Background And Purpose: Percutaneous spine biopsies for spondylodiscitis have been long discussed due to the low microbiologic yield. This retrospective study evaluated factors of cone beam computed tomography-guided spine biopsies that may affect microbiologic yield.

Methods: We retrospectively reviewed percutaneous spine biopsies under cone beam computed tomography for spondylodiscitis performed from January 2015-December 2020.

Current assessment and management of endoleaks after advanced EVAR: new devices, new endoleaks?

Introduction: In recent years there has been an increasing application of advanced EVAR techniques to tackle complex clinical and anatomical scenarios. In a bid to overcome the limitations of the traditional stent-grafts, newer EVAR endografts and techniques have been developed and introduced into clinical practice, permitting endovascular management of difficult infrarenal, juxta-renal and thoracoabdominal aneurysms for which previously there was no endovascular solution. As a consequence, we are now confronted with unique patterns of endoleak requiring customized clinical-radiological assessment and treatment.

Computed Tomography Angiography findings can predict massive bleeding in head and neck tumours.

Purpose: The aim of our study was to assess CT angiography findings of head and neck tumours in predicting carotid blow out syndrome (CBS).

Method: We retrospectively reviewed the records of patients with head and neck cancer who underwent invasive angiography for CBS at our Institution from July 2013-2019. All routine CT angiography scans were assessed for the following findings with a univariate logistic regression analysis: 1) 360 ° involvement of the suspect artery by the tumour; 2) tissue or tumour necrosis, which was defined as an hypodense area with lack of contrast enhancement in the soft tissues of the neck or tumour mass, adjacent to the suspected vessel; 3) calibre reduction of the culprit artery; 5) jugular vein infiltration.

Provisional Stenting Using the Zilver PTX Drug-Eluting Stent After Drug-Coated Balloon Angioplasty: Initial Experience From the Double Drug Dose "3D" Study.

To explore the provisional use of a drug-eluting stent (DES) after suboptimal drug-coated balloon (DCB) angioplasty in complex, calcified femoropopliteal lesions. A prospective, single-center, investigator-initiated pilot study enrolled 15 patients (mean age 71.3 years; 9 men) with symptomatic stenosis (n=6) or occlusion (n=9) of the native superficial femoral and/or proximal popliteal arteries who experienced suboptimal DCB dilation despite postdilation.

Updated Clinical and Radiological Classification of Lower Limb Atherosclerotic Disease.

Lower limb atherosclerotic disease has classically been classified as acute or chronic; however, this is an evolving process that has a wide spectrum of clinical and imaging aspects. Owing to the evolvement of endovascular and imaging techniques, we have now garnered new information regarding the pathophysiology and behavior of atherosclerotic disease, also in response to endovascular and surgical techniques. Clinical presentation can actually be classified according to the time of presentation, ranging from acute (<2 weeks) and subacute (from 2 weeks to 3 months) to chronic (over 3 months) and acute/subacute on underlying chronic disease.

Current Status of Distal Embolization in Femoropopliteal Endovascular Interventions.

The application of advanced endovascular techniques in very complex femoropopliteal atherosclerotic lesions has shown to expose patients to a higher risk of distal embolization (DE). This complication can affect both the short- and long-term outcomes, leading to worsening ischemia, early minor/major amputation, and longer hospital stay. Recently, there has been an increasing body of evidence on pathophysiology and clinical-radiological management of DE that however has not been systematically addressed by guidelines.

Aortic Dissection: Novel Surgical Hybrid Procedures.

The management of patients with aortic dissection is challenging and its treatment is an area of development and innovation. Conventional surgical techniques are associated with significant risks in terms of mortality and morbidity in such high-risk patients. As a result of cumulative advances in technology, classical surgical techniques have been improved and enhanced by the newer endovascular approaches, leading to novel surgical hybrid procedures.

Updated Management of Malignant Biliary Tract Tumors: An Illustrative Review.

The management of malignant biliary tumors (MBTs) is complex and requires a multidisciplinary approach. Guidelines and methods of staging for biliary tumors have recently been released by main international societies, altering the clinical and radiologic approach to this pathologic condition. The aim of the present review is to detail the updated role of imaging in preoperative staging and follow-up and to illustrate clinical/therapeutic pathways.

Endovascular Repair of Acute and Chronic Aortic Type B Dissections: Main Factors Affecting Aortic Remodeling and Clinical Outcome.

Objectives: The aim of this study was to assess factors influencing the clinical outcome and morphological changes of acute and chronic type B aortic dissection after thoracic endovascular aortic repair (TEVAR).

Background: Aortic remodeling after TEVAR may be associated with clinical outcome, complications, and endoleak development.

Methods: Sixty cases of TEVAR for complicated type B acute aortic dissection (AAD) (n = 29) and chronic aortic dissection (CAD) (n = 31) with a minimum follow-up of 3 years were retrospectively reviewed.

Risk management in radiology.

Recent US nationwide research on malpractice lawsuits shows that the most common cause of medical malpractice suits against radiologists was error in diagnosis (mainly failure to diagnose instead of delay); the category next in frequency was procedural complications, followed by inadequate communication with either patient or referring physician. Risk management is a fundamental instrument to prevent and limit errors and adverse events. This article analyzes risk management in radiology addressing the most common ethical-legal issues on appropriateness of prescriptions, informed consent, and management of adverse events.

Fatal self administration of tramadol and propofol: a case report.

We describe a case of unintentional intoxication due to tramadol and propofol self administration, occurred in a middle aged man, healthcare provider, deceased despite advanced medical assistance an hour later the onset of severe and increasing dyspnea. Toxicological analysis performed with gas chromatography-mass spectrometry in blood sample, evidenced a lethal tramadol concentration and therapeutic level of Propofol. Quantitative determination was also performed in other specimens such as bile, tissues (liver, spleen, kidney) and pubic hair, to assess chronic exposure.

Malpractice in radiology: what should you worry about?

Over recent years the professional role of the radiologist has been evolved due to the increasing involvement in the clinical management of the patient. Radiologists have thus been increasingly charged by new duties and liabilities, exposing them to higher risks of legal claims made against them. Malpractice lawsuits in radiology are commonly related to inappropriate medical care or to the poor physician-patient relationship.

New "lethal highs": a case of a deadly cocktail of GHB and Mephedrone.

Drug scenes within several countries have changed in recent years to incorporate a range of licit psychoactive products collectively known as "legal highs": these in combination with substances already in use can cause major health problems and even death. Consumption of Gamma-hydroxybutyric acid (GHB) spread from 1980s to 2000s, when several nations have enacted laws that have made it illegal. Cases of GHB-caused or related deaths are often described in association with alcohol or traditional drugs (heroin, cocaine, amphetamine); few cases of acute lethal toxicity due to Mephedrone have been recently reported; we describe the first case of fatality due to concomitant consumption of GHB and Mephedrone.
