The Reconstructions for Vertebral Artery Stenosis at the Origin. A Comparison between PTA and Surgical Reconstructions.
To date in our hospital, surgical reconstructions and percutaneous transluminal angioplasty (PTA) were carried out in 168 patients with vertebral artery (VA) stenosis at the origin. In this article, we discuss the comparison between surgical reconstructions and PTA, especially regarding long term follow up, patency and complications. PTA is a less invasive treatment for VA stenosis at the origin than surgical reconstructions. However, restenosis after PTA occurred in 20% of the patients. On the other hand, restenosis after surgical reconstructions did not emerge even in long term follow up. An embolism after PTA occurred in 2.6% of the cases. However, the embolism occurred in only the first 10 patients of our series, after that there was no embolism. We concluded that PTA was the first choice for VA stenosis at the origin, if the angiogram did not reveal any PTA difficulty. If restenosis after PTA was performed, we selected surgical reconstruction for VA stenosis at the origin.
