RESUMO

BACKGROUND: Reduction malarplasty is a routine clinical procedure among Asian women, but the traditional surgical methods are still associated with serious complications, such as nonunion of the osteotomy sites. Revisional surgery to correct such complications is common, but poor bone healing in the osteotomy area presents a challenge to plastic surgeons. In this report, the authors present a new technique for revision malarplasty that uses the piezosurgery (piezoelectric bone surgery) approach. PATIENT AND DIAGNOSIS: A 30-year-old female patient underwent reduction malarplasty with titanium plate fixation in the zygomatic region at another hospital 4 years ago, but the root of the zygomatic arch was not fixed. The patient was diagnosed with bone nonunion, facial asymmetry, and soft tissue sagging on the right side of the face after malarplasty. INTERVENTION: We used piezosurgery to truncate the displaced healed broken end of the zygomatic bone according to the original osteotomy line. Following this, the malar was re-fixed with micro-titanium mesh, and the zygomatic arch was fixed with a titanium plate. OUTCOME: The patient was followed up for 11 months after the revision procedure. Her facial appearance was satisfactory, and no complications were observed on computed tomography images. LESSONS: This report presents a novel therapeutic option for surgical revision of failed malarplasty. Piezosurgery can help overcome the limitations of traditional surgical methods by reducing bone resorption, preventing resorption of the bone in revision malarplasty, modifying the degree of inward and upward movement of the zygomatic bone by facilitating adjustment of the position of the drill hole in the cortex of the bone stump for stable fixation. Hence piezosurgery can be a simple, accurate, and non-invasive osteotomy method for revision malarplasty.

RESUMO

NATIONALE: Trichosporon species are widely distributed in nature and are emerging opportunistic human pathogens. Trichosporon infections are associated with superficial cutaneous involvement in immunocompetent individuals to severe systemic disease in immunocompromised patients. Until now, there is no report in infective endocarditis by Trichosporon mucoides confirmed by molecular diagnostics PATIENT CONCERNS:: A 66-year-old man presented with a fever that had occurred for a period of 6 months. He had undergone aortic valve replacement 10 years prior. Transthoracic echocardiography showed vegetations on the prosthetic aortic valve and native mitral valve. T mucoides was detected in the cultures of blood and vegetations. DIAGNOSIS: DNA sequencing using D/D2 region of rRNA and internal transcribed spacer were performed. INTERVENTIONS: Infections were successfully controlled with valve replacement and voriconazole plus liposomal amphotericin B therapy. OUTCOMES: There has been no sign of recurrence for 18-months after treatment completion. LESSONS: This is the first reported case of infective endocarditis due to T mucoides. Clinicians should consider Trichosporon species as causative agents of endocarditis in patients who have undergone cardiac surgery.

RESUMO

AIMS: The rate of dislocation when traditional single bearing implants are used in revision total hip arthroplasty (THA) has been reported to be between 8% and 10%. The use of dual mobility bearings can reduce this risk to between 0.5% and 2%. Dual mobility bearings are more expensive, and it is not clear if the additional clinical benefits constitute value for money for the payers. We aimed to estimate the cost-effectiveness of dual mobility compared with single bearings for patients undergoing revision THA. METHODS: We developed a Markov model to estimate the expected cost and benefits of dual mobility compared with single bearing implants in patients undergoing revision THA. The rates of revision and further revision were calculated from the National Joint Registry of England and Wales, while rates of transition from one health state to another were estimated from the literature, and the data were stratified by sex and age. Implant and healthcare costs were estimated from local procurement prices and national tariffs. Quality-adjusted life-years (QALYs) were calculated using published utility estimates for patients undergoing THA. RESULTS: At a minimum five-year follow-up, the use of dual mobility was cost-effective with an estimated incremental cost-effectiveness ratio (ICER) of between £3,006 and £18,745/QALY for patients aged < 55 years and between 64 and 75 years, respectively. For those aged > 75 years dual mobility was only cost-effective if the timeline was beyond seven years. The use of dual mobility bearings was cost-saving for patients aged < 75 years and cost-effective for those aged > 75 years if the time horizon was beyond ten years. CONCLUSION: The use of dual mobility bearings is cost-effective compared with single bearings in patients undergoing revision THA. The younger the patient is, the more likely it is that a dual mobility bearing can be more cost-effective and even cost-saving. The results are affected by the time horizon and cost of bearings for those aged > 75 years. For patients aged > 75 years, the surgeon must decide whether the use of a dual mobility bearing is a viable economic and clinical option. Cite this article: Bone Joint J 2020;102-B(9):1128-1135.

RESUMO

A 67-year-old woman was admitted with exertional dyspnea. She had undergone mitral valve replacement with Björk-Shiley prosthetic valve (convexo-concave type) 36 years previously for stenosis and regurgitation in another institute. An echocardiography showed a severe degree of aortic stenosis, and the implanted mitral valve function is normal. We performed aortic valve replacement with a bioprosthetic valve and no prophylactic reoperation for the implanted mitral valve. The postoperative courses were uneventful. The patient was discharged from the hospital in good clinical condition. Postoperative echocardiography showed the prosthetic valves were normal. The close follow-up should be needed to prevent fatal valve dysfunction.

RESUMO

A 66-year-old woman with primary antiphospholipid antibody syndrome (APS) was admitted due to severe dyspnea. Eight months prior to admission, she underwent bioprosthetic mitral valve replacement for mitral valve stenosis and regurgitation. Transthoracic echocardiogram showed thickening bioprosthetic valve leaflets and severe valve stenosis. Emergency reoperation for artificial valve failure was performed. The explanted bioprosthetic valve showed massive thrombus formation. After the operation, she started strict anticoagulant and antiplatelet therapies and was discharged without recurrence of valve thrombosis.

RESUMO

OBJECTIVE: To systematically evaluate the clinical efficacy of high-quality direct anterior approach (DAA) and other approaches for the treatment of elderly patients with femoral neck fracture. METHODS: Literatures published in English or Chinese about the direct anterior approach and other approaches for hemiarthroplasty in femoral neck fracture were searched on Cochrane Library, PubMed, EMBASE, Web of science, Wanfang, CNKI databases from their establishment to May 2019. According to the inclusion and exclusion criteria, two researchers independently screened the literatures, and extracted the data. The quality of RCT were evaluated by Cochrane Risk of Bias Assessment Tool, and non-RCT were evaluated by the NOS scale. Meta-analysis was performed using the RevMan 5.3 software. RESULTS: A total of 9 articles were included with 901 cases, in which 429 cases used DAA, and 472 used other approaches. DAA had a significantly lower dislocation rate compared to subgroup of posterior and posterolateral approach [OR=0.19, 95%CI (0.06, 0.61), P=0.005]. No significant differences were found between DAA group and subgroup of direct lateral and anterolateral approach[OR=1.08, 95%CI(0.20, 5.76), P=0.93]. Also there were no relevant differences between the DAA group and control in infection rate[OR=1.07, 95%CI(0.47, 2.43), P=0.88], perioperative fracture rate[OR=0.95, 95%CI(0.36, 2.50), P=0.92], re operation rate[OR=0.76, 95%CI(0.30, 1.89), P=0.55], overall complication rate [OR=0.88, 95%CI (0.63, 1.22), P=0.44], mortality [OR=1.33, 95%CI (0.84, 2.11), P=0.23], operative time[MD=1.43, 95%CI(-5.85, 8.71), P=0.70]. CONCLUSION: The current evidenceindicates that the DAA was associated with a significantly lower dislocation rate compared to posterior capsular approaches for hemiarthroplasty. There was no significant difference in dislocation rate with the lateral and anterolateral approach.

RESUMO

BACKGROUND: The German Arthroplasty Registry, EPRD, has the ability to examine early factors influencing the probability of failure of total hip arthroplasty (THA) and knee arthroplasty (TKA). The study analyses the influence of the overall experience of a hospital, as well as the change in supplier on the revision rate. MATERIALS AND METHODS: A total of 164,903 cementless THA and 155,577 cemented TKA were in follow-up from 656 hospitals from 2012 to 2019. The number of arthroplasties performed per hospital per year was used as a surrogate parameter for institutional experience. This number was subdivided into 250, 251-500 and more than 500 for hip and knee per year and the overall revision rate was analysed. Additionally, the effects of the change of a major supplier of implant systems to a hospital were analysed. At least 70% of the documented implant components for each calendar quarter were used in that hospital to define the company as a major supplier. RESULTS: The overall revision rate for THA was 3.9% for hospitals with up to 250 arthroplasties per year, 3.3% for hospitals with 251-500 arthroplasties per year and 2.9% for hospitals performing over 500 surgeries per year (p < 0.0001). The revision rate for TKA was also significantly different between the three groups with 3.4, 3.3 and 2.7% (p < 0.0001). Changing the supplier of implant systems also showed a significant increase of the revision rate (p < 0.0001 for THA, p = 0.02 for TKA). CONCLUSION: The institutional experience significantly influences short-term results in terms of the revision rate of hip and knee arthroplasty. Changing the implant system even in an experienced hospital has a major impact on the early revision rate and, therefore, needs careful transition.

RESUMO

OBJECTIVE: To report our own experience of one-stage surgical treatment of irradiation-induced osteomyelitis as a complication of radiotherapy for breast cancer (BC). MATERIAL AND METHODS: The study included 25 patients with irradiation-induced chest osteomyelitis after previous radiotherapy for breast cancer. All patients were examined according to the same protocol. One-stage surgery with full-thickness resection of affected tissues and plastic closure of the wound was performed depending on localization of lesion and availability of plastic material. RESULTS: Follow-up period ranged from 18 to 110 months (median 48 (19; 52) months). Complications were assessed according to Clavien-Dindo classification. Complications followed by antibacterial therapy and/or local treatment were observed in 8 (32%) out of 25 patients (95% CI 11.5-43.4). Marginal necrosis of musculoskeletal flap was registered in 4 (16%) patients. One (4%) patient required redo thoracomyoplasty after excision of necrotic tissues of musculocutaneous flap due to extensive tissue defect. Total necrosis of musculocutaneous flap was not noted. There were no fatal outcomes. Mean length of hospital-stay was 13 (10; 27) days in the group of musculocutaneous flap from latissimus dorsi muscle and 11 days (7; 24) in the group of rectus abdominis muscle. Good and satisfactory treatment outcomes after one-stage surgical treatment were achieved in 24 (96%) out of 25 patients (95% CI: 75-97.8). CONCLUSION: Irradiation-induced chest osteomyelitis is still actual problem despite an improvement of modern medical equipment and accumulation of experience in radiotherapy. Surgery is preferable method of treatment. Comprehensive examination including contrast-enhanced chest CT with 3D reconstruction and Doppler ultrasound of vascular pedicle is valuable to determine type of resection and plastic technique. Simultaneous approach with resection and plastic closure of the wound is preferred for irradiation-induced chest osteomyelitis if sufficient amount of plastic material is available and contraindications for reconstructive surgery are absent.

RESUMO

BACKGROUND: Plate fixation and intramedullary nail/Knowles pin fixation methods are commonly used to treat displaced midshaft clavicle fractures. However, the differences between these 2 methods are unclear. OBJECTIVE: This meta-analysis aimed to compare plate fixation and intramedullary nail/Knowles pin fixation for displaced midshaft clavicle fractures. METHODS: We searched PubMed, EBM reviews, and Ovid Medline online for studies related to comparison of plate fixation versus intramedullary nail/Knowles pin fixation for displaced midshaft clavicle fracture from inception to June 30, 2019. Relevant literature search, data extraction, and quality assessment will be performed by 2 researchers independently. The methodological quality of all included studies was appraised using the Cochrane system for randomized trials. The RevMan 5.2 software was used for heterogeneity assessment, generating funnel-plots, data synthesis, sensitivity analysis, and determining publication bias. The fixed-effects or random-effects model was used to calculate mean difference (MD)/relative risks (RRs) and 95% confidence intervals (CIs). RESULTS: This meta-analysis included 839 patients from 12 randomized controlled trials. We found that compared to plate fixation, intramedullary nail/Knowles pin fixation yielded a higher shoulder constant score [MD = -2.43, 95% CI (-3.46 to -1.41), P < .00001] and lower disabilities of the arm, shoulder and hand (DASH) score [MD = 2.98, 95% CI (0.16-5.81), P = .04], and lower infection rates [RR = 2.05, 95% CI (1.36-3.09), P = .003], operation time [MD = 20.20, 95% CI (10.80-29.60), P < .0001], incision size [MD = 6.09, 95% CI (4.54-7.65), P < .00001], and hospital stay [MD = 1.10, 95% CI (0.56-1.64), P < .00001] but with a higher removal rate [RR = 0.52, 95% CI (0.41-0.65), P < .00001] compared to plate fixation. There were no significant differences in nonunion, reintervention, or revision and refracture between these two methods. The limitation is that many studies did not demonstrate the random generated details, and only English articles were enrolled in this meta-analysis. CONCLUSIONS: Intramedullary nail/Knowles pin fixation might be an optimum choice for treating displaced midshaft clavicle fractures, with similar performance in terms of the nonunion, reintervention, or revision and refracture, and better shoulder constant and DASH scores, infection rates, and operative parameters.

RESUMO

BACKGROUND: There is limited evidence for the evaluation of the efficacy and safety of the hemiarthroplasty versus screw fixation in elderly patients with the displaced femoral neck fractures. Our current investigation aimed at assessing the complications, functional outcome, and revision rate of the patients (over 65 years old) who received internal fixation or hemiarthroplasty via a same senior surgeon. METHODS: A retrospective study was conducted on elderly patients with displaced femoral neck fractures from May 2014 to February 2018. The current study was carried out at our hospital and it was approved through our institutional review committee of West China Hospital. Inclusion criteria were as follows: the patients were 65 years or older, this is the anesthesia grade. The higher grade of the patients,the greater risk of surgery. level I-III, and the patients with displaced intracapsular fractures of the femoral neck, with the radiographic and clinical follow-up of 12 months or more. The major outcome was the revision rate between the 2 groups. And the secondary outcomes contained the life quality and functional outcome detected via utilizing the interview-administered and self-administered questionnaires, length of hospital stay, surgery time, and hip-related complications (such as hip dislocation, loosening or breakage of implant, wound problems, infection, osteolysis, neurovascular injury, and bone nonunion). RESULTS: It was assumed that hemiarthroplasty would result in fewer revisions or complications and better functional scores in comparison with internal fixation technique.

RESUMO

The present study is a retrospective cohort study. Metabolic syndrome (MetS) is a clustering of clinical findings that has been shown to increase the risk of the surgical outcomes. Our study aimed to evaluate whether MetS was a risk factor for increased perioperative outcomes in patients undergoing posterior lumbar interbody fusion (PLIF).We retrospectively analyzed patients over 18 years following elective posterior lumbar spine fusion from January 2014 to December 2018. Emergency procedures, infections, tumor, fracture, and revision surgeries were excluded. Patients were divided into 2 groups with and without MetS. The MetS was defined by having 3 of the following 4 criteria: obesity (body mass index ≥30 kg/m), dyslipidemia, hypertension, and diabetes. The follow-up period lasted up to 30 days after surgery. The outcomes of demographics, comorbidities, perioperative complications, and length of stay were compared between the 2 groups. Multivariate logistic regression analysis was used to identify perioperative outcomes that were independently associated with MetS.The overall prevalence of MetS was 12.5% (360/2880). Patients with MetS was a significantly higher risk factor for perioperative complications, and longer length of stay cmpared with patients without MetS (P < .05). The MetS group had a higher rate of cardiac complications (P = .019), pulmonary complication (P = .035), pneumonia (P = .026), cerebrovascular event (P = .023), urinary tract infection (P = .018), postoperative ICU admission (P = .02), and deep vein thrombosis (P = .029) than non-MetS group. The patients with MetS had longer hospital stays than the patients without MetS (22.16 vs 19.99 days, P < .001). Logistic regression analysis revealed that patients with MetS were more likely to experience perioperative complications (odds ratio [OR] 1.31; 95% confidence interval [CI]: 1.06-2.07; P < .001), and extend the length of stay (OR: 1.69; 95% CI: 1.25-2028; P = .001).The MetS is a significant risk factor for increased perioperative complications, and extend length of stay after PLIF. Strategies to minimize the adverse effect of MetS should be considered for these patients.

RESUMO

OBJECTIVE: The goal of this study was to review relevant studies in order to determine the efficacy of decompression with fusion versus decompression in the treatment of lumbar spinal stenosis. METHODS: Using appropriate keywords, we identified relevant studies using PubMed, the Cochrane library, and Embase. Key pertinent sources in the literature were also reviewed, and all articles published through October 2019 were considered for inclusion. For each study, we used odds ratios, mean difference (MD), and 95% confidence interval (95% CI) to assess and synthesize outcomes. RESULTS: We found 13 studies that were consistent with this meta-analysis with a total of 29066 patients. Compared with decompression, decompression with fusion significantly increased the incidence of complications (RR: 1.41, 95%CI: 1.26-1.57), the length of hospital stay (WMD: 1.868, 95%CI: 1.394-2.343), operative time (WMD: 80.399, 95%CI: 44.397-116.401), estimated blood loss (WMD: 309.356, 95%CI: 98.008-520.704) and Zurich claudication questionnaire in symptom severity (WMD: 0.200, 95%CI: 0.006-0.394). The reoperation rate was lower in the decompression with fusion group than the decompression group but without significant difference (RR: 0.91, 95%CI: 0.82-1.00). There was no significant difference between 2 groups in visual analog scale (leg pain and back pain), ODI, Short Form 36 Health Survey physical component summary, Short Form 36 Health Survey mental component summary, and Zurich claudication questionnaire physical function. CONCLUSION: Decompression with fusion has no significant clinical advantages in treatment of lumbar spinal stenosis when compared with decompression.

RESUMO

BACKGROUND/AIM: We conducted a randomized controlled trial to investigate whether minimally access spine surgery (MASS) is less morbid than open surgery (OS) in patients with metastatic spinal cord compression (MSCC). PATIENTS AND METHODS: A total of 49 MSCC patients were included in the trial. The outcome measures were bleeding (L), operation time (min), re-operations and prolonged wound healing. RESULTS: The median age was 67 years (range=42-85 years) and 40% were men. The peri-operative blood loss in the MASS-group was significantly lower than that in the OS-group; 0.175L vs. 0.500L, (p=0.002). The median operation time for MASS was 142 min (range=72-203 min) vs. 103 (range=59-435 min) for OS (p=0.001). There was no significant difference between the two groups concerning revision surgery or delayed wound healing. CONCLUSION: The MASS technique in MSCC patients is associated with less blood loss, but a longer operation time when compared to the OS technique.

RESUMO

AIMS: Hip resurfacing arthroplasty (HRA) is typically indicated for young and active patients. Due to the longevity of arthroplasty, these patients are likely to undergo revision surgery during their lifetime. There is a paucity of information on the long-term outcome of revision surgeries performed after failed HRA. The aim of our study was to provide survivorship data as well as clinical scores after HRA revisions. METHODS: A total of 42 patients (43 hips) were revised after HRA at our centre to a variety of devices, including four HRA and 39 total hip arthroplasties (THAs). In addition to perioperative complications, University of California, Los Angeles (UCLA) hip scores and 12-Item Short-Form Health Survey questionnaire (SF-12) quality of life scores were collected at follow-up visits after the primary HRA and after revision surgery. RESULTS: The mean follow-up time after revision surgery was 8.3 years (0.3 to 19.1). The mean UCLA pain and function scores post-revision were comparable with the best scores achieved by the patients after the index HRA, but UCLA activity scores were lower after revision. SF-12 physical component scores were comparable between timepoints, but the mental component score decreased after revision. Six patients underwent unilateral re-revision surgery at a mean follow-up time of 7.8 years (0.3 to 13.7). Using the time to any re-revision as endpoint, the Kaplan-Meier survivorship was 85.3% at 13 years. CONCLUSION: Patients undergoing revision after HRA can expect to achieve function and quality of life similar to their best after their primary surgery, while the risk of re-revision is low.

RESUMO

Recurrent instability and future joint damage occur if there is a repeated anterior cruciate ligament injury after reconstruction. This prognostic declaration is said to those who have sustained a rupture to the repaired anterior cruciate ligament. Both younger and older patients seek stable knees to allow a return to stability and twisting activity without the risk of added joint damage. To achieve this goal, revision ligament surgery is needed.

RESUMO

BACKGROUND: This meta-analysis was performed to incorporate newly published, high-quality randomized controlled trials (RCTs) to determine the effects of cemented versus uncemented hemiarthroplasty for elderly patients with displaced fracture of the femoral neck. METHODS: The following electronic databases were extensively searched from the inception of the database through December 2018: EMBASE, Medline, the Cochrane Library, and Web of Science. RCTs focusing on the outcomes of cemented and uncemented hemiarthroplasty were reviewed and screened for eligibility. We used the Cochrane Collaboration's Review Manager Software to perform meta-analyses. Two independent reviewers extracted the data and assessed the study quality and bias risk through the Cochrane Collaboration tool. Use fixed effect model or random effect model to pooled data. Cochran's Q statistic was used to evaluate heterogeneity, and I statistic was used to quantify heterogeneity. RESULTS: Fifteen RCTs were enrolled (n = 3790) (uncemented hemiarthroplasty group = 1015; cemented hemiarthroplasty group = 1037) (mean age ranged from 70-85.3 years; all patients > 65 years). The meta-analysis showed that cemented hemiarthroplasty has a longer operating time (weighted mean difference, 8.03; 95% confidence interval (CI) 4.83-11.23; P < .00001), less pain (odds ratio, 0.48; 95% CI 4.83-11.23; P = .02), lower mortality 1-year (odds ratio, 0.78; 95% CI 0.62-0.98; P = .03) and fewer implant-related complications (odds ratio, 0.20; 95% CI 0.13-0.30; P < .00001) than Uncemented hemiarthroplasty. However, there are still some limitations in our study, such as the uniformity of the surgery administration programme and rehabilitation scheme, and the small sample size of the included studies. CONCLUSIONS: Cemented hemiarthroplasty for elderly patients with displaced fracture of femoral neck may acquire better functional results.

RESUMO

To compare the surgical outcomes of medial rectus advancement and lateral rectus recession in postoperative consecutive exotropia with single-stage adjustable suture surgery.Among 1003 patients who underwent bilateral medial rectus recession between November 1996 and March 2013, the patients who required surgery for consecutive exotopia were retrospectively reviewed. Nineteen patients underwent medial rectus advancement and 15 patients underwent lateral rectus recession. All patients underwent single-stage adjustable surgery under topical anesthesia and were followed up for at least 12 months.The mean follow-up duration was 2.4 years. At final follow-up, a successful surgical outcome was found in 12 patients (63.0%) in the medial rectus advancement group and 14 patients (93.3%) in the lateral rectus recession group (P = .039). The change in ocular deviation was correlated with the amount of recession (P = .008) and preoperative angle (P < .001) in the lateral rectus recession group.Lateral rectus recession showed a higher success rate with predictable and easily performed procedure than medial rectus advancement for the treatment of postoperative consecutive exotropia with adjustable suture.

RESUMO

BACKGROUND: Patients treated for non-squamous (non-Sq) non-small cell lung cancer (NSCLC) often require repeat biopsies to determine the optimal subsequent treatment. However, the differences between rebiopsy and initial biopsy in terms of their diagnostic yields and their ability to test the molecular profiles using bronchoscopy with radial endobronchial ultrasound guidance in patients with advanced NSCLC remain unclear. Hence, we aimed to compare the diagnostic yields and ability for molecular analyses of rebiopsies with those of initial biopsies. METHODS: We investigated 301 patients with advanced non-Sq NSCLC who underwent radial endobronchial ultrasound-guided transbronchial biopsy (TBB) for peripheral pulmonary lesions (PPLs) between August 2014 and July 2017. Patients were divided into the rebiopsy and initial biopsy groups: the latter referred to the biopsy that determined the definitive diagnosis. The diagnostic yields and ability for molecular analyses were compared between the two groups, and the factors affecting the TBB diagnostic yield were identified using univariate and multivariate analyses. RESULTS: The diagnostic yields of the rebiopsy and initial biopsy groups were comparable (86.8 and 90.8%, respectively; p = 0.287). Furthermore, 93.0 and 94.0% of the patients in the rebiopsy and initial biopsy groups, respectively, had adequate specimens for gene profiling and mutational analysis (p = 0.765). The factors that increased the diagnostic yield were a positive bronchus sign (p < 0.001) and tumour location within the internal two-thirds of the lungs (p = 0.026). CONCLUSIONS: The PPL diagnostic yield of the rebiopsy group was as high as that of the initial biopsy group. Hence, TBB for PPLs is feasible for patients requiring rebiopsy as well as for those with initial diagnoses. Adequate, high-quality biopsy specimens can be obtained by transbronchial rebiopsy for molecular testing.

RESUMO

BACKGROUND: The optimal role of radial artery grafts in coronary artery bypass grafting (CABG) remains uncertain. The purpose of this study was to examine angiographic and clinical outcomes following CABG among patients who received a radial artery graft. METHODS: Patients in the angiographic cohort of the PREVENT-IV trial were stratified based upon having received a radial artery graft or not during CABG. Baseline characteristics and 1-year angiographic and 5-year clinical outcomes were compared between patients. RESULTS: Of 1,923 patients in the angiographic cohort of PREVENT-IV, 117 received a radial artery graft. These patients had longer surgical procedures (median 253 vs 228 minutes, P < .001) and had a greater number of grafts placed (P < .0001). Radial artery grafts had a graft-level failure rate of 23.0%, which was similar to vein grafts (25.2%) and higher than left internal mammary artery grafts (8.3%). The hazard of the composite clinical outcome of death, myocardial infarction, or repeat revascularization was similar for both cohorts (adjusted hazard ratio 0.896, 95% CI 0.609-1.319, P = .58). Radial graft failure rates were higher when used to bypass moderately stenotic lesions (<75% stenosis, 37% failure) compared with severely stenotic lesions (≥75% stenosis, 15% failure). CONCLUSIONS: Radial artery grafts had early failure rates comparable to saphenous vein and higher than left internal mammary artery grafts. Use of a radial graft was not associated with a different rate of death, myocardial infarction, or postoperative revascularization. Despite the significant potential for residual confounding associated with post hoc observational analyses of clinical trial data, these findings suggest that when clinical circumstances permit, the radial artery is an acceptable alternative to saphenous vein and should be used to bypass severely stenotic target vessels.

RESUMO

BACKGROUND: Patients aged ≥80 years are often treated with new-generation drug-eluting stents (DES), but data from randomized studies are scarce owing to underrepresentation in most trials. We assessed 1-year clinical outcome of octogenarians treated with new-generation DES versus younger patients. METHODS: We pooled patient-level data of 9,204 participants in the TWENTE, DUTCH PEERS, BIO-RESORT, and BIONYX (TWENTE I-IV) randomized trials. The main clinical end point was target vessel failure (TVF), a composite of cardiac death, target vessel-related myocardial infarction (MI), or clinically indicated target vessel revascularization. RESULTS: The 671 octogenarian trial participants had significantly more comorbidities. TVF was higher in octogenarians than in 8,533 patients <80 years (7.3% vs 5.3%, hazard ratio [HR]: 1.36, 95% CI: 1.0-1.83, P = .04). The cardiac death rate was higher in octogenarians (3.9% vs 0.8%, P < .001). There was no significant between-group difference in target vessel MI (2.3% vs 2.3%, P = .88) and repeat target vessel revascularization (1.9% vs 2.8%, P = .16). In multivariate analyses, age ≥ 80 years showed no independent association with TVF (adjusted HR: 1.04, 95% CI: 0.76-1.42), whereas the risk of cardiac death remained higher in octogenarians (adjusted HR: 3.38, 95% CI: 2.07-5.52, P < .001). In 6,002 trial participants, in whom data on major bleeding were recorded, octogenarians (n = 459) showed a higher major bleeding risk (5.9% vs 1.9%; HR: 3.08, 95% CI: 2.01-4.74, P < .001). CONCLUSIONS: Octogenarian participants in 4 large-scale randomized DES trials had more comorbidities and a higher incidence of the main end point TVF. Cardiac mortality was higher in octogenarians, whereas there was no increase in MI or target vessel revascularization rates. Treatment of octogenarian patients with new-generation DES appears to be safe and effective.
