Minimally invasive fetal surgery Minimally invasive fetoscopic surgery is operated on fetuses by utilizing small cut, a fetoscope and sonography. Sometimes, fetal surgery can be performed without cut or fetoscope; however, it is constantly performed with an ongoing cross-sectional view given by sonogram. As the fetal surgery for spina bifida is operated in antenatal period it is additionally called as prenatal spina bifida surgery operation. A minimally-invasive fetoscopic is a small surgical instrument which is brought into the uterus utilizing ongoing video imagery from fetoscopy and ultrasonography. This is a less invasive method than open fetal surgery. Some fetal surgeries can be performed with only a small guided wire sent percutaneously, while in different cases a small opening might be required in the mother's mid-region. Signs for minimally-invasive fetoscopic surgery include: Spina bifida Twin transfusion disorder Fetal bladder hindrances Aortic or Pulmonary Valvuloplasty Atrial Septostomy Inborn diaphragmatic hernia. There are different surgical strategies for antenatal repair of spina bifida. Many research reports demonstrate that the results of prenatal fetal surgery are obviously better than those performed in the postnatal period.
