Analysis of the Feasibility of CDFI for Measuring the PSV and RI of Mesenteric Artery in Infant Intussusception to Guide the Clinical Treatment

Objective] To explore the feasibility of color Doppler flow imaging（CDFl） for measuring PSV and RI of mesenteric artery in infant intussusception to guide the clinical treatment. Methods]Totally 93 infans with intussusception diagnosed by CDFI and receiving the hospitalization in our hospital from 2001 to 2009 were analyzed retrospectively. Intestinal canal was examined by transabdominal ultrasonography with 3.5MHz and 7.5MHz transducers. CDFI was used to measure PSV and RI of mesenteric artery. Results]Gaseous enema reduction was successful in 85 cases with PSV≤30cm/s and RI〈0.75. Eight cases with PSV〉30cm/s and RI〉0.75 were treated successfully after operative reduction and intestinal resection and anastomosis due to the failure of routine reduction. The achievement ratio of routine reduction was 91.41%. Conclusion] Ultrasonic feature image combined with PSV and RI of mesenteric artery by of CDFI is valuable for judging the severity of infant intussusception and guiding the choice of the clinical treatment methods.
