Two cases of posttraumatic aneurysms of splanchnic arteries were referred to Istituto di Chirurgia Generale e Cardiovascolare del-l'Università di Milano (Italy) during 1989, and are the subject of this report. In both the instances a history of blunt abdominal trauma was collected, and histology confirmed the characters of false aneurysms of the lesions. The arteries involved were the middle colic and the splenic, respectively, with a long lasting history of recurrent abdominal pain related with particular physiologic events (e.g. meals or effort) only in the first case. The physiopathology, clinical feature, and problems related to surgical treatment in each cases are discussed in detail.

Non-Occlusive Mesenteric Ischemia in Aortic Surgery: What You Need to Know.

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.

Background And Aims: The adipocyte-derived adiponectin (APN) has potent insulin-sensitizing and anti-inflammatory properties. The adipose tissue is known to be the main source for APN in the circulation, but sites and mechanisms which remove APN from blood are still unknown in humans.
Methods And Results: We reviewed APN data obtained in previous studies in which the inter-organ exchange of amino acids and cytokines was measured in our laboratory.
The pan-PPAR agonist lanifibranor reduces portal pressure independent of fibrosis reduction through the splanchnic vasculature.

Portal hypertension (PH) can cause severe complications in patients with advanced chronic liver disease (aCLD). The pan-peroxisome proliferator-activated receptor (pan-PPAR) agonist lanifibranor reduces portal pressure in preclinical models of aCLD. Since the effect on PH might be secondary to fibrosis improvement, we investigated the effect of lanifibranor on PH, hepatic and splanchnic angiogenesis in mouse models of fibrotic and prehepatic non-fibrotic PH.

Background: Vascular calcification is highly prevalent and associated with mortality in hemodialysis patients. However, extreme splanchnic arterial calcification in calciphylaxis with poor prognosis raises questions regarding the reliability of previous vascular calcification scoring methods. Therefore, this study aimed to examine the distribution characteristics of abdominal aortic branch calcification and identify a more reliable predictor of mortality in hemodialysis patients.

Elevated arterial ammonia is associated with several complications of liver disease as it predicts mortality for in-patients and decompensation, hospitalization and death in out-patients with cirrhosis. In this review, our aim was to estimate how the individual organs contribute to arterial ammonia based on published data from human studies. The brain removes ammonia from arterial blood in a concentration-dependent fashion.
