Irrerugularly Irregular rhythm = Afib Afib --> stasis of blood in the Heart ---> Thrombus formation Thrombus will embolize to the (likely) the popliteal artery leading to acute limb ischemia

to me, this is a process of elimination question.

Fasciotomy and bosentan don't make sense.

Clopidogrel and aspirin kinda make sense, Except Treatment of DVT is not part of their clinical use. (Clopidogrel 429 and aspirin 475 of FA 2019).

So we're left w Embolectomy.

PS. Thrombolytics and Direct Factor Xa inhibitors are used for DVT

Initially i was stuck between embelectomy and fasciotomy, mainly because the pt did seem to have some symptoms of compartment syndrome: pain, pulseless, pallor, perishing cold (remember 6Ps) so i thought maybe fasciotomy could be an answer.

However, fasciotomy is something that would usually occur due to neurovascular compromise, which commonly happens from trauma. So i went with an embolus, since the pt had irregularly irregualr rhythm, prediposing to thrombus/embolus forming, with eventual occlusion.
