1/8. Placental pathology casebook. Serpentine aneurysms of the placenta with fetal consequences.Two cases of placental surface vessel aneurysms are presented. One case was associated with severe fetal intrauterine growth restriction and fetal thrombocytopenia. The other case was associated with "molar transformation" of placental villous tissue.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/8. hematoma of the umbilical cord with acute antepartum fetal distress. A case report.In a case of spontaneous hematoma of the umbilical cord, no pathologic lesion was found in the umbilical blood vessels. However, an extremely short cord (14 cm) may have contributed to the vessel rupture. A prolonged deceleration discovered during a routine nonstress test led to emergency cesarean section, with delivery of a healthy neonate.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
3/8. thrombosis of the right umbilical artery, presumably related to the shortness of the umbilical cord: an unusual cause of fetal distress.This case report concerns a late pregnancy complication, clinically apparent as severe variable decelerations in the first stage of labor. Emergency cesarean section delivered a mildly asphyxiated full-term newborn infant. Examination of the umbilical cord revealed a thrombus of the right umbilical artery, near the fetal side, confirmed by histological examination. The total length of the umbilical cord, only 30 cm, was below the limit necessary for uncomplicated delivery of the fetus near term. Transient stretching during fetal descent is thought to be responsible for constriction of the umbilical arteries, blood flow sludging and thrombosis. Although only a few cases have been reported, thrombosis of the umbilical vessels has to be considered whenever the fetal heart rate pattern shows unexplained variable decelerations.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/8. fetal distress secondary to fetal vessel perforation after amniocentesis. A case report.Fetal vessel perforation during amniocentesis resulted in severe fetal distress and a 5-cm hematoma at the perforation site.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
5/8. Fetal hazards of the intrauterine pressure catheter: five case reports.Five patients with fetal complications associated with the use of an intrauterine pressure catheter in labour are described. In four, a fetal vessel was punctured either by the catheter or its introducing sheath. In the remaining patient, cord compression resulted from entanglement with the catheter. These problems may be minimized by a careful catheter introduction technique.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/8. Perforation of a placental fetal vessel by an intrauterine pressure catheter.Perforation of a fetal vessel on the placental surface by an intrauterine catheter is reported. The immediate recognition of this unusual complication is important. To minimize the risks of perforation, haemorrhage and infection, several precautions should be observed when inserting the catheter.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
7/8. Decreased fetal movements associated with umbilical cord complications.In three of 1,094 cases of cord complications the mothers experienced reduction of fetal movments until cessation. In these three instances the fetal heart beat was audible but changes appeared on the fetal heart rate monitor. The course of loss of fetal movements resembled that seen in cases of placental insufficiency. It is suggested that the reduced fetal movements and the changes in fetal heart rate were due to a diminished blood flow in the cord vessels as a result of gradual cord compression.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/8. Sonographic demonstration of nuchal cord and abnormal umbilical artery waveform heralding fetal distress.Ultrasound examination of a 30-week fetus, appropriate for gestational age, revealed a nuchal cord and absence of end-diastolic velocities in the Doppler waveforms of the umbilical artery. cardiotocography suggested impending fetal distress, clinically confirmed following expedient abdominal delivery. We suggest that Doppler velocimetry of the umbilical vessels may be useful in the assessment of viable fetuses with a sonographic diagnosis of a nuchal cord. Conversely, a nuchal cord should be considered as part of the differential diagnosis of abnormal Doppler velocimetry of the umbilical vessels.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
