[CK] AVF thrombosis.

AVF thrombosis:(HD)
- timing: during or before or after ? 
- possible for doing HD via that AVF? 
- evaluation: thrill, bruit, doppler, and so on. 

HX + P/EX = QRAAA + ASSOCIATED + OPDC + P/EX

- generally: total occlusion, acute occlusion
- if it's not totally occluded
  = no urgent intervention needed(Evaluation on Monday would be good enough)
  = no heparin infusion needed.
- no de-clot over the weekend per IR.


- MOSTLY => EVALUATION on MONDAY(Vascular = no urgent -> IR = Monday !, something like that....)
