*n (%); ⁺median (range); °alternating leadership of neuroradiology (NR) and vascular surgery (VS) teams. T0–T1: initial catheterization through femoral artery attempted by NR. T1–T2: time delay between team takeovers. T2–T3: VS performing surgical access to carotid artery, endarterectomy of ICA and sheath implantation if needed. T3–T4: time from when NR took over again until successful endovascular thrombectomy and recanalization. T4–T5: time from recanalization to wound closure. T0–T5: total time between first cut or puncture (whatever came first) and wound closure (i.e. total duration of the rendezvous intervention)
