ABSTRACT

AIMS: We aimed to compare the long-term outcomes of patients undergoing percutaneous coronary intervention (PCI) with biodegradable polymer drug-eluting stents (BP-DES) versus durable polymer drug-eluting stents (DP-DES). METHODS AND RESULTS: Among 11 517 PCIs with second-generation DES performed in our institution between 2007 and 2019, we identified 8042 procedures performed using DP-DES and 3475 using BP-DES. The primary outcome was target lesion failure, the composite target lesion revascularization (TLR), target vessel myocardial infarction and death. Propensity score matching was used to create a well-balanced cohort. Mean follow-up was 4.8 years. Of the 3413 matched pairs, 21% were females, and the mean age was 66 years. At 1 year, the primary outcome occurred in 8.3% patients versus 7.1% (P = 0.07), and TLR rate was 3% versus 2% (P = 0.006) in patients with DP-DES and BP-DES respectively. Within 5 years, the primary outcome occurred in 23.1% versus 23.4% (P = 0.44), and the rate of TLR was 7.2% versus 6.5% (P = 0.07) in patients with DP-DES and BP-DES, respectively. CONCLUSION: Similar rates of the composite outcome were observed throughout the entire follow-up. Target lesion revascularization rates were lower in the BP-DES group at 1-year but equalized within 5 years.

ABSTRACT

BACKGROUND: Ultrathin bioresorbable polymer sirolimus-eluting stents (BP-SESs) may easily lead to acute recoil. This study investigated acute recoil after BP-SES implantation on the basis of intravascular ultrasound (IVUS). METHODS: We enrolled 40 consecutive stents. Absolute acute recoil by quantitative coronary angiography was defined as the difference between the mean diameter of the last inflated balloon (X) and mean lumen diameter of the BP-SES immediately after balloon deflation (Y). Percent (%) acute recoil was defined as (X-Y)×100/X. IVUS was performed within the culprit lesion. Plaque eccentricity, % plaque burden and calcification grade score were assessed using IVUS. Calcification grade was scored on the basis of quadrants. On the basis of the median acute recoil value of 5.0%, the stents were divided into two groups: low (LAR, n = 20) and high % acute recoil (HAR, n = 20). RESULTS: Mean % acute recoil was 5.8 ± 5.3%. Plaque eccentricity, % plaque burden and stent/artery ratio were significantly higher in the HAR group than in the LAR group. Significant differences in % acute recoil were not observed regarding the types of stent diameter. In multivariate logistic regression and multiple linear regression analysis, plaque eccentricity and % plaque burden in the culprit plaque were significant positive predictors for the occurrence of % acute recoil. No significant differences, including clinical outcomes, were found between both groups at follow-up. CONCLUSION: Acute recoil of BP-SESs may be influenced by an eccentric plaque with a large burden, which did not affect long-term outcomes. However, the present study might suggest the proper strategy (e.g. a more exhaustive plaque preparation) before BP-SES implantation in a case with these IVUS characteristics.

ABSTRACT

A recent thinner strut drug-eluting stent might facilitate early strut coverage after its placement. We aimed to investigate early vascular healing responses after the placement of an ultrathin-strut bioresorbable-polymer sirolimus-eluting stent (BP-SES) compared to those with a durable-polymer everolimus-eluting stent (DP-EES) using optical coherence tomography (OCT) imaging.This study included 40 patients with chronic coronary syndrome (CCS) who underwent OCT-guided percutaneous coronary intervention (PCI). Twenty patients each received either BP-SES or DP-EES implantation. OCT was performed immediately after stent placement (baseline) and at 1-month follow-up.At one month, the percentage of uncovered struts reduced significantly in both the BP-SES (80.9 ± 10.3% to 2.9 ± 1.7%; P < 0.001) and DP-EES (81.9 ± 13.0% to 5.7 ± 1.8%; P < 0.001) groups, and the percentage was lower in the BP-SES group than in the DP-EES group (P < 0.001). In the BP-SES group, the percentage of malapposed struts also decreased significantly at 1 month (4.9 ± 3.7% to 2.6 ± 3.0%; P = 0.025), which was comparable to that of the DP-EES group (2.5 ± 2.2%; P = 0.860). The optimal cut-off value of the distance between the strut and vessel surface immediately after the placement to predict resolved malapposed struts was ≤ 160 µm for BP-SES and ≤ 190 µm for DP-EES.Compared to DP-EES, ultrathin-strut BP-SES demonstrated favorable vascular responses at one month, with a lower rate of uncovered struts and a comparable rate of malapposed struts.

ABSTRACT

Hyperglycemia is an important risk factor for poor clinical outcomes in patients with acute myocardial infarction (AMI). The relative superiority of the long-term clinical outcomes of durable-polymer (DP) -based and biodegradable-polymer (BP) -based newer-generation drug-eluting stents (DESs) after successful percutaneous coronary intervention (PCI) in patients with AMI and prediabetes is not well established. We compared the clinical outcomes in such patients between DP-based and BP-based newer-generation DESs.A total of 4,377 patients with AMI and prediabetes were divided into the following two groups: the DP-DES group (n = 3,775; zotarolimus-eluting stents [ZES; n = 1,546] and everolimus-eluting stents [EES; n = 2,229]) and the BP-DES group (n = 602; biolimus-eluting stents [BES]). The primary endpoint was the occurrence of major adverse cardiac events (MACEs), defined as all-cause death, recurrent myocardial infarction (re-MI), or any repeat revascularization. The secondary endpoint was the occurrence of stent thrombosis (ST).The 2-year adjusted hazard ratio (aHR) of MACEs for ZES versus EES, ZES versus BES, EES versus BES, and ZES/EES versus BES (aHR: 1.125; 95% confidence interval [CI], 0.834-1.518; P = 0.440) were similar. The cumulative incidence of ST was also comparable between the DP-DES and BP-DES groups (aHR: 1.407; 95% CI, 0.476-4.158; P = 0.537). Moreover, the 2-year aHRs of all-cause death, CD, re-MI, target lesion revascularization (TLR), target vessel revascularization (TVR), and non-TVR were similar.Patients with AMI and prediabetes who received DP-DES or BP-DES during PCI showed comparable safety and efficacy during the 2-year follow-up period.

ABSTRACT

Clinical outcomes after percutaneous coronary intervention (PCI) for severely calcified lesions remain poor. The purpose of this study was to investigate the neointimal response after everolimus-eluting stents (EES) for severely calcified lesions treated with rotational atherectomy (RA) using optical coherence tomography (OCT).We retrospectively analyzed 34 lesions in which PCI was performed with EES deployment following RA and OCT was performed immediately after PCI and at follow-up (nine months). The EES was either durable-polymer (DP) EES (22 lesions) or bioabsorbable polymer (BP) -EES (12 lesions). Strut coverage and malapposition were evaluated at 1-mm intervals of cross-section (CS) by serial OCT analysis. Malapposed strut was defined as having the distance from luminal border > 100 µm.A total of 11,823 struts immediately after PCI and 11,720 struts at follow-up were analyzed. Immediately after PCI, the strut-level analysis showed no significant differences in the percentage of malapposed struts between the DP-EES group and the BP-EES group. At follow-up, the BP-EES group showed a more prevalent covered strut compared with the DP-EES group (strut-level analysis: 95% versus 97%, P = 0.045; CS-level analysis: 97% versus 100%, P < 0.01; lesion-level analysis: 27% versus 83%, P < 0.01, respectively).In severely calcified lesions requiring RA, the BP-EES group achieved better neointimal coverage than the DP-EES group at nine months. Additional prospective studies are needed.

ABSTRACT

BACKGROUND: The FLEX-LONG study assessed the safety and clinical outcomes of ultra-long (44 mm/48 mm) biodegradable polymer-coated Supraflex (Sahajanand Medical Technology Pvt. Ltd., Surat, India) sirolimus-eluting stents (SES) in real-world patients with complex, long coronary artery lesions. METHODS: It was an investigator-initiated, retrospective, non-randomized, observational and single-center study, which evaluated one-year results of 141 patients who had undergone implantation of at least one ultra-long (44 mm/48 mm) Supraflex SES. The incidence of major adverse cardiac events (MACE), a composite of cardiac death, myocardial infarction (MI) and target lesion revascularization (TLR), at one-year follow-up was considered as primary outcome. Stent thrombosis was analyzed as a safety outcome. RESULTS: The mean age of the study population was 56.2±9.6 years and 78.0% (110/141) patients were male. The study analyzed high risk patients, including 62 (44.0%) hypertensive and 60 (42.6%) diabetic patients. Total 147 target lesions were treated, including 25 (17.0%) total occlusions. Total 51 (34.7%) and 96 (65.3%) Supraflex SES of 44 mm and 48 mm were implanted, respectively. Average stent length and diameter were 46.6±1.9 mm and 3.4±0.2 mm, respectively. One-year follow-up was obtained in 100% of patients. There was one probable stent thrombosis after three weeks. At one-year follow-up, 99.3% of patients remained event free. CONCLUSIONS: The results of the FLEX-LONG study support the use of ultra-long (44 mm/48 mm) Supraflex SES, in the treatment of high-risk real-world patients. The stent appeared to be safe and effective at one-year with low clinical events in complex, long coronary artery lesions.

ABSTRACT

PURPOSE: Clinical performance of hernia mesh devices is poorly understood due to a lack of relevant clinical trial and real-world data (RWD). Registries offer a means to capture longitudinal data in real-world practice. This report highlights the need for data quality, completeness, and appropriate analysis methodology for more accurate and informed interpretation of RWE of medical devices. METHODS: Hernia mesh registry data were used to cross-tabulate the 30-day infection rate of patients who received one of four mesh types. RESULTS: Initial data review suggested lower infection rate for permanent mesh versus absorbable mesh. Additional registry RWD were factored into the analysis, providing more context in the interpretation of the results. CONCLUSIONS: High-quality registries can be used to generate real-world evidence (RWE) to support surveillance and other regulatory decisions.

ABSTRACT

Importance: Physicians have been criticized for having an overly enthusiastic response to new device approvals, especially for novel technologies. However, to our knowledge, the rates of new product adoption and patterns of new device usage in clinical practice have not been well described. Objective: To characterize the patterns of uptake of bioresorbable vascular scaffolds (BVS) within the United States following device approval and to describe changes in response to subsequent releases of data and US Food and Drug Administration (FDA) warnings. Design, Setting, and Participants: This analysis of the uptake of BVS between January 2016 and June 2017 used CathPCI Registry data; all percutaneous coronary intervention (PCI) procedures with an implant of either a BVS or conventional stent were included. Data analysis was performed in October 2017. Exposures: Implant of BVS. Main Outcomes and Measures: The primary outcome was monthly use of BVS in the United States. In addition, the characteristics of patients who received BVS and of hospitals that used BVS were assessed and comparisons of patient characteristics between BVS recipients and patients who were treated contemporaneously with metallic stents were made. Results: Of 682 951 procedures, 471 064 (69.0%) were done in men, 587 301 (86.0%) were among white people, and the mean (SD) age of those undergoing procedures with BVS vs conventional stents was 62.6 (11.4) years vs 65.7 (11.9) years. Of these, 4265 procedures (0.6%) used BVS overall (after FDA approval of BVS). Procedures with implants of BVS occurred among patients with fewer comorbidities and lower-acuity presentations compared with procedures with implants of conventional stents. The patient characteristics for BVS use were not dissimilar to the inclusion criteria of the ABSORB III FDA approval trial, with notable differences based on trial eligibility (eg, excluding patients with myocardial infarctions). The maximum monthly use of BVS was 1.25% of all PCI procedures that occurred 90 days after FDA approval, but with site-to-site variability. Declines in use were observed coincident with the scientific presentation of adverse event data as well as FDA warnings. Conclusions and Relevance: Most US physicians and hospitals were selective in their use of BVS, primarily using them in patients similar to those in the device's FDA approval trial. In addition, declines in use were evident in the subsequent month following the release of data that reported negative outcomes. These results illustrate an example of an appropriate physician response to adverse data updates and FDA warnings.

ABSTRACT

AIMS: Randomized clinical trials have consistently demonstrated the non-inferiority of bioabsorbable polymer drug-eluting stents (BP-DES) with respect to DES having permanent polymers (PP-DES). To date, the comparative performance of BP- and PP-DES in the real world has not been extensively investigated. METHODS AND RESULTS: From October 2011 to June 2016, we analysed the outcomes associated with newer generation DES use in Sweden. After stratification according to the type of DES received at the index procedure, a total of 16 504 and 79 106 stents were included in the BP- and PP-DES groups, respectively. The Kaplan-Meier estimates for restenosis at 2 years were 1.2% and 1.4% in BP- and PP-DES groups, respectively. Definite stent thrombosis (ST) was low in both groups (0.5% and 0.7% in BP- and PP-DES groups, respectively). The adjusted hazard ratio (HR) for either restenosis or definite ST did not differ between BP- and PP-DES [adjusted HR 0.95, 95% confidence interval (CI) 0.74-1.21; P = 0.670 and adjusted HR 0.79, 95% CI 0.57-1.09; P = 0.151, respectively]. Similarly, there were no differences in the adjusted risk of all-cause death and myocardial infarction (MI) between the two groups (adjusted HR for all-cause death 1.01, 95% CI 0.82-1.25; P = 0.918 and adjusted HR for MI 1.05, 95% CI 0.93-1.19; P = 0.404). CONCLUSION: In a large, nationwide, and unselected cohort of patients, percutaneous coronary intervention with BP-DES implantation was not associated with an incremental clinical benefit over PP-DES use at 2 years follow-up.

ABSTRACT

INTRODUCTION AND OBJECTIVES: There is little evidence on rates of stent thrombosis (ST) in patients receiving dual antiplatelet therapy (DAPT) with ticagrelor or prasugrel. The aim of this study was to analyze the incidence and predictors of ST after an acute coronary syndrome among patients receiving DAPT with ticagrelor vs prasugrel. METHODS: We used data from the RENAMI registry (REgistry of New Antiplatelet therapy in patients with acute Myocardial Infarction), analyzing a total of 4123 acute coronary syndrome patients discharged with DAPT with ticagrelor or prasugrel in 11 centers in 6 European countries. The endpoint was definite ST within the first year. A competitive risk analysis was carried out using a Fine and Gray regression model, with death being the competitive event. RESULTS: A total of 2604 patients received DAPT with ticagrelor and 1519 with prasugrel; ST occurred in 41 patients (1.10%), with a similar cumulative incidence between ticagrelor (1.21%) and prasugrel (0.90%). The independent predictors of ST were age (sHR, 1.03; 95%CI, 1.01-1.06), ST segment elevation (sHR, 2.24; 95%CI, 1.22-4.14), previous myocardial infarction (sHR, 2.56; 95%CI, 1.19-5.49), and serum creatinine (sHR, 1.29; 95%CI, 1.08-1.54). CONCLUSIONS: Stent thrombosis is infrequent in patients receiving DAPT with ticagrelor or prasugrel. The variables associated with an increased risk of ST were advanced age, ST segment elevation, previous myocardial infarction, and serum creatinine.

ABSTRACT

ABSTRACT Background: The surgical treatment of anal fistula is complex due to the possibility of fecal incontinence. Fistulotomy and cutting Setons have the same incidence of fecal incontinence depending on the complexity of the fistula. Sphincter-preserving procedures such as anal fistula plug and ligation of intersphincteric fistula tract procedure may result in more recurrence requiring repeated operations. The aim of this study was to evaluate and compare the outcomes of treating fistula in Ano utilizing two methods: Fistula plug (Gore Bio-A) and ligation of intersphincteric tract (LIFT). Methods: Fifty four patients (33 males; 21 female, median ages 42 [range 32-47] years) with high anal inter-transphenteric fistula were treated with LIFT and fistula plug procedures from September 2011 until August 2016 by a single surgeon and were retrospectively evaluated. All were followed for a median of 23.9 (range 4-54) months with clinical examination. Twenty one patients underwent fistula plug and 33 patients underwent LIFT procedure (4 patients of the LIFT group underwent LIFT and rectal mucosa advancement flap). The healing rate and complications were evaluated clinically and through telephone calls. Results: The mean operative time for the Plug was 25 ± 17 min and for the LIFT was 40 ± 20 min (p = 0.017) and the mean hospital stay was 2.4 ± 1.1 and 1.9 ± 0.3 (p = 0.01) respectively. The early complications of the plug and LIFT procedures included; anal pain (33.3%, 66.6%, p = 0.13), perianal discharge (77.8%, 91%, p = 0.62), anal pruritus (38.9%, 50.0%, p = 0.71) and bleeding per rectum (16.7%, 33.3%, p = 0.39) respectively. The overall mean follow-up was 20.9 ± 16.8 months, p = 0.68. There was no statistically significant difference between the two groups (21.9 ± 7.5 months, 19.9 ± 16.1 months, p = 0.682). The healing rate was 76.2% (16/21 patients) in the fistula plug group and 81.1% (27/33 patients) in the LIFT group (p = 0.73). Patients who had LIFT procedure and a mucosal advancement flap had 100% healing rate (4 out of 4 patients). No incontinence of stool or feces and no fistula plug expulsion were seen in our patients. The healing time ranged from 1 to 6 months after surgery. There was no post-operative perianal abscess, cellulitis or pain. Conclusions: LIFT and anal plug are safe procedures for patients with primary and recurrent anal fistula. Both techniques showed excellent results in terms of healing and complication rate. None of our patients had incontinence after 5 years follow-up. The best success rate in our patients was seen after LIFT procedure with mucosal advancement flap. Larger and controlled randomized trials are needed for better assessment of treatment options.


RESUMO Introdução: O tratamento cirúrgico da fístula anal é complexo devido à possibilidade de incontinência fecal. A fistulotomia e o seton de corte têm a mesma incidência da incontinência fecal, dependendo da complexidade da fístula. Procedimentos de preservação do esfíncter, como o tampão da fístula anal e o procedimento LIFT (ligadura do trato da fístula interesfincteriana), podem resultar em mais recorrência, exigindo cirurgias repetidas. O objetivo deste estudo foi avaliar e comparar os desfechos do tratamento da fístula anal utilizando dois métodos: Tampão de fístula (Gore Bio-A) e Ligadura do Trato Interesfincteriano (LIFT). Métodos: Cinquenta e quatro pacientes (33 homens; 21 mulheres, com mediana de idade de 42 [variação 32-47] anos) foram tratados com LIFT e procedimentos com tampão de fístula de setembro de 2011 até agosto de 2016 por um único cirurgião e foram avaliados retrospectivamente. Todos foram acompanhados por uma mediana de 23,9 (variação de 4 a 54) meses com exame clínico. Vinte e um pacientes foram submetidos a tampão de fístula e 33 pacientes foram submetidos ao procedimento LIFT (4 pacientes do grupo LIFT foram submetidos a LIFT e retalho de avanço da mucosa retal). A taxa de cicatrização e as complicações foram avaliadas clinicamente e por meio de ligações telefônicas. Resultados: O tempo cirúrgico médio para o Tampão foi de 25 ± 17 minutos e para o LIFT foi de 40 ± 20 minutos (p = 0,017) e o tempo médio de internação foi de 2,4 ± 1,1 e 1,9 ± 0,3 (p = 0,01), respectivamente. As primeiras complicações dos procedimentos de tampão e LIFT incluíram: dor anal (33,3%, 66,6%, p = 0,13), secreção perianal (77,8%, 91%, p = 0,62), prurido anal (38,9%, 50,0%, p = 0,71) e sangramento pelo reto (16,7%, 33,3 %, p = 0,39) respectivamente. A média geral de acompanhamento foi de 20,9 ± 16,8 meses, p = 0,68. Não houve diferença estatisticamente significativa entre os dois grupos (21,9 ± 7,5 meses, 19,9 ± 16,1 meses, p = 0,682). A taxa de cicatrização foi de 76,2% (16/21 pacientes) no grupo com tampão de fístula e 81,1% (27/33 pacientes) no grupo LIFT (p = 0,73). Pacientes submetidos ao procedimento LIFT e um retalho de avanço da mucosa tiveram 100% de taxa de cura (4 de 4 pacientes). Nenhuma incontinência fecal e nenhuma expulsão do tampão da fístula foram observadas em nossos pacientes. O tempo de cicatrização variou de 1 a 6 meses após a cirurgia. Não houve abscesso perianal, celulite ou dor no pós-operatório. Conclusões: LIFT e tampão anal são procedimentos seguros para pacientes com fístula anal primária e recorrente. Ambas as técnicas apresentaram excelentes resultados em termos de cicatrização e taxa de complicações. Nenhum de nossos pacientes teve incontinência após 5 anos de acompanhamento. A melhor taxa de sucesso em nossos pacientes foi observada após o procedimento LIFT com retalho de avanço da mucosa. Ensaios clínicos randomizados de maior porte e controlados são necessários para melhor avaliação das opções de tratamento.

ABSTRACT

For the suppression of inflammation in the aneurysm development, we focused on inhibition of an important transcription factor, nuclear factor-kappa B (NF-κB), using a decoy strategy. We newly developed a novel bioabsorbable sheet that delivers NF-κB decoy oligodeoxynucleotide (ODN).We treated 5-week-old SD rats that were induced with abdominal aortic aneurysm (AAA) using 0.5 M CaCl2 with an NF-κB decoy sheet. Four weeks after AAA induction, aortic tissue was excised for further examinations. We showed that this bioabsorbable sheet could deliver the decoy ODN into the target tissues and dissolve within a week. Treatment with the NF-κB decoy sheet reduced the aneurysm size compared with the controls. It also suppressed inflammation due to the effect of NF-κB decoy ODN. Immunohistochemistry revealed that the expression of CD31, CD4, and CD11b in the NF-κB decoy sheet group was significantly lower than in the control sheet group. The NF-κB decoy sheet was absorbed on the target tissue.We have revealed that the bioabsorbable sheet mediated decoy ODN is effective for transfection into target organs. We have also indicated that NF-κB decoy ODN transfection using this sheet has the potential to suppress the dilatation of aneurysm. The bioabsorbable sheet mediated transfection of the decoy ODN can be beneficial for the clinical treatment of AAA and other NF-κB-related cardiovascular diseases.

ABSTRACT

BACKGROUND: Absorbable suspension sutures for tissue repositioning represent a minimally invasive approach to facial rejuvenation. With 2015 FDA 510(k) approval of Silhouette InstaLift™ (Sinclair Pharma, Irvine, CA), a completely absorbable device comprised of 82% PLLA/18% PLGA sutures and bi-directional cones, came the challenge of developing optimal technique for achieving effective, precise, and durable tissue repositioning. Here, the authors discuss the importance of straight-line vector planning (SLVP) and positioning of the suture perpendicular to the plane to be elevated in obtaining optimal results for tissue repositioning. Both the scientific underpinnings of SLVP are presented, along with detailed discussion of technique for suture placement in the mid-face, jawline/jowls, and neck. METHODS: The authors are some of the earliest adopters of absorbable suspension sutures in the United States and have both used InstaLift™ sutures for tissue repositioning and facial recontouring in treatment of more than 500 patients and developed the principles of SLVP as a method to ensure optimal outcomes. RESULTS: Patient case studies illustrating the importance of SLVP are presented. In over 500 patients treated within the authors' practices since InstaLift approval there have been no serious adverse events and noticeable bruising has occurred in less than 5% of patients. Results of repositioning and recontouring are evident for up to 24 months. CONCLUSIONS: Absorbable suspension sutures are a highly adaptable, non-invasive device for lifting and repositioning of descended facial tissue. Outcomes are dependent upon proper technique, including SLVP. J Drugs Dermatol. 2018;17(7):786-793.

ABSTRACT

AIM: To investigate three-year outcomes of patients presenting with nonSTelevation acute coronary syndrome (NSTE-ACS) treated with bioresorbable everolimus-eluting vascular scaffolds (BRS). METHODS AND RESULTS: The study included a total of 488 consecutive patients, enrolled between May 2012 and December 2013 (median age 65 [56-74], 392 men. 269 patients presented with either NSTEMI or unstable angina at the time of enrolling, 219 patients with stable or silent angina. The primary device-oriented endpoint (Target Lesion Failure, TLF) was defined as a combination of cardiovascular death, target vessel myocardial infarction or clinically driven target lesion revascularization.Among the cardiac risk factors, NSTE-ACS patients were more frequently smokers (P = 0.028), had less frequently dyslipidemia (P = 0.003) and a history of prior PCI (P < 0.01).The median follow-up was 1070[763-1197] days. The three-years incidence of TLF was slightly higher but did not differ significantly between groups (NSTE-ACS: 16.3% vs. 15.9%, p = 0.163). Accordingly, there was no difference in any of the other endpoints. CONCLUSION: Treatment of NSTE-ACS with BRS appears to be safe and effective. In this group, risk factors for events during follow up did not differ as compared to the general population.

ABSTRACT

PURPOSE: Various researchers have observed small areas of osteolysis after using bioabsorbable anchors in shoulder surgeries. The purpose of this study is to determine whether radiographic perianchor radiolucent rings after rotator cuff repair are associated with the failure of repair and also assess their clinical implications. Further, the most frequent location of the radiolucent rings in the double-row suture bridge configuration was also assessed. METHODS: One hundred and twenty-nine consecutive patients who underwent arthroscopic rotator cuff repair by suture bridge technique were retrospectively evaluated radiographically and clinically. The number and size of the rings that appeared at each follow-up were recorded. Also, the locations of each ring were recorded as anterior, middle or posterior, and medial or lateral according to the construct of the anchors used for suture bridge technique. The size of the tear, the number of anchors used and age of the patients were compared. Re-tear rates according to ultrasound examinations were also analyzed. RESULTS: After rotator cuff repair, the mean American Shoulder and Elbow Surgeons (ASES) score increased from 46.7 to 88.0 and the overall re-tear rate was 8.5% (11 cases). Seventy-three patients (56.6%) showed RR (total number of 99 rings) at least once during the course of their follow-up and the rings appeared at a mean period of 18.2 months after surgery. Mean size of the rings initially was 5.6 mm and the rings increased or decreased in mean size of 0.4 mm during mean follow-up of 37 months. No correlation was seen with the number of RRs and the rate of re-tears, number of anchors, size of tears, and clinical outcome as determined by the ASES score. Radiolucent ring measurement reproducibility was confirmed by independent, repeated measurements. The rings appeared mostly at anteromedial anchors (75 rings, 75.8%) and the authors suggest that mechanical factors may play a role for the cause of radiolucent rings. CONCLUSIONS: The number and the size of RRs around bioabsorbable anchors after rotator cuff repair do not appear to adversely affect the healing and clinical outcome of ARCR. Most radiolucent rings appeared at anteromedial anchors, indicating that mechanical factors may play a role for the radiolucencies. LEVEL OF EVIDENCE: Case series, level IV.

ABSTRACT

BACKGROUND: Many reconstructive techniques and materials have been reported for repair of skull base defects after sinonasal tumor excision, cerebrospinal fluid (CSF) leaks, and coverage of denuded bone. Synthetic materials have been developed for endoscopic skull base repair to avoid donor-site morbidity. Polydioxanone plate is a bioabsorbable implant designed for nasal septal reconstruction and has the ability to retain strength for at least 10 weeks and absorbs in 6 months. OBJECTIVES: This study aimed to describe the use of polydioxanone plates in endoscopic skull base defect and CSF leak repair, and to describe our experience with the surgical technique and postoperative management. METHODS: This was a retrospective case series of patients who, between May 2013 and December 2015, underwent endoscopic sinus surgery and skull base repair for CSF leak or after excision of a skull base tumor by using polydioxanone plates. Patients who presented with sinonasal inflammatory disease or skull base tumors underwent endoscopic skull base repair by using polydioxanone plates in an underlay fashion and mucosal membrane grafts with or without adjuvant materials in an overlay fashion. The patients were reviewed at 6 days, 6 weeks, and 3 months after surgery. Postoperative adverse events, including CSF leak, infection, bleeding, headache, and graft failure, were recorded. RESULTS: The cases of seven patients (five women, two men; mean age, 53.9 years) were reviewed. Five patients underwent sinonasal tumor resection and two underwent repair for CSF leak. The mean (standard deviation) defect size was 16.4 ± 11.4 mm. There was no evidence of postoperative CSF leak, and lumbar drains were not used. One patient reported transient headache and facial pressure at the 6-week follow-up visit. The surgeons' experience with polydioxanone plate placement, postoperative healing, and follow-up was satisfactory. CONCLUSION: Polydioxanone could be used to achieve rigid repair of endoscopic skull base defects. These early results, although promising, require validation in clinical trials.

ABSTRACT

BACKGROUND: Long-term outcome of drug-eluting stents (DES) for ST-elevation myocardial infarction (STEMI) versus non-ST-elevation acute coronary syndrome (NSTE-ACS) remains unclear. This study sought to compare the long-term outcomes of biodegradable polymer-coated DES in patients with STEMI versus NSTE-ACS. METHODS: We explored a post hoc analysis of the 5-year outcome of the CREATE trial in the subgroup of patients with STEMI (n=318) versus NSTE-ACS (n=1223) who were implanted with biodegradable polymer-coated DES. The primary outcome was the rate of major adverse cardiac events (MACE) at 5 years. Clopidogrel and aspirin for 6 months followed by chronic aspirin therapy were recommended. RESULTS: STEMI patients showed a trend of increase in MACE (8.7% vs. 6.8%, log rank p=0.289) compared to NSTE-ACS patients at 5 years, and a greater risk of cardiac death (5.4% vs. 2.1%, log rank p=0.003), mainly driven by the higher cardiac death rate within the first month after stent placement (log rank p=0.003) and the last year of follow-up (log rank p=0.001). No significant difference in stent thrombosis was found between them (3.1% vs. 2.5%, log rank p=0.653). Prolonged clopidogrel therapy (>6 months) showed no effect on risk of MACE or stent thrombosis between the two groups (both p for interaction >0.1). CONCLUSIONS: STEMI patients have a higher risk of cardiac mortality compared with NSTE-ACS patients after biodegradable polymer-coated DES placement, primarily attribute to more cardiac deaths that happened within the first month after the event and the last year of follow-up.
