Acute ischemia in chronic type B dissections carries high rates of morbidity and mortality. A 29-year-old woman with a chronic type B dissection presented with acute abdominal pain. Imaging revealed a worsening dissection with pseudocoarctation causing near complete occlusion of the true lumen by the false lumen. We placed purposefully undersized stent grafts to treat acute mesenteric ischemia by improving true lumen flow. The patient was discharged on postoperative day 4 without adverse events. We suggest that endovascular rescue by placing undersized stent grafts can provide improved flow to the mesenteric vessels with continued false lumen flow to vital organs...

OBJECTIVE: To evaluate the diagnostic potential of smooth muscle protein of 22 kDa (SM22) as plasma biomarker for the detection of transmural intestinal ischemia. BACKGROUND: Acute mesenteric ischemia is an abdominal emergency requiring rapid diagnosis and treatment. Especially, detection of transmural damage is imperative because it mandates emergency surgery. Since early clinical and radiological signs are nonspecific, there is an urgent need for accurate biomarkers...

AIM: Mangiferin (MF), a xanthonoid from Mangifera indica, possesses anti-inflammatory, immunomodulatory, and potent antioxidant effects; however, its protective effect against mesenteric ischemia/reperfusion (I/R)-induced liver injury has not been fully clarified. The study was designed to assess the possible mechanism of action of MF against mesenteric I/R model. MAIN METHODS: Male Wister rats were treated with MF (20mg/kg, i.p) or the vehicle for 3 days before I/R, which was induced by clamping the superior mesenteric artery for 30minutes followed by declamping for 60minutes...

OBJECTIVE: Isolated dissection of the mesenteric vessels is rare but increasingly recognized. This study aimed to evaluate patient characteristics, primary treatment, and subsequent outcomes of mesenteric dissection using multi-institutional data. METHODS: All patients at participant hospitals between January 2003 and December 2015 with dissection of the celiac artery (or its branches) or dissection of the superior mesenteric artery (SMA) were included. Patients with an aortic dissection were excluded...

BACKGROUND: Primary volvulus of the small intestine associated with chylous ascites is very rare, with only four reported cases. In this paper, we report a new case of primary volvulus associated with chylous ascites. CASE PRESENTATION: The patient was a 70-year-old man. After experiencing bloating and abdominal pain for several hours, he called an ambulance and underwent an emergency examination at our hospital. Abdominal distension, pressure pain, and rebound tenderness were observed throughout his entire abdomen...

BACKGROUND: Acute mesenteric ischemia is often caused by embolization of the mesenteric arterial circulation. Coherent intestinal injury due to ischemia and following reperfusion get visible on macroscopic and histologic level. In previous studies, application of glycine caused an ameliorated intestinal damage after ischemia-reperfusion in rats. Because we speculated that glycine acted here as a signal molecule, we investigated whether the glycine-receptor agonist β-alanine evokes the same beneficial effect in intestinal ischemia-reperfusion...

BACKGROUND: Nonocclusive mesenteric ischemia can cause intestinal infarction but the diagnosis is challenging. This prospective study evaluated three plasma biomarkers of intestinal infarction after cardiac surgery. MATERIALS AND METHODS: Patients were recruited after cardiac surgery if they required laparotomy (with or without intestinal resection) for suspected nonocclusive mesenteric ischemia. Plasma levels of D-lactate, intestinal fatty acid-binding protein (i-FABP), and smooth muscle actin (SMA) before laparotomy were measured...

Background: Mesenteric ischemia is a challenging diagnosis. Delay in diagnosis can lead to extent bowel necrosis and poor outcomes. Ischemia and reperfusion syndrome plays an important role in this scenario. Aim: To access effects of different post-conditioning cycles on mesenteric ischemia-reperfusion syndrome. Method: Twenty-five rats were assigned into five groups: Sham, used to establish normal parameters; control group, submitted to mesenteric ischemia for 30 min; in groups GP3, GP1 and GP30, ischemia was followed by post-conditioning protocol, which consisted of 1 cycle of 3 min (GP3), 3 cycles of 1 min (GP1) or 6 cycles of 30 s (GP30), respectively...

The antiphospholipid syndrome (APS), either primary or secondary form, is considered an autoimmune disease with presence of at least one clinical and one laboratory abnormalities as defined by The Sydney criteria. Clinical criteria include vascular thrombosis of venous, artery, small vessel in any organ and recurrent pregnancy pathologies. Mesenteric ischemia is a rare and threatening manifestation of APS. We herein report a case of 34-years old pregnant woman referred to our Emergency Room with thoracic and abdominal acute pain...

SUMMARY: Patients with Cushing's syndrome and excess exogenous glucocorticoids have an increased risk for venous thromboembolism, as well as arterial thrombi. The patients are at high risk of thromboembolic events, especially during active disease and even in cases of remission and after surgery in Cushing's syndrome and withdrawal state in glucocorticoid users. We present a case of Cushing's syndrome caused by adrenocorticotropic hormone-secreting lung carcinoid tumor. Our patient developed acute mesenteric ischemia after video-assisted thoracoscopic surgery despite administration of sufficient glucocorticoid and thromboprophylaxis in the perioperative period...

We report a case of inferior mesenteric artery aneurysm after the replacement of the thoracoabdominal aorta for a chronic dissected thoracoabdominal aortic aneurysm in which the celiac artery and superior mesenteric artery were occluded. We performed the resection of the inferior mesenteric artery aneurysm and the revascularization of the superior mesenteric artery, inferior mesenteric artery, and the meandering artery. The patient's postoperative course was uneventful, without bowel ischemia. From the findings of intraoperative flow measurement of the visceral arteries, revascularization of the SMA was judged to be appropriate in this situation...

Inferior mesenteric artery (IMA) aneurysms are a rare entity, attributing to 1% of sphlanic aneurysms, [1] often found incidentally on evaluation for other intra-abdominal pathologies. Similar to other visceral arterial aneurysm, there is an estimated 20-50% risk of potentially fatal rupture and repair is generally recommended. We report two patients with IMA aneurysms, using them as cases to illustrate feasibility of both open and endovascular management options. Patient one is a 69-year-old male with bilateral claudication found to have an asymptomatic 20 mm IMA aneurysm...

Mesenteric vascular insufficiency is a serious medical condition that may lead to bowel infarction, morbidity, and mortality that may approach 50%. Recommended therapy for acute mesenteric ischemia includes aspiration embolectomy, transcatheter thrombolysis, and angioplasty with or without stenting for the treatment of underlying arterial stenosis. Nonocclusive mesenteric ischemia may respond to transarterial infusion of vasodilators such as nitroglycerin, papaverine, glucagon, and prostaglandin E1. Recommended therapy for chronic mesenteric ischemia includes angioplasty with or without stent placement and, if an endovascular approach is not possible, surgical bypass or endarterectomy...

Mesenteric ischemia-reperfusion (I/R)-induced injury targets primarily endothelial and epithelial cells, leading to a cascade of inflammatory events, eventually culminating in life-threatening syndromes. Hitherto, the role of Eph, the largest family of tyrosine kinase receptors, and of their cell-bound ephrin ligands, whose interaction generates a bidirectional signaling, is still debated in I/R injury. The aim of the present work was therefore to investigate the effects produced by unidirectional activation of forward signaling (administration of chimeric protein ephrinA1-Fc), of reverse signaling (EphA2-Fc), or inhibition of both signals (monomeric EphA2 and the protein-protein interaction inhibitor UniPR1331) on the local and systemic inflammatory responses triggered by mesenteric I/R in mice...

Covering and embolizing the celiac artery has been reported to be a relatively safe procedure, owing to the rich collateral pathway between the celiac artery and superior mesenteric artery. A 69-year-old man presented with an aneurysm on the distal descending aorta. The proximity of the aneurysm to the celiac artery origin necessitated covering the artery with a stent graft. Additionally, the celiac trunk was short, increasing the risk for Type II endoleak. The origin of the celiac artery was covered after embolization of the branches of the celiac artery...

BACKGROUND: Hepatic artery thrombosis (HAT) is reported in 4%-15% of orthotopic liver transplants. Risk factors include technical error in the anastomosis, vascular anatomic variation, and high microvascular resistance. The aim of this study was to verify the incidence of HAT, early or late, and possible risk factors. METHODS: This was a retrospective study from January 2007 to December 2012 at the State University of Campinas. Variables analyzed were age, sex, cold and warm ischemia times, underlying disease, presence of hepatocellular carcinoma, Model for End-Stage Liver Disease (MELD) score, arterial anatomic variation in the graft, cytomegalovirus (CMV) infection, rejection, biliary complications, retransplantation rate, and survival...

Major hepatic surgery with inflow occlusion, and liver transplantation, necessitate a period of warm ischemia, and a period of reperfusion leading to ischemia/reperfusion (I/R) injury with myriad negative consequences. Potential I/R injury in marginal organs destined for liver transplantation contributes to the current donor shortage secondary to a decreased organ utilization rate. A significant need exists to explore hepatic I/R injury in order to mediate its impact on graft function in transplantation. Rat liver hilar clamp models are used to investigate the impact of different molecules on hepatic I/R injury...

REVIEW
Srinivas R Rami Reddy, Mitchell S Cappell
PURPOSE OF REVIEW: This study aimed to systematically review small bowel obstruction (SBO), focusing on recent changes in diagnosis/therapy. RECENT FINDINGS: SBO incidence is about 350,000/annum in the USA. Etiologies include adhesions (65%), hernias (10%), neoplasms (5%), Crohn's disease (5%), and other (15%). Bowel dilatation occurs proximal to obstruction primarily from swallowed air and secondarily from intraluminal fluid accumulation. Dilatation increases mural tension, decreases mucosal perfusion, causes bacterial proliferation, and decreases mural tensile strength that increases bowel perforation risks...

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...
