Five patients underwent cerebral revascularization operations during which Biemer clips were used to occlude temporarily a branch of the middle cerebral artery. Postoperative angiograms revealed stenoses at the sites where the clips were applied. Excessive clip closing forces may have caused significant endothelial injury, which then produced the stenoses. Clips that exert a minimal occlusive force would avoid this response and are recommended for temporary occlusion of cortical arteries.
5名患者接受了脑血管重建手术，术中使用比默夹暂时夹闭大脑中动脉的一个分支。术后血管造影显示夹闭部位出现狭窄。夹闭力过大可能导致了严重的内皮损伤，进而产生狭窄。施加最小闭塞力的夹子可避免这种反应，建议用于临时夹闭皮质动脉。
