BACKGROUND
Clear evidence of cerebral blood circulation has not been shown after axillo-axillary bypass surgery in patients with subclavian steal syndrome.
METHODS
We investigated the cerebral circulation and blood flow in 3 patients receiving axillo-axillary bypass by RI angiography using 99mTc-dl hexamethyl propylene amine oxime (99mTc-HMPAO). Two patients had vertebral basilar cerebral symptoms which were related to decreased cerebral blood flow evidenced by 99mTc-HMPAO.
RESULTS
After the correction, cerebral symptoms disappeared and improved cerebral blood circulation detected by 99mTc-HMPAO-SPECT.
CONCLUSIONS
We concluded that axillo-axillary bypass was a fairly effective procedure to improve cerebral blood circulation evidenced by 99mTc-HMPAO-SPECT.
背景
锁骨下动脉窃血综合征患者行腋-腋旁路手术后，尚未有明确的脑血液循环证据。
方法
我们通过使用99mTc-二甲基己基亚丙基三胺五醋酸（99mTc-HMPAO）的RI血管造影术，对3例行腋-腋旁路手术的患者的脑循环和血流进行了研究。2例患者有椎基底脑症状，99mTc-HMPAO显示其与脑血流量减少有关。
结果
矫正后，脑症状消失，99mTc-HMPAO-SPECT检测到脑血液循环改善。
结论
我们得出结论，腋-腋旁路手术是一种相当有效的改善脑血液循环的方法，99mTc-HMPAO-SPECT已证实这一点。
