A Rare Case of Ischemia-Reperfusion Injury After Mesenteric Revascularization.

Vasc Endovascular Surg 2019 Apr 14:1538574419839547. Epub 2019 Apr 14.

1 Department of Angiology and Vascular Surgery, Quirónsalud Málaga Hospital, Málaga, Spain.

Endovascular treatment of chronic mesenteric ischemia is currently the treatment of choice, regardless of the number of involved vessels. Unlike other anatomic areas, the hyperperfusion produced by revascularization and the consecutive reperfusion syndrome is only described in cases of acute bowel ischemia, which is usually resolved with traditional surgery. We present a case of severe hyperperfusion syndrome secondary to endovascular correction with stents of a critical ischemia affecting the celiac trunk and superior mesenteric artery. Read More

High-Value Multidetector CT Angiography of the Superior Mesenteric Artery: What Emergency Medicine Physicians and Interventional Radiologists Need to Know.

Radiographics 2019 Mar-Apr;39(2):559-577

From the Divisions of Body CT (N.G., E.K.F., P.T.J.) and Interventional Radiology (R.L.), Russell H. Morgan Department of Radiology and Radiologic Science, Johns Hopkins Hospital, 601 N Caroline St, Room 4223, Baltimore, MD 21287.

The superior mesenteric artery (SMA) provides vital blood supply to the midgut, and an acute abnormality can rapidly precipitate bowel ischemia and infarction and lead to morbidity and mortality. Vascular diseases that acutely compromise the SMA threaten its tributaries and include occlusion, dissection, aneurysm rupture, pseudoaneurysm, vasculitis, and SMA branch hemorrhage into the bowel. Emergency medicine physicians rely on the radiologist to identify SMA abnormalities, to characterize them, and to detail findings that guide the appropriate triage of these patients. Read More

Non-alcoholic steatohepatitis aggravates nitric oxide synthase inhibition-induced arteriosclerosis in SHRSP5/Dmcr rat model.

Int J Exp Pathol 2018 12 24;99(6):282-294. Epub 2019 Jan 24.

Department of Medical Technology, Graduate School of Health Sciences, Okayama University, Okayama, Japan.

Non-alcoholic steatohepatitis (NASH) is linked to increased cardiovascular risk, independent of the broad spectrum of metabolic syndrome risk factors. Stroke-prone (SP) spontaneously hypertensive rats (SHRSP5/Dmcr) fed a high-fat and high-cholesterol (HFC) diet developed hepatic lesions similar to those in human NASH pathology. These rats simultaneously developed lipid deposits in the mesenteric arteries, cardiac fibrosis, endothelial dysfunction and left ventricle (LV) diastolic dysfunction. Read More

Department of Cardiovascular Surgery and Department of Cardiology, Yokohama Sakae Kyosai Hospital, 132, Katsuracho, Sakae-ku Yokohama-shi, Kanagawa 247-8581 Japan.

Background: Endovascular therapy (ET) for chronic mesenteric ischemia (CMI) is a effective treatment to relieve the symptoms, such as postprandial abdominal pain, food fear, and progressive weight loss. CMI is not known to be caused by rare anatomical variation of severe stenosis of the superior mesenteric artery (SMA), with replaced the common hepatic artery to the SMA. The treatment of such a rare anatomical variation using ET technique has not been discribed. Read More

[Vascular causes of clinically unclear acute abdomen].

Radiologe 2019 Feb;59(2):133-138

Klinische Abteilung für Kardiovaskuläre und Interventionelle Radiologie, Universitätsklinik für Radiologie und Nuklearmedizin, Medizinische Universität Wien, Währinger Gürtel 18-20, 1090, Wien, Österreich.

Clinical Issue: Vascular abnormalities are a rare cause of an acute abdomen. They include arterial bleeding and ischemia, the latter being either in the arterial or venous system. The most common cause of an acute ischemic abdomen is acute mesenteric ischemia caused by a thromboembolic occlusion of the superior mesenteric artery, followed by thrombotic occlusion of the portal vein, the mesenteric vein as well as the hepatic veins and the suprahepatic part of the inferior vena cava.

Aberrant splenic artery rising from the superior mesenteric artery: a rare but important anatomical variation.

Surg Radiol Anat 2019 Mar 3;41(3):339-341. Epub 2019 Jan 3.

General, Digestive, and Endocrine Surgery, Nouvel Hôpital Civil, Université de Strasbourg, 1 Place de L'hôpital, 67100, Strasbourg, France.

Aberrant splenic artery originating from the superior mesenteric artery (SMA) is extremely rare and recognition of this anomaly is important in the pre-operative planning of complex surgery such as pancreatic surgery, liver transplantation and vascular surgery. We present the case of an 80-year-old female diagnosed as septic shock due to mesenteric ischemia and obstructive pyelonephritis. Her splenic artery was originating from the SMA and the anomaly was readily appreciated on the pre-operative CT images. Read More

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 01 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.
