Celiac Artery Syndrome After Correction of Kyphoscoliosis.

Spine Deform 2019 01;7(1):176-179

Department of Orthopedics, University Medical Center Utrecht, Heidelberglaan 100 3584 CX, Utrecht, the Netherlands.

Compression of the celiac artery by a tight arcuate ligament of the diaphragm is a rare syndrome that can arise after correction of severe kyphosis. Symptoms include abdominal pain and ileus and liver dysfunctions. These symptoms can be easily attributed to more common causes like the superior mesenteric artery syndrome, and a delay in the diagnosis of celiac artery obstruction may result in severe ischemic disease of the gastrointestinal tract.

Outcomes of antegrade and retrograde open mesenteric bypass for acute mesenteric ischemia.

J Vasc Surg 2019 Jan 29;69(1):129-140. Epub 2018 Jun 29.

Division of Vascular Surgery & Endovascular Therapy, University of Florida, Gainesville, Fla.

Background: Acute mesenteric ischemia (AMI) is a challenging clinical problem associated with significant morbidity and mortality. Few contemporary reports focus specifically on patients undergoing open mesenteric bypass (OMB) or delineate outcome differences based on bypass configuration. This is notable, because there is a subset of patients who are poor candidates for endovascular intervention including those with flush mesenteric vessel occlusion, long segment occlusive disease, and a thrombosed mesenteric stent and/or bypass.

Distal landing zone optimization before endovascular repair of aortic dissection.

J Thorac Cardiovasc Surg 2019 Jan 27;157(1):88-98. Epub 2018 Jul 27.

Department of Surgery, The University of Iowa Roy and Lucille Carver College of Medicine, Iowa City, Iowa.

Background: The general goals of endovascular management in chronic distal thoracic aortic dissection are optimizing the true lumen, maintaining branch patency, and promoting false lumen (FL) thrombosis. Distal seal can be challenging in chronic distal thoracic aortic dissection due to the well-established secondary fenestrations and fibrotic septum. We describe our approach of distal landing zone optimization (DLZO) to enable full-diameter contact of the distal endoprosthesis. Read More

Általános, Ér- és Plasztikai Sebészeti Osztály, Markusovszky Egyetemi Oktatókórház 9700 Szombathely, Markusovszky Lajos u. 5.

Introduction: The incidence of acute mesenteric ischemia (AMI) appears to be increasing due to aging in the population with increasing prevalence of comorbidities. Despite the wide-scale availability of diagnostic technologies, the timely detection and correct treatment are not ensured. This is due to the fact that the required CT angiography is not immediately performed and that vascular surgical reconstruction can be performed within the short ischemic tolerance window of the bowels amounting 4-6 hours.

Hydrogen Sulfide Donor GYY4137 Acts Through Endothelial Nitric Oxide to Protect Intestine in Murine Models of Necrotizing Enterocolitis and Intestinal Ischemia.

J Surg Res 2019 Feb 23;234:294-302. Epub 2018 Oct 23.

Department of Surgery, Section of Pediatric Surgery, Riley Hospital for Children at Indiana University Health, Indianapolis, Indiana; Department of Surgery, Indiana University School of Medicine, Indianapolis, Indiana. Electronic address:

Background: Necrotizing enterocolitis (NEC) in premature infants is often a devastating surgical condition with poor outcomes. GYY4137 is a long-acting donor of hydrogen sulfide, a gasotransmitter that is protective against intestinal injury in experimental NEC, likely through protection against injury secondary to ischemia. We hypothesized that administration of GYY4137 would improve mesenteric perfusion, reduce intestinal injury, and reduce inflammatory responses in experimental NEC and ischemia-reperfusion injury, and that these benefits would be mediated through endothelial nitric oxide synthase-dependent pathways.

Gamma-Aminobutyric Acid (GABA) Attenuates Ischemia Reperfusion-Induced Alterations in Intestinal Immunity.

Biol Pharm Bull 2018 ;41(12):1874-1878

Laboratory of Clinical Pharmaceutics & Therapeutics, Division of Pharmasciences, Faculty of Pharmaceutical Sciences, Hokkaido University.

The aims of this study were to determine the effects of gamma-aminobutyric acid (GABA) on immunoglobulin A (IgA) secretion from Peyer's patch (PP) cells; to assess rat alpha-defensin-5 (RD-5) expression in the rat small intestine; and to determine the effect of GABA on intestinal ischemia reperfusion (I/R) injury-induced intestinal innate immunity. We found that GABA caused an increase in IgA secretion in the presence and absence of lipopolysaccharide (LPS). Moreover, GABA also significantly increased the mRNA levels of RD-5 and superoxide dismutase (Sod) 1, 3. Read More

Air Embolism into Superior Mesenteric Artery Following Replacement of Ascending Aorta for Aortic Dissection - A Rare and Fatal Case.

J Belg Soc Radiol 2018 Oct 18;102(1):68. Epub 2018 Oct 18.

Department of Surgery, First Faculty of Medicine, Charles University in Prague, CZ.

We report an unusual case of fatal air embolism into the superior mesenteric artery in a patient, who underwent replacement of the ascending aorta for aortic dissection type A. CT performed twice on the first postoperative day showed abundant air in the superior mesenteric artery and its branches (but not in the portal-venous system) indicating air embolism with no signs of bowel necrosis. On the second postoperative day, the patient underwent extensive bowel resection due to bowel ischemia and died on the third postoperative day on MODS/SIRS. Read More

Potentiation of serotonin signaling protects against intestinal ischemia and reperfusion injury in mice.

Neurogastroenterol Motil 2018 Nov 4:e13498. Epub 2018 Nov 4.

Department of Surgery, Yale University School of Medicine, New Haven, Connecticut.

Background: Knock-out of serotonin re-uptake transporters (SERT) or use of selective serotonin re-uptake inhibitors (SSRIs) potentiates enteric serotonin (5-HT) signaling and stimulates enterocyte proliferation. We hypothesized that increased serotonin signaling would mitigate epithelial injury from intestinal ischemia and reperfusion (I/R).

Methods: Mice lacking SERT (SERTKO mice) and wild-type littermates (WTLM) were subjected to intestinal ischemia by superior mesenteric artery (SMA) occlusion. Read More
