1/13. Successful management of severe aortocaval compression in twin pregnancy.In a patient with severe aortocaval compression, simultaneous brachial and femoral blood pressure measurements demonstrated the need for a 30 degrees left-down tilt to avoid significant obstruction of the vessels. When emergency cesarean section became necessary, proper positioning of the patient was readily accomplished.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/13. Succenturiate placenta diagnosed by ultrasound.The succenturiate placenta is a morphological abnormality, the antenatal recognition of which is important as vessels connecting the main placenta with the succenturiate placenta may rupture during labor and fetal death may ensue. In addition, retention of the placental material may lead to postpartum hemorrhage. We treated 5 patients with a succenturiate placenta and the antenatal ultrasonograms and related discussions are presented herein.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/13. Lupus anticoagulant. Implications for obstetric anaesthetists.Circulating lupus anticoagulant occurs in 5-37% of all patients with systemic lupus erythematosus. Its occurrence is not restricted to collagen vascular disease states. Lupus anticoagulant causes a prolongation of certain laboratory coagulation studies yet it is associated in vivo with a history of systemic intravascular thromboses. Placental vessels are also affected. Less than one in six pregnancies complicated by the presence of this auto-antibody is successful. Treatment of afflicted parturients with anti-platelet therapy has increased perinatal survival rates. Derangements in the coagulation profile and concomitant anti-platelet therapy confound the rational use of regional anaesthesia in the management of labour and delivery in these high-risk pregnancies.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/13. vasa previa: a major complication and its management.vasa previa is an extremely rare condition. Consequently it is not often considered in the differential diagnosis of antepartum or intrapartum hemorrhage. rupture of a fetal vessel may lead to sudden fetal death from exsanguination; therefore, this condition should be suspected in any antepartum or intrapartum hemorrhage. The blood that is lost should be tested for the presence of fetal hemoglobin. Other diagnostic tests to assess the degree of fetal distress are described. Four patients showing unusual presentations of vasa previa are reported. These cases demonstrate that fetal vessel rupture may occur independently of membrane rupture.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
5/13. Retroperitoneal sarcomas obstructing delivery: two case reports.Two patients with abnormal fetal lies underwent elective Caesarean section. Both abnormal lies were found to be due to retroperitoneal sarcomas overlying the bifurcation of the iliac vessels. One proved to be an inoperable and radioresistant fibrosarcoma. At seven and a half years after Caesarean section and following chemotherapy this patient is alive and well and has had two more children. The other tumour was a large myxoid liposarcoma which was completely removed at the time of Caesarean section. This patient is alive and well 18 months after operation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/13. 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) |
7/13. 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) |
8/13. 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) |
9/13. Intrauterine rupture of the umbilical cord during delivery.Two cases of bleeding from ruptured umbilical vein during delivery are reported. In one case the rupture was spontaneous, leading to fetal distress. In the second case the rupture was probably iatrogenic, and was caused by forceps delivery. Bleeding from ruptured umbilical vessel should be considered when a combination of variable decelerations during fetal heart rate monitoring, blood-stained amniotic fluid and fetal distress are detected during delivery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/13. fetal heart rate response to acute hemorrhage.Intrapartum fetal bleeding from an anomalous umbilical cord vessel has been associated with a perinatal mortality rate of over 50%. Fetal blood volume is relatively small. Thus, an insignificant hemorrhage by adult standards may quickly lead to fetal shock and death. This paper documents the fetal heart rate (FHR) response to acute intrapartum hemorrhage. The onset of fetal bleeding is marked by a tachycardia followed by a bradycardia with intermittent accelerations or decelerations. Small amounts of vaginal bleeding associated with FHR abnormalities should raise the suspicion of fetal hemorrhage. This condition demands prompt delivery and immediate reexpansion of the neonatal blood volume.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
