Abstract

Abstract:

Objective

To present treatment results with stent angioplasty of vertebral stenosis in post circulation ischemic patients.

Methods

Vertebral artery stent angioplasty were proformed in totally 47 patients confirmed vertebral artery stenosis with 52 stents. Among them, there were 46 stents implanted in vertebral ostim and 6 stents in V4 segment. All of the patients were followed by digital distraction angiography(DSA) and CT angiography. Average follow up duration was 6.3 months.

Results

ALL the stents were implanted successfully. Symptoms were improved in 85.1%(40/47) of the patients. The stenosis rate before stenting were (75.2±6.7)% compared with (7.6±6.1)% post stenting. In-stent recurrent stenosis (IRS) were conformed in 9(17%) stents, however 8 stents were implanted in vertebral ostium(V1 segment),1 stent were in V4 segment.

Conclusions

In experienced hands, stenting for symptomatic VAS can be accomplished with a very high success rate (100%),with few complications. We conclude that endovascular stenting of vertebral artery stenosis is safe and effective for ischemic disease.IRS should be avoided.
