A single-centre study of haemostatic outcomes of joint replacement in von Willebrand disease and control patients and an analysis of the literature

Bilateral total knee replacement for hemophilic arthropathy: a case report

Von Willebrand disease (vWD) and hemophilia present unique challenges in orthopedic surgery due to their inherent bleeding risks and potential complications. While joint bleedings are well-documented in hemophilia, they are less understood in vWD, especially regarding their impact on daily activities and the development of arthropathy. We present a case of a young female patient aged 25 years with vWD Type 3 who underwent bilateral total knee replacement (TKR) due to end-stage knee osteoarthritis. Following two previous operations of the right knee at the age of 14, the patient had high degree of extra-articular valgus and intra-articular deformity, ankylosed knee in 30o flexion, osteopenia, and chronic patellar dislocation. Bilateral TKR was performed using patient-specific templating (PST) technology, which includes preoperative planning using a CT scan followed by surgical execution. Financial constraints and limited prosthetic resources necessitated a sequential approach to TKR, addressing the more affected right knee first. Despite many challenges, successful outcomes were achieved, with significant improvements in pain, mobility, overall satisfaction, and no complications at two-year follow-up. Our case highlights the importance of individualized treatment strategies, meticulous surgical planning, and postoperative care in managing knee arthropathy patients with bleeding disorders.

Carpometacarpal Joint Arthroplasty in a Patient With Concomitant Von Willebrand Disease: A Case Report

Thumb carpometacarpal (CMC) joint osteoarthritis is characterized by severe pain, reduced grip strength, and restricted thumb mobility. This condition is among the most prevalent forms of arthrosis, significantly impacting patients' daily activities and overall quality of life. Managing patients with coagulation disorders presents a particular challenge, as they are at increased risk for postoperative bleeding, infectious complications, and the potential need for revision surgery. Von Willebrand disease (VWD) type I, a disorder caused by a deficiency of Von Willebrand factor (VWF), can lead to prolonged blood clotting times. This case report demonstrates the successful management of bilateral CMC joint osteoarthritis in a patient with VWD type I using arthroplasty, emphasizing the importance of perioperative hematological management to prevent complications.

Identification and optimisation of perioperative factors for patients with von Willebrand disease undergoing elective total hip and knee arthroplasty

Von Willebrand disease stands as the most prevalent bleeding disorder seen in both medical and surgical practice. Due to recurrent bleeding episodes within the joints, many patients endure arthropathy, leading to substantial pain and restricted function. Total joint arthroplasty emerges as a final option for managing such cases. Nevertheless, the existence of von Willebrand disease presents several challenges in this regard. This review aims to explore the perioperative strategies tailored for patients with von Willebrand disease undergoing elective total joint arthroplasty.

Outcomes Following Total Hip Arthroplasty in Patients Who Have Von Willebrand Disease Depend on Postoperative Anticoagulation

BACKGROUND

Von Willebrand disease (VWD) is the most common congenital bleeding disorder. This autosomal dominant condition arises from quantitative or qualitative defects of Von Willebrand factor. To our knowledge, this study leveraged a national database to characterize the largest VWD cohort of total hip arthroplasty (THA) patients to date, assessing 90-day postoperative adverse events and 5-year revision-free survival.

METHODS

Adult patients who underwent primary THA for osteoarthritis were identified from January 2010 to October 2021 in a nationwide database. Patients who had and did not have VWD were matched (4:1) on age, sex, and Elixhauser Comorbidity Index and compared with multivariable logistic regression. Patients were then categorized based upon venous thromboembolism (VTE) chemoprophylaxis prescription patterns to compare bleeding and thrombotic adverse events.

RESULTS

Of 544,851 THA patients, VWD was identified in 309 patients (0.06%). The matched cohorts contained 1,221 patients who did not have VWD and 306 patients who have VWD. On multivariable analysis, VWD patients had increased odds of 90-day VTE (odds ratio [OR] = 1.86) and hematoma (OR = 3.40) (P < .05 for all). No difference in 5-year revision-free survival was found. The VWD patients receiving aspirin or no prescriptions had greater odds of VTE (OR = 2.39, P = .048). Those on other chemoprophylaxis agents had greater odds of hematoma (OR = 4.84, P = .006).

CONCLUSIONS

Patients with VWD undergoing THA had increased odds of 90-day VTE if using aspirin or no prescriptions, or hematoma if using other chemoprophylaxis. There is a delicate balancing act of clotting versus bleeding that must be considered in managing such patients, but it was reassuring that no difference in overall 5-year revision-free survival was found.

Surgical management of patients with von Willebrand disease: summary of 2 systematic reviews of the literature

von Willebrand disease (VWD) is the most common inherited bleeding disorder. The management of patients with VWD who are undergoing surgeries is crucial to prevent bleeding complications. We systematically summarized the evidence on the management of patients with VWD who are undergoing major and minor surgeries to support the development of practice guidelines. We searched Medline and EMBASE from inception through October 2019 for randomized clinical trials (RCTs), comparative observational studies, and case series that compared maintaining factor VIII (FVIII) levels or von Willebrand factor (VWF) levels at >0.50 IU/mL for at least 3 days in patients undergoing major surgery, and those with options for perioperative management of patients undergoing minor surgery. Two authors screened and abstracted data and assessed the risk of bias. We conducted meta-analyses when possible. We evaluated the certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. We included 7 case series for major surgeries and 2 RCTs and 12 case series for minor surgeries. Very-low-certainty evidence showed that maintaining FVIII levels or VWF levels of >0.50 IU/mL for at least 3 consecutive days showed excellent hemostatic efficacy (as labeled by the researchers) after 74% to 100% of major surgeries. Low- to very-low-certainty evidence showed that prescribing tranexamic acid and increasing VWF levels to 0.50 IU/mL resulted in fewer bleeding complications after minor procedures compared with increasing VWF levels to 0.50 IU/mL alone. Given the low-quality evidence for guiding management decisions, a shared-decision model leading to individualized therapy plans will be important in patients with VWD who are undergoing surgical and invasive procedures.

Management of large volume liposuction in lipedema patients with von Willebrand disease: A systematic review and treatment algorithm

BACKGROUND

When performing large volume liposuction, perioperative management of lipedema patients with coagulation disorders remains challenging due to a lack of clinical experience. With a prevalence of 1% of von Willebrand disease (VWD) in the general population, basic knowledge on diagnostic and adapted surgical strategies are essential for patients' safety.

OBJECTIVE

Based on a selective literature review, the purpose of this article is to present a standardized algorithm for diagnosis and perioperative treatment of VWD patients undergoing large volume liposuction.

METHODS

The databases MEDLINE (via PubMed) and Web of Science were selectively searched with the term "(((liposuction) OR (surgery)) OR (lipectomy)) AND (((VWD) OR (hemostaseology)) OR (von Willebrand disease))". Included were articles published in English or German until November 2020.

RESULTS

The evidence for large volume liposuctions in patients with VWD is limited. Experience is largely based on operations with similar bleeding risks. A safe performance requires an adjustment of the surgical technique and a customized perioperative drug substitution plan. According to the current literature, perioperative thromboembolic events appear to be rare with adequate drug treatment.

CONCLUSION

The implementation of the developed diagnostic and treatment algorithm may help further reducing bleeding complications and improve the safety for treated patients.

ASH ISTH NHF WFH 2021 guidelines on the management of von Willebrand disease

BACKGROUND

von Willebrand disease (VWD) is a common inherited bleeding disorder. Significant variability exists in management options offered to patients.

OBJECTIVE

These evidence-based guidelines from the American Society of Hematology (ASH), the International Society on Thrombosis and Haemostasis (ISTH), the National Hemophilia Foundation (NHF), and the World Federation of Hemophilia (WFH) are intended to support patients, clinicians, and health care professionals in their decisions about management of VWD.

METHODS

ASH, ISTH, NHF, and WFH formed a multidisciplinary guideline panel. Three patient representatives were included. The panel was balanced to minimize potential bias from conflicts of interest. The University of Kansas Outcomes and Implementation Research Unit and the McMaster Grading of Recommendations Assessment, Development and Evaluation (GRADE) Centre supported the guideline development process, including performing and updating systematic evidence reviews (through November 2019). The panel prioritized clinical questions and outcomes according to their importance to clinicians and patients. The panel used the GRADE approach, including GRADE Evidence-to-Decision frameworks, to assess evidence and make recommendations, which were subject to public comment.

RESULTS

The panel agreed on 12 recommendations and outlined future research priorities.

CONCLUSIONS

These guidelines make key recommendations regarding prophylaxis for frequent recurrent bleeding, desmopressin trials to determine therapy, use of antiplatelet agents and anticoagulant therapy, target VWF and factor VIII activity levels for major surgery, strategies to reduce bleeding during minor surgery or invasive procedures, management options for heavy menstrual bleeding, management of VWD in the context of neuraxial anesthesia during labor and delivery, and management in the postpartum setting.

Do patients with von Willebrand disease exhibit higher blood loss and revision rates in hip and knee arthroplasty? A case-control study

BACKGROUND

The aim of the study was to compare the perioperative blood loss, need for transfusion and one-year revision rates in patients undergoing hip and knee arthroplasty who also have a diagnosis of von Willebrand disease (VWD) with a matched control group.

METHODS

A retrospective single-centre case-control study was conducted. Fifty-eight patients with VWD and 116 controls (1:2 match) who were operated for primary or revision hip and knee arthroplasty at our hospital were included. Blood loss, haemoglobin (Hb)-drop, need for blood transfusion, intraoperative complications and revision rates within one year were noted in all cases. Outcome measures for subgroups of the primary hip, primary knee, revision hip and revision knee procedures, were also analysed.

RESULTS

The mean perioperative Hb-drop was 3.47 (±1.27) g/dL and blood loss was 293 (±97) ml for the VWD group while Hb-drop was 2.85 (±1.21) g/dL and blood loss was 232 (±105) mL for the control group (P < .001). There were no significant increased transfusion rates (P = .264) and revision rates in the VWD group (P = .634). Patients having primary hip surgery had significantly higher Hb-drop (3.68 ± 1.25 g/dL vs 2.62 ± 1.19 g/dL; P = .003), higher blood loss (293 vs 203 mL; P = .002) and increased need for a transfusion (21% vs 2.6%; P = .038) compared to the controls. No outcome measure was found to be significantly different for primary and revision knee surgery.

CONCLUSIONS

The results of this study suggest that patients with VWD undergoing primary or revision total hip and knee arthroplasty have higher levels of blood loss than the control cohort. Perioperative protective measures including meticulous surgical techniques should be considered.

Management of von Willebrand disease in patients undergoing total hip and knee arthroplasty

Von Willebrand disease is the commonest bleeding disorder encountered in the medical and surgical field. As a result of the repetitive bleeding into the joints many patients suffer from arthropathy that can cause a significant amount of pain and functional limitation. Total joint arthroplasty is being utilised as the last resort in managing these patients; however, the presence of von Willebrand disease raises a number of dilemmas. In this review, we look at the effects of von Willebrand disease on joints and the perioperative management of von Willebrand disease patients undergoing total joint arthroplasty.
