Treatment of symptomatic complex posterior circulation cerebral artery stenosis with balloon-mounted stents: technique feasibility and outcome.

Purpose: This study aimed to retrospectively analyze a series of patients with complex posterior circulation stenosis who underwent stent-assisted angioplasty to evaluate the feasibility of the procedure and summarize the experience with regard to complications.

Methods: A total of 16 consecutive patients with 27 complex posterior circulation artery stenoses refractory to medical therapy were enrolled. Technical success rate, periprocedural complication, and long-term follow-up result were evaluated.

[Correlative study of carotid transient ischemic attacks and intracranial or extracranial angiostenosis].

Objective: To investigate the relationship between the clinical features of carotid transient ischemic attacks (TIA) and the intracranial or extracranial angiostenosis.

Methods: Location and degree of stenosis of involved arteries were examined by the digital subtraction angiography in 52 patients with carotid TIA.

Results: Intracranial or extracranial vascular lesions of different degrees were revealed in 45 patients (86.
