BACKGROUND In most instances, advanced neuroendocrine tumors follow an indolent course. Hepatic metastases are common, and although they can cause significant pain, incapacitating endocrinopathy, and even death, they are usually asymptomatic. The appropriate timing and efficacy of interventions, such as hepatic artery embolization (HAE) and operation,(More)
PURPOSE To evaluate and describe the prevalence of hepatic arterial variants seen at digital subtraction angiography in a large series of patients. MATERIALS AND METHODS Data were collected prospectively by using an arterial anatomy database questionnaire that was completed at the time each visceral angiographic examination was performed from May 1996 to(More)
PURPOSE To determine the survival of patients with hepatocellular carcinoma (HCC) treated with a standardized method of transcatheter arterial embolization (TAE) with small embolic particles intended to impart terminal vessel blockade, and to evaluate prognostic factors that impact overall survival. MATERIALS AND METHODS A total of 322 patients with HCC(More)
PURPOSE To describe patient- and procedure-related factors associated with post-biopsy pneumothorax and those that require intervention. MATERIALS AND METHODS Patient and procedure data from all lung biopsies performed at a single center between January 2000 and July 2001 were recorded prospectively. Data included patient demographics, lesion size, lesion(More)
PURPOSE A prospective, randomized trial was performed to determine if intra-abdominal drainage catheters are necessary after elective liver resection. PATIENTS AND METHODS Between April 1992 and April 1994, 120 patients subjected to liver resection, stratified by extent of resection and by surgeon, were randomized to receive or not receive operative(More)
OBJECTIVE The purpose of this study was to determine the incidence of variant intrahepatic portal vein anatomy detected on CT portography and to discuss surgical implications. CONCLUSION Variant portal vein anatomy is nearly as common as variant hepatic artery anatomy. The complexity of hepatic interventions now performed by interventional radiologists(More)
BACKGROUND Complete surgical resection is the mainstay of treatment for patients with hepatocellular carcinoma (HCC). Unfortunately, most patients ultimately develop disease recurrence and the median survival from the time of recurrence is <1 year. The purpose of the current study was to review the authors' experience using bland hepatic arterial(More)
Stent placement is an accepted primary treatment for SVC syndrome. Balloon dilation is frequently performed prior to stent placement. Although various stent-related hemorrhagic complications have been reported, as well as reports of iatrogenic catheter and guidewire perforations, there has been only one previous report of balloon dilation–related SVC(More)
PURPOSE To evaluate the outcome of all patients undergoing particle embolization for hepatocellular carcinoma at a single institution from January 1, 1993, through December 31, 1995. MATERIALS AND METHODS The charts and radiographs of all patients undergoing particle embolization during the study period were reviewed. The following information was(More)
OBJECTIVES The objectives of this study are 1) to determine whether the future liver remnant will grow after portal vein embolization (PVE) in patients with colon cancer on concurrent chemotherapy and 2) to determine whether recovery after extended hepatectomy is improved after PVE. PURPOSE Neoadjuvant chemotherapy followed by hepatic resection is an(More)
