椎骨動脈起始部閉塞性病変に対する椎骨動脈-総頸動脈transposition  [in Japanese] Surgical Treatment for Patients with Bilateral Occlusive Vertebral Artery Lesions  [in Japanese]

Abstract

脳梗塞のうちposterior circulationが原因となる率は全体の約25%であり,このうち動脈硬化性病変が最も起こりやすい部位は椎骨動脈起始部である.しかし,めまいなどの非特異的な症状が多いことやMRA,頸部エコーなどでは起始部病変が診断しにくいことより,椎骨動脈起始部病変を診断することは容易ではない.また脳血管撮影でも起始部狭窄病変を見逃すこともある.ゆえに,頸動脈病変に比較してその頻度や予後についての詳細な報告は少ない.また,この椎骨動脈起始部病変が原因である場合の治療法の選択も確立されていないのが現状である.今回われわれは,椎骨動脈起始部病変に対して,厳密な手術適応のもとに施行した血行再建術の手術方法およびその成績について報告する.

We evaluated the surgical and long-term follow-up results of VA-CCA transposition in patients with bilateral VA occlusive lesions. Indications for this operation are: 1) symptomatic patients with the infarction in the cerebellum, brain stem or occipital lobe, 2) symptomatic patients with more than 500/0 VA stenosis with contralateral VA occlusion, 3) symptomatic patients with more than 750/0 bilateral VA stenosis at origin. In 13 patients, there were no deaths and no major complications. During the follow-up period, I patient died of a cardiac event, and another patient had a reattack due to the restenosis of VA stenosis. Another 11 patients showed no reattacks and good patency of VA. Although there have been no prospective randomized studies for this disease, VA-CCA transposition is a safe and useful treatment for patients with bilateral VA origin occlusive lesions.
