A case of popliteal artery aneurysm after arthroscopic cystectomy of a popliteal cyst is an uncommon complication, and no case has been reported. We present a case of pseudoaneurysm of the popliteal artery after arthroscopic cystectomy of a popliteal cyst 2 months after surgery. Open excision of the pseudoaneurysm and popliteal artery pin-point repair were done. At 30 months' follow-up, both the tibialis posterior and dorsalis pedis pulsations were felt equally on both sides with normal sensations over the limb. Retrospectively reviewing the case, we found that the relation of the popliteal artery and popliteal cyst on preoperative magnetic resonance images can predict the complication of pseudoaneurysm of the popliteal artery. It is better not to shave the lateral aspect of the cyst while performing arthroscopic cystectomy when magnetic resonance images show that the popliteal artery is close to the cyst.
腘窝囊肿关节镜术后发生腘动脉假性动脉瘤较为少见，尚未见报道。我们报告 1 例腘窝囊肿关节镜术后 2 个月发生腘动脉假性动脉瘤。行假性动脉瘤切除术和腘动脉缝扎术。术后 30 个月随访，双侧胫后动脉和足背动脉搏动良好，肢体感觉正常。回顾该病例，术前磁共振成像显示腘动脉与腘窝囊肿的关系可预测假性动脉瘤的发生。当磁共振成像显示腘动脉靠近囊肿时，关节镜下切除囊肿时最好不要刮除囊肿的外侧。
