Summary of key guidelines for locoregional treatment of HCC in Asia, Europe, South and North America.

Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide accounting for over 800,000 new cases in 2018, with the highest incidence in Asia and Africa where hepatitis B is the most common risk factor. In Europe, Japan, and the United States, hepatitis C chronic alcohol abuse and non-alcoholic fatty liver disease are more common risk factors. Five-year survival is low, less than 20% worldwide.

Performance of Ultrasonography Compared to Conventional Radiography for the Diagnosis of Osteoarthritis in Patients With Knee Pain.

To investigate the performance of ultrasonography (US) for the detection of knee osteoarthritis (OA) in patients suffering from knee pain, compared to conventional radiographs. Cross-sectional study performed at a university teaching hospital. Consecutive patients complaining of unilateral or bilateral mechanical knee pain who signed an informed consent were included.

Cadaveric Specimen Study of Prostate Microvasculature: Implications for Arterial Embolization.

Purpose: To describe the prostatic microvasculature anatomy and to measure the diameter of the intraprostatic vessels from human cadaveric specimens.

Material And Methods: The prostates of 18 white males (35-68 years of age; mean prostate volume, 60.11 mL) were fixed in a solution of phosphate-buffered 10% formaldehyde and processed histologically with hematoxylin and eosin stain, Masson trichrome stain, immune peroxidase, and immunofluorescence.

Intraoperative stent placement for the treatment of acute portal vein complications in pediatric living donor liver transplantation.

Purpose: Pediatric living donor liver transplantation (LDLT) in low weight recipients remains one of the most complex surgical procedures, with portal vein (PV) complications occurring in up to 19% of cases. When decreased PV flow is diagnosed intra- or perioperatively, intraoperative stent placement is a good substitute for surgical adjustment. Still, at the present moment, little is known about the technical feasibility, safety, efficacy, and long-term outcome of intraoperative stenting in LDLT.

Endovascular treatment of paravisceral mycotic aneurysm: Chimmeny endovascular sealing the end of de road.

Open surgery is the elective treatment for mycotic aneurysms of the aorta. This surgery consists of resection of the aneurysm, debridement and revascularization with an in situ or extra-anatomic bypass. Even when surgery has been successful, the morbi-mortality is raised and the endovascular treatment has become an alternative for specific patients.

Stent tunnel technique to save thrombosed native hemodialysis fistula with extensive venous aneurysm.

Introduction And Purpose: The increasing number of patients undergoing hemodialysis and the limited number of access sites have resulted in an increasing number of techniques to maintain vascular access for hemodialysis. Thrombosed arteriovenous (AV) fistulas with large venous aneurysms have poor treatment results, with both endovascular and surgical techniques, leading to a high rate of definitive AV access loss. The purpose of this study was to review the feasibility and initial results of this novel endovascular treatment of thrombosed AV fistulas with large venous aneurysms.

Randomized controlled trial of irinotecan drug-eluting beads with simultaneous FOLFOX and bevacizumab for patients with unresectable colorectal liver-limited metastasis.

Background: Reports have demonstrated the superior activity of combining both irinotecan and oxaliplatin (FOLFOXIRI) therapy. An option for gaining similar benefits with less toxicity would be the administration of irinotecan through a hepatic artery approach. The aim of this study was to assess the response and adverse event rates for irinotecan drug-eluting beads (DEBIRI) with folinic acid, 5-fluorouracil, and oxaliplatin (FOLFOX) and bevacizumab as a first-line treatment for unresectable colorectal liver metastasis.

Usefulness of MRI in takotsubo cardiomyopathy: a review of the literature.

Takotsubo cardiomyopathy (TC) is a disease that can be misinterpreted as a more serious acute coronary syndrome. Its clinical characteristics resemble those of a myocardial infarct, while its imaging characteristics are critical on correctly characterizing and diagnosing the disease. From angiography, where coronary anatomy is evaluated, to cardiac magnetic resonance (CMR), where morphology and tissue characterization is assessed, the array of imaging options is quite extent.

Pneumo-CT assessing response to neoadjuvant therapy in esophageal cancer: Imaging-pathological correlation.

Pneumo-computed tomography (PnCT) is a technique primarily developed and used to study stenotic lesions of the esophagus, gastroesophageal junction and stomach for pre-surgical planning. It helps to define both upper and lower borders of neoplasms located in the aforementioned areas. It achieves maximum lumen distension with CO2 highlighting thickened areas of the esophageal wall, thus allowing an accurate quantification of their extents.

New surgical strategy to induce liver hypertrophy: role of MDCT-volumetry to monitor and predict liver growth.

Background/aims: To describe the role of MDCT-volumetry to monitor and predict liver hypertrophy in a recently introduced surgical technique in patients needing hepatectomy.

Methodology: This prospective study was approved by the local research and ethics committee and patient informed consent was obtained. Twelve consecutive patients were selected for associating liver partition and portal vein ligation for staged-hepatectomy procedure.

[Superselective embolization in the treatment of massive gastrointestinal bleeding].

Introduction: Massive lower gastrointestinal (LGI) bleeding is a severe clinical picture associated with high mortality in hospitalized patients with comorbidities. Current international publications have highlighted the role of embolization in the treatment of this pathology, although there is little experience in Latin America. The aim of this paper is to describe a series of cases treated in the same institution using embolization as safe and effective treatment of massive LGI bleeding.
