We describe a case of initially unresectable locally advanced intrahepatic cholangiocarcinoma that showed remarkable regression after transcatheter arterial chemoembolization with degradable starch microspheres, allowing for subsequent successful curative resection. A 75-year-old female was referred to our hospital with a large hepatic mass. Computerized tomography examination showed a huge mass in ...

Arterial complications are a major source of morbidity and mortality after orthotopic liver transplantation (OLT). The incidence of hepatic artery thrombosis (HAT) ranges from 1.6% to 8%, with a mortality rate that ranges from 11% to 35%. We have described herein a technique of arterial anastomosis aiming to perform the ...

An extended hepatectomy combined with preoperative portal venous embolization can offer curative resection in patients with initially unresectable hepatocellular carcinoma. However, hypertrophy of the future remnant liver is occasionally unsatisfactory after portal venous embolization in some patients to remove the initially unresectable tumor. In these patients, hepatic venous reconstruction to ...

BACKGROUND/AIMS: Hemorrhage occurs in 15-25% of duodenal ulcers, mostly on the posterior wall of the proximal duodenum. Erosion of the gastroduodenal artery is responsible for serious hemorrhages. Therefore, the relationship between bile duct and gastroduodenal artery should be discerned to prevent bile duct injury. METHODOLOGY: Cadavers from 52 Chinese adults ...

Hepatic artery aneurysms represent about 20% of all visceral aneurysms and 0.01-0.2% of all arterial aneurysms. The authors report on a good risk patient with small infra-renal aortic aneurysm (AAA) and a large hepatic artery aneurysm. An excision and vein grafting of the hepatic artery aneurysm has been performed. The ...

The increased use of interventional procedures and laparoscopic cholecystectomy in the management of hepatobiliary disorders is associated with an increased incidence of hemobilia and hepatic artery aneurysm. Here we report a case of hepatic artery pseudoaneurysm associated with a plastic biliary stent. Multiple factors were involved in the formation of ...

BACKGROUND: It is difficult and challenging to reconstruct hepatic venous outflow in adult right lobe living donor liver transplantation (LDLT) without the middle hepatic vein (MHV). Excessive perfusion of the portal vein and venous outflow obstruction will lead to acute congestion of the graft, ultimately resulting in primary nonfunction. Although ...

The anatomy of the mesenteric system and the hepatic arterial bed has been demonstrated to have a high degree of variation. This is important when considering pre-surgical planning, catheterization, and trans-arterial hepatic therapies. Although anatomical variants have been well described, the characterization and understanding of regional hepatic perfusion in the ...

Transcatheter arterial chemoembolisation is the mainstay of treatment for patients with unresectable hepatocellular carcinoma. In patients with poor liver function, superselective catheter placement is necessary to prevent treatment-induced liver failure. Herein, the authors describe a case of a hepatocellular carcinoma successfully treated by superselective transcatheter arterial chemoembolisation using three-dimensional rotational ...

Fewer than 10% of patients with major liver trauma have life-threatening bleeding. Laparoscopic operations, endoscopic procedures, and percutaneous interventions such as drainages, vascular or tumor sclerosis, biopsies, and transjugular intrahepatic portocaval shunt (TIPS) have increased the number of iatrogenic vascular and bile duct injuries. Due to its therapeutic success, arterial ...

Hepatic arterial therapy with yttrium-90 microspheres exploits the avenue provided by the neoplastic microvasculature to deliver high-energy, low-penetrating therapeutic doses of radiation. Variant hepatic arterial anatomy, collateral vessels, and changes in flow dynamics during treatment can affect particle dispersion and lead to nontarget particle distribution and subsequent gastrointestinal morbidity. Awareness ...

Hepatic arterial infusion chemotherapy employs a hepatic artery catheter as a conduit to achieve a high concentration of antineoplastic agents to liver tumors. Historically, this catheter placement has been performed via laparotomy. However, it may now be performed using less-invasive percutaneous image guided procedures. There are many anatomical hepatic arterial ...

The hepatic artery plays an important role in the nourishment of liver parenchyma. The arterial distribution generates debate on where the artery terminates in the liver although is accepted that terminal branching of hepatic artery opened into sinusoids and form arterio-portal anastomosis. This implies that sinusoids are fed by both ...

Control of bleeding from the transected liver basically consists of vascular inflow occlusion and control of hepatic venous backflow from the caval vein. Central venous pressure determines the pressure in the hepatic veins and is an extremely important factor in controlling blood loss through venous backflow. Vascular inflow occlusion (Pringle ...
