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.

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.

Department of Internal Medicine, Saint Francis Presence Hospital, Evanston, IL, USA.

Venous thromboembolism (VTE) is a recognized extraintestinal manifestation of inflammatory bowel disease (IBD), with deep venous thrombosis (DVT) and pulmonary embolism being reported as the most frequent vascular complications in IBD patients. Much less frequently, arterial thromboembolic events may also be associated with greater morbidity and mortality. Aortic mural thrombosis is a rare phenomenon described in patients with IBD that often results in serious consequences such as visceral infarction and acute ischemia of the lower extremities.

Surgical Treatment of Wilkie's Syndrome by Vascular Transposition.

Cureus 2022 Apr 18;14(4):e24251. Epub 2022 Apr 18.

General Surgery Department, Imam Abdulrahman Alfaisal Hospital, Riyadh, SAU.

Introduction Superior mesenteric artery syndrome (SMAS), also called mesenteric duodenal compression syndrome, Wilkie's syndrome, chronic duodenal ileus or cast syndrome, is a rare clinical condition defined as a compression of the third portion of the duodenum in between the SMA and abdominal aorta (AA), due to narrowing of the space between them. SMAS is primarily attributed to loss of the intervening mesenteric fat pad, leading to partial or complete duodenal obstruction. Its manifestations are complex and non-specific, including postprandial epigastric pain, nausea, vomiting, early satiety, weight loss and anorexia. Read More

Internal Medicine, Centro Hospitalar Tâmega e Sousa, Penafiel, PRT.

The coronavirus disease 2019 (COVID-19) disease is a multisystem disease and recent studies have shown an increase in reported thromboembolic complications as deep venous thrombosis, pulmonary embolism (PE), stroke, and less frequently mesenteric artery thrombosis. We present a case of a 75-year-old woman, COVID-19 positive with five days of evolution, who was admitted to the emergency room due to diffuse abdominal pain with several days of progression, along with diarrhea and biliary vomit. Abdominal computed tomography presented images of subtraction of the lumen of the upper mesenteric artery. Read More

Department of Radiology, Rigshospitalet, Copenhagen, Denmark.

In this case report, we outline a tailored approach for a complex patient with acute in chronic proximal occlusive mesenteric disease complicated with fresh thrombosis and a heavily calcified aorta, where the standard treatment proved suboptimal. We outline the surgical considerations that ultimately led to performing a hybrid procedure of open thrombectomy combined with retrograde open mesenteric stenting of the superior mesenteric artery. The patient was a 75-year-old male, with a history of severe arteriosclerosis presenting with abdominal pain over 48 h. Read More

Schistosoma japonicum is a parasitic worm that lives in the mesenteric vein of its host and feeds on blood, suggesting that it might be a natural resource of novel anticoagulants. Here, by comprehensive analyses of the genomic sequences of Schistosoma japonicum, a new Kunitz-type gene precursor was identified. The Kunitz-type gene precursor codes for an 18-residue signal peptide and a 60-residue mature peptide. Read More

Platelet CFTR inhibition enhances arterial thrombosis via increasing intracellular Cl concentration and activation of SGK1 signaling pathway.

Acta Pharmacol Sin 2022 Mar 3. Epub 2022 Mar 3.

Department of Pharmacology, Zhongshan School of Medicine, Sun Yat-sen University, Guangzhou, 510080, China.

Platelet hyperactivity is essential for thrombus formation in coronary artery diseases (CAD). Dysfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) in patients with cystic fibrosis elevates intracellular Cl levels ([Cl]) and enhanced platelet hyperactivity. In this study, we explored whether alteration of [Cl] has a pathological role in regulating platelet hyperactivity and arterial thrombosis formation. Read More

Gastroduodenal artery pseudoaneurysm and chronic superior mesenteric vein thrombosis treated with transcatheter embolization and stent dilatation, respectively: 7 year clinical and imaging follow-up.

Radiol Case Rep 2022 Mar 23;17(3):1013-1020. Epub 2022 Jan 23.

Department of Radiology, Robert Larner M.D. College of Medicine, University of Vermont Medical Center, 111 Colchester Ave, Burlington, VT 05401, USA.

Pancreatic pseudocyst formation, arterial pseudoaneurysm, and splanchnic vein thrombosis are complications of chronic pancreatitis that account for significant morbidity and mortality in this patient population. While the short-term utility of timely endovascular intervention for treating the vascular complications of chronic pancreatitis have been relatively well documented, there is a paucity of longitudinal follow-up in this patient population, therefore making it difficult to predict the long-term efficacy of these interventions. This report details a case of a gastroduodenal artery pseudoaneurysm embolization followed by symptomatic superior mesenteric vein chronic thrombosis treated by stent dilatation in a patient with chronic pancreatitis, with 7 years clinical and imaging follow-up.

Subclavian versus femoral arterial cannulations during extracorporeal membrane oxygenation: A propensity-matched comparison.

J Heart Lung Transplant 2022 05 10;41(5):608-618. Epub 2022 Jan 10.

University Lille, CHU Lille, Cardiac Surgery, Lille, France.

Background: During peripheral extracorporeal veno-arterial membrane oxygenation (VA-ECMO) support, subclavian arterial cannulation provides, in comparison to femoral arterial cannulation, an anterograde flow which may prevent from left ventricular (LV) distention and improve outcomes. We aimed to compare the effectiveness of subclavian cannulation to femoral cannulation in reducing LV overdistension consequences, hemostatic complications and mortality.

Methods: This retrospective study conducted in two intensive care units of the Lille academic hospitals from January 2013 to December 2019 included 372 non-moribund adult patients supported by VA-ECMO. Read More

Do Natural Portosystemic Shunts Need to Be Compulsorily Ligated in Living Donor Liver Transplantation?

J Clin Exp Hepatol 2022 Jan-Feb;12(1):29-36. Epub 2021 Apr 24.

Centre for Liver and Biliary Sciences, Max Super Speciality Hospital, 1, Press Enclave Road, Saket, New Delhi, 110017, India.

Background: Natural portosystemic shunt ligation practices in liver transplant vary widely across transplant centres and are frequently undertaken to prevent the serious consequence of portal steal phenomenon. No concrete indications have so far been convincingly identified for their management in living donor liver transplant.

Methods: We retrospectively studied the outcome of 89 cirrhotic patients who either did (n = 63) or did not (n = 25) undergo shunt ligation during living donor liver transplantation between 2017 and 2020. Read More

Department of Radiology, University of Missouri, One Hospital Dr., Columbia, MO 65212, USA.

Thromboembolism is a recognized complication in patients with COVID-19 infection. It is believed that coagulopathy results secondary to severe inflammatory response syndrome with release of cytokines, viral activation of coagulation cascade or viral related vasculitis. Both arterial and venous thromboembolic complications have been described, however venous thromboembolic complications are much far common. Read More
