Endovascular straightening of the internal carotid artery during mechanical thrombectomy: The "tightrope technique".

Mechanical thrombectomy is a standard treatment for acute stroke, but it can be technically challenging in elderly patients with difficult vascular anatomy. To overcome this issue, we propose a new endovascular approach called the "tightrope" technique. This technique uses a stiff guidewire and a standard angiographic catheter to straighten the internal carotid artery (ICA) tortuosity, allowing the guiding catheter to be positioned next to the intracranial level.

PET/CT with F-choline or F-FDG in Hepatocellular Carcinoma Submitted to Y-TARE: A Real-World Study.

Our aim was to assess the role of positron emission computed tomography (PET/CT) with 18F-choline (18F-FCH) or 18F-fluorodeoxyglucose (18F-FDG) in hepatocellular carcinoma (HCC) submitted to 90Y-radioembolization (90Y-TARE). We retrospectively analyzed clinical records of 21 HCC patients submitted to PET/CT with 18F-fluorocholine (18F-FCH) or 18F-fluodeoxyglucose (18F-FDG) before and 8 weeks after 90Y-TARE. On pre-treatment PET/CT, 13 subjects (61.

Pneumonia Frequency and Severity in Patients With Symptomatic COVID-19: Impact of mRNA and Adenovirus Vector Vaccines.

Additional evidence of the role of COVID-19 vaccination in reducing pneumonia frequency and severity in the setting of breakthrough infection could help combat ongoing vaccine hesitancy. The purpose of this article was to compare the frequency and severity of pneumonia on chest CT in patients with confirmed COVID-19 between patients who are unvaccinated and those who are fully vaccinated by messenger RNA (mRNA) or adenovirus vector vaccines. This retrospective single-center study included 467 patients (250 men, 217 women; mean age, 65 ± 17 [SD] years) who underwent chest CT between December 15, 2021, and February 18, 2022, during hospitalization for symptomatic COVID-19, confirmed by reverse transcriptase-polymerase chain reaction assay.

Diagnostic accuracy and interobserver variability of CO-RADS in patients with suspected coronavirus disease-2019: a multireader validation study.

Objective: To conduct a multireader validation study to evaluate the interobserver variability and the diagnostic accuracy for the lung involvement by COVID-19 of COVID-19 Reporting and Data System (CO-RADS) score.

Methods: This retrospective study included consecutive symptomatic patients who underwent chest CT and reverse transcriptase-polymerase chain reaction (RT-PCR) from March 2020 to May 2020 for suspected COVID-19. Twelve readers with different levels of expertise independently scored each CT using the CO-RADS scheme for detecting pulmonary involvement by COVID-19.

Atrial Metastasis From Sarcomatoid Renal Cell Carcinoma: Integration Between 18F-FDG PET/CT and Cardiac 3-Dimensional Volume Rendering.

We describe the case of a 54-year-old woman, previously submitted to nephrectomy for sarcomatoid renal cell carcinoma and treated with antibiotics because of central venous catheter infection. An F-FDG PET/CT scan was obtained that demonstrated bone and lymph node metastases and also disclosed an irregular area of highly increased uptake (SUVmax 19.4) in the right atrium.

Spontaneous pneumomediastinum as the only CT finding in an asymptomatic adolescent positive for COVID-19.

The typical findings on CT in patients affected by novel COVID-19 (coronavirus disease 2019) pneumonia are characterized by ground-glass opacities and/or air space consolidation mainly bilateral and peripherical in distribution, including crazy paving pattern and reversed halo sign. We hereby describe a case of an adolescent male tested positive for COVID-19 with mild respiratory symptoms and presenting with pneumomediastinum as the only CT finding.

Treatment of visceral artery aneurysms and pseudoaneurysms with the use of cerebral flow diverting stents: initial experience.

Background: Flow-diverter stents (FDS) are designed to maintain laminar flow in the parent artery and sidebranches and to promote thrombosis of the aneurysm. Although these devices were developed for use in intracranial circulation, FDS could be employed to treat aneurysms regardless of their location, when anatomic factors may limit the efficacy of classic endovascular techniques. The objective of this study is to describe the initial experience of a single center in the treatment of visceral artery aneurysms and pseudoaneurysms (VAA-VAP) with cerebral FDS, analyzing safety, efficacy and 1-year outcome.

Percutaneous Pharmaco-Mechanical Thrombectomy of Acute Symptomatic Superior Mesenteric Vein Thrombosis.

Purpose: To evaluate the safety and the efficacy of percutaneous pharmaco-mechanical thrombectomy (PPMT) of acute superior mesenteric vein (SMV) thrombosis.

Methods: A database of patients treated between 2011 and 2018 with acute venous mesenteric ischemia (VMI) was reviewed. VMI was diagnosed in the presence of SMV thrombosis and CT evidence of jejunal thickening.

Treatment of thyroid nodules with radiofrequency: a 1-year follow-up experience.

Purpose: The aim of this study is to assess the effectiveness and safety of radiofrequency ablation (RFA) in debulking benign solid thyroid nodules.

Materials And Methods: This is a retrospective review of 77 patients with predominantly solid thyroid nodules treated with RFA in a single center between 2013 and 2016. All patients declined or were not eligible for surgery.

Trans Arterial Embolization of Non-variceal Upper Gastrointestinal Bleeding: Is the Use of Ethylene-Vinyl Alcohol Copolymer as Safe as Coils?

Purpose: The safety of liquid embolics over the conventional coils for the treatment of non-variceal upper gastrointestinal bleeding (UGIB) approach is still unclear. Purpose of this study is to assess the safety of ethylene-vinyl alcohol copolymer (EVOH 6%) over coils in the treatment of UGIB.

Materials And Methods: All the upper gastrointestinal tract embolization procedures performed in a single center in a 6-year period were reviewed.

Management of acute lower limb ischemia associated with the Angio-Seal arterial puncture closing device.

Arterial percutaneous closure devices (APCD) could lead to severe vascular complications, like acute lower limb ischemia. The aim of this study was to evaluate retrospectively our personal series of acute lower limb ischemia following the use of APCD. From January 2004 to June 2009 the Angio-Seal percutaneous closure devices was deployed in 198 patients.
