INTRODUCTION: Mesenteric, splenic and portal veins thrombosis (MSPVT) is uncommon complication after sleeve gastrectomy. CASE REPORT: A 38-year-old female underwent laparoscopic sleeve gastrectomy (LSG) for the treatment of morbid obesity, presented 4 weeks later with epigastric pain. Computed tomography (CT) scan revealed superior mesenteric, splenic and the portal veins thrombosis. CONCLUSION: MSPVT is a rare presentation after laparoscopic sleeve gastrectomy, which requires early diagnosis and management and it should be included in the differential diagnosis for unexplained abdominal symptoms after laparoscopic sleeve gastrectomy...

A 33-year-old man of a Middle Eastern origin presented to us with abdominal pain and distension secondary to refractory ascites of 1-month duration. The patient had a history of taking oral retinoic acid 25 mg for 4 months for mycosis fungoides. Investigations revealed thrombosis of hepatic veins with extensive thrombosis of the porto-mesenteric axis. A combination of transjugular intrahepatic portosystemic shunt, balloon angioplasty and thrombolysis with recombinant tissue plasminogen activator was successfully used to treat his condition...

PURPOSE OF REVIEW: To describe portal vein thrombosis (PVT) in the setting of cirrhosis especially in relation to its potential impact on liver transplantation. In addition, the safety and efficacy of anticoagulation is reviewed. RECENT FINDINGS: PVT in cirrhosis occurs in up to 26% of patients awaiting liver transplantation. Different studies have suggested that PVT impacts negatively post-liver transplantation survival, particularly in first year post-liver transplantation and when PVT is complete involving the porto-mesenteric confluence and not allowing physiological anastomosis...

BACKGROUND: The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been shown to be valuable prognostic markers for a variety of pathological conditions including solid tumors, sepsis and others. However, the prognostic values of the NLR and PLR in patients with acute mesenteric arterial embolism (AMAE) and acute mesenteric arterial thrombosis (AMAT) have not been elucidated. The aim of this study was to determine the predictive value of the NLR and PLR for poor prognosis in patients with AMAE and AMAT...

Mesenteric ischemia is a rare disorder, with considerably high morbidity and mortality rates. It can manifest in several ways, including acute mesenteric ischemia, chronic mesenteric ischemia, nonocclusive mesenteric ischemia, mesenteric venous thrombosis, and colonic ischemia. Of these, acute mesenteric ischemia is the most severe form of intestinal ischemia, with a high mortality rate. The mainstay of therapy for mesenteric ischemia is surgical exploration and resection of infarcted bowel; however, medical therapy can play an important adjunctive role...

A 35-year-old man who previously underwent splenectomy for hereditary spherocytosis at age 29 visited our hospital complaining of fatigue that had started 7 days ago and right upper abdominal pain. Laboratory data showed increased white blood cell and eosinophil count accompanied by severe transaminitis and clotting abnormalities. Computed tomography scan showed multiple embolisms in the portal vein, superior mesenteric vein, right pulmonary artery, and inferior vena cava. Severe liver damage presumably caused by portal vein thrombosis was also observed...

Thrombosis, a critical event in blood vessels, not only is associated with myocardial infarction and stroke, but also accounts for considerable morbidity and mortality. Thrombolytic drugs are usually applied to the treatment of acute myocardial infarction, acute cerebral infarction and pulmonary embolism. However, thrombolytic drugs show limited efficacy in clinical practice because of the short half-life in plasma and systemic side effects. In this study, the cyclic RGD (cRGD) functionalized liposomes were prepared to encapsulate urokinase, a cheap and widely used thrombolytic drug in clinic and better thrombolysis efficacy was achieved...

A 45-year-old woman who required lifelong anticoagulation for recurrent thrombosis had her therapeutic choices limited by heparin-induced thrombocytopenia and abnormal pharmacokinetics (greatly reduced absorption) resulting from short gut syndrome from extensive gut resection after mesenteric thrombosis. As an alternative to inconvenient and expensive injections of fondaparinux, personalized dosing of a direct oral anticoagulant was sought using clinical pharmacology techniques. Enteral absorption was ascertained with small test doses of apixaban, and the ability of supraconventional doses to deliver effective concentrations was verified...

BACKGROUND: Acute mesenteric ischemia (AMI) is a serious and potentially fatal condition. No definite parameter can predict transmural bowel necrosis in patients with AMI to justify early surgical intervention. The current study aimed to identify the clinical, laboratory, and radiologic parameters that can successfully predict the onset of intestinal transmural necrosis in patients with AMI. PATIENTS AND METHODS: Records of patients with AMI in the period of January 2013 to October 2017 were reviewed...

RATIONALE: Acute mesenteric vein thrombosis (MVT) is defined as new-onset thrombosis of the mesenteric vein without evidence of collateralization, finally resulting in extensive intestinal infarction. MVT may be idiopathic or be caused by conditions responsible for thrombophilia and acquired risk factors. To date, there have been few reports of MVT after trauma. Herein we describe our experiences treating three patients with MVT. PATIENT CONCERNS: Case 1 was a 44-year-old man with transverse colon mesenteric hematoma after blunt abdominal trauma...

Surgeon-modified retrograde branched extension limb assembling technique and bridged endografts were successfully used to exclude an asymptomatic pararenal abdominal aortic aneurysm and to reconstruct the superior mesenteric artery and bilateral renal arteries in a case with high-grade celiac artery stenosis, nondilated aorta above the superior mesenteric artery, and large lumen below the renal arteries. In patient-specific models for hemodynamics analysis, enhanced flow diversion to visceral arteries up to 6-month follow-up confirmed treatment feasibility; however, endograft configurations could be improved to avoid sharp corners at bifurcations, thereby ensuring smooth flow transport and possibly reducing risk for endograft narrowing or the development of thrombosis...

Abdominal pain is a common occurrence, and it may vary from subtle pain to very severe pain due to a variety of causes, some of which may even be life-threatening. It is commonly believed that a life-threatening cause is almost always very severe with regards to the symptomatology. However, here in this case report, we report an unusual case of abdominal pain due to superior mesenteric vein (SMV) thrombosis in an otherwise healthy lady who was on an oral contraceptive agent for the last 2 years. She presented with mild abdominal pain for 3 days, and a computed tomography scan of the abdomen which was done to rule out common surgical causes of abdominal pain revealed a thrombus in the SMV...
