INTRODUCTION: The management of patients with abdominal aortic injury (AAI) remains challenging. Open repair of AAI is still the standard of care, however, open repair is associated with high mortality. In past few years endovascular surgery has evolved as a less invasive alternative to open surgery in emergency settings. The objective of this study was to compare outcomes after open repair vs. endovascular repair of AAI in poly-trauma patients. METHODS: The National Trauma Data Bank, from 2008-2012, was queried to identify trauma patients undergoing open and endovascular repair of AAI using ICD-9 codes...

Hepatic portal venous gas (HPVG) is a rare radiological sign that usually signifies an acute intra-abdominal process, most commonly bowel ischemia and sepsis. Few reports described an association with underlying gastric pathologies. We report a 60-year-old patient who presented with melena and chills and was discovered to have a gastric ulcer that appeared to have penetrated into a mesenteric varix. This, in turn, likely caused development of HPVG associated with fungemia. Treatment with a proton pump inhibitor and bowel rest was sufficient to resolve symptoms and the HPVG...

BACKGROUND: The impact of preoperative anemia and postoperative hemoglobin (Hb) drop on the incidence of acute kidney injury (AKI) after thoracic endovascular aortic repair (TEVAR) for type B acute aortic syndromes (AAS) as well as their prognostic value is unknown. METHODS: This retrospective study included 144 patients with type B AAS undergoing TEVAR at our center. Preoperative anemia was classified as no/mild (Hb ≥ 12.0 g/dL in men; ≥11.3 g/dL in women), moderate (Hb 10...

INTRODUCTION: Persistent or chronic intestinal ischemic injury (i3) can lead to severe malnutrition and acute mesenteric ischemia. Although recommended, revascularization of splanchnic arteries is sometimes unrealizable. MATERIAL AND METHODS: We report a case series of iloprost use in consecutive stable patients with persistent i3 unsuitable for revascularization followed in a tertiary care center. The feasibility of revascularization was discussed and ruled out by a multidisciplinary team, and informed consent was obtained prior to consideration of a vasoactive therapy...

BACKGROUND: Early diagnosis of acute mesenteric ischemia (AMI) based on clinical judgment has been proved to be too difficult. Therefore, it is important for identifying clinical parameters that can differentiate AMI from other acute abdomen upon presentation. METHODS: We analyzed a database of 106 consecutive patients admitted to the emergency ward for suspected AMI in whom diagnosis of AMI was confirmed by laparotomy, CT angiography or mesenteric angiography. The patients' demographics, previous history, clinical signs, results of laboratory investigations and ultrasonography were collected...

AIM: The electroneutral Na(+) ,HCO3(-) -cotransporter NBCn1 and Na(+) /H(+) -exchanger NHE1 regulate acid-base balance in vascular smooth muscle cells (VSMCs) and modify artery function and structure. Pathological conditions-notably ischemia-can dramatically perturb intracellular (i) and extracellular (o) pH and [Na(+) ]. We examined effects of low [Na(+) ]o and pHo on NBCn1 and NHE1 activity in VSMCs of small arteries. METHODS: We measured pHi by 2',7'-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein-based fluorescence microscopy of mouse mesenteric arteries and induced intracellular acidification by NH4(+) -prepulse technique...

Bioimpedance has been used to investigate changes in electrical parameters during ischemia in various tissues. The small intestine is a multi-layered structure, with several distinct tissue types, and ischemia related changes occur at different times in the different intestinal layers. When investigating how the electrical properties in the small intestine is affected by ischemia, some researchers have used ex-vivo models while others have used in-vivo models. In this study, we compare ischemic time development of electrical parameters in ischemic in-vivo versus ex-vivo small intestine...

Hepatic portal venous gas (HPVG) is a rare ominous radiological sign usually indicative of mesenteric ischemia. Increased detection of HPVG has been associated with a growing number of non-ischemic causes. A 64-year-old gentleman following radical cystectomy and neobladder formation developed clinical signs suggestive of bowel obstruction. HPVG was demonstrated on abdominal imaging. Urgent laparotomy revealed no evidence of ischemia. We hypothesize an obstructed neobladder permitted gas to enter the mesenteric circulation...

Small bowel intussusception (SBI) in pediatric patients resolves spontaneously in the majority of cases. Pathologic small bowel intussusception with a lead point is rare in children. Ultrasound (US) is the preferred initial imaging study for the diagnosis of intussusception. We report a case of long-segment SBI and secondary bowel obstruction caused by a large hamartomatous polyp. This case emphasizes unique, atypical ultrasound findings that may be encountered in small bowel intussusception, with correlative radiographic, CT (computed tomography) and intra-operative findings...

BACKGROUND: Chronic mesenteric ischemia (CMI) is a rare disease. Open treatment (OT) remains a valuable treatment option. We analyzed patient outcomes after OT and investigated health-related quality of life (HRQoL). METHODS: Data were analyzed retrospectively. The investigation period was from January 1, 2001, to December 31, 2014. We investigated mortality and patency rates using Kaplan-Meier analysis. HRQoL was measured using a 36-item health survey. Various statistical methods were employed...

Ischemia/reperfusion (I/R) injury of the small intestine caused by occlusion of the superior mesenteric artery affects the intestinal tissue as well as components of the blood circulatory system from the microvasculature to mesenteric vessels. The aim of this work was to study the correlation between the dynamics of destruction development in the intestinal tissue, microvasculature, and mesenteric vessels in I/R of the small intestine. The microvasculature was analyzed by whole-organ continuous monitoring of the intestinal mucosal blood perfusion by laser Doppler flowmetry during the entire I/R...

OBJECTIVES: To identify predictive factors for irreversible transmural intestinal necrosis (ITIN) in acute mesenteric ischemia (AMI) and establish a risk score for ITIN. METHODS: This single-center prospective cohort study was performed between 2009 and 2015 in patients with AMI. The primary outcome was the occurrence of ITIN, confirmed by specimen analysis in patients who underwent surgery. Patients who recovered from AMI with no need for intestinal resection were considered not to have ITIN...

Purpose. Early recognition of acute mesenteric ischemia (AMI) can be challenging. Extensive bowel necrosis secondary to AMI is associated with high rates of mortality. The aim of this study was to investigate the association between preoperative serum lactate level and the extent of bowel ischemia in patients with AMI. Methods. Data of patients with abdominal pain and elevated serum lactate undergoing emergency laparotomy for suspected AMI within 24 hours of presentation was retrospectively abstracted. The length of the ischemic bowel segment was compared with the preoperative serum lactate level...

OBJECTIVE: Although extensive collateral arterial circulation will prevent ischemia in most patients with stenosis of a single mesenteric artery, mesenteric ischemia may occur in these patients, for example, in patients with celiac artery compression syndrome (CACS). Variation in the extent of collateral circulation may explain the difference in clinical symptoms and variability in response to therapy; however, evidence is lacking. The objective of the study was to classify the presence of mesenteric arterial collateral circulation in patients with CACS and to evaluate the relation with clinical improvement after treatment...
