BACKGROUND: Acute mesenteric ischemia (AMI) is a rare but severe complication after cardiac surgery. However, AMI is likely to be more frequent in the subgroup of patients presenting with multiple organ failure after a cardiac surgery. The primary objective of this study was to identify AMI risk factors among patients requiring intensive care unit (ICU) admission after cardiac surgery. METHODS: Retrospective observational study of all the patients requiring admission to two ICUs in a large university hospital after a cardiac surgery procedure...

PURPOSE: We report a combined technique consisting of thrombectomy and thromboaspiration for the treatment of acute embolic occlusion of the superior mesenteric artery (SMA) at the origin. CASE: A 90-year-old female with chronic atrial fibrillation had a sudden onset of abdominal pain and hematochezia due to acute embolic occlusion at the origin of the SMA. Computed tomographic findings showed reversible bowel wall ischemia. We performed mechanical thrombectomy using the Solitaire FR revascularization device, a self-expanding and fully retrievable stent-based thrombectomy system for acute intracranial large artery occlusion, combined with manual aspiration through a 6F guiding sheath placed at the SMA origin via a right brachial approach...

A number of nontraumatic acute abdomen can result in peritonitis leading to sepsis. In emergent conditions, various procedures like segmentary colectomy and/or subtotal colectomy with anastomosis, Hartmann's procedure, transverse colectomy, and/or expandable metallic stent (SEMS) placement can be performed, considering the status of the patient and the facilitaties of the institution. In our study, we examined the cases diagnosed as acute abdomen without the history of trauma, which had lead to a procedure requiring colostomy...

Intestinal ischemia reperfusion (IR) injury is a critical problem, which can cause intestinal injury locally and acute lung injury (ALI) distally by inflammatory responses and oxidative stress. Toll-like receptor 4 (TLR4) is involved in innate immune and inflammatory responses. This study was to determine whether TLR4 mutant can attenuate intestinal and lung injuries after intestinal IR. Wild type (WT) and TLR4 mutant mice were submitted to intestinal IR by occluding the superior mesenteric artery. Histological assessment of the intestine and the lung were conducted by HE staining...

Chronic Mesenteric Ischemia (CMI) presenting as acute abdomen can be treated percutaneously. An endovascular intervention has surpassed surgical revascularization over the past decade due to its lesser perioperative complication rate. Trans-femoral approach of revascularising is limited by its difficulty in coaxial alignment of the guiding catheter and hence, brachial artery and recently the radial approach have been utilized for mesenteric artery revascularisation for over a decade. Here by we report a case of chronic mesenteric ischemia having total occlusion of two and 70% occlusion of one of the three mesenteric vessels...

The mammalian intestinal mucosa exhibits a spectrum of responses after acute injury and repairs itself rapidly to restore the epithelial integrity. The RNA-binding protein HuR regulates the stability and translation of target mRNAs and is involved in many aspects of gut epithelium homeostasis, but its exact role in the regulation of mucosal repair after injury remains unknown. Here we show that HuR is essential for early intestinal epithelial restitution by increasing the expression of cell division control protein 42 (Cdc42) at the posttranscriptional level...

Vascular complications are an important adverse event that can be associated with spinal reconstructive surgery. Direct injury of vessels, or indirect traction or compression of vessels, can cause both arterial and venous injury. Indirect compression of the mesenteric vessels is a well-recognized complication of bracing and surgical care of children with spinal deformity (superior mesenteric artery syndrome), but the complication is not common or well recognized in the adult population with spinal deformity...

Human immunodeficiency virus (HIV)-associated vasculitis is a rare secondary systemic vasculitis involving medium and small arteries. We report a 42-year-old man with uncontrolled HIV infection presenting with long-lasting abdominal pain. An abdominal CT angiography revealed multiple microaneurysms and stenoses in intrarenal arteries, with involvement of mesenteric and hepatic arteries. HIV-associated vasculitis was diagnosed and glucocorticoids and raltegravir-based antiretroviral therapy were administered with good initial clinical and virological response...

The use of low-level laser for lung inflammation treatment has been evidenced in animal studies as well as clinical trials. The laser action mechanism seems to involve downregulation of neutrophil chemoattractants and transcription factors. Innate immune responses against microorganisms may be mediated by toll-like receptors (TLR). Intestinal ischemia and reperfusion (i-I/R) lead to bacterial product translocation, such as endotoxin, which consequently activates TLRs leading to intestinal and lung inflammation after gut trauma...

BACKGROUND: Non-occlusive mesenteric ischemia (NOMI) is a common complication and accounts for a major cause of death in critically ill patients. The diagnosis of NOMI with respect to the eventual indications for surgical treatment is challenging. We addressed the performance of the diagnostic strategy of NOMI in the intensive care unit, with emphasis on contrast-enhanced abdominal CT-scan. METHODS: This was a retrospective monocenter study. Patients with clinically suspected acute mesenteric ischemia were included if a comprehensive diagnostic workup was carried out including surgical and/or endoscopic digestive explorations...
