INTRODUCTION Nausea and vomiting in an adolescent, though common presenting symptoms, often pose a diagnostic and therapeutic challenge to the physician. When the diagnosis involves both medical and psychiatric components, management can be complex, especially in the current healthcare system in the United States. To the best of our knowledge, there have been no previous publications detailing ...

CONTEXT Superior mesenteric artery syndrome is a life- threatening upper gastrointestinal disorder due to compression of duodenum as it poses a difficult diagnostic dilemma. Third part of duodenum is in fixed compartment bounded anteriorly by the root of mesentery and superior mesentery artery and posteriorly by the aorta and lumbar spine. On barium contrast study and abdominal computerized tom...

Superior mesenteric artery syndrome (SMAS) has been proposed as a rare cause of proximal bowel obstruction resulting from compression of the third portion of the duodenum secondary to narrowing of the space between the aorta and superior mesenteric artery. The main risk factors associated with SMAS are significant weight loss, corrective spinal surgery and congenital or acquired anatomic abnorm...

The superior mesenteric artery extends anteriorly and inferiorly off the aorta at the level of the first lumbar vertebrae. The duodenal sweep and left renal vein are located in the aorto-mesenteric angle space. A decrease from the normal angle may compress these two structures. The case presented here discusses a unique patient with significant compression of the third portion of the duodenum a...

Abdominal tuberculosis is the sixth most common site of extra pulmonary tuberculosis. 1 TB may affect any portion of the GI tract however, in 85% of cases ileocecal region is affected whereas gastroduodenal region is involve only 0.3-2.3% of TB cases of abdominal TB. 2 When gastroduodenal TB is seen without any other lesion of TB in body it is known as primary gastroduodenal TB, which is very r...

Nutcracker syndrome is a rare condition that refers to compression of left renal vein (LRV) between abdominal aorta and superior mesenteric artery. The most common location of compression is between the superior mesenteric artery (SMA; Pic. 1) and abdominal aorta. The name derives from the fact that, in the sagittal plane and/or transverse plane, the SMA and aorta (with some imagination) appear...

Weight loss resulting from the hypermetabolic response to burn injury is not unusual and is often unavoidable. The loss of retroperitoneal fat has been postulated as a major factor in the cause of the uncommon complication of superior mesenteric artery syndrome. This syndrome is frequently treated nonoperatively with aggressive nutrition support. Nasojejunal feeding past the point of obstructio...

Superior mesenteric artery syndrome is a life-threatening rare acquired upper gastrointestinal disorder due to mechanical compression of third part of duodenum by the acute angulation of Superior mesenteric artery, leading to obstruction. Acute loss of intervening mesenteric fat as a result of a variety of debilitating conditions is believed to be the etiologic factor causing the reduced aortom...

Superior mesenteric artery syndrome is a condition caused by the compression of the third part of the duodenum between the superior mesenteric artery and the aorta. We present the clinical case of a patient, a female, 18 years old, with history of two days' evolution characterized by postprandial epigastric colic, accompanied by nausea and intractable vomiting. Applied conservative management w...

OBJECTIVES The differential diagnosis of intestinal obstruction includes mechanical obstruction, obstruction secondary to systemic disease, and idiopathic intestinal pseudo-obstruction. The causes of these are extensive; however, the majority of cases involve a mechanical cause. Superior mesenteric artery syndrome (SMAS) is a rare and controversial form of mechanical obstruction with just over ...
