoholic cirrhosis and hepatocarcinoma), with residual HA thrombosis after the third transplant surgery.
Graft hepatic artery
with right hepatic artery
(RHA) and duct-to-duct anastomosis were performed.
The rate of hepatic artery
stenosis (HAS) is between 11% and 19%  and stenosis usually occurs within 3 months post transplant.
This is because the blood supply to the liver is already compromised due to PV thrombosis, and embolization of the hepatic artery
may result in hepatic infarction and/or acute hepatic failure, especially in patients with limited hepatic reserve.
10,11) Liver transplantation has been used for treatment of a small number of patients who develop acute or chronic liver failure due to the catastrophic complication of IBDI, such as hepatic necrosis in the presence of concomitant portal vein and/ or hepatic artery
damage or secondary biliary cirrhosis as a consequence of inappropriate management of transected bile duct with too lengthy stent placement or inadequate treatment of stenotic hepaticojejunostomy.
Color Doppler sonography of the common and proper hepatic artery
and the portal vein was performed to evaluate the possibility of the luminal invasion of a cholangiocarcinoma or adenocarcinoma of the pancreas as differential diagnoses, which revealed reduced blood flow of the common hepatic artery
and proper hepatic artery
without any intraluminal lesion.
In contrast to healthy liver cells, which receive blood from both the hepatic artery
and portal vein, HCC cells receive blood mainly from the hepatic artery
via a vascular network formed in the tumor tissue.
Trace the right gastric artery to the proper hepatic artery
; expose the proper hepatic artery
and its branches to the porta hepatis.
