Thrombectomy complications

Had my first mechanical thrombectomy for DVT. Wondering about complications of this procedure? The bleeding/CMS changes make sense. The patient’s leg was still red with edema after the procedure, this is how the patient presented. Wondering if this is normal and for how long can this happen? Any other common complications you’ve seen? I asked several nurses on the floor but no one really had experience with this. I tried to look up as much as I could but I find personal experience helps me learn best. Thank you in advance!
