Would you advise mobility restrictions in a patient with Protein S deficiency and acute upper extremity DVTs but contraindications to anticoagulation (e.g., acute GI bleed) to reduce the risk of thrombus embolization?

This question is an interesting one and an incredibly specific scenario. I'll try to broaden the answer to cover a few more scenarios. So, the question gets at three elements: 1) Patient has an acute VTE, 2) Patient has a hypercoagulable state, 3) Patient has a contraindication to anticoagulation.

So, in general, bed rest is not advised in acute VTE. There is not really evidence that restricting activity reduces the risk of thrombus embolization in upper extremity DVT, and the broader VTE litera...
