Here’s the latest question (in a nutshell):
Why does more lower extremity DVT’s seem to start in the left leg versus the right leg?
It is likely due to the vessel anatomy of the left pelvic region. The left common iliac vein lies posterior to the right common iliac artery causing a compression of the vein that is thought to be a contributing factor to the development of DVT.
Now for a side story and question:
A young woman, recently post-partum, presented to an urgent care with severe pain in her left leg. The physician on-duty orders a venous duplex scan to rule out DVT. The technologist performing the exam determines it to be negative for DVT (no blood clot present). So the young woman is discharged with appropriate instructions. Two days later the same young woman returns to the urgent care with a severe increase in the level of pain in her left leg. Once again, a venous duplex scan is ordered. The exam is now performed by technologist number 2. And of course, DVT from top to bottom. Undeniable, no flow whatsoever, DVT.
Of course, this situation raised some eyebrows. The two scans were compared and it was determined that neither of the two technologists were wrong.
Anyone care to venture a guess or speculate what may have occurred or what the patients’ diagnosis was?
You have the floor my friends!
A more discerning eye noticed that the spectral doppler analysis of flow in the CFV on scan number one demonstrated loss of phasicity.
