title: Saphenous neuralgia: a complication of vascular reconstructions below the inguinal ligament.
abstract: Although relatively frequent in our experience saphenous neuralgia (SN) is not usually reported as a complication of vascular operations below the inguinal ligament. In 55 patients undergoing extended deep femoral angioplasty (EDFA, n = 28) and femoropopliteal bypass graft (FPBG, n = 27) special attention was paid to incidence and severity of postoperative SN. Severe early postoperative SN was seen in 8/28 patients with EDFA and in 6/27 with FPBG. Milder SN was seen in 10 more patients with EDFA, and 3 other developed SN many months after surgery. The milder forms of SN and late SN were not encountered after FPBG. SN usually improved with the passage of time, and at last follow-up averaging 18 months for EDFA and 33 months for FPBG there remained only 23 patients with mild SN (15 after EDFA and 8 after FPBG). The etiology of SN appears to be trauma to the nerve sustained during operation. Age, sex, diabetes, or the addition of lumbar sympathectomy to the vascular operation did not affect the risk of sustaining early postoperative SN. Increased awareness of this complication may help to understand its pathophysiology better, and possibly to decrease its incidence.
