Rationale: A carefully designed intracranial stent-assisted angioplasty (SAA) is presented here that may prevent subsequent branch artery occlusion.
Patient concerns: A 72-year-old man with a 3-month history of progressive and intermittent vertigo without any obvious trigger, accompanied by nausea.
Diagnoses: Intracranial atherosclerotic disease.
Interventions: the patient underwent intracranial SAA in accordance with the procedure described here.
Outcomes: The patient's paroxysmal vertigo completely subsided, with no complications during the short-term follow-up.
Lessons: This novel intracranial SAA procedure is safe and may reduce the risk of subsequent artery occlusion.
