[PDF] Superior mesenteric artery syndrome: CT and ultrasonography findings. | Semantic Scholar (2024)

MDCT is preferable imaging modality compared to barium study because it can provide the exact angle between SMA and aorta which is a essential imaging sign for diagnosis.

The results show the importance of the endoscopic suspicion of SMA syndrome; the preponderance of a long-standing and chronic onset; a femalepreponderance; the important of the nutritional counseling for the treatment; no need of surgical intervention; and better diagnostic accuracy of the narrowing of the aorta-SMA distance.

Patients with SMA syndrome were observed among underweight women diagnosed with FD, and their symptoms may be associated with bacterial overgrowth.

This study helps in stating the values of aortomesenteric distance and angle for different BMI categories that can be used in CT-based diagnosis of SMAS in a South Asian population.

Two young female patients referred to the emergency department with history of abdominal pain and vomiting were imaged with ultrasonography and Contrast enhanced Computed Tomogram (CT) of the abdomen and pelvis with CT abdominal angiography and the Aortomesentric distance (AMD) was calculated.

Therapy of SMAS includes weight gain to increase the aortomesenteric angle, but surgery is indicated in symptomatic patients when conservative management failed, and laparoscopic duodenojejunostomy seems to be a first-choice surgical options.

A strong positive correlation was observed between BMI and the SMA–aorta angle, indicating that the angle increases with increasing BMI, which reduc es the risk of developing SMA syndrome.

Right movement of the SMA diagnosed by unenhanced CT is associated with SMA syndrome, according to the shortest distance between the parallel line that passes through the center of the aorta to the line that bisects the spine and SMA.

The aorto-mesenteric clamp is a rare radiological finding which does not always justify the supported clinical data, and the superior mesenteric superior artery syndrome should be considered as a diagnosis of exclusion after performing an adequate clinical study when the situation of the patient requires it.

This is the first report of the use of computed tomography in a patient with classic features of superior mesenteric artery (SMA) syndrome and it was possible to show that CT signs improved after clinical symptoms disappeared during adequate nutritional therapy.

CT angiography combined with 3D reconstructions is a noninvasive technique that may have a complementary diagnostic role similar to that ofAngiography in patients with a classic clinical presentation suggestive of superior mesenteric artery syndrome.

The diagnostic limitations of the routine barium meal studies can be abolished by hypotonic duodenography and patients with persisting signs and symptoms after surgery for ulcer should be re-examined with this condition in mind.

The value of hypotonic duodenography in the diagnosis of the syndrome is emphasized and the importance of follow‐up periods of 6 months to 6 years is emphasized.
