	Hepatic Artery Abnormalities: Blood Vessel Disorders of the Liver: Merck Manual Home Edition
		The hepatic artery carries oxygen-rich blood to the liver from the heart or its branches.
		Treatment of ischemic hepatitis is concentrated on treating the underlying cause and thereby restoring blood flow to the liver.
		An aneurysm may be treated by inserting a catheter into the hepatic artery and injecting an irritating substance that causes a clot to form, thereby blocking the artery.

		The preoperative evaluation for the 72 patients was performed using duplex sonography, abdominal CT scan, and angiography of the hepatic artery.
		Reconstructions of hepatic artery were performed between the branch patches of gastroduodenal/hepatic or splenic/common hepatic artery confluence of the donors and recipients, and an end-to-end anastomosis between other arterial vessels of the donors and recipients was done.
		Subsequently the pseudoaneurysm was successfully embolized and the blood flow toward the donor liver in hepatic artery remained.

	The hepatic artery: a reminder of surgical anatomy
		The left hepatic artery arose from the left gastric artery in 15%, and either the splenic, gastroduodenal artery or the aorta in 4% of cases.
		In 103 consecutive dissections, the middle hepatic artery arose from the right or left hepatic arteries in 82 instances (80%), the gastroduodenal in nine, the superior mesenteric and splenic in two instances each, the left gastric and common hepatic arteries in one instance each and was not identified in six dissections.
		The left gastric artery arose from the splenic in two instances and the aorta in one, and the gastroduodenal artery arises from the coeliac axis and from the right hepatic artery in one instance, respectively.

	eMedicine - Liver Transplantation, Complications : Article by Paul D Russ
		Disruption of hepatic artery flow results in biliary ischemia or necrosis and subsequent biliary strictures, bile leaks, bilomas, infected bilomas, and frank intrahepatic abscesses.
		In most patients, direct Doppler evaluation of hepatic artery anastomosis is not possible because the donor-recipient arterial anastomosis is tortuous, because it is in an inconsistent position, and because it is usually obscured by overlying bowel gas.
		Unlike the native biliary tree that is supplied by collaterals from the gastroduodenal artery, the harvested donor bile duct and the anastomotic end of the recipient duct are solely dependent on the hepatic artery.

	Hepatic Artery Embolization
		Hepatic artery embolization is an effective therapeutic option for patients with liver metastases from GIST.
		HAE is performed by instilling microscopic particles into a lobar hepatic artery or selectively into one of its branches in order to occlude the major arterial supply to the tumors (Figure 1).
		Rarely, cholecystitis or pancreatitis occurs due to inadvertent embolization of the cystic or gastroduodenal arteries.

		Causes of hepatic artery occlusion include thrombosis (eg, due to hypercoagulable states, severe arteriosclerosis, vasculitis), embolus (eg, due to endocarditis, tumors, therapeutic embolization, chemoembolization), iatrogenic causes (eg, ligation at surgery), vasculitis, hepatic artery aneurysm, toxemia of pregnancy, cocaine use, and sickle cell crisis.
		Aneurysms of the hepatic artery tend to be saccular and multiple.
		Although congenital anomalies of the hepatic artery are common, they are rarely clinically important; they may be noted during vascular imaging tests or surgery.

	Liver Note (Site not responding. Last check: )
		Although the hepatic artery only supplies 20% of the blood to the liver, its blood is oxygenated and it is the sole contributor to the biliary tree in the liver.
		Of clinical importance is hepatic artery patency and flow, as survival of the graft depends on this.
		Flowprobes provide a volumetric measure of hepatic artery flow, and when this is low can be used to determine if there is a fixed anatomic limitation to flow or a physiologic limitation.

	Hepatic artery infusion of chemotherapy
		Infusion of chemotherapy directly into the hepatic artery (HAI) to minimize the side effects of the chemotherapy is an option in selected patients with liver cancer or metastatic spread of cancer to the liver.
		Hepatic artery infusion of chemotherapy has also been used in patients after liver resection (removal) for colorectal cancer spread to the liver.
		Even with progressive increase in hepatic tissue replacement, physical symptoms tended to occur late in the course of the disease.The development of fully implanted pumps allows the patient to be mobile and reduces the need for frequent clinic visits for drug infusion.

		The difference between the two procedures is that in chemoembolization, additional material is injected to block (embolize) the small branches of the hepatic artery.
