Superior mesenteric artery syndrome is a rare condition that causes a proximal small intestinal obstruction due to contraction of the
angle between the superior mesenteric artery and the aorta. Scoliosis surgery is one of the 15 reasons for superior mesenteric artery
syndrome, which can present with acute or chronic manifestations. Although conservative treatment is usually possible, surgical
treatment is required in certain cases that cannot be treated using conservative methods. In this paper, we describe a patient who
developed superior mesenteric artery syndrome ater scoliosis surgery and was treated with duodenojejunostomy due to failure
and complications of conservative treatment.
1. Introduction
Superior mesenteric artery (SMA) syndrome, irst deined
by von Rokitansky and referred to as SMAS by Wilkie, is a
rare condition resulting from increased pressure generated
by contraction of the angle between the SMA and the aorta,
near the third part of the duodenum [1, 2]. Approximately
15 causes have been described for SMAS; scoliosis repair
surgery is one of them [3–5]. In particular, ater correction
of the vertebral axis in scoliosis surgery, the angle between
the SMA and the aorta can become narrow, which can cause
obstruction of the duodenum [6]. SMAS can present with
acute manifestations, such as a proximal small intestinal
obstruction, or chronic manifestations, such as weight loss,
vomiting, decreased appetite, and postprandial abdominal
pain manifestations [3–5]. Conservative treatment is possible
with parenteral nutrition and nasogastric tube decompres-
sion [7]. However, in rare cases, the conservative methods
fail, and surgical treatment is required [8–10]. his report
discusses the treatment course and outcomes of a patient who
developed SMAS ater scoliosis surgery and was treated with
duodenojejunostomy because of the failure of conservative
treatment.
2. Case Report
he physical examination of a 17-year-old female patient
who presented to our orthopedics polyclinic complaining of
a protrusion on her back revealed kyphosis and a stooped
right shoulder, a right thoracic curvature with a let-facing
opening, a 6 cm high right thoracic hump on the front leaning
test, and shoulder asymmetry. However, no deicits were
identiied in the patient’s neurologic examination. Adolescent
idiopathic thoracic scoliosis (Type 1B according to the Lenke
classiication) was diagnosed via height measurements taken
in the standing position [11].
In the frontal plane, the measured Cobb angles were
50
∘
in the thoracic region and 30
∘
in the lumbar region
[12]. he patient’s bone development was classiied as Risser
Grade 3. She opted for surgical treatment, and her scoliosis
was corrected with global derotation; distraction and com-
pression were achieved with the use of titanium polyaxial
pedicle screws between the T3–L3 vertebrae in the prone
position. Additionally, 60 cc allograts were placed for fusion.
No abnormalities were observed during intraoperative neu-
rological monitoring. he patient was observed in the inten-
sive care unit for the irst 12 hours ater the surgery, and
