Buerger's disease is a type of vasculitis that predominantly affects small to medium arteries and the veins of the upper and lower extremities. Intestinal vessels are rarely involved. This is a case report of a 38-year-old male, smoker, with known Buerger's disease who was found to have ischemic colitis of the sigmoid colon on biopsy and inferior mesenteric artery occlusion on computed tomography (CT) angiography.

Intestinal ischemia/reperfusion (I/R) injury often causes inflammatory responses and coagulation disorders, which is further promoting the deterioration of the disease. Hydrogen has anti-inflammatory, antioxidative, and antiapoptotic properties against various diseases. However, the effect of hydrogen on coagulation dysfunction after intestinal I/R and the underlying mechanism remains unclear. Read More

Acute mesenteric ischemia (AMI) is caused by an abrupt cessation of blood flow to the small intestine. Reperfusion is the return of blood flow to the ischemic bowel. Intestinal ischemia/reperfusion (I/R) leads to the formation of reactive oxygen species, local inflammatory response, and may lead to the patient's death. Read More

Background: The Pringle maneuver [portal triad obstruction(PTO)] provides huge disturbances during ischemia and even more thereafter in reperfusion. Contrarily, a possible solution may be stable gastric pentadecapeptide BPC 157, with already documented beneficial effects in ischemia/reperfusion conditions. Recently, BPC 157, as a cytoprotective agent, successfully resolved vessel occlusions in rats (ischemic colitis; deep vein thrombosis, superior anterior pancreaticoduodenal vein; bile duct cirrhosis) through rapid collateral vessel recruitment to circumvent vessel occlusion.

The present study was designed to investigate the role of amylin, H2S, and connexin 43 in vascular dysfunction and enhanced ischemia-reperfusion (I/R)-induced myocardial injury in diabetic rats. A single dose of streptozotocin (65 mg/kg) was employed to induce diabetes mellitus. After 8 weeks, there was a significant decrease in the plasma levels of amylin, an increase in I/R injury to isolated hearts (increase in CK-MB and cardiac troponin release) on the Langendorff apparatus.

Background: En bloc celiac axis resection (CAR) for pancreatic cancer is considered increasingly after modern neoadjuvant chemotherapy (NAC). Appleby and distal pancreatectomy with CAR are anatomically inaccurate terms, as tumors can extend beyond celiac axis proper, requiring concurrent resection of the proper hepatic artery and/or superior mesenteric artery.

Study Design: A 3-level classification for CAR (class 1, 2, or 3) was developed after retrospective review of an arterial resection database describing anatomical variants that dictate pancreatectomy-type, formal arterial revascularization, and gastric preservation. Read More

New Findings: What is the central question of this study? What are the effects of a 2 week period of severe food restriction on vascular reactivity of resistance arteries and on cardiac structure and function? What is the main finding and its importance? This study showed, for the first time, that a 2 week period of severe food restriction in adult male Fischer rats caused endothelial dysfunction in mesenteric arteries and increased the susceptibility to ischaemia-reperfusion-induced arrhythmias and cardiac pathology. Our findings might have ramifications for cardiovascular risk in people who experience periods of inadequate caloric intake.

Abstract: Severe food restriction (sFR) is a common dieting strategy for rapid weight loss. Read More

Chronic mesenteric ischaemia is a severe and incapacitating disease, causing complaints of post-prandial pain, fear of eating and weight loss. Even though chronic mesenteric ischaemia may progress to acute mesenteric ischaemia, chronic mesenteric ischaemia remains an underappreciated and undertreated disease entity. Probable explanations are the lack of knowledge and awareness among physicians and the lack of a gold standard diagnostic test. Read More

Background: Some studies suggest that celiac artery coverage during elective endovascular thoracoabdominal aortic aneurysm (TAAA) repair is safe given sufficient collateralization of visceral organ perfusion from the superior mesenteric artery. However, there is concern that celiac artery coverage may lead to increased risk of foregut or spinal cord ischemia with an attendant increased risk of mortality. We sought to investigate rates of bowel ischemia, spinal cord ischemia, and 30-day mortality associated with celiac artery coverage during TEVAR and complex EVAR. Read More
