Illustrative cases of endovascular recanalization for subacute to chronic atherosclerotic basilar artery occlusion (BAO). Images (A–E) were of the angioplasty procedure for patient 18. (A) Total occlusion of the BA (arrow). (B) The guidewire traversed the occlusion site. (C) The angioplasty procedure with the conventional balloon. (D,E) Angiographic result after conventional balloon angioplasty. Images (F–J) were of the angioplasty procedure and follow-up digital subtraction angiography (DSA) data from patient 7. (F) Total occlusion of the BA (arrow). (G) The angioplasty procedure with the conventional balloon. (H) The angioplasty procedure with the drug-coated balloon (DCB). (I) Angiographic result after DCB angioplasty. (J) Angiographic result at the 4-month follow-up. Images (K–O) were of the angioplasty and stenting procedures for patient 16. (K) Total occlusion of the BA (arrow). (L) The angioplasty procedure with the conventional balloon. (M) The angioplasty procedure with the DCB. (N) Instant restenosis occurred at the initial segment of the BA after DCB angioplasty (arrow). (O) Angiographic result after remedial stenting.
