SASI (selective arterial secretin injection) is a form of ASVS (arterial stimulation and venous sampling) used to localize pancreatic gastrinomas. This report aims to review the protocol for SASI and demonstrate its utility in localizing functional and nonfunctional gastrinomas. Even if a patient has a pancreatic mass and a laboratory profile fitting a specific endocrine syndrome, these may or may not be associated as has been previously demonstrated with adrenal vein sampling. We present a case where a patient underwent simultaneous SASI and bland embolization of a hepatic metastasis to facilitate partial pancreatectomy for Zollinger-Ellison syndrome...

Two patients with placenta percreta underwent uterine artery embolization (UAE) for abnormally invasive placenta (AIP) in the first trimester. Patient 1 had a 9-week cervical ectopic, while Patient 2 had a 9-week cesarean scar pregnancy. Elective termination of pregnancy was performed in both patients. UAE was performed with tris-acryl gelatin microspheres as well as gelfoam until stasis and was repeated in cases of revascularization. Both patients were followed with US/MRI/MRA scans and β-hCG levels. Revascularization occurred in both patients following UAE, requiring multiple embolizations to achieve complete placental involution...

Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide. Only 30-40% of patients diagnosed with HCC are candidates for curative treatment options. The remaining majority of patients undergo local, regional or systemic palliative therapies. Transvascular therapy of HCC takes advantage of the fact that hypervascularized HCCs receive their main perfusion from the hepatic artery. In this context transvascular therapy describes different therapies: bland embolization (transarterial embolization, TAE), cTACE (conventional transarterial chemoembolization), DEB-TACE (TACE with drug-eluting beads, DEB) and SIRT (selective internal radiation therapy, radioembolization)...

BACKGROUND: Right ventricular (RV) dysfunction caused by acute pulmonary embolism (PE) is associated with poor short- and long-term prognosis. RV dilatation as a proxy for RV dysfunction can be assessed by calculating the right-to-left ventricle diameter (RV/LV) ratio on standard computed tomography pulmonary angiography (CTPA) images. It is unknown whether dedicated training is required to accurately and reproducibly measure RV/LV ratio therefore we aimed to assess these parameters in residents in internal medicine without experience in CTPA reading...

BACKGROUND: Radioembolization (RE) with intra-arterial administration of 90 Y microspheres is a promising technique for the treatment of liver metastases from small intestinal neuroendocrine tumors (SI-NET) not amenable to surgery or local ablation. However, studies comparing RE to other loco-regional therapies are lacking. The aim of this randomized study was to compare the therapeutic response and safety after RE and bland hepatic arterial embolization (HAE), and to investigate early therapy-induced changes with diffusion-weighted MRI (DWI-MRI)...

Management of hepatocellular carcinoma (HCC) can be maximized with the utilization of multiple treatment modalities including transplant, surgical resection and locoregional therapies including ablative therapies and transarterial embolotherapies. Although transplant and surgical resection offer the best clinical outcomes, a limited number of patients are amenable to these surgical treatment options due to the advanced disease at presentation. Transarterial embolotherapies including conventional transarterial chemoembolization (cTACE), bland transarterial embolization (TAE), drug-eluting beads transarterial chemoembolization (DEB-TACE) and selective internal radiation therapy (SIRT) with Yttrium 90 (90Y) have played an increasingly important role for these patients with unresectable HCC...

BACKGROUND: The optimal transcatheter embolization strategy for patients with unresectable hepatocellular carcinoma (HCC) remains elusive. We conducted a systematic review and network meta-analysis (NMA) of different embolization options for unresectable HCC. METHODS: Medical databases were searched for randomized controlled trials evaluating bland transarterial embolization (TAE), conventional TACE, drug-eluting bead chemoembolization (DEB-TACE), or transarterial radioembolization (TARE), either alone or combined with adjuvant chemotherapy, or local liver ablation, or external radiotherapy for unresectable HCC up to June 2017...

Hepatocellular carcinoma (hcc) arising from a hepatic adenoma is a rare phenomenon accounting for fewer than 5% of hcc cases; it seldom recurs after resection of the primary tumour. We report a case of extrahepatic metastasis of hcc arising from a hepatic adenoma that presented as a solitary sternal metastasis without any evidence of intrahepatic recurrence. Our patient was initially treated with radiation therapy and bland embolization, without response. Subsequently, the patient developed progressive disease while taking sorafenib...

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...

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...
