Introduction: Superior mesenteric artery (SMA) syndrome is a rare and unusual acquired cause of functional duodenal obstruction whose diagnosis can be easily missed without knowledge of this condition. Case Presentation: We report a case of a 27-year-old female, presenting with post-prandial vomiting, early satiety, bloatedness and weight loss for about 10 months. Vital signs were stable. She was grossly underweight with a BMI of 11.72 kg/m2 (height=1.6m, weight=30kg). Physical examination was unremarkable. Gastrointestinal series revealed a narrowing in the third portion of the duodenum likely secondary to extrinsic compression. Contrast-enhanced CT scan of the whole abdomen was performed with 3D reconstruction. There were no definite signs of gastrointestinal obstruction. However, a narrow/acute aorto-mesenteric angle of 13 degrees compressing the third part of the duodenum was noted. Superior mesenteric syndrome was considered, prompting further work-up. Primary hyperthyroidism was the root cause of the patient’s weight loss that lead to this condition. Patient was given nutritional support, parenterally and enterally. She was discharged improved after oral feeding was tolerated and patient started to gain weight. Discussion: Superior mesenteric artery (SMA) syndrome is an uncommon medical condition brought about by a decrease in the aortomesenteric angle from the usual 45o to less than 15o resulting in vascular compression of the third part of the duodenum leading to gastrointestinal obstruction. A high index of suspicion is needed to prevent the diagnosis from being missed which may in turn lead to unnecessary testing and treatment. If recognized early, the condition may be managed conservatively. Surgical management is only required when conservative methods fail. Conclusion Early recognition and a thorough evaluation is therefore imperative so conservative measures can be maximized at the outset.
Superior Mesenteric Artery Syndrome

Bariatric surgery is the most effective and durable treatment for morbidly obese patients. However, there are remained unsolved problems with various types of complications. Superior mesenteric artery syndrome is a rarely known condition occurred following bariatric surgery. We experienced 54-year-old female patient diagnosed with superior mesenteric artery syndrome 5 year later after laparoscopic adjustable gastric banding. Because symptoms have not improved with conservative care, laparoscopic duodenojejunal bypass was successfully performed for this patient.

Superior mesenteric artery syndrome (SMAS) is a rare clinical disease. SMAS is defined as the entrapment of the third portion of the duodenum by the aorta and the superior mesenteric artery. A 14-year-old male patient was admitted to the local hospital for an emergency appendectomy under general anesthesia. In the process of inducing general anesthesia, massive pulmonary aspiration of gastric contents and bile juice occurred by accident. After surgery, he was transferred to our hospital due to severe ARDS. The gastroduodenoscopy observations, CT, and clinical symptoms, were indicative of SMAS. Surgery was considered because medical conservative treatment of SMAS was ineffective. SMAS was confirmed on the surgical fields. We report our experience with a review of the relevant literature because this condition can be associated with serious complications during general anesthesia.

The most common cause of small bowel obstruction is postoperative adhesion, and besides a hernia, metastatic or primary cancer and small bowel tumors are possible causes. Superior mesenteric artery (SMA) syndrome is a rare cause of upper gastrointestinal obstruction and is associated with debilitating conditions with marked weight loss. SMA syndrome results from the compression of the third part of the duodenum due to the narrowing of the aortomesenteric angle. We report a 28-year-old woman with SMA syndrome after acute gastroenteritis. Her stomach was severely dilated due to the duodenal obstruction and computed tomography showed the compression of the third portion of the duodenum by SMA. She was conservatively cared for and thus favorably improved.

Superior mesenteric artery (SMA) syndrome is a symptom complex resulting from compression of third portion of duodenum by the root of the small bowel mesentery at the level of the SMA. This syndrome can occur as an acute illness but more commonly it appears as chronic condition. Identification of this syndrome can be a diagnostic dilemma and it is frequently made by exclusion. In our patient, rapid weight loss, nausea and bile stained vomiting were present. Ultrasound and MR-angiography were performed for measuring the angle and the distance between the SMA and the aorta. We confirmed the diagnosis via the reduced aorto-mesenteric angle and distance and the patient was then treated by laparoscopic surgery. After lysis of the ligament of Treitz, the patient's symptom were improved. This syndrome must be considered as one of the causes of upper gastrointestinal obstruction.

Superior mesenteric artery syndrome (SMAS) is a rare disease and is seldom seen in patients with abdominal aortic aneurysms. We experienced a SMAS as a result of an enlarged abdominal aortic aneurysm in a 52 year-old female patient who had undergone renal transplant in the right iliac position 8 years previously. The abdominal aortic aneurysm was successfully resected without an extracorporeal bypass during crossclamping, and postoperatively the patient's symptoms were improved and her renal function was well preserved.

Superior mesenteric artery (SMA) syndrome is a rare disorder, characterized by a decreased aortomesenteric angle that causes a duodenal obstruction. Various medical and psychiatric conditions may result in the initial rapid weight loss that causes narrowing of the aortomesenteric angle. Isolated dissection of the superior mesenteric artery (DSMA) is an uncommon cause of acute mesenteric ischemia. Several literature reports suggest that medical treatment in combination with close observation is reasonable in uncomplicated dissection with stable hemodynamic status. Recently, as several reports describe, rapid revascularization by percutaneous angioplasty and endovascular stent insertion can prevent bowel ischemia that progresses to irreversible bowel necrosis. However, the stability of endovascular stents at the DSMA has not been confirmed, because its use is reasonably infrequent. Here, we report a case of SMA syndrome, as a complication of endovascular stent placement at the DSMA.
