abstract

  • BACKGROUND: Necrotizing enterocolitis (NEC) is the most important gastrointestinal emergency in the neonatal period and early detection is very important for its management. Bowel ischemia-hypoperfusion is one of the main etiological factors. In the literature, a few studies have focused on arterial Doppler ultrasonography (DUS) features of splanchnic arteries; however, their clinical implications are not clear. OBJECTIVE: In this study, we aimed to quantitatively evaluate the blood flow features in the hepatic portal vein (PV) and hepatic veins (HVs) by using DUS in newborns with NEC. Patient-Method: Enrolled subjects were divided into two groups as patient (suspected/confirmed NEC, n = 24), and control group (n = 25). Daily serial DUS examinations were performed after the onset of the suspicion of NEC and continued until the initial day of the enteral feeding. Portal blood flow (PBF) and "hepatic blood flow ratio" (RHBF) were calculated manually by using DUS findings. Two groups were compared with respect to their PBF and RoHBF values. RESULTS: PBF and RHBF levels were significantly lower in patient group than those in control group. Clinical improvement in patients with NEC was associated with improvement in the PBF and RHBF. Cut-off level of the RHBF for the diagnosis of NEC was 0.66. CONCLUSION: DUS seems to be useful for the diagnosis and follow-up of NEC by providing quantitative information on liver blood flow. Daily measurements of the PBF and RoHBF in newborns with NEC may be beneficial to make the decision of starting enteral feeding.
