Here is sweet drop of ultrasound knowledge form the lecture "Ultrasound guided Vascular Access" in our Emergency Ultrasound BachelorClass. 🐝 It shows an example of subclavian vein catheter placement. Watch the video and answer the following quiz question.

Sasha Gordon, MD, shows you examples of each stage of intraventricular hemorrhage in neonates (grades 1 to 4), as assessed with cranial ultrasound (CUS).
Which feature is not present before grade 4?
Here we have an interesting patient case out of our Adult Congenital Heart Disease BachelorClass.
On echocardiography, where is the most common location of a perimembranous ventricular septal defect (VSD)?
A young female patient presents with a palpable, firm nodule on the right side of her neck/thyroid region. She is seeking a definitive diagnosis before committing to any surgical intervention.
B-Mode Ultrasound: Irregularly shaped nodule with visible microcalcifications. The thyroid capsule appears mostly intact; however, on the anterior aspect, there might be signs of some capsule destruction.
Scintigraphy: Slightly lower radiotracer uptake in the inferior pole of the right lobe compared to the surrounding parenchyma (but it is not that striking). The final step was *Shear Wave Elastography*. The results are reported together with the images!
How would you interpret the findings regarding the benign/malignant nature of the nodule?
Imagine you only have this long axis view in B-mode and with color Doppler.
Can you still detect something abnormal here?
Can you "eye ball" dyssynchrony? In echocardiography, patients with LBBB often exhibit a biphasic or paradoxical septal motion due to delayed left ventricular activation. However, abnormal septal motion can also result from other conditions, such as pericardial constriction or volume overload, making it essential to differentiate between these patterns. Carefully examine the echocardiographic images and identify which patient(s) show findings consistent with LBBB.
Which patient(s) have a LBBB?
Case: 42-year-old male presenting with precordial T-wave inversions.
Echocardiography: The 4CV reveals significant myocardial hypertrophy localized to the apex. The LV cavity demonstrates the classic "pointed" contour, known as the "Ace of Spades" sign. While radial motion appears visually preserved, left atrial enlargement suggests elevated filling pressures.
What additional information is gained in this patient by performing a speckle tracking analysis?
Looking at this patient's popliteal artery exam performed by Diagnostic Sonographer Julie Cardoso, it becomes clear that the patient has an aneurysm of clinically relevant size. However, the perfusion distally is still sustained. As explained by Dr. Andrey Espinoza, the main risks include rupture or embolization of plaque/s small thrombus formations causing occlusion of smaller arteries more distally.
Looking at the doppler waveform recorded from the lumen inside the aneurysm (longitudinal view), why is it dampened and biphasic?
This is not just a bad quality 2-chamber-view! We have also added one more loop from the same patient which shows the same pathology from a subcostal abdominal view.
Which life-threatening condition can you spot when looking at this loop?
