Pulmonary Embolism—A Century of Progress

ANZ Journal of Surgery, EarlyView.
Reviews a century of progress in the diagnosis, prevention, and management of pulmonary embolism; from the first successful surgical embolectomy in 1924 to advanced imaging, pharmacological thromboprophylaxis, and treatment. In the 21st century, advances include catheter‐directed thrombolysis or mechanical thrombectomy under decision‐making guidance of

Agreement between cardiac cycle time intervals and myocardial velocities measured by automated analysis of color tissue Doppler cine loops and by manual tracing of spectral pulsed‐wave tissue Doppler waveforms of sheep fetal heart under normal and pathological conditions: An experimental study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Automated cTDI in sheep fetuses provided reproducible measurements of myocardial velocities and heart rate that align well with manual pulsed‐wave TDI. For cardiac cycle duration metrics, the two modalities are not interchangeable. These findings support that automated cTDI is well suited for longitudinal assessment under both physiological and ...

Prenatal imaging phenotypes and outcomes of umbilical‐portal‐systemic venous shunts in singleton and twin pregnancies: A historical cohort study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
This retrospective cohort compared umbilical‐portal‐systemic venous shunts in singleton and twin pregnancies. Type III was the most common subtype in singletons, whereas Type II was the most common in twins. Fetal growth restriction was more frequent in twins, but primary structural anomaly rates were similar.

Diagnostic performance and feasibility of classifying placental umbilical cord insertion during routine prenatal ultrasound

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Classification of placental umbilical cord insertion is feasible within the routine prenatal ultrasound examination, and reliably excludes abnormal insertion, although positive predictive values were low. Abstract Introduction Abnormal cord insertion (velamentous or marginal) is associated with adverse perinatal outcomes, and guidelines recommend ...

Pebbled mosaic‐like heterogeneous echogenicity in ovarian immature teratomas and correlation of ultrasound patterns with pathological grades

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
This study characterizes heterogeneous mottled grayscale ultrasound echoes of ovarian immature teratoma as the “pebbled mosaic sign,” noting solid lesions correlate with advanced pathological grades. Preoperative identification of immature tissue informs operative stratification. Abstract Introduction Ovarian immature teratomas (ITs) are rare malignant
