What complication may arise from performing ambulatory phlebectomy on the lateral aspect of the knee?

The risk of foot drop as a complication from performing ambulatory phlebectomy on the lateral aspect of the knee relates to the possibility of nerve injury, particularly to the common peroneal nerve. The common peroneal nerve wraps around the fibula at the knee and is susceptible to compression or injury during surgical procedures in this area. If the nerve is damaged, it can result in weakness or paralysis of the muscles that control ankle dorsiflexion, leading to foot drop – a condition where the individual cannot lift the front part of the foot, resulting in dragging of the toes when walking.

While hematoma, skin ulceration, and infection can indeed be complications associated with any surgical procedure, foot drop is particularly relevant to this specific location due to the anatomical considerations and the potential for nerve involvement during the procedure. Understanding these risks is crucial for clinicians performing ambulatory phlebectomy and for informing patients about possible complications.
