Arterial or Atypical Clots? Think APLS, PNH, and MPN
Allison Fitzgerald, Heme/Onc Fellow at Dana-Farber, posted on X:
”Today I learned that while clots in veins can be caused by all sorts of things, clots in arteries are usually caused by cancer or anti-phospholipid syndrome (APLS).
Adding paroxysmal nocturnal hemoglobinuria and myeloproliferative neoplasms (which is a subtype of cancer, but more specific, I suppose) to this list.
So clots in arterial or weird venous places:
– APLS
– PNH
– MPN
– HIT
– hyperhomocysteinemia”
