Hemodynamic processes from the portal vein(PV) to the inferior vena cava(IVC) were mimicked for three patients with portal hypertension(PH) and the effects of stent parameters on the outcomes of transjugular intrahepatic portosystemic shunt(TIPS) were investigated through computational fluid dynamics(CFD). The liver region was simulated with porous media model and the spatial distributions of superior mesenteric vein(SMV) and splenic vein(SV) blood were solved through the Eulerian multiphase model. The present method is able to simulate the PH flow and predict the PV pressure, the stent shunt rate and the SMV blood proportion after TIPS treatment.

Background: Non-invasive approach other than conventional endoscopy could be effectively used for screening and monitoring esophageal variceal bleeding (EVB).
Purpose: To retrospectively investigate the role of four-dimensional (4D) flow magnetic resonance imaging (MRI) as an add-on tool to endoscopy for predicting EVB in cirrhotic patients with esophageal varices (EVs).
Material And Methods: A cohort of 109 cirrhotic patients with EVs was divided into four groups: A = negative red color [RC] sign, no EVB, n = 60; B = negative RC sign, EVB, n = 13; C = positive RC sign, no EVB, n = 10; and D = positive RC sign, EVB, n = 26.
Non-Occlusive Mesenteric Ischemia in Aortic Surgery: What You Need to Know.
Ann Vasc Surg
January 2025
Institute of Cardiac and Aortic Disorders, SRM Institutes for Medical Science (SIMS Hospitals), Chennai, India.
Background: Nonocclusive mesenteric ischemia (NOMI), a subtype of acute mesenteric ischemia, is primarily caused by mesenteric arterial vasoconstriction and decreased vascular resistance, leading to impaired intestinal perfusion.Commonly observed after cardiac surgery, NOMI affects older patients with cardiovascular or systemic diseases, accounting for 20-30% of acute mesenteric ischemia cases with a mortality rate of ∼50%. This review explores NOMI's pathophysiology, clinical implications in aortic dissection, and the unmet needs in diagnosis and management, emphasizing its prognostic significance.

January 2025
Department of Radiology, University Medical Center Regensburg, 93053 Regensburg, Germany.
Background: Portal vein thrombosis (PVT) leads to portal hypertension (PH) with its sequelae. Computed tomography spleno-mesenterico-portography (CT-SMPG) combines sequential CT spleno-portography and CT mesenterico-portography. CT-SMPG comprehensively illustrates the venous hemodynamic changes due to PH.

Background: Obesity, a major risk factor for cardiovascular disease (CVD), is associated with hypertension and vascular dysfunction. Perivascular adipose tissue (PVAT), a metabolically active tissue surrounding blood vessels, plays a key role in regulating vascular tone. In obesity, PVAT becomes dysregulated which may contribute to vascular dysfunction; how sex impacts the remodelling of PVAT and thus the altered vascular contractility during obesity is unclear.
