During a 3-year period, sonographic evidence of portal venous gas (PVG) was found in 11 patients. Of these, 10 patients were examined for clinically suspected necrotizing enterocolitis (NEC). In the 11th patient, suffering from nephroblastoma, PVG was detected by routine sonography. Radiographic examination, performed in nine of 11 patients did not show any PVG. Intestinal pneumatosis was radiographically identifiable in only four of these children, whereas eight of 11 patients with sonographically detectable PVG also had sonographic evidence of intramural gas. Follow-up examinations in five patients showed cessation of PVG soon after onset of adequate therapy, indicating that ultrasonography is also a reliable method for monitoring NEC. Sonographic evidence of PVG, however, may be limited to the time before onset of therapy.
在3年期间，11例患者发现门静脉气体（PVG）的超声证据。其中，10例患者因临床怀疑坏死性小肠结肠炎（NEC）接受检查。第11例患者患有肾母细胞瘤，通过常规超声检测到PVG。11例患者中的9例进行了放射学检查，未显示任何PVG。这些儿童中只有4例在放射学上可识别肠壁积气，而11例超声可检测到PVG的患者中有8例也有壁内气体的超声证据。5例患者的随访检查显示，在充分治疗开始后不久PVG消失，这表明超声也是监测NEC的可靠方法。然而，PVG的超声证据可能仅限于治疗开始前的时间段。
