This study included 16 patients with SMAO. Angiograpy was useful method for its daignosis. But in its early stage, we could hardly determine which patient should be subjected to angiography, and non-invasive and simple examination, is needed for its early diagnosis.
In the cases of abdominal emergency, superior mesenteric artery (SMA) can be reviewed by computed tomography (CT), and be enhansed by contrast CT. SMA is considered to be not enhanced at SMAO. When SMA is enhanced on CT, SMAO should be ruled out.
Portal blood flow (PVF) is considered to decrease, when SMA is occluded. If SMAO has specific portal hemodynamics, its early diagnosis will be possible by non-invasive PVF measurement using an ultrasonic duplex system (PD). We investigated the portal hemodynamic changes in experimental SMAO, peritonitis and ileus using 24 mongrel dogs. Our results showed that PVF to cardiac output ratios (PCR) of SMAO models were under 10% and in contrast, these of other were over 10%. So SMAO models were distinguishable from others. These suggested that PCR measured by PD and echocardiography was useful indicator of early diagnosis of SMAO.
