Abstract

Objective: To investigate the incidence of delayed popliteal arteriovenous fistula after total knee arthroplasty. Methods: Twenty-four patients (30 knees) who had undergone total knee arthroplasty were retrospectively analyzed, and the diagnostic measures of delayed popliteal arteriovenous fistula after total knee arthroplasty were summarized. Results: One patient had swelling of the lower leg on the first day after operation, which was confirmed by Doppler ultrasound as gastrocnemius venous plexus thrombosis (distal thrombus), and no delayed popliteal arteriovenous fistula around the thigh was found. The swelling of limbs below groin occurred in 2 cases on the third day after operation, which was confirmed by Doppler ultrasound to form delayed iliac arteriovenous fistula. No case died of pulmonary embolism. Eight patients who only received anti-infection treatment were not effectively controlled after 8 weeks of treatment, and the patients showed signs of recurrence of infection; After debridement, 12 patients took out the prosthesis, and after anti-infection treatment, they were given knee replacement again, and the postoperative effect was good Infection was effectively controlled in 2 patients undergoing knee arthrodesis. Conclusion: The incidence of delayed popliteal arteriovenous fistula after total knee arthroplasty is high, so we should be alert to the occurrence of delayed popliteal arteriovenous fistula after total knee arthroplasty.
