The high incidence of hepato-biliary vascular anatomy variations necessitates its evaluation prior to performing liver transplantation, hepatobiliary, pancreatic, gastric and oesophageal surgeries. We report a unique case of persistence of embryonic arteries of the liver, wherein, the liver was supplied by five vessels. In addition to the usual right and left hepatic arteries from the hepatic artery proper, the liver received two accessory right hepatic arteries, one from the gastroduodenal artery, while another arising from superior mesenteric artery and an accessory left hepatic artery, from the left gastric artery. The origin of gastroduodenal artery was found to be unusually high and its abnormal anterior course over the common bile duct further added complexity to the hepatobiliary anatomy. The presence of these aberrant and accessory arteries predisposes to inadvertent injury leading to patient morbidity and sometimes mortality.

Artery Resection

Resection of biliary tract malignancies may require resection of the hepatic vasculature. While immediate revascularization of the liver is necessary, reconstruction is difficult when the original vessels are unavailable. We document a case in which a segment of the common hepatic artery was excised during tumor resection and the remaining proximal vessel displayed intima dissection. A greater saphenous vein was placed as a bridge between the remaining left hepatic artery and gastroduodenal artery for successful revascularization.

Abstract Hepatic artery aneurysms are responsible for 12% to 20% of all visceral arterial aneurysms. Because most patients are asymptomatic, this disease is generally diagnosed incidentally during radiologic examination. Aneurysm rupture develops in 14% to 80% of cases, depending on the aneurysmatic segment's diameter and location, as well as other etiologic factors. Mortality rates associated with rupture range between 20% and 70%. Thus, early diagnosis and timely initiation of medical interventions are critical to improve survival rates. Here, we present a male patient, age 69 years, with a hepatic artery aneurysm that was detected incidentally. The 3-cm aneurysm was detected on contrast-enhanced computed tomography and extended from the common hepatic artery to the hepatic trifurcation. A laparotomy was performed using a right subcostal incision. After dissection of the hepatoduodenal ligament, the common, right, and left hepatic arteries, as well as the gastroduodenal artery, were suspended separately. Then, the aneurysmatic hepatic artery segment was resected, and the gastroduodenal artery stump was ligated. An end-to-end anastomosis was formed between the left and common hepatic arteries, followed by an end-to-end anastomosis formed between the right hepatic artery and splenic artery using a splenic artery transposition graft. Postoperative follow-up examinations showed that both hepatic arterial circulations were good, and no splenic infraction had developed.

Purpose. To investigate the extrahepatic collateral arteries related to hepatic artery occlusion (HAO) and to determine its benefits in the transarterial management of liver tumors.Methods and Findings. Eleven patients (7 hepatocellular carcinomas, 3 liver metastases, and 1 with hemangioma) with HAO confirmed with digital subtraction angiography (DSA) were admitted to our hospital. Of the 11 patients, 7 were men and 4 were women, with an average age of 41.5 ± 15.5 years (range: 29 to 70 years). DSA was performed to evaluate the collateral routes to the liver. In the 11 patients with HAO, DSA showed complete occlusion of the common hepatic artery in 9 patients and the proper hepatic artery (PHA) in 2 patients. Extrahepatic collateral arteries supplying the liver were readily evident. The collateral arteries originated from the superior mesenteric artery (SMA) in 8 patients, from the gastroduodenal artery in 2 patients, and from the left gastric artery (LGA) in 1 patient. Transcatheter treatment was successfully performed via the collateral artery in all patients except the one who had hemangioma.Conclusions. DSA is an effective method for detecting collateral circulation related to HAO and may provide information to guide transcatheter management decisions.

In this study the arterial vascular supply of the upper abdominal organs in the rat was investigated. In general the main anatomical features seem to be in accordance with the anatomy in man. However there are some important differences worth mentioning and the nomenclature used in the rat is not adequate in all respects: 1. The branch of the celiac artery which bifurcates into the hepatic artery proper and the gastroduodenal artery should not be given the incorrect name hepatic artery but is named common hepatic artery. 2. The hepato-esophageal artery is a constantly present branch of the hepatic artery proper running in the hepatogastric ligament. 3. The right gastric artery, present in about 40% of the specimens, is a branch of the gastroduodenal artery which runs towards the lesser curvature where it communicates freely with a left gastric artery branch. 4. The gastrosplenic artery is one of the branches of the splenic artery. It divides into a gastric and a splenic branch. The gastric branch is the only short gastric artery present in the rat. 5. A gastro-epiploic artery at the splenic side of the stomach is not present in the rat. The continuation of the splenic artery into the greater omentum has been referred to as the left epiploic artery. Anastomoses with epiploic branches of the gastro-epiploic artery are present in the greater omentum.
