CT angiography prior to endovascular aortic surgery is the standard non-invasive imaging method for evaluation of aortic dimensions and access sites. A detailed report is crucial to a proper planning. We assessed Artificial Intelligence (AI)-algorithm accuracy to measure vessels diameters at CT prior to transcatheter aortic valve implantation (TAVI).

The patient, a 62-year-old woman with multiple comorbidities, experienced a pseudoaneurysm following an unintentional carotid artery puncture during a failed attempt to place a triple lumen catheter in the right jugular vein. Percutaneous thrombin injection was chosen as the treatment method, with Doppler ultrasound monitoring.

We report a case involving a 7-year-old boy, who was admitted to our CT scanning room because of an incidental discovery of low blood-oxygen levels (90-94% in good health). A persistent left SVC was depicted, with drainage in the left atrium and a resultant right-to-left shunt;right SVC was present, draining to the right atrium.

A 78-year-old male patient was admitted to our hospital after abdominal trauma. Contrast-enhanced computed tomography (CT) scan demonstrated a horseshoe kidney with a perinephric hematoma and evidence of arterial hemorrhage. An anomalous renal arterial anatomy was noted as well, with a renal artery originating from the left common iliac artery.

Most devices are self-expandable polytetrafluoroethylene-covered stent grafts (PTFE-SGs) that are dilated to their nominal diameter (8 or 10 mm). We investigated whether PTFE-SGs dilated to a smaller caliber (under-dilated TIPS) reduce PSE yet maintain clinical and hemodynamic efficacy.

Vasodilation leading to a hyperdynamic circulatory state is central in the development of a late decompensated stage, with inflammation currently considered a key driver. We aimed to assess hepatic/systemic hemodynamics and inflammation (by C-reactive protein [CRP]) among the different sub-stages of cirrhosis and to investigate their interrelationship and prognostic relevance.

We translate the results of a genome-wide high-throughput analysis into a tool that accurately predicts at presentation tumour growth and survival of patients with HCC.
Design: Ultrasound surveillance identified HCC in 78 (training set) and 54 (validation set) consecutive patients with cirrhosis.
Background: Schwannomas are the most common benign tumours developing in peripheral nerves. They usually present as a slow-growing mass, sometimes associated with pain and paraesthesia. The aim of this study is to define the correct preoperative diagnosis, to review the surgical treatment employed and to evaluate short- and long-term neurological deficits.

Methods: In a nonblinded, single-center study, 70 outpatients with cirrhosis (Child-Pugh classes B7-C10) with demonstrated patent portal veins and without hepatocellular carcinoma were assigned randomly to groups that were given enoxaparin (4000 IU/day, subcutaneously for 48 weeks; n = 34) or no treatment (controls, n = 36). Ultrasonography (every 3 months) and computed tomography (every 6 months) were performed to check the portal vein axis.
