E-031 vertebrobasilar junction aneurysms associated with subclavian steal physiology: Should an asymptomatic subclavian artery occlusion be treated?

Abstract

to 2020. We evaluated the change in NIHSS from presentation to hospital discharge as well as mRS at discharge and 3 months. We further evaluated for stent or vessel reocclusion as well as symptomatic hemorrhagic conversion as the cause of clinical decline. Results There were twenty procedures in nineteen patients during this time period. In three procedures acceptable caliber improvement was achieved using angioplasty alone (15%), with the other 17 procedures requiring a stent. Fourteen procedures (70%) resulted in improvement in NIHSS following the procedure and upon discharge. Out of the 6 procedures with worsening clinical outcome, 1 had reocclusion of the lesion, 2 with symptomatic hemorrhagic conversion, and 1 with perforator occlusion. Eleven cases resulted in mRS less than or equal 2 at 3 months and 3 patients had passed away by 3 months. Conclusion Even though rescue angioplasty with or without stenting can have a high rate of periprocedural morbidity, it leads to marked clinical improvement in the majority of the patients in this selected cohort.
