・急性期アテローム血栓性脳梗塞が進行性に悪化した場合,STA-MCAバイパス術が有効となる可能性がある.
・治療適応を慎重に検討すれば,5〜7割の患者がmRS 0〜2の自立生活,7〜9割の患者がmRS 0〜3の自立歩行可能なレベルを獲得できる可能性がある.
・急速悪化症例における急性期バイパス術には限界があり予後不良例が多い.
Endovascular recanalization is the primary strategy for the treatment of acute embolic stroke. However, atherosclerotic occlusions are often challenging to recanalize, and only medical therapy can be performed. In these cases, even the best medical treatment may not be effective, and the cerebral infarction progressively worsens. We believe that an emergency superficial temporal artery-middle cerebral artery(STA-MCA)bypass could be effective in these situations, after careful case selection. We use the following eligibility criteria: (1)atherosclerotic infarction; (2)cerebral ischemia with blood flow < 70% of the contralateral side; (3)progressively worsening symptoms or widening of the subcortical infarction despite medical treatment; and(4)surgery availability < 72 h from symptom onset.
Among the 35 patients who underwent urgent STA-MCA bypass from 2014 to 2020, 27(77.1%)gained gait independence, and the National Institutes of Health Stroke Scale(NIHSS)scores improved from a preoperative median of 8 to 3 at discharge. The modified Rankin score(mRS)improved from a preoperative median of 5 to 2 at discharge.
No intracerebral hemorrhages occurred due to hyper-perfusion syndrome. When we match it with other reports, this emergency surgery allows 76-90% of patients with progressive stroke to achieve gait independency.
