The Role of CT-guided Core Needle Biopsy in Pancreatic Tumors: An Initial Evaluation in Modern Oncology.

Purpose: Neoadjuvant chemotherapy has recently become the standard of care for borderline resectable pancreatic ductal adenocarcinoma (PDAC), and there have even been numerous reports evaluating its potential benefits in resectable PDAC. However, neoadjuvant therapy first requires a histological or cytological diagnosis. This study aimed to analyze the safety and diagnostic yield of CT-guided core needle biopsy (CNB).

Endovascular Management of Iatrogenic Renal Vascular Injuries: Case Series and Systematic Review.

Unlabelled: Minimally invasive techniques for the treatment and diagnosis of kidney disease seek to preserve the greatest amount of parenchyma. Bleeding after these practices is rare, but must be treated quickly given its severity. Iatrogenic renal vascular injuries (IRVI) resulting from these procedures include active bleeding, arterial pseudoaneurysms, and arteriovenous fistulas.

Rectus sheath hematoma: conservative, endovascular or surgical treatment? A single-center artificial neural network analysis.

Purpose: Rectum sheath hematoma (RSH) is a rare and often misdiagnosed disease. We aimed to determine outcomes of patients affected by RSH and identify variables associated with the need of prompt intervention.

Methods: Patients diagnosed with RSH during the period 2012-2020 were retrospectively identified.

Ibero-American Society of Interventionism (SIDI) and the Spanish Society of Vascular and Interventional Radiology (SERVEI) Standard of Practice (SOP) for the Management of Inferior Vena Cava Filters in the Treatment of Acute Venous Thromboembolism.

Objectives: to present an interventional radiology standard of practice on the use of inferior vena cava filters (IVCFs) in patients with or at risk to develop venous thromboembolism (VTE) from the Iberoamerican Interventional Society (SIDI) and Spanish Vascular and Interventional Radiology Society (SERVEI).

Methods: a group of twenty-two interventional radiologist experts, from the SIDI and SERVEI societies, attended online meetings to develop a current clinical practice guideline on the proper indication for the placement and retrieval of IVCFs. A broad review was undertaken to determine the participation of interventional radiologists in the current guidelines and a consensus on inferior vena cava filters.

Three-dimensional virtual and printed models for planning adult cardiovascular surgery.

Background: The objective of this study was to explore the usefulness of virtual models and three-dimensional (3D) printing technologies for planning complex non-congenital cardiovascular surgery.

Methods: Between July 2018 and December 2019, adult patients with different cardiovascular structural diseases were included in a clinical protocol to explore the usefulness of Standard Tessellation Language (STL)-based virtual models and 3D printing for prospectively planning surgery. A qualitative descriptive analysis from the surgeon's viewpoint was done based on the characteristics, advantages and usefulness of 3D models for guiding, planning and simulating the surgical procedures.

COVID-19 pneumonia accurately detected on chest radiographs with artificial intelligence.

Purpose: To investigate the diagnostic performance of an Artificial Intelligence (AI) system for detection of COVID-19 in chest radiographs (CXR), and compare results to those of physicians working alone, or with AI support.

Materials And Methods: An AI system was fine-tuned to discriminate confirmed COVID-19 pneumonia, from other viral and bacterial pneumonia and non-pneumonia patients and used to review 302 CXR images from adult patients retrospectively sourced from nine different databases. Fifty-four physicians blind to diagnosis, were invited to interpret images under identical conditions in a test set, and randomly assigned either to receive or not receive support from the AI system.

[Endovascular treatment of an hepatic artery pseudoaneurysm following pancreaticoduodenectomy].

Pseudoaneurysm formation is a serious complication in the context ofa pancreatic resection, reaching out a high mortality rate. Classically, surgery was the gold standard of treatment, but nowadays endovascular approach has been accepted as the first treatment option. The use of covered stents seems to be a safe and effective tool to treat this serious complication.

[Abusive head trauma: report of a case].

The abusive head trauma is a form of child abuse. The most frequent injuries are intracranial lesions, such as subdural hematoma, as well as retinal hemorrhages, usually without other external injuries. Due to its complexity, this problem requires a multidisciplinary medical team, where the role of the radiologist is important, since there are multiple diagnostic methods that are complementary in order to arrive at the correct diagnosis.

Transhepatic venous approach for balloon-assisted cervical collateral venous access.

Central venous catheter placement is indicated in many situations, and an increasing number of patients require temporary and long-term central catheters. Frequently, patients who have undergone multiple central veins catheterizations develop complete and diffuse venous occlusion, and this constitutes a difficult-to-manage clinical problem. We report a case of a 20-year-old patient who was referred to our department for central venous line placement who manifested bilateral femoral, jugular, and subclavian veins occlusion.

Percutaneous pediculoplasty in osteoporotic compression fractures.

Percutaneous pediculoplasty is a vertebroplasty-complementary technique that can be carried out with one needle for each single approach. This report describes five cases of osteoporotic vertebral and pedicular compression fractures that were treated with percutaneous vertebroplasty and bilateral pediculoplasty with use of polymethylmethacrylate and high-quality fluoroscopic guidance. All patients reported complete pain relief.

[Percutaneous implant of Hickman catheters and reservoirs. Long-term experience].

Objective: To report our experience with long term external catheters and implantable ports in the last 8 years.

Material And Methods: From December 1987 to August 1995 a total of 617 central venous catheters were implanted in 541 patients in our Interventionist Vascular Radiology Unit, 265 men (49%) and 276 women (51%), with a mean age of 46 years. A total of 335 (54%) were partially implantable external catheters and 241 (39%) implantable ports in chest and 41 (7%) in the forearm.
