Static and dynamic responses to hyperoxia of normal placenta across gestation with T2*-weighted MRI sequences.
Ultrasound Obstet Gynecol
August 2024
Objectives: T2*-weighted magnetic resonance imaging (MRI) sequences have been identified as non-invasive tools with which to study placental oxygenation in vivo. This study aimed to use these to investigate both static and dynamic responses to hyperoxia of the normal placenta across gestation.
Methods: We conducted a single-center prospective study including 52 uncomplicated pregnancies.
Background: Preterm labor and delivery is a major concern for patients with twin-to-twin transfusion syndrome undergoing fetoscopic laser surgery. A preoperative short cervix is a risk factor for preterm labor. Pessary placement is a short-acting intervention that may be useful to reduce this adverse event.

- A study evaluated how the size of excisional specimens affects the endocervical margin status in patients with adenocarcinoma in situ of the cervix, highlighting that larger lateral and anteroposterior diameters correlated with negative margins.* -
- Out of 95 patients who had excisional procedures, 80% had negative endocervical margins, while 20% had positive margins, with size dimensions playing a significant role in the margin status.* -
- Age also influenced the outcome, as patients over 45 were more likely to have positive endocervical margins compared to younger patients, despite having similar excisional specimen sizes.*
Objective: To evaluate the effect of gestational age at laser therapy for twin-to-twin transfusion syndrome (TTTS) on perinatal outcome.
Design And Settings: Single retrospective observational cohort.
Population: All consecutive pregnancies affected by TTTS and referred to our department between January 2013 and August 2020.
Background: Complete coagulation of the vascular equator (as in the Solomon technique) has been suggested to reduce postoperative complications such as twin anemia polycythemia syndrome and the recurrence of twin-twin transfusion syndrome following fetoscopic laser coagulation of chorionic vessels for twin-twin transfusion syndrome.
Objective: We aimed to evaluate the benefit of this technique on perinatal outcomes compared with selective ablation of anastomoses.
Study Design: We conducted a monocentric retrospective study comparing selective laser coagulation of anastomoses to the Solomon technique from January 2006 to August 2020.
