[Color Doppler ultrasound in acute mesenteric ischemia: 2 case reports]

Acute mesenteric insufficiency is a surgical emergency with a difficult methodological approach. Its high mortality is mainly due to delay in the correct diagnosis. In turn this is due to the lack of specificity, especially in the early-middle phase of the clinical presentation, and of the laboratory data and abdominal radiographic findings. Echo-doppler ultrasound promises to be more accurate than conventional ultrasound in the diagnosis of visceral ischemia and may help to identify those patients who may require angiography. Two women presenting atrial fibrillation, abdominal pain, leukocytosis, hyperamylasemia were accepted in October 2000 ad March 2001. US colordoppler was performed 12 hours after admittance demonstrating a "stop" of enhancement of the superior mesenteric artery in one case and absence of enhancement in the other.
