Abstract:
Objective To evaluate the effect of surgical treatment in ischemic cerebrovascular disease using perfusion-weighted magnetic resonance imaging (PWI) technique.Methods The clinical and imaging data of 24 patients with ischemic cerebrovascular disease were analyzed retrospectively. Cerebral perfusion was compared before and after operation by PWI.Results In our series, there were 9 cases of stenosis or occlusion of unilateral internal carotid artery (ICA), 8 cases of unilateral stenosis or occlusion of middle cerebral artery (MCA), 5 cases of multiple stenoses of intra- or extracranial artery system, 2 cases of moyamoya disease. PWI revealed 1 case of normal regional cerebral blood flow (rCBF) and mean transit time (MTT), 15cases of normal rCBF with increased MTT, and 8 cases of decreased rCBF with increased MTT. 23 patients received surgical treatment. There were 13 patients performed by stent angioplasty, 4 patients by endarterectomy, and 6 patients by STA-MCA bypass surgery. Cerebral perfusion improved in 19 cases (82.6%), which included 12 cases (92.3%) performed with stent angioplasty, 4 cases (100%) with endarterectomy and 3 cases (50%) with STA-MCA bypass surgery.Conclusions Being a new type of examination, PWI is helpful to evaluate the status of cerebral perfusion. Surgical methods are effective in treatment of ischemic cerebrovascular disease.
