#POCUS puzzle 🧩of the day. Can you put together the pieces and arrive at an unifying diagnosis? Go through the thread 🧵below.
Context: #dialysis patient, physical examination #FOAMed#Nephrology#MedEd
#eVExUS (= extended #VExUS) includes evaluation of additional veins when the original 3 veins are unobtainable or unreliable for any reason.
Below👇🧵 is an illustrative case showing abnormal pattern in all these veins.

1⃣ Parasternal window
2⃣ Parasternal window continued
3⃣ Parasternal window, short axis plane
Often underutilized, can get an idea of TR when apical window is difficult, can do RVOT Doppler as well
Focused question: Is HTN in a #dialysis patient always⬆️ intravascular volume? Remove💧?
Clinical: ESRD due to polycystic kidney disease, BP 160s/~100, IVC not well-visualized.
Next step to assess RAP: #VExUS
Below is hepatic vein Doppler

2/ 👆What do you think?
3/ 👆HV #VExUS is showing resiprophasic D-reversal.
We commonly talk about S-reversal. Where do you see D-reversal? - constrictive pericarditis, tamponade, some cases of severe pulmonary HTN.
Next step: Evaluate the🫀
👇PV looks fine
#POCUS enthusiasts, is this IVC normal, abnormal? (asking about possibilities, not definitive conclusions) #FOAMcc#MedEd#Nephpearls

#POCUS answer:
I deliberately avoided clinical context in the original tweet to gather multiple opinions.
Image obtained from a thin, trained athlete with resting HR in 40s-50s.
A dilated IVC is commonly seen in this setting with no right heart pathology. In addition, particulate… twitter.com/i/web/status/1…
