Unlabelled: This case report addresses segmental arterial mediolysis (SAM), a rare non-inflammatory vasculopathy. A 51-year-old man presented at the emergency department for epigastric and left upper quadrant pain. He had a history of arterial hypertension and had recently received methylprednisolone for knee pain. Blood tests revealed elevated C-reactive protein levels at 40 mg/l and lactate dehydrogenase levels at 496 IU/ml. Abdominal computerized tomography showed arterial thickening, arterial dilatations, and dissections of the splenic and renal arteries, leading to organ ischemia. This case emphasizes the importance of considering SAM in cases of unexplained abdominal pain or suspected arteriopathy.
Learning Points: Segmental arterial mediolysis (SAM) is a rare and underdiagnosed vasculopathy.SAM is a challenging diagnosis and should not be confused with vasculitis.SAM has a good prognosis with spontaneous resolution in most cases.

Objective: This study aims to develop and validate an enhanced computed tomography (CT)-based radiomics model to differentiate gastric schwannomas (GS) from gastrointestinal stromal tumors (GIST) across various risk categories.
Methods: This retrospective analysis was conducted on 26 GS and 82 GIST cases, all confirmed by postoperative pathology. Data was divided into training and validation cohorts at a 7:3 ratio.

Contrary to cardiovascular risk reductions by aerobic exercise, arterial stiffness, as assessed by brachial-ankle pulse wave velocity (PWV), is higher in swimmers and controls than in other aerobically trained individuals. The main muscles actively recruited in swimming are in the upper limbs, so this study aimed to investigate heart-brachial PWV in swimmers and to compare arterial stiffness indices between modes and measurement localities. Subjects comprised 60 individuals (18-22 years), including 20 untrained controls (Con), 20 aerobically trained cyclists (Aero), and 20 swimmers (Swim).

Objective: The impact of great saphenous vein harvest technique on infrainguinal bypass outcomes remains a matter of debate, with no robust evidence favoring a specific technique over the other. This study aims to compare the outcomes of open vein harvest with endoscopic vein harvest in patients undergoing infrainguinal bypass surgery.
Methods: Patients who underwent an infrainguinal bypass from a femoral origin using a single-segment great saphenous vein between 2011 and 2023 were identified in the Vascular Quality Initiative infrainguinal bypass module.

Near-miss traffic risk estimation using Extreme Value Theory (EVT) models within a real-time framework offers a promising alternative to traditional historical crash-based methods. However, current approaches often lack comprehensive analysis that integrates diverse roadway geometries, crash patterns, and two-dimensional (2D) vehicle dynamics, limiting both their accuracy and generalizability. This study addresses these gaps by employing a high-fidelity, 2D time-to-collision (TTC) near-miss indicator derived from autonomous vehicle (AV) sensor data.

Background: Quantitative flow ratio (QFR) can identify functionally significant coronary disease non-invasively. Myocardial contrast echocardiography (MCE) is a non-invasive and effective procedure for detecting abnormalities in hemodynamic coronary artery stenosis. Currently, there is no research confirming the correlation between MCE and QFR.
