Portal vein thrombosis (PVT) is frequent in patients with liver cirrhosis and possible severe complications such as mesenteric ischemia are rare, but can be life-threatening. However, different aspects of clinical relevance, diagnosis and management of PVT are still areas of uncertainty and investigation in international guidelines. In this article, we elaborate on PVT classification, geographical differences in clinical presentation and standards of diagnosis, and briefly on the current pathophysiological understanding and risk factors...

Standard hormone therapy for menopausal women [conjugated equine estrogen (CEE) 0.625 mg] has been associated with increased risk of venous thrombosis. Regimens containing lower CEE dose (0.30 mg) have been clinically used to decrease side effects of supra-physiological doses of estrogen. In this study, we determined the effects of standard (SD) and low (LD) dose of CEE on venular function in ovariectomized (OVX) spontaneously hypertensive rats (SHR). Contractions to Angiotensin-II (Ang-II 10μM) in perfused mesenteric venular bed were markedly increased in OVX (21...

Portal Vein Thrombosis (PVT) is caused by various thrombophilic states. PVT secondary to underlying vasculitis especially Churg-Strauss disease is among the rarest presentation. Here, we report a case of peripheral eosinophilia, eosinophilic ascitis and venous thrombosis involving portal vein and superior mesenteric vein diagnosed as Churg-Strauss Syndrome (CSS). He was managed with steroids and anticoagulants. Following initiation of steroids, eosinophilia and eosinophilic ascitis improved.

Patients with large spontaneous splenorenal shunt (SRS) prove challenging during liver transplantation (LT), irrespective of organizing portal vein (PV) thrombosis. Here, we detail the clinical outcomes of 26 patients who underwent direct ligation of large SRS during LT. Direct ligation of large SRS was applied in poor portal flow during LT. We performed temporary test clamping of the SRS before direct ligation and applied PV pressure monitoring in patients who showed signs of portal hypertension, such as bowel edema...

Foodborne illnesses are common and are usually considered as part of the differential diagnosis when a patient presents with gastrointestinal symptoms including nausea, vomiting, abdominal pain, diarrhea and fever. The majority of foodborne illness is transient and self-limited, while life threatening complications are rare. Here, we describe a case of a patient presenting with inflammatory diarrhea after consumption of undercooked seafood. She developed mesenteric and portal venous thrombosis and small bowel infarction requiring surgical intervention and resection of gangrenous small bowel...

A 43-year-old man had a peritoneovenous shunt inserted for the treatment of chylous ascites secondary to myelofibrosis. Despite being on anticoagulation for superior mesenteric vein thrombosis, he developed shunt dysfunction within two weeks of insertion. Superior venacavography showed multiple filling defects in the right axillary vein, no filling of the right brachiocephalic and right subclavian vein, and thrombotic occlusion of the internal jugular veins bilaterally. The shunt was removed 11 days after insertion, and there was extensive thrombosis of the venous end of the shunt and the compressible pump chamber...

Acute mesenteric venous thrombosis (MVT) is a rare, but life-threatening medical phenomenon. MVT is normally characterized by insidious onset, with nonspecific signs and symptoms. A high index of clinical suspicion is required for diagnosis, and emergency surgery is necessary to optimize the chances of patient survival, especially in the people aged more than 70 years. Surprisingly, based on my review of the literature, no fatal acute MVT case has been reported in the forensic literature. All reported such cases have been documented in medical literature, and most of them have been associated with underlying risk factors for venous thrombosis, such as hypercoagulable state, certain cancers, and stasis of the blood flow...

Acute superior mesenteric venous thrombosis (ASMVT) is an intractable disease with poor prognosis. Argatroban, a direct thrombin inhibitor, may be a novel anticoagulant method in the therapy of ASMVT. The aim of the present study was to assess the efficacy and safety of early argatroban therapy in ASMVT patients. The current retrospective study reviewed a consecutive series of ASMVT patients receiving early argatroban therapy during hospitalization between March 2013 and April 2014, with 18 ASMVT patients included in the study...

BACKGROUND: Thrombosis persists as a leading cause of morbidity and mortality. Given that endothelial cells (ECs) play a central role in regulating thrombosis, understanding the molecular endothelial cues that regulate susceptibility or resistance to thrombosis have important translational implications. Accordingly, we evaluated the role of endothelial autophagy in the development of thrombosis. METHODS: We generated mice in which the essential autophagy-related 7 (ATG7) gene was conditionally deleted from ECs (EC-ATG7(-/-) mice)...

Imaging of the mesenteric vasculature is crucial in diagnosing vascular disease of the gastro-intestinal tract such as acute or chronic mesenteric ischemia caused by arterial stenosis, embolism or thrombosis, mesenteric vein thrombosis and mesenteric aneurysm or dissection. The reference standard for imaging of the mesenteric vasculature is digital subtraction angiography. However, modalities as duplex ultrasonography, computed tomography angiography and magnetic resonance angiography are developing rapidly and may provide accurate imaging non-invasively...

The modern treatment of acute mesenteric ischemia (AMI) requires seamless collaboration of gastrointestinal surgeons, vascular surgeons, and interventional radiologists. The treatment strategy is straightforward aiming at rapid restoration of blood flow to the intestine. Bowel resection is performed on demand. The first thing to consider is the patient's clinical condition at presentation, whether there are signs of peritonitis or not, and whether the patient is hemodynamically stable or not. Second, there are four etiologies of AMI that need to be distinguished as they differ in treatment: superior mesenteric artery embolism, mesenteric arterial occlusive disease, mesenteric venous thrombosis, and non-occlusive mesenteric ischemia...

Anders Gottsäter
Visceral arteries such as the coeliac (CA), superior mesenteric (SMA), and the inferior mesenteric artery (IMA) might be affected by atherosclerotic occlusive lesions with or without thrombosis or embolization causing ischaemic symptoms from the gastrointestinal tract. After treatment of an acute event, these patients should be offered both non-pharmacological and pharmacological secondary prevention to reduce risk for future ischaemic arterial manifestations. Patients with mesenteric ischaemia caused by atherosclerosis should be evaluated concerning platelet antiaggregation with low dose aspirin or clopidogrel, and those with cardioembolic disease should be recommended anticoagulant treatment with either warfarin or one of the direct oral anticoagulants (DOAC; apixaban, dabigatran, edoxaban, or rivaroxaban)...
