title: Stent-assisted mechanical recanalization for symptomatic subacute or chronic middle cerebral artery occlusion.
abstract: To assess the feasibility and short-term effects of treating patients with subacute or chronic middle cerebral artery (M1) occlusion by stent-assisted mechanical recanalization. Six patients with cerebral arteries occlusion underwent surgery. Six cerebral arteries occlusion in 5 patients were successfully recanalized. On postoperative day 1, four patients' symptoms were relieved and two patients' symptoms were exacerbated, of which one was significantly improved after 3 days, the other one's symptoms were recovered to preoperative levels in 2 weeks. No patients died after surgery. No stroke or transient ischemic attack occurred. The average follow-up of was 4.2 months, no worsening of condition, recurrence or death occurred. The results indicate that for patients with subacute or chronic middle cerebral artery (M1) occlusion, mechanical recanalization was technically feasible under the premise of strict case screening. Mechanical recanalization is able to improve ischemic symptoms and promote dysfunction restoration. But its long-term effect remains to be evaluated by further large samples, long-term follow-up studies.
