Nutcracker syndrome (NCS) is caused by compression of left renal vein (LRV), usually between the aorta and the superior mesenteric artery (SMA). This can lead to obstruction of flow into the inferior vena cava and secondary left renal venous hypertension. Despite potential serious consequences, diagnosing NCS is often challenging, circuitous and commonly delayed. We report an extremely unique case of NCS. A 34-year-old woman presented with left flank pain and discomfort. On investigation, it was found that high pressure in the LRV, due to compression by the SMA, had led to a large venous aneurysm that had caused pelviureteric junction obstruction and hydronephrosis...

BACKGROUND: There has been a lengthy discussion on the extent of lymphatic resection for right-sided colon cancer and the central borders of the mesentery that are not yet defined. The objectives of this study are to define minimal clearances for adequate lymphatic resection in regard to colic artery origins and the superior mesenteric artery (SMA) and vein (SMV) relevant to right colectomy. METHODS: Central mesenteric lymph vessels, nodes, and blood vessels were dissected in 16 cadavers...

Superior mesenteric artery syndrome (SMAS) is a relatively rare disease that involves bowel obstruction symptoms, such as vomiting and gastric distension, owing to the compression of the third portion of the duodenum from the front by the superior mesenteric artery (SMA) and from the rear by the abdominal aorta and the spine. SMAS is diagnosed on the basis of an upper gastrointestinal examination series indicating the obstruction of the third portion of the duodenum or a computed tomography scan indicating the narrowing of the branch angle between the aorta and the SMA (i...

A 67-year-old man visited our hospital for jaundice. Abdominal dynamic CT showed the hypovascular tumor at the head of the pancreas that surrounded superior mesenteric artery(SMA)at an angle of 220 degree. No metastasis in lymph nodes and other organs was observed. We diagnosed the tumor unresectable locally advanced(UR-LA)pancreatic cancer. Chemotherapy was administered with gemcitabine and nab-paclitaxel(GEM+nab-PTX)and achieved partial response. Regression in size and in range around SMA to an angle of 150 was observed...

Critical illness is accompanied by hypothalamic-pituitary-adrenal axis activation, but adrenal insufficiency characterized by inadequate glucocorticoid synthesis is common in critically ill cirrhotic patients, the 'hepato-adrenal syndrome'. Adrenal cortex also synthesizes androgen (dehydroepiandrosterone, DHEA). DHEA maintains microcirculation by enhancing vascular endothelial nitric oxide synthase (eNOS) activity. In critical patients of other disease entities, a shift of adrenal steroidogenesis away from androgens towards glucocorticoid has been noted, arousing interests in androgen replacement in critical settings...

Superior mesenteric artery (SMA) syndrome is a rare cause of small bowel obstruction (SBO) resulting from compression of the duodenum by the SMA. Patients at risk of developing SMA syndrome include those who have experienced rapid weight loss from chronic illnesses, malignancy, bariatric surgery, eating disorders, burns, trauma, or substance abuse. We present the case of a 54-year-old cachectic female patient who presented with sudden onset nausea, vomiting, and severe epigastric pain. Imaging studies revealed distention of the stomach and proximal portion of the duodenum with abrupt narrowing of the third part of the duodenum consistent with SMA syndrome...

BACKGROUND: R status represents an important prognostic factors in periampullary cancers. Thus, it is useful to verify if it can be influenced by different techniques of margination. METHODS: Single-centre, randomised clinical trial of patients affected by periampullary cancer who underwent pancreaticoduodenectomies which included two different types of margination: arm A (multicolour inking) and arm B (monocolour inking). The primary endpoint was the overall R1 resection rate and its difference between the two arms...

BACKGROUND AND PURPOSE: Mesopancreas dissection with central vascular ligation and the superior mesenteric artery (SMA)-first approach represent the cornerstone of current principles for radical resection for pancreatic head cancer. The surgeon dissecting around the SMV and SMA should be aware regarding the anatomical variants in this area. The aims of this systematic review and meta-analysis are to detail the surgical anatomy of the superior mesenteric vessels and to propose a standardized terminology with impact in pancreatic cancer surgery...

A 78 year-old man was diagnosed as a pancreatic cancer in department of gastroenterology in our hospital. Enhanced computed tomography demonstrated an aberrant right hepatic artery(ARHA)arising from superior mesenteric artery(SMA). We conducted sub-stomach preserving pancreaticoduodenectomy(SSPPD- II A-1). As the preoperative diagnosis, right hepatic artery(RHA)was arising from SMA and running through the tumor, and we resected the ARHA with the tumor and reconstructed RHA to gastroduodenal artery(GDA). Pathological diagnosis was non invasive tumor with neither lymph node metastasis nor invasion of the vasculature...

The aim of this paper is to report a salvage treatment for malpositioned stent graft due to mislabeled product during thoracic endovascular aortic repair (TEVAR) in descending thoracic aneurysm (DTA). A 78-year-old male presented with 6.7×4.1 cm sized saccular DTA and 7.1×7.3 cm sized abdominal aortic aneurysm (AAA). DTA was initially treated by TEVAR and 2 months later AAA was treated by open aortic repair. Unfortunately, although the stent graft was correctly labeled for DTA, the actual size of product wrapped in a box was different contrary to our expectations...

BACKGROUND: The aim of this study was to investigate the effects of melatonin on intestinal anastomosis after intestinal ischemia/ reperfusion injury (IRI). METHODS: Thirty Wistar albino rats of both sexes were divided into 3 groups: sham, control, and treatment. IRI was performed by clamping the superior mesenteric artery (SMA) for 30 minutes, followed by reperfusion. The sham rats received only manipulation of the SMA. Melatonin (10 mg/kg) was administered to the treatment group, and the control group was given a vehicle injection...

An interaction between the intestine and cardiovascular disease has been suggested. We thought to clarify the association between intestinal conditions and clinical outcomes in patients with heart failure (HF). Hemodynamic parameters in intestinal vessels [superior mesenteric artery (SMA), inferior mesenteric artery (IMA), and portal vein (PV)] and average colon wall thickness (aCWT) from the ascending colon to sigmoid colon were evaluated in 224 hospitalized HF patients. Echocardiographic parameters and composite event rates (all-cause mortality, readmission for HF deterioration, major ventricular arrhythmias) were also examined...

Superior mesenteric artery (SMA) syndrome often occurs in the setting of rapid weight loss and scoliosis corrective spinal surgery. A reduction of fat around the third part of the duodenum can predispose the duodenum to compression and obstruction by the SMA as it emerges from the abdominal aorta. In this report, we describe this underdiagnosed condition in a previously healthy young female presenting with progressive post-prandial emesis, non-specific abdominal pain, and weight loss. A critical review of this disease process is explored to highlight pathology, imaging characteristics, and essential alternative diagnostic considerations...

BACKGROUND: Nonocclusive mesenteric ischemia (NOMI) is a mesenteric arterial spasm and intestinal ischemia. This disease is a highly lethal disease because diagnosis and decision of appropriate treatments are often difficult. Operations cannot resolve the spasms and may worsen the situation. However, the safety and effectiveness of catheterization for NOMI with aortic dissection (AD) have not yet been elucidated. Here, we report a successful case of early diagnosis and treatment of NOMI with type B AD involving the superior mesenteric artery (SMA) using the intra-arterial infusion of a vasodilator via the SMA...

BACKGROUND AND OBJECTIVES: Without prompt superior mesenteric artery (SMA) revascularization, acute mesenteric ischemia (AMI) frequently leads to death or short bowel syndrome (SBS). In SBS patients, persistent or chronic intestinal ischemia (PII) of the remnant bowel can lead to recurrences of AMI. Since SMA revascularization is sometimes unfeasible, celiac artery (CA) revascularization may improve blood supply to the remnant bowel. The aim of this study was to describe and to assess our experience of the CA revascularization in case of SMA occlusion unsuitable for revascularization in the setting of PII in SBS patients...

BACKGROUND Celiacomesenteric trunk (CMT) is a very rare anatomic finding in which the celiac artery and the superior mesenteric artery (SMA) originate from the abdominal aorta through a common trunk. Clinical associations with CMT include arterial aneurysm, thrombosis, and celiac artery compression. However, an association between CMT and abdominal venous congestion caused by left renal vein compression, or 'nutcracker phenomenon,' has not been previously reported.

Background: Visceral arterial pseudoaneurysms (VAPAs) are rare vascular entities with serious consequences. Traditionally, they are associated with trauma, infection, and inflammatory disease, or they can arise as a post-operative complication. Report: An 87 year old man presented with abdominal pain and was found to have a spontaneous VAPA on a computed tomography angiogram. Serial imaging 4 months previously had demonstrated no aneurysm. Between scans, warfarin was changed to apixaban for aortic valve replacement, but he had no other changes to any other medications...
