Splenic artery: Peak systolic velocity of normal fetuses

Objective To establish a reference range of splenic artery peak systolic velocity 1(SpA-PSV) in the normal singleton pregnancies (14-40 weeks). Methods A prospective descriptive study was conducted on uncomplicated singleton pregnancies with normal fetuses and accurate gestational age were recruited...

Objective To establish a reference range of splenic artery peak systolic velocity 1(SpA-PSV) in the normal singleton pregnancies (14-40 weeks). Methods A prospective descriptive study was conducted on uncomplicated singleton pregnancies with normal fetuses and accurate gestational age were recruited into the study. The Doppler measurements of SpA-PSV were performed by the experienced sonographers with the high-resolution machine (Aloka Prosound alpha-10, Tokyo, Japan, or Voluson E8, GE Healthcare, USA). Results A total of 540 measurements were performed, ranging from 15 to 30 for each gestational week (GA). The best regression model between GA and SpA-PSV was observed to be linear function with an equation as follows: SpA-PSV (cm/s) = -1.433 +1.186 (GA, weeks) (r2 = 0.573). The table of nomogram for various percentile ranges was constructed. The results show a continuous increase in SpA-PSV over the period from 14 to 40 weeks. Conclusion A nomogram for SpA-PSV for each GA during 14-40 weeks was constructed. This reference range may be a useful non-invasive tool in risk assessment for fetal anemia, especially due to homozygous alpha-thalasse-mia-1 or fetal isoimmunization. 2014-08-30T02:25:07Z 2014-08-30T02:25:07Z 2010 Article 9320067 10.1007/s00404-009-1162-5 19562358 AGOBE http://www.scopus.com/inward/record.url?eid=2-s2.0-77950628241&partnerID=40&md5=a64aa9e949c83172c51683af2607641c http://www.ncbi.nlm.nih.gov/pubmed/19562358 http://cmuir.cmu.ac.th/handle/6653943832/2589 English
