Diagnosis of spontaneous isolated superior mesenteric artery dissection with ultrasound: A case report

Figure 1 Gray-scale ultrasound showed the superior mesenteric artery dissection and abdominal aorta. A: Ultrasonic longitudinal view demonstrated the opening of superior mesenteric artery dissection (SISMAD) (orange arrow); B: Transverse view demonstrated the opening of SISMAD (orange arrow); C: Ultrasonic longitudinal view showed the distal end of SISMAD (orange arrow); D: Transverse view showed the distal end of SISMAD (blue arrow); E: No abnormal echo was observed in the abdominal aortic lumen (orange arrow).

Figure 2 Doppler ultrasound showed the blood flow of the superior mesenteric artery dissection. A: Ultrasonic longitudinal view showed the flow at the opening of the superior mesenteric artery dissection (SISMAD); B: Ultrasonic transverse view showed the flow at the opening of the SISMAD; C: Color Doppler flow imaging showed the true and false lumens of the SISMAD; D: True lumen velocity of superior mesenteric artery dissection was measured by spectral Doppler.

Figure 3 Contrast enhanced computed tomography (CECT) showed superior mesenteric artery dissection. A: Cross-sectional view of the superior mesenteric artery dissection (SISMAD) (orange arrow) on CECT; B: Sagittal view of proximal SISMAD on CECT (orange arrow); C: Sagittal view of distal SISMAD on CECT (orange arrow).
