Superior Mesenteric Artery Syndrome Diagnosed with Linear Endoscopic Ultrasound (with Video) in a Patient with Normal Body Mass Index

Abstract

Superior mesenteric artery (SMA) syndrome is an uncommon disease that results from SMA compression of the third portion of the duodenum. Patients with SMA syndrome present with upper gastrointestinal symptoms, such as nausea, vomiting, and abdominal pain. The diagnosis is usually made from an upper barium study or computed tomography. Typically, SMA syndrome is caused by a decreased aortomesenteric angle of 6° to 25°. An underweight body mass index (BMI) is a risk factor for development of SMA syndrome. There are few reports of the role of linear endoscopic ultrasound (EUS) in the diagnosis of SMA syndrome. We report a case of SMA syndrome, with normal BMI, that was diagnosed with the aid of linear EUS. Although SMA syndrome is not typically within the scope of practice of endosonographers, it is useful to get familiar with the findings.

Evaluating aortomesenteric parameters in a tertiary center of Nepal for superior mesenteric artery syndrome diagnosis and risk factors: cross-sectional study

“…Similarly, Lee et al 29 observed SMAS occurrences in patients with normal BMIs, suggesting a possible link between a growth spurt and SMA configuration changes. Wee and colleagues and Wang and colleagues also contradicted our findings, indicating that low BMI is not always a prerequisite for decreased AMA and AMD in SMAS cases 30 , 31 .…”

Teenager with upper gastrointestinal obstruction – keep in mind the rare causes

“…Any patient with sugestive symptoms for superior mesenteric artery syndrome should undergo imagistic investigation using upper gastrointestinal series, multisliced CT, CT angiography, magnetic resonance angiography, conventional angiography, ultrasonography and endoscopy (5,14).…”

Cauză rară de obstrucție de tract digestiv superior – importanța unei abordări multidisciplinare

“…Un pacient pediatric cu simptome sugestive pentru sindromul de arteră mezenterică superioară necesită investigații endoscopice și radiologice amănunțite precum: computer tomografie, angio-CT, imagistică prin rezonanță magnetică, angiografie, ecografie și endoscopie digestivă superioară (5,14).…”
