Cerebral hyperperfusion syndrome (CHS) after carotid endarterectomy (CEA) is devastating, and postoperative monitoring of cerebral perfusion is essential to prevent CHS. We report two cases of successful measurement of ocular blood flow using laser speckle flowgraphy (LSFG) for bedside assessment of the changes in cerebral perfusion after CEA. An 18.7% (case 1) and 47.7% (case 2) increase in ocular blood flow were measured postoperatively using LSFG compared with the baseline. LSFG might be applicable to evaluate cerebral perfusion after CEA.

颈动脉内膜切除术（CEA）后发生的脑灌注过多综合征（CHS）具有破坏性，术后对脑灌注进行监测对于预防CHS至关重要。我们报告了两例使用激光散斑血流图（LSFG）成功测量眼血流以床边评估CEA后脑灌注变化的病例。与基线相比，术后使用LSFG测量的眼血流分别增加了18.7%（病例1）和47.7%（病例2）。LSFG可能适用于评估CEA后的脑灌注。
