A simultaneous superior mesenteric arterial and venous thrombosis in an elderly woman with a previous COVID-19 pneumonia: A suggestive case report diagnosed at computed tomography angiography.

Radiol Case Rep 2022 Aug 11;17(8):2869-2873. Epub 2022 Jun 11.

MD at Radiology Unit of Riuniti Hospital, Azienda Ospedaliera Grande Ospedale Metropolitano (G.O.M.) "Bianchi-Melacrino-Morelli", Reggio, Calabria, Italy.

Superior mesenteric artery (SMA) and superior mesenteric vein (SMV) thrombotic occlusion is a rare but potentially fatal condition. Though isolated mesenteric arterial occlusion associated with COVID-19 has been reported in literature, combined superior mesenteric arterial and venous thrombosis is very rare. We report the case of an 88-years-old woman with a combined superior mesenteric arterial and venous thrombotic occlusion with a previous COVID-19 pneumonia of about 15 days before, diagnosed at computed tomography angiography (CTA) scan.

Gut-Derived Exosomes Induce Liver Injury After Intestinal Ischemia/Reperfusion by Promoting Hepatic Macrophage Polarization.

Inflammation 2022 Jun 14. Epub 2022 Jun 14.

Department of Anesthesiology, Nanfang Hospital, Southern Medical University, 1838 Guangzhou Ave N, Guangzhou, 510515, China.

Liver injury induced by intestinal ischemia/reperfusion (I/R) is accompanied by the polarization of Kupffer cells, which are specialized macrophages located in the liver. However, the causes of hepatic macrophage polarization after intestinal I/R remain unknown. This study investigated whether gut-derived exosomes contribute to the pathogenesis of liver injury triggered by intestinal I/R in a murine model and explored the underlying mechanisms. Read More

Vasopressors and Risk of Acute Mesenteric Ischemia: A Worldwide Pharmacovigilance Analysis and Comprehensive Literature Review.

Front Med (Lausanne) 2022 23;9:826446. Epub 2022 May 23.

Service de Médecine Intensive Réanimation, Centre Médico-Chirurgical Ambroise Paré, Neuilly-sur-Seine, France.

Vasodilatory shock, such as septic shock, requires personalized management which include adequate fluid therapy and vasopressor treatments. While these potent drugs are numerous, they all aim to counterbalance the vasodilatory effects of a systemic inflammatory response syndrome. Their specific receptors include α- and β-adrenergic receptors, arginine-vasopressin receptors, angiotensin II receptors and dopamine receptors. Read More

Outcomes of Vasoconstrictor-Induced Non-Occlusive Mesenteric Ischemia of Colon: A Systematic Review.

Clin Med Res 2022 Jun 8. Epub 2022 Jun 8.

Division of Gastroenterology and Nutrition, Loyola University Medical Center, Maywood, IL.

Background: Nonocclusive mesenteric ischemia (NOMI) is due to mesenteric arterial hypoperfusion from several causes, such as hypovolemia, heart failure, shock, vasoconstrictors, and severe liver or renal disease. Vasoconstrictor-induced NOMI is usually iatrogenic or associated with cocaine use.

Objectives: Anecdotal reports suggest that cocaine-induced NOMI has the highest mortality among vasoconstrictors. Read More

Nonocclusive mesenteric ischemia caused by type B aortic dissection: a case report.

BMC Surg 2022 Jun 3;22(1):214. Epub 2022 Jun 3.

Second Affiliated Hospital of Soochow University, Suzhou, China.

Background: Nonocclusive mesenteric ischemia (NOMI) is defined as acute intestinal ischemia because of decreased blood flow in mesenteric vessels. Only a few cases of NOMI that occur secondary to aortic dissection (AD) have been reported, resulting in the lack of sufficient knowledge of diagnosis and treatment.

Case Presentation: We aimed to report a case of NOMI caused by type B Aortic Dissection. Read More

Hypogastric Artery Flow Interruption is Associated with Increased Mortality After Open Aortic Repair.

Ann Vasc Surg 2022 May 30. Epub 2022 May 30.

Division of Vascular and Endovascular Surgery, Department of Surgery, New York University Langone Medical Center, New York, NY. Electronic address:

Background: Potential complications of pelvic flow disruption during aortic aneurysm repair include buttock ischemia and mesenteric ischemia. Unilateral or bilateral hypogastric artery flow interruption, either from atherosclerosis or intentionally to facilitate aneurysm repair, is considered problematic in endovascular repair; however, it has not been well studied in open abdominal aortic aneurysm (AAA) repair (OAR). We sought to examine the effect of interruption of flow to one or both hypogastric arteries on outcomes after OAR. Read More

Involvement of β-adrenoceptors in the cardiovascular responses induced by selective adenosine A and A receptor agonists.

Pharmacol Res Perspect 2022 Jun;10(3):e00975

Division of Physiology, Pharmacology and Neuroscience, School of Life Sciences, University of Nottingham, Nottingham, UK.

A and A adenosine receptors produce regionally selective regulation of vascular tone and elicit differing effects on mean arterial pressure (MAP), whilst inducing tachycardia. The tachycardia induced by the stimulation of A or A receptors has been suggested to be mediated by a reflex increase in sympathetic activity. Here, we have investigated the role of β - and β -adrenoceptors in mediating the different cardiovascular responses to selective A and A receptor stimulation. Read More

Unusual computed tomography findings of gas in the superior mesenteric artery system with no signs of porto-mesenteric venous gas in a case of acute mesenteric ischemia.

Radiol Case Rep 2022 Jul 20;17(7):2568-2572. Epub 2022 May 20.

Department of Radiological Sciences, Oncology and Pathology, "Sapienza" University of Rome - I.C.O.T. Hospital, Via Franco Faggiana, 1668, 04100, Latina, Italy.

Acute Mesenteric Ischemia (AMI) is a rare life-threatening entity caused by sudden interruption of the blood supply to a segment of the bowel due to impairment of mesenteric arterial blood flow or venous drainage. Clinical presentation varies according to the time course of vascular occlusion. Contrast-enhanced Computed Tomography (CT) of the abdomen represents the main diagnostic test for AMI diagnosis, enabling fast and excellent evaluation of the intestine, mesenteric vasculature, and other ancillary characteristics of AMI.

Sildenafil-Induced Revascularization of Rat Hindlimb Involves Arteriogenesis through PI3K/AKT and eNOS Activation.

Int J Mol Sci 2022 May 16;23(10). Epub 2022 May 16.

MITOVASC, Equipe CarMe, CNRS 6015, Inserm 1083, Angers Université, 49100 Angers, France.

Hypoxia and inflammation play a major role in revascularization following ischemia. Sildenafil inhibits phosphodiesterase-5, increases intracellular cGMP and induces revascularization through a pathway which remains incompletely understood. Thus, we investigated the effect of sildenafil on post-ischemic revascularization. Read More
