2024年7月20日 · Ultrasound is an additional modularity that can be used in the diagnosis of superior mesenteric artery syndrome. Characteristic findings include reduction of the aortic-mesenteric angle (angle <25° with the aorto-mesenteric distance <8–10 mm).

2021年11月15日 · Ultrasound. Several values on doppler ultrasound have been proposed that include: to suggest stenosis of 70% or greater: peak systolic velocity (PSV) should be ≥275 cm/s 4,7; From a different paper: to suggest stenosis of 50-69% 5: peak systolic velocity (PSV) should be >280 cm/s; end-diastolic velocity (EDV) >45 cm/s; mesenteric aortic ratio ...

2024年12月19日 · The superior mesenteric artery (SMA) is one of the three non-paired major splanchnic arteries in the abdominal cavity arising from the abdominal aorta and supplying the midgut; i.e. from mid duodenum to distal transverse colon.

2020年1月2日 · Doppler ultrasonography can accurately assess anatomic and physiologic features that are important for patient management including vessel patency, atherosclerotic burden, degree of arterial stenosis, and the number of arteries affected.

the abdominal aorta and major visceral arteries including the celiac artery, superior mesenteric artery (SMA) and inferior mesenteric artery (IMA). EXAM INITIATION: • Review prior imaging, particularly previous CT, MR, or catheter angiograms • …

2005年3月14日 · Ultrasound power colour Doppler imaging is useful in epidemiological screening of reduced aorto-mesenteric angle to diagnose suspected cases of SMA syndrome.

2024年11月13日 · Superior mesenteric artery imaging is essential in diagnosing abnormalities of the superior mesenteric artery. Imaging with CTA, MRA, Doppler ultrasound, and conventional angiography can identify blockages, diagnose mesenteric ischemia, or evaluate the effects of SMA syndrome.

Early diagnosis with contrast-enhanced computed tomography and revascularization can reduce the overall mortality in AMI. This article reviews practical etiological classification, pathophysiology of imaging manifestations and common pitfalls in intestinal ischemia.

Superior mesenteric artery (SMA) syndrome is a rare condition of duodenal obstruction, caused by the overlying SMA. Aim. To report on our experience with the management of SMA syndrome, drawing the attention to its existence. Material and Methods.

The useful diagnostic modalities are computed tomography as a standard tool and ultrasonography, which has advantages in safety and capability of real-time assessments of SMA mobility and duodenum passage.
