Total hip arthroplasty in patients with haemophilia - What are the risks of bleeding in the immediate peri-operative period?

Total Hip Replacement in Severe Haemophilia A: Challenges and Feasibility

The management of haemophilic patients is complicated due to multiple comorbidities. A dedicated haemophilia treatment centre with a multidisciplinary team can plan and execute elective orthopaedic surgery in such haemophilic individuals. A cementless total hip arthroplasty (THA) was performed in a 26-year-old male patient with haemophilic arthropathy of the right hip under factor VIII replacement therapy based on activated partial thromboplastin time levels. The patient received a preoperative dose of recombinant anti-haemophilic factor. Venous thromboembolic event prophylaxis was not given. Postoperative radiographs demonstrated successful prosthesis placement. The patient could bear weight and walk unassisted two weeks after surgery. THA in patients with haemophilia leads to significant improvement in joint function with a relatively low incidence of complications with modern techniques and haematological management.

Perioperative haematological outcomes following total knee arthroplasty in haemophiliacs

PURPOSE

Patients with haemophilia suffer from recurrent joint haemarthrosis. This can progress to symptomatic arthropathy commonly affecting the knee. While modern coagulation strategies have reduced those proceeding to end-stage arthropathy, total knee arthroplasty (TKA) remains the optimal treatment for some patients. Despite innovation in perioperative haematological management, concerns about the potential for excessive haemorrhage still exist. The aim of this study is to quantify immediate postoperative blood loss and haematological complications in haemophiliacs following TKA.

METHODS

A retrospective study of patients with haemophilia types A or B who underwent a TKA over a 12-year period at a single institution was conducted. These patients were compared to both a non-haemophiliac control group and to published standards in non-haemophiliacs undergoing TKA.

RESULTS

Twenty-one TKA procedures in 18 patients (72% haemophilia A, 28% haemophilia B) were suitable for inclusion with a mean age of 44 years. The mean haemoglobin drops at 24 and 48 h postoperatively were 2.7 g/dl and 3.8 g/dl respectively. There was no significant difference in haemoglobin drop at 48 h postoperatively when compared to the non-haemophiliac control group (P = 0.2644). There were no immediate perioperative complications and two patients (9.6%) required postoperative transfusion.

CONCLUSION

Haemophiliacs undergoing a unilateral primary TKA in a specialised tertiary referral centre appear to have comparable rates of perioperative blood loss when compared to both a non-haemophiliac control group as and published haemostatic standards in non-haemophiliac patients following TKA. Perioperative management with expert orthopaedic and haematological input is recommended to optimise outcomes in this complex patient group.

Thrombotic activation before and after total hip arthroplasty. A prospective cohort study

Background

Total hip arthroplasty (THA) causes acute blood loss. It may lead to a deficiency in coagulation factors, which, in turn, may lead to increased bleeding during the postoperative period.

Methods

Thirty patients (18 women) with a mean age of 67 years (range: 63–72 years) participated in this prospective diagnostic study. THA was performed without tranexamic acid administration in the perioperative period. Activities of clotting factors II, VIII, X, and fibrinogen concentration were evaluated before surgery, 6 hours after the procedure, 2, 4, and 6 days after the operation. All laboratory tests were performed using ACL TOP 500 CTS analyzer.

Results

No thromboembolic complications were noted during hospitalization. Mean fibrinogen concentration was 366 mg/dL before surgery, which decreased to 311 mg/dL 6 hours after the operation and peaked at 827 mg/dL on the 4th day after the procedure. Activities of factors II and X decreased on the second and fourth days after surgery. Although the activity of factor VIII decreased after the procedure, it remained within the normal range. Increased baseline fibrinogen concentrations were observed in 6 out of 30 (20%) patients. Mean blood loss was 1332 mL (range, 183–2479 mL) and did not correlate with changes in clotting factor activities.

Conclusions

In patients undergoing THA, fibrinogen acts as an acute-phase protein. Activities of clotting factors II and X normalize within 6 days, and although the activity of factor VIII decreases, it remains within the normal range.
