Abstract
Define funic presentation as it pertains to umbilical cord presentation.
Identify the risk factors for funic presentation.
Recognize the sonographic imaging characteristics of funic presentation.
Current guidelines agree that ________ is indicated in women with a history of spontaneous pregnancy loss or preterm delivery if the cervical length is 25 mm or less. Cervical Cerclage. Preterm Vaginal Delivery. External Version. Category III Fetal Heart Tracing.
To confirm the diagnosis of funic umbilical cord presentation, which of the following requirements must be applied during imaging? (1) Magnetic resonance imaging sequences with high temporal resolution and good contrast-to-noise ratios; (2) Use of a phased-array coil to maximize the signal-to-noise ratio. (1) Colposcopy imaging with magnification (2) Followed by an immediate loop electrosurgical excisional procedure. (1) Computed tomography imaging of the abdomen and pelvis without IV contrast; (2) Start scan at the level of T12 and end scan at the level of S1 using DFOV 200mm (larger if necessary to include the cervical anatomy). (1) Transvaginal longitudinal and transverse sonographic images of the lower uterine segment, uterine cervix, and presenting part; (2) If a free loop or loops of umbilical cord below the presenting part are detected, use color Doppler to confirm the diagnosis.
What is the correct definition of funic presentation? A condition where the umbilical cord descends through the cervix into the vaginal canal after the rupture of the amniotic membrane. A condition when a loop or loops of the umbilical cord lie between the fetal presenting part and the still-intact fetal membranes. Umbilical cord prolapse that occurs when the umbilical cord is located alongside the presenting part, but it is not detectable by the examiner. Unprotected umbilical blood vessels, which run through the amniotic membranes in the vicinity of the cervix.
What are the three most common types of umbilical cord prolapse? Velamentous Cord Insertion, Vasa Previa, Occult Prolapse. Funic Presentation, Occult Prolapse, Velamentous Cord Insertion. Overt Cord Prolapse, Funic Presentation, Occult Prolapse. Occult Prolapse, Vasa Previa, Occult Prolapse.
According to the authors, what is the primary strength of their research study? Confirmation that the use of a purse-string suture is the best cervical cerclage technique. A category III fetal heart tracing demonstrating minimal variability, bradycardia, and recurrent decelerations is the most reliable method of diagnosing funic presentation. The delivery mode of choice for all patients with persistent funic presentation is cesarean section. The introduction of a new indication for cervical cerclage to prevent the umbilical cord from prolapsing may justify an AIUM recommendation to include funic presentation imaging as part of a routine third-trimester sonographic examination.
