We report the case of a 54-year-old female who presented with chronic mesenteric ischemia symptoms which could also be provoked on walking 50-100 m. Computed tomography angiography demonstrated ostial occlusion of all 3 mesenteric vessels, with extensive collateralization reconstituting the inferior mesenteric artery from the iliac arteries. As such, her abdominal pain was secondary to preferential flow to the lower limbs stealing from mesenteric vasculature. Endovascular management was trialed, but failed after short-term improvement, so the patient underwent successful transposition of inferior mesenteric to left common iliac artery. Mesenteric ischemia presenting with pain on walking secondary to preferential flow to the lower limbs has not been previously reported, and vascular and general surgeons should be aware of this unusual differential for abdominal pain.

Objectives: Squamous cell carcinoma of the anal canal (SCCA) is a rare condition. Standard treatment includes chemoradiotherapy, with surgical treatment reserved for limited cases. In the future, the decrease in surgical frequency makes it more difficult to pathologically assess the depth of tumor invasion and lymph node status; therefore, those studies based on relatively recent surgical cases may offer valuable insights into diagnosing and treating SCCA.

Objectives: To report the technical and clinical outcomes of endovascular repair of all infrarenal, penetrating aortic ulcers (PAU) that were treated at a single institution over a 13-year period.
Methods: This is a single-center, retrospective observational study. All patients consecutively treated for atherosclerotic, infrarenal PAU were included between 2010 and 2023.

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.

Objective: Loss of function of the phospholipid scramblase (PLS) TMEM16F results in Scott Syndrome, a hereditary bleeding disorder generally attributed to intrinsic platelet dysfunction. The role of TMEM16F in endothelial cells, however, is not well understood. We sought to test the hypothesis that endothelial TMEM16F contributes to hemostasis by measuring bleeding time and venous clotting in endothelial-specific knockout (ECKO) mice.

Purpose: We present the case of a rare extrahepatic portocaval shunt that resulted in communication of the portal vein and the inferior vena cava (IVC) at the level between two right renal veins that was incidentally diagnosed with contrast-enhanced computed tomography (CECT) in an asymptomatic patient.
Methods: A woman in her sixties with abdominal pain and diarrhea of unclear origin underwent exploratory abdominal CECT.
Results: The CECT incidentally revealed an extrahepatic portocaval shunt, whereby a vessel arising from the portal vein superior to the confluence of the superior mesenteric and splenic veins drained into the posterior aspect of the IVC between two right renal veins.
