Alternative Postoperative Analgesia Technique for Peripheral Vascular Revascularization: A Case Report.

Peripheral arterial disease (PAD) patients often require surgical peripheral vascular revascularization (PVR), in which postoperative pain management can be challenging. This case report details a 43-year-old female patient with PAD who underwent urgent femoral popliteal bypass with an inverted ipsilateral great saphenous vein and left femoral endarterectomy. Due to contraindications for neuraxial anesthesia and the necessity for continuous anticoagulation, the procedure was performed under general anesthesia (GA) and an unconventional technique with intraoperative perineural catheter (PC) placement to guarantee adequate postoperative analgesia. The surgeon inserted the PC in the vicinity of the femoral nerve under direct visualization before surgical closure. Postoperative analgesia was successfully managed, demonstrating the effectiveness of this approach as part of a multimodal analgesia strategy. This case report suggests that such a technique, supervised by an anesthesiologist and supported by a multidisciplinary team, can provide effective postoperative pain control in PAD patients without interrupting perioperative anticoagulation. Formal protocols for similar procedures can arise, incorporating this analgesic option.
