Hepatic artery thrombosis following orthotopic liver transplant is one of the most common reasons for early graft failure. Meticulous reconstitution of hepatic artery flow remains essential for good outcomes. Prior surgery, body habitus, hepatic artery inadequacy and anatomic differences can complicate hepatic artery revascularization. We report a single institution's experience, ...

BACKGROUND AND OBJECTIVES: Hepatic arterial infusion (HAI) chemotherapy offers improved hepatic control for liver metastases from colon cancer. Optimal catheter insertion requires an adequate gastroduodenal artery (GDA). Limited data exists on using saphenous vein grafts (SVG) as conduits when native vasculature is inadequate. METHODS: All HAI pump insertions from 7/99 ...

Hepatic artery stenosis or thrombosis following liver transplant is a potentially life-threatening complication. Successful liver transplant depends on uncompromised hepatic arterial inflow. Early diagnosis and treatment of complications prolong graft survival. Interventional radiologic techniques are frequently used to treat hepatic artery complications. Twenty patients with hepatic artery stenoses (n = ...

The variations in the morphological characteristics of the extra-hepatic biliary system are interesting. During the dissection of cadavers to study the morphological characteristics of the extra-hepatic biliary system, a 46-year-old male cadaver was found to have drainage of the common hepatic duct drains directly into the gall bladder neck. The ...

Malignant hypercalcemia without bone metastasis may result from the abnormal secretion of parathyroid hormone (PTH) or PTH-related protein (PTH-rP). We present a case of possible PTH-rP-secreting mixed hepato/cholangiocarcinoma. In July 2000, a 52-year-old woman presented with right hypochondrial pain and weight loss. Imaging procedures revealed a 10-cm lesion involving the ...

A six-year-old boy presented with cough, cyanosis and clubbing. Investigations revealed hypoxia (PaO2 53 mm Hg on room air) which was only partially correctable (PaO2 73 mm Hg) with 100% oxygen administered through a non re breathing face mask. Liver function tests showed elevated total bilirubin, and transaminases, liver biopsy ...

The right hepatic artery and the common hepatic artery originate from the superior mesenteric artery in approximately 10-15% of the population. Reconstruction of the hepatic artery using the gastroduodenal artery has previously been described to repair hepatic artery injury during the performance of biliary and pancreatic resections. We report the ...

Although amebic liver abscess is a common disease, it is a rare cause of venous thrombosis. Computed tomography (CT) scan is an ideal tool for diagnosing the various complications associated with liver abscess. We describe a case of amebic liver abscess in a patient who developed a rare vascular complication ...

Involvement of abdominal organs in Osler's disease may lead to the development of hepatic arteriovenous shunts with a dilatation of the hepatic artery. Right and subsequent global heart failure due to cardiac valvular insufficiency, pulmonary artery hypertension, and hepatomegaly as well as increased cardiac output may result. This hyperdynamic hepatic ...

Arterial rupture subsequent to angioplasty occurs in about 5% of cases. Thrombolysis with re-establishment of flow without resolving underlying anatomic defects such as hepatic arterial stenosis leads to re-thrombosis. We present a case of arterial anastomotic rupture after thrombolysis and angioplasty of an underlying anastomotic hepatic arterial stenosis. Both the ...

Pseudoaneurysm is a life-threatening complication after pancreaticoduodenectomy. An endovascular covered stent was employed for treatment of pseudoaneurysm of the common hepatic artery after pancreaticoduodenectomy. A 77-year-old female underwent pylorus-preserving pancreaticoduodenectomy for lower bile duct cancer. She complained of hematochezia but upper gastrointestinal endoscopy did not find a bleeding source. Angiography ...

Pseudoaneurysms of the hepatic artery are infrequent, but potentially fatal. Apart from the performance of percutaneous techniques, such lesions are fundamentally produced as a result of surgery. The causal surgical techniques may sometimes be quite complex, though in other cases they are very common (e.g. laparoscopic cholecystectomy). Knowledge of such ...

Experiments on dogs showed that pulmonary trunk stenosis increased the tone of arterial vessels in the liver and led to the development of veno-arterial and veno-venous reactions. The number of vessels with intimal musculature and myoelastic sphincters in the arterial bed increases, and muscle rolls in large hepatic veins are ...

We describe a unique method for obtaining distal control in a ruptured hepatic artery aneurysm. A 34-year-old man with Ehlers-Danlos syndrome type IV presented with a ruptured left hepatic artery aneurysm. The distal aneurysm was within the parenchyma of the liver. Proximal control was obtained with pledgeted sutures. The distal ...

Steno-occlusive disease (arterial obstructive disease) of the transplant hepatic artery is a collective term that can be used to include hepatic artery thrombosis, hepatic artery stenosis, and hepatic arterial kinks. The latter 2 can be referred to collectively as arterial anatomical defects. This chapter details the angiographic techniques and definitions ...

Nonocclusive arterial disease represents less than 5% of posttransplant arterial complications. Nonocclusive arterial complications are classified into (1) nonocclusive diminished flow in the hepatic artery, (2) arteriovenous fistulae, (3) pseudoaneurysms, and (4) arterial rupture. Due to the rarity of these complications, particularly when considering them individually, many of the opinions ...

Visceral artery aneurysms are rare lesions. They involve the hepatic artery in approximately 20% of cases. Various therapeutic options are available for patients with hepatic artery aneurysms (HAAs). Dictated predominately by the need to maintain distal end-organ perfusion, potential therapies include traditional surgical techniques and laparoscopic surgery, endovascular methods of ...
Teh Swee H - - 2007
BACKGROUND: There is a growing interest in using laparoscopy for hepatic resection. However, structured training is lacking in part because of the lack of an ideal animal training model. We sought to identify an animal model whose liver anatomy significantly resembled that of the human liver and to assess the ...

Hepatic arterial infusion chemotherapy can be of value to patients with metastatic liver disease from colorectal cancer. Arterial infusion therapy requires surgical placement of a catheter into the gastroduodenal artery connected to a subcutaneous infusion pump or port, a procedure involving major abdominal surgery. Placement of chemotherapy infusion catheters by ...

The proliferative capacity of non-ligated liver lobes was designned experimental study on dogs in which portal vein and hepatic artery ligation was done either simultaneously or heterochronously. Dogs were divided into four groups: G I (control G); laparotomy was performed without vascular ligation, G II; dogs were subjected to ligation ...

A 6-year-old girl underwent off-pump extracardiac Fontan completion. Intrapericardial inferior caval vein was found to be accompanied by the hepatic vein on the left side; a 20 x 10 x 10-mm bifurcated ePTFE graft was used without external shunting. This approach is practical for the surgeons and may result in ...

Polyarteritis nodosa is a systemic necrotising vasculitis that affects the small- and medium-sized arteries. Multifocal aneurysmal formation in the renal, hepatic, and mesenteric vasculature is a hallmark of this condition, and spontaneous aneurysmal rupture may occur, resulting in life-threatening haemorrhage. We describe a 42-year-old man who initially presented with fever ...

During laparoscopic hepatic resection, an abrupt decrease in FE'CO(2) (from 28 mmHg to 9 mmHg) associated with near cardiac arrest occurred concomitantly with hepatic vein laceration and the use of an argon beam coagulator system. During venous gas embolism, transesophageal echocardiography (TEE) proved the transpulmonary passage of the gas. In ...
