Yesterday we visited Hartford for the weekly ultrasound and were attended to by Dr. Feldman. She calculated a fetal weight of 2lbs, 5 oz. at this point, and the CCAM at 17 cc's, with a CVR of .65. Upon hearing this information, Victoria became understandably upset, asking why the reading was less than the reading obtained in Philadelphia the week before of 22 cc's. The Dr. explained that there may be slight variations in the way that different doctors measure the CCAM, but that the important thing to monitor was the heart and any distress it may be having (signs of hydrops). There were no signs of distress and little Maya was very active.
It is a little disturbing that such variations in measurement have been occurring. I do not know whether it is due to training differences or equipment differences. I do know that the measurements seem to be based on two axis measurements that are then calculated as volume in Hartford, and the ultrasounds are on more rudimentary equipment with lower resolution in Hartford. In Philadelphia I expect the state-of-the-art equipment allows many more measurements from different angles that allow for a more exact calculation for the irregular shape of the CCAM. Whatever the cause, we are pleased with our decision to work with Children's Hospital of Philadelphia for management of this case.
Victoria, Brianna and I have all felt Maya moving around lately. It is a very exciting time to bond with our new child and we are all looking forward to welcoming her into this world, whichever way it needs to occur.
