Bland embolization

INTRODUCTION: Arterial blood sampling, used to assess patients in acute conditions, may result in complications such as thrombosis and embolism. However, it can be replaced by venous blood sampling, but there is a dearth of information on this. AIM: To assess the correlation and agreement between the arterial and central venous blood gases analyses in patients undergoing elective Coronary Artery Bypass Graft (CABG) surgery. MATERIALS AND METHODS: In this cross-sectional study, 100 ICU patients undergoing elective CABG surgery were recruited...

The management of hepatocellular carcinoma (HCC) remains challenging due to late presentation and the presence of accompanying liver dysfunction. As such, most patients are not eligible for curative resection and liver transplant. Management in this scenario depends on a number of factors including hepatic function, tumor burden, patency of hepatic vasculature and patients' functional status. Based on these, patients can be offered catheter based intra-arterial therapy for intermediate stage disease and in more advanced disease, sorafenib...

PURPOSE: Transulnar access (TUA) has been shown to be an effective alternative to transradial access (TRA) for coronary intervention. This study evaluates the safety and efficacy of TUA in patients undergoing visceral interventions in the setting of contraindication to TRA. MATERIALS AND METHODS: Patients who underwent visceral interventions via ulnar approach were included in the study. Outcome variables include technical success, access site and bleeding complications...

PURPOSE: The study sought to describe a single centre's technical approach to transradial intervention and report on clinical outcomes and safety. METHODS: A total of 749 transradial access (TRA) procedures were performed at a single hospital in 562 patients (174 women and 388 men). Procedures included 445 bland embolizations or chemoembolizations of the liver, 88 uterine artery embolizations, and 148 procedures for Selective Internal Radiation Therapy (Y90), which included mapping and administration...

AIM: To retrospectively compare the initial response, local recurrence, and complication rates of radiofrequency ablation (RFA) vs microwave ablation (MWA) when combined with neoadjuvant bland transarterial embolization (TAE) or drug-eluting microsphere chemoembolization (TACE) for the treatment of hepatocellular carcinoma (HCC). METHODS: A total of 35 subjects with Barcelona Clinic Liver Cancer (BCLC) very early and early-stage HCC (range: 1.2-4.1cm) underwent TAE (23) or TACE (12) with RFA (15) or microwave ablation (MWA) (20) from January 2009 to June 2015 as either definitive therapy or a bridge to transplant...

Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related deaths worldwide with rapidly growing incidence rates in the USA and Europe. Despite improving surveillance programs, most patients are diagnosed at intermediate to advanced stages and are no longer amenable to curative therapies, such as ablation, surgical resection and liver transplantation. For such patients, catheter-based image-guided embolotherapies such as transarterial chemoembolization (TACE) represent the standard of care and mainstay therapy, as recommended and endorsed by a variety of national guidelines and staging systems...

PURPOSE: Transarterial embolization is frequently used to treat local hepatocellular carcinoma (HCC). While various complications are known to occur following transarterial embolization, only one prior case of peritoneal spread of HCC occurring shortly after transarterial chemoembolization has been reported. We present five cases of peritoneal spread of HCC following transarterial embolization (including bland embolization, conventional transarterial chemoembolization (TACE), and doxorubicin-eluting beads TACE) and identify features common among those cases...

Percutaneous radiofrequency ablation (RFA) for the treatment of stage I renal cell carcinoma has recently gained significant attention as the now available long-term and controlled data demonstrate that RFA can result in disease-free and cancer-specific survival comparable with partial and/or radical nephrectomy. In the non-controlled single center trials, however, the rates of treatment failure vary. Operator experience and ablation technique may explain some of the different outcomes. In the controlled trials, a major limitation is the lack of adequate randomization...

Undifferentiated embryonal sarcomas of the liver are extremely rare cases in adults. We report the case of a 30-year-old male who presented with early satiety and abdominal pain due to a massive tumor originating from the left liver and occupying the entire epigastrium. The patient underwent bland embolization in an attempt to decrease the size of the tumor. He then underwent a formal left hepatectomy with resection of liver segments 2, 3, and 4. Extrahepatic inflow control of the portal vein and hepatic artery was performed prior to parenchymal transection...

Colorectal cancer is the third leading cause of cancer death in the United States. Although hepatic excision is the first-line treatment for colorectal liver metastasis (CRLM), few patients are candidates. Locoregional therapy (LRT) encompasses minimally invasive techniques practiced by interventional radiology. These include ablative treatments (radiofrequency ablation, microwave ablation, and cryosurgical ablation) and transcatheter intra-arterial therapy (hepatic arterial infusion chemotherapy, transarterial "bland" embolization, transarterial chemoembolization, and radioembolization with yttrium 90)...

RATIONALE AND OBJECTIVES: Intra-procedural measurement of hepatic perfusion following liver embolization continues to be a challenge. Blood volume imaging before and after interventional procedures would allow identifying the treatment end point or even allow predicting treatment outcome. Recent liver oncology studies showed the feasibility of parenchymal blood volume (PBV) imaging using an angiographic C-arm system. This study was done to evaluate the reproducibility of PBV measurements using cone beam computed tomography (CBCT) before and after embolization of the liver in a swine model...

BACKGROUND: Intra-arterial brachytherapy with yttrium-90 ((90)Y) resin microspheres (radioembolization) is a procedure to selectively deliver high-dose radiation to tumors. The purpose of this research was to compare the radioembolic effect of (90)Y-radioembolization versus the embolic effect of bland microspheres in the porcine kidney model. METHODS: In each of six pigs, ~25-33 % of the kidney volume was embolized with (90)Y resin microspheres and an equivalent number of bland microspheres in the contralateral kidney...

INTRODUCTION: Surgery for liver metastases in pancreatic neuroendocrine tumor (PNET) improves overall survival rate. We present the first case report for robotic multivisceral resection of distal pancreas, spleen, and left liver for metastatic PNET. MATERIALS AND METHODS: We present a case of 52-year-old female diagnosed with PNET in the pancreatic neck metastatic to the liver, responding to somatostatin and bland embolization, who underwent surgical debulking using da Vinci robotic platform...

PURPOSE: We tested the hypothesis that establishing a dedicated interventional oncology (IO) clinical service line would increase clinic visits and procedural volumes at a single quaternary care academic medical center. METHODS: Two time periods were defined: July 2012 to June 2013 (pre-IO clinic) and July 2013 to June 2014 (first year of dedicated IO service). Staff was recruited, and clinic space was provided in the institution's comprehensive cancer center. Clinic visits and procedure numbers were documented using the institution's electronic medical record and billing forms...

A 64-year-old patient developed sudden hypoglycemia leading to unconsciousness. Hypoglycemic episodes recurred on several occasions but were not accompanied by unconsciousness. Magnetic resonance imaging revealed a liver tumor in the right lobe sized 20.0 × 14.6 × 19.0 cm. No other masses were detected. Right hemihepatectomy was indicated but could not be performed due to heavy bleeding near the tumor. Histological examination showed a relatively cellular tumor made of elongated bland cells. The mitotic index was fewer than 4 mitoses per 10 HPF...

PURPOSE: To evaluate changes in T-cell populations in peripheral blood after bland hepatic artery embolization (HAE). MATERIALS AND METHODS: Bland HAE was performed in 12 patients to treat primary (n = 5) or metastatic (n = 7) liver tumors, using microspheres and polyvinyl alcohol (n = 8) or microspheres alone (n = 4). Patient peripheral blood samples were collected within 1 month before HAE, within 1 week after HAE (early period after HAE), and 2-8 weeks after HAE (follow-up period)...

Embolotherapies used in the treatment of hepatocellular carcinoma (HCC) include bland embolization, conventional transarterial chemoembolization (cTACE) using ethiodol as a carrier, TACE with drug-eluting beads and super absorbent polymer microspheres (DEB-TACE), and selective internal radiation therapy (SIRT). Successfully treated HCC lesions undergo coagulation necrosis, and appear as nonenhancing hypoattenuating or hypointense lesions in the embolized region on computed tomography (CT) and magnetic resonance...

(90)Y radioembolization refers to the selective, transcatheter, and intra-arterial injection of micrometer-sized particles loaded with the radioisotope yttrium-90 for the treatment of primary and metastatic hepatic malignancies. In the treatment of intermediate- and advanced-stage hepatocellular carcinoma, (90)Y radioembolization provides favorable outcomes with minimal side effects, offering an alternative treatment option to other transarterial therapies, such as bland embolization and chemoembolization. This review provides an overview of the use of (90)Y radioembolization in the treatment of hepatocellular carcinoma, including patient selection criteria, dosimetry, and clinical outcomes...

BACKGROUND: The unique situation of the liver with arterial and venous blood supply and the dependency of the tumor on the arterial blood flow make this organ an ideal target for intrahepatic catheter-based therapies. Main forms of treatment are classical bland embolization (TAE) cutting the blood flow to the tumors, chemoembolization (TACE) inducing high chemotherapy concentration in tumors, and radioembolization (TARE) without embolizing effect but very high local radiation. These different forms of therapies are used in different centers with different protocols...
