[Clinical observation of middle cerebral artery angioplasty in treatment of subcortex cerebral watershed infarction with moderate or severe disabilities].

OBJECTIVE

To assess the safety and effectiveness of middle cerebral artery angioplasty in treatment of subcortical watershed infarcts (S-CWI) with moderate or severe disabilities.

METHODS

From June 2011 to May 2012, 5 S-CWI patients (six lesions) with moderate or severe disabilities combining severe stenosis in Ipsilateral middle cerebral artery received middle cerebral artery angioplasty in Interventional Radiology and Vascular Surgery Department, Peking University Third Hospital. We observed the neurological score before and after angioplasty and assessed the improvement of neurological functions.

RESULTS

The National Institute of Health stroke scale(NIHSS) scores were decreased by 4-6 points and modified Rankin scale(mRs) scores were decreased 1 point in 7 days. In the 3 months' follow-up, 4 patients' mRs scores were 1 point, and 1 patient's was 2 points. In the 1-year follow-up, there were no new strokes and instent restenosis events.

CONCLUSION

Middle cerebral artery angioplasty in treatment of S-CWI with moderate or severe disabilities is beneficial.
