Resection and total femoral prosthesis reconstruction treatment of massive femoral hemophilic pseudotumor: A case report.

Abstract

Introduction and importanceHemophilic pseudotumor is a rare and serious complication of hemophilia, often occurring in the long bones and muscle tissue of the extremities, with an incidence of about 1–2%. However, there is no effective surgical treatment for massive hemophilia pseudotumors of the extremities. Therefore, we would like to report this case to provide new ideas and methods for the treatment of massive hemophilic pseudotumors of the extremities through resection and total femoral prosthesis reconstruction.Case presentationAfter admission, the patient first underwent a month-long coagulation factor replacement therapy to maintain the patient's factor IX level at approximately 100%. Then, extensive resection of hemophilic pseudotumor and total femoral prosthesis reconstruction was performed in collaboration with several departments, and we collected the patient's preoperative, intraoperative and postoperative data for analysis.Clinical discussionAfter coagulation factor replacement therapy the patient's factor IX level was significantly increased and approached 100%. The surgical procedure was uneventful, and postoperative X-ray suggested a well-positioned prosthesis with postoperative pathological features consistent with a hemophilic pseudotumor. The patient was able to move around with the assistance of a walker 14 days after surgery, and there was no recurrence after one year of follow-up.ConclusionFor treat the massive hemophilic pseudotumors of the extremities, extensive resection and prosthetic replacement with coagulation factor replacement therapy is a safe and effective treatment that can significantly improve the prognosis and quality of life of patients.
