Use of Topical Tranexamic Acid Reduces Direct and Indirect Blood Loss and Transfusion Rates in Revision Total Hip Arthroplasty.

ABSTRACT:

Background

In primary total hip arthroplasty (THA), evidence supports the use of tranexamic acid (TXA) as an effective strategy for reducing blood loss, but scant evidence supports its use in revision THA.

Questions/purposes

We aimed to evaluate whether the use of topical TXA in revision THA is associated with less blood loss and lower transfusion rates and to assess its safety, specifically as it relates to thromboembolic complications.

Methods

In this retrospective comparative study, two groups who underwent revision THA between 2005 and 2017 were defined: 98 patients who received 3 g of topical TXA (study group) and 475 patients who did not receive TXA (control group). Subjects were divided into subgroups according to the type of revision. Hemoglobin and hematocrit levels, blood loss, and transfusions were recorded. The follow-up period was 6 weeks.

Results

Median estimated blood loss, hidden blood loss, hemoglobin drop, and transfusion rates were significantly lower in the study group. The rates of post-operative thromboembolism were similar in the two groups. According to subgroup analysis, patients with revision of the femoral component, both components, and staged exchange revisions showed significantly lower rates of transfusion.

Conclusion

Topical TXA administration during revision THA effectively reduced direct and indirect blood loss, including hidden losses, without increasing the rates of thromboembolic events. This effect appeared to be enhanced when the femoral component was revised.

Topical tranexamic acid reduces blood loss and transfusion rates in total hip and total knee arthroplasty.

Project description:The objective of this study was to determine if tranexamic acid (TXA) applied topically reduced postoperative bleeding and transfusion rates after primary total hip arthroplasty (THA) and primary total knee arthroplasty (TKA). Two hundred and ninety consecutive patients from a single surgeon were enrolled. In TKA, TXA solution was injected into the knee after closure of the arthrotomy. In THA, the joint was bathed in TXA solution at three points during the procedure. In both THA and TKA the TXA solution was at a concentration of 3 g TXA per 100 mL saline. The mean blood loss was significantly higher in the non-TXA patients in both TKA and THA groups. Postoperative transfusions decreased dramatically with TXA, dropping from 10% to 0%, and from 15% to 1%, in the TKA and THA groups, respectively. Topical application of TXA significantly reduces postoperative blood loss and transfusion risk in TKA and THA.

Topical Tranexamic Acid Reduces Blood Loss in Minimally Invasive Total Knee Arthroplasty Receiving Rivaroxaban.

Project description:It is unclear whether topical (intra-articular) or intravenous TXA reduces blood loss in minimally invasive TKA patients receiving a direct oral anticoagulant for thromboprophylaxis. This study is to investigate whether TXA given intravenously or intra-articularly is effective in reducing blood loss in minimally invasive TKA patients using rivaroxaban for thromboprophylaxis.Ninety-three patients who underwent primary minimally invasive TKA were divided into placebo group (30 patients) that received saline both intravenously and intra-articularly, intravenous (IV) group (31 patients) that received 1?g TXA intravenously, and topical group (32 patients) that received 3?g TXA in 100?ml saline intra-articularly. All patients received oral rivaroxaban of 10?mg daily for 14 days postoperatively.p < 0.001 and p = 0.041. The mean total blood loss was 1131?mL (567-1845) in placebo, which was higher than that in the IV group (921?mL; range, 465-1495; p = 0.014) and the topical group (795?mL; range, 336-1350; p < 0.001). The total blood loss did not differ between the IV and the topical group (p = 0.179).This prospective, randomized, controlled trial demonstrated an equal efficacy of TXA in blood conservation when administered intravenously or topically in minimally invasive TKA patients receiving rivaroxaban for thromboprophylaxis.

Population-based rates of revision of primary total hip arthroplasty: a systematic review.

Project description:BackgroundMost research on failure leading to revision total hip arthroplasty (THA) is reported from single centers. We searched PubMed between January 2000 and August 2010 to identify population- or community-based studies evaluating ten-year revision risks. We report ten-year revision risk using the Kaplan-Meier method, stratifying by age and fixation technique.ResultsThirteen papers met the inclusion criteria. Cemented prostheses had Kaplan-Meier estimates of revision-free implant survival of ten years ranging from 88% to 95%; uncemented prostheses had Kaplan-Meier estimates from 80% to 85%. Estimates ranged from 72% to 86% in patients less than 60 years old and from 90 to 96% in older patients.ConclusionData reported from national registries suggest revision risks of 5 to 20% ten years following primary THA. Revision risks are lower in older THA recipients. Uncemented implants may have higher ten-year rates of revision, regardless of age.

Is topical or intravenous tranexamic acid preferred in total hip arthroplasty? A randomized, controlled, noninferiority clinical trial.

Project description:PURPOSE:The present study aimed to confirm the efficacy and safety of topical and intravenous tranexamic acid (TXA) compared with that of topical placebo and to assess the noninferiority between the two application methods of TXA in patients undergoing unilateral primary total hip arthroplasty. METHODS:Our randomized controlled trial investigated 170 patients with 1:1:1 allocation to two doses of 10-mg/kg intravenous TXA, 3-g topical TXA, and topical placebo of 60-ml physiological saline groups. The primary outcome, total blood loss, was calculated with Nadler and Gross formula. The secondary outcomes included allogeneic blood transfusion requirement, drain blood loss, decreased hemoglobin level. Noninferiority would be established when the upper limit 95% CI is lower than 250 ml of the noninferiority margin for the mean difference of total blood loss between topical and intravenous TXA. Thromboembolic complication incidence was considered as a safety outcome. RESULTS:The total blood loss of patients administered intravenous (mean±standard deviation, 1125±514 ml) and topical TXA (1211±425 ml) was significantly reduced compared with that of those administered topical placebo (1464±556 ml) (p = 0.0012). Drain blood loss and hemoglobin level reduction in patients administered with TXA were also significantly lower than those in patients administered topical placebo. The mean difference of total blood loss between topical and intravenous TXA is 86 ml (95% CI, -88 to 260 ml). The complications were comparable between patients managed with TXA and patients with topical placebo. CONCLUSION:The noninferiority of topical TXA to intravenous TXA can not be concluded. Considering no significant difference was found in all efficacy outcomes between the two administration methods. Any of the two TXA administration methods can be adopted for blood loss prevention in total hip arthroplasty.

Revision of a Tronzo Total Hip Arthroplasty.

Project description:Revision total hip arthroplasty presents many challenges in regards to reconstructing or managing large amounts of bone loss and soft-tissue damage. Modern revision components, as well as techniques, have helped to address these challenges; however, the goal of any surgery is to provide the least amount of surgery with the most successful outcome. This case highlights a 74-year-old man with a Tronzo total hip arthroplasty placed over 50 years prior. He presented with subjective hip instability and radiographs demonstrating disassociation of the modular component. In an attempt to avoid more extensive and costly surgery, a custom-made all-polyethylene femoral head was used. This case illustrates the revision of likely one of the few Tronzo total hips remaining and the utility of obtaining a compassionate-use clearance from the Food and Drug Administration to create a custom piece, to minimize potential morbidity and mortality from extensive hip revision surgery.

Revision total hip arthroplasty for metal-on-metal failure.

Project description:Metal-on-metal (MoM) arthroplasty systems became popular in the early-2000s due to presumed advantages of improved wear characteristics and superior stability. However, subsequent reports of abnormal soft-tissue reactions to MoM implants and national registry data reporting high failure rates raised concerns. Early outcomes of revision total hip arthroplasty (THA) for adverse reaction to metal debris (ARMD) were poor, leading to development of surveillance programs and a trend towards early revision surgery. Patients with MoM arthroplasties require surveillance, comprehensive history and physical examination, imaging with ultrasound or magnetic resonance imaging (MRI), and laboratory evaluation including metal ion levels. Operative strategies for revision THA vary from exchange of modular components to extensive debridement and reconstruction with revision components. Surgeons should be aware of the increased risks of dislocation and infection following revision THA for ARMD. However, there is growing evidence that early revision surgery prior to extensive soft tissue destruction results in improved outcomes and decreased re-operation rates. It is estimated that >1 million MoM articulations have been implanted, with a large proportion still in situ. It is imperative to understand the aetiology, presentation, and management strategies for these patients to optimise their clinical outcomes.

Occlusion of an Aortobifemoral Graft after Revision Total Hip Arthroplasty.

Project description:With the aging population, the demand for total hip arthroplasty is rising. Improvements in arthroplasty techniques and design allow for total hip arthroplasty to be increasingly performed in older patients and those with multiple comorbidities. Complications are rare in young and healthy patients; however, there is greater risk in patients with multiple medical comorbidities and those who have had prior revision procedures. Large-vessel thrombosis is an especially rare, but potentially devastating, complication, particularly in patients with existing major-vessel bypass grafts. Only 3 case reports of major-vessel graft occlusion after total hip arthroplasty have been reported in the literature, and none after revision. In this article, we report a case of occlusion of an aortobifemoral graft after revision total hip arthroplasty for periprosthetic joint infection.

Left Profunda Femoral Artery Pseudoaneurysm After Revision Total Hip Arthroplasty.

Project description:We present a case report of an 84-year-old male who presented with a profunda femoris artery (PFA) pseudoaneurysm 8 years after the index revision total hip arthroplasty procedure. Failure of revision hardware and subsequent migration of implants led to damage of the PFA and pseudoaneurysm formation. The patient was hemodynamically unstable on presentation and required emergent endovascular intervention. Once medically stabilized, the patient underwent extensive debridement of the aneurysm and hematoma bed and broken hardware was removed to prevent further complications. At 6-month follow-up, the patient was able to mobilize independently and had returned to all prior levels of activities of daily living. We discuss the vascular anatomy of the hip, the paucity of literature on PFA pseudoaneurysm, as well as the likely etiology of total hip arthroplasty failures.

Preoperative optimization for vascular involvement complicating revision total hip arthroplasty.

Project description:Vascular complications in revision total hip arthroplasty may occur in cases where the components of the hip implant migrate through the acetabular wall, through the iliopectineal line of the pelvis, and into the pelvic cavity. This migration may lead to substantial intrapelvic vascular compromise, drastically increasing the surgical complexity and potential risk for morbidity and mortality in these surgical cases. Here, we present a case of a 78-year-old woman with significant acetabular protrusio, which resulted in intraoperative compromise of the external iliac artery with rapid extravasation. As a result of prudent preoperative planning, interdisciplinary collaboration, and precautionary measures, significant patient morbidity and mortality was averted.Level of evidenceLevel V, Case Report.
