Discriminatory of some morphometry and biological aspects of the Cycad blue butterfly, Chilades pandava reared on Cycas and Zamia ornamental palms.

The serious blue butterfly, Chilades pandava -Horsfield, 1829- (Lepidoptera: Lycaenidae) is consider one of the main destructive insect pests for ornamental palms Cycas and Zamia. Biological and morphological measurements were carried out of C. pandava stages reared on Cycas revoluta (Cycadaceae) and Zamia encephalartoides (Zamiaceae). In description details, non-significant variations were recorded between the two gender of cycad blue butterfly in the obtained data, but the male adult was more densely blue or violet than female adult. By the aid of SEM, C. pandava all stages were distinct by long and thick hairs covered all the body. The morphometric characters namely, length, width and venation of wings, body length, forewing, hindwing could be as a guide for taxonomic discrimination. The data showed that the life cycle duration of C. pandava was ranged between 20.64 to 21.7 days. The developmental periods of different C. pandava stages are slightly higher on zamia than cycas palms. This investigation detected that a high survival rate was found on Cycas palms (86%) than the survived rate recording on Zamia palms (82%). In the present study, the described morphometric characters could be used as a guide for taxonomic discrimination of this pest. Consequently, this study added a valuable knowledge about C. pandava to have sound decisions for proposal of its management and conservation in Egypt.

The French Integrative Psychosocial Rehabilitation Assessment for Complex Situations (FIPRACS): Modelization of an Adapted Assessment Method Toward Long-Term Psychiatric Inpatients With Disabling, Severe and Persistent Mental Illness.

For the past forty years, the generalization of community-based approaches has prompted psychiatry into promoting a deinstitutionalization movement and a psychosocial rehabilitation approach (PSR) for individuals with schizophrenia and related difficulties. Unfortunately, this approach generally does not involve the most severe cognitive and psycho-affective clinical situations among this population despite an increasing number of publications advocating that all individuals should be included in PSR and deinstitutionalization programs. In this context, considering the absence of an assessment battery designed for French individuals with particularly disabling, severe, and persistent mental illness (IDSPMI), we constructed an integrative assessment model adapted to this specific population. To select the most suitable tools for this population, a literature review (inspired by the PRISMA protocol) and a systematic review were combined with a clinical assessment study. The literature review first identified the cognitive and psycho-affective functions which mainly influence the day-to-day life adaptation of individuals engaged in a PSR/deinstitutionalization program. The systematic review then gathered all of the useable French validated tools to assess the initially selected dimensions (n = 87). To finish, for each dimension, the selected 87 tools were included in a clinical assessment study performed within a French psychiatric hospital. The authors collected and verified the characteristics of each tool (validity, French norms, French version, the average speed of the test, ease of use, ability to assess other dimensions). Their suitability was also assessed when applied to IDSPMI. Based on this final clinical evaluation, the authors selected one tool per function to create the French Integrative Psychosocial Rehabilitation Assessment for Complex Situations (FIPRACS). This battery is an assessment tailored to the neurocognitive and psycho-affective potentials of IDSPMI. While further validation studies of this battery are ultimately required, the practical/clinical implications of this battery are presented and discussed.

Postgraduate training in surgery: From theory to practice.

INTRODUCTION: Postgraduate training is a time-honored entity, the goal of which was to develop and ensure the acquisition of new medical knowledge for the medical profession. MATERIAL AND METHODS: The main goal of this retrospective study is to analyze the current situation of postgraduate training in surgical disciplines within the framework of the French Universities. We studied the legal texts found in the LéxisNéxis® and Légifrance® sites up until December 1, 2018; references were sought from the Web of Science repository. RESULTS: Postgraduate training in France is mandatory from the legal point of view. Currently there are two possibilities for validation of postgraduate training: either through a recognized continuing professional development (CPD) organization controlled by the National Agency of Continuing Professional Development (NACPD), or by asking for certification through an official accreditation council (AC) (one exists for each surgical specialty), controlled by the High Health Authority that can automatically provide the equivalence of passing through the NACPD organization. DISCUSSION: The continuing education process remains complex. It could well be modified in the near future by the creation of a new certification procedure. With regard to surgical education, whether it concerns the CPD or the accreditation process, the goal is to decrease patient risk and to be an integral part of the overall policy to decrease health care costs. The role of professional national counsels will be more and more important; this is an advantage for each of the surgical specialties. Nonetheless, from the regulatory viewpoint, the decree concerning the role of National Professional Councils has not yet been published in the Journal Officiel de la République Française (French Republic official journal) at the time of writing. CONCLUSIONS: Currently two systems are available for surgeons to comply with the 2016 legislative obligation of continuing education: CPD which is run by the NACPD, and the accreditation process, run by an AC and controlled by the HAS; in the first instance, surgeons can ask for reimbursement from the NACPD and in the second, request that the National Health Insurance Fund for Salaried Employees cover a portion of the litigation insurance premium. LEVEL OF EVIDENCE: Retrospective study: level of evidence IV.

Harmonising measures of knee and hip osteoarthritis in population-based cohort studies: an international study.

OBJECTIVE: Population-based osteoarthritis (OA) cohorts provide vital data on risk factors and outcomes of OA, however the methods to define OA vary between cohorts. We aimed to provide recommendations for combining knee and hip OA data in extant and future population cohort studies, in order to facilitate informative individual participant level analyses. METHOD: International OA experts met to make recommendations on: 1) defining OA by X-ray and/or pain; 2) compare The National Health and Nutrition Examination Survey (NHANES)-type OA pain questions; 3) the comparability of the Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) scale to NHANES-type OA pain questions; 4) the best radiographic scoring method; 5) the usefulness of other OA outcome measures. Key issues were explored using new analyses in two population-based OA cohorts (Multicenter Osteoarthritis Study; MOST and Osteoarthritis Initiative OAI). RESULTS: OA should be defined by both symptoms and radiographs, with symptoms alone as a secondary definition. Kellgren and Lawrence (K/L) grade ≥2 should be used to define radiographic OA (ROA). The variable wording of pain questions can result in varying prevalence between 41.0% and 75.4%, however questions where the time anchor is similar have high sensitivity and specificity (91.2% and 89.9% respectively). A threshold of 3 on a 0-20 scale (95% CI 2.1, 3.9) in the WOMAC pain subscale demonstrated equivalence with the preferred NHANES-type question. CONCLUSION: This research provides recommendations, based on expert agreement, for harmonising and combining OA data in existing and future population-based cohorts.

Physical activity and osteoarthritis: a consensus study to harmonise self-reporting methods of physical activity across international cohorts.

Physical activity (PA) is increasingly recognised as an important factor within studies of osteoarthritis (OA). However, subjective methods used to assess PA are highly variable and have not been developed for use within studies of OA, which creates difficulties when comparing and interpreting PA data in OA research. The aim of this study was, therefore, to gain expert agreement on the appropriate methods to harmonise PA data among existing population cohorts to enable the investigation of the association of PA and OA. The definition of PA in an OA context and methods of harmonization were established via an international expert consensus meeting and modified Delphi exercise using a geographically diverse committee selected on the basis of individual expertise in physical activity, exercise medicine, and OA. Agreement was met for all aims of study: (1) The use of Metabolic Equivalent of Task (MET) minutes per week (MET-min/week) as a method for harmonising PA variables among cohorts; (2) The determination of methods for treating missing components of MET-min/week calculation; a value will be produced from comparable activities within a representative cohort; (3) Exclusion of the domain of occupation from total MET-min/week; (4) The need for a specific measure of joint loading of an activity in addition to intensity and time, in studies of diseases, such as OA. This study has developed a systematic method to classify and harmonise PA in existing OA cohorts. It also provides minimum requirements for future studies intending to include subjective PA measures.

Tennis injury data from The Championships, Wimbledon, from 2003 to 2012.

OBJECTIVE: The primary aims of this retrospective study were to describe the burden of injury presenting to the medical team and the changes in injury profile over 10 years (2003-2012) at The Championships, Wimbledon. Secondary aims included description of gender difference in rates, distribution and pathology of injuries. DESIGN: Retrospective observational cohort of player injury presentations over 10 years (2003-2012) at The Championships, Wimbledon. RESULTS: The overall rate of presentation of injury for all players over the 10-year period was 20.7 per 1000 sets played. Injury rates were lower for male players (17.7 injuries per 1000 sets played) than female players (23.4 injuries per 1000 sets played). There was variability in the numbers of injuries reported by men and women players over the 10-year period. CONCLUSIONS: The rates of presentation of injury at this Grand Slam tennis tournament varied between male and female players, and between years. More robust systems of data collection are required in professional tennis to enable more sophisticated injury data analysis between sexes, years and different playing surfaces.

Assessing risk factors for early hip osteoarthritis in activity-related hip pain: a Delphi study.

OBJECTIVE: Hip pain and injury as a result of activity can lead to the development of early hip osteoarthritis (OA) in susceptible individuals. Our understanding of the factors that increase susceptibility continues to evolve. The ability to clearly identify individuals (and cohorts) with activity-related hip pain who are at risk of early hip OA is currently lacking. The purpose of this study was to gain expert consensus on which key clinical measures might help predict the risk of early hip OA in individuals presenting with activity-related hip pain. The agreed measures would constitute a standardised approach to initial clinical assessment to help identify these individuals. METHODS: This Dephi study used online surveys to gain concordance of expert opinion in a structured process of 'rounds'. In this study, we asked 'What outcome measures are useful in predicting hip OA in activity-related hip pain?' The Delphi panel consisted of experts from sport and exercise medicine, orthopaedics, rheumatology, physiotherapy and OA research. RESULTS: The study identified key clinical measures in the history, examination and investigations (plain anteroposterior radiograph and femoroacetabular impingement views) that the panel agreed would be useful in predicting future risk of hip OA when assessing activity-related hip pain. The panel also agreed that certain investigations and tests (eg, MR angiography) did not currently have a role in routine assessment. There was a lack of consensus regarding the role of MRI, patient-reported outcome measures (PROMs) and certain biomechanical and functional assessments. CONCLUSIONS: We provide a standardised approach to the clinical assessment of patients with activity-related hip pain. Assessment measures rejected by the Delphi panel were newer, more expensive investigations that currently lack evidence. Assessment measures that did not reach consensus include MRI and PROMs. Their role remains ambiguous and would benefit from further research.

Medical treatment of prosthetic vascular graft infections: Review of the literature and proposals of a Working Group.

More than 400000 vascular grafts are inserted annually in the USA. Graft insertion is complicated by infection in 0.5-4% of cases. Vascular graft infections (VGIs) are becoming one of the most frequent prosthesis-related infections and are associated with considerable mortality, ranging from 10 to 25% within 30 days following the diagnosis. Treatment of VGI is based on urgent surgical removal of the infected graft followed by prolonged antibiotherapy. Data regarding the best antibiotherapy to use are lacking since no well designed trial to study antimicrobial treatment of VGI exists. Moreover, since VGIs demonstrate very specific pathophysiology, guidelines on other material-related infections or infective endocarditis treatment cannot be entirely applied to VGI. A French multidisciplinary group gathering infectious diseases specialists, anaesthesiologists, intensivists, microbiologists, radiologists and vascular surgeons was created to review the literature dealing with VGI and to make some proposals regarding empirical and documented antibiotic therapy for these infections. This article reveals these proposals.

[Evaluation of temporality semantic knowledge in normal aging and in mild and moderate stages of Alzheimer's disease]. / Évaluation des connaissances sémantiques de la temporalité au cours du vieillissement normal et de la maladie d'Alzheimer aux stades légers à modérés, étude préliminaire.

OBJECTIVE: Episodic and semantic processes are involved in temporality used in daily life. Episodic memory permits one to place an event on the time axis, while semantic memory makes us aware of the time segmentation and its symbolic representation. Memory of the knowledge connected to the passing of time is materialized on the calendar and can be seen symbolically on the dial of a clock. In AD, semantic memory processes are preserved longer than processes related to episodic memory. We wonder whether the specific field of knowledge about time is altered during AD. METHODOLOGY: We validated a specific evaluation with a control group (354 healthy subjects). Then we applied this battery to assess AD patients to appreciate the feasibility of this tool for this population. We then compared 22 AD patients with a control group matched for age, sex and educational level. Our clinical scale of temporal semantic knowledge consists of four parts: (a) hour reading with a.m. and p.m. hours; (b) using a clock: 12 clock faces with the hour numbers already placed: the patient draws hour and minute hands for various hours; (c) temporal segmentation: exploration of the knowledge on daytime scale and of the calendar; (d) time duration estimation: calculate how long the interview has lasted after indicating the time of its beginning and its end, then the time between 10.40 to 12.00. RESULTS: While age and educational level had an influence on all the scores, in the two groups control and patients, gender did not. Temporal segmentation, independent of the cultural level, revealed the best acquired knowledge in our control population. All the scores differentiated patients from control subjects. The temporal semantic knowledge correlated with the AD severity seemed to be correlated with the attention, verbal comprehension, and some components of executive functions, but was not related to the clock drawing test result. Depression did not have any influence on this scale in our AD group. DISCUSSION: The temporal semantic knowledge clinical scale shows differential alterations, notably in hour reading and using a clock, and less in temporal segmentation. CONCLUSION: Temporal semantic knowledge is altered in AD. The diagnosis and follow-up of these alterations allow professionals and caregivers to consider adaptations of the patient's environment according to their needs.

Early and late results of contemporary management of 37 secondary aortoenteric fistulae.

PURPOSE: Evaluate the results of the two modalities used for the treatment of Secondary Aorto-Enteric Fistula (SAEF): In situ Reconstruction (ISR) and Extra-Anatomic Reconstruction (EAR). The primary endpoints of this study were early standard 30-day mortality and reinfection (RI). Secondary endpoints were perioperative morbidity, late mortality, primary graft patency, and major amputation rates. MATERIAL & METHOD: Diagnosis of SAEF was based on clinical examination and the results of pre-operative duplex or CT scans. Surgical management was performed according to local protocols at the participating institutions: - Elective surgery: ISR or staged EAR. - Emergency surgery: aortic clamping followed by ISR or EAR. - Selected high-risk patients: endovascular repair. Statistical analyses were performed using the actuarial method. Univariate analysis was used for analysis of categorical variables, and multivariate analysis was performed with a Cox proportional hazard regression. RESULTS: A total of 37 patients were included in this retrospective multicentre study. Mean follow-up was 41 months. The majority of the patients (20, 54%) presented acutely. EAR was performed in 9 patients (24%), ISR in 25 (68%), and 3 patients underwent endovascular repair. Bacteriological cultures were negative in 3 patients (9%). The most frequent organisms identified were Candida species and Escherichia coli. The 30-day mortality was 43% (16 patients). Patient age (>75 years) was the sole predictive factor associated with operative mortality (p = 0.02); pre-operative shock was not statistically significant (p = 0.08). There were 2 graft thromboses and 1 femoral amputation. Primary graft patency was respectively 89% at 1 year and 86% at 5 years; limb salvage rates were 100% at 1 and 5 years and 86% at 6 years, with no difference between ISR and EAR. RI occurred after 9.3 ± 13 months in 8 of 17 surviving patients and was fatal in all cases. For all surviving patients, the RI rate at 1 and 2 years was 24% and 41% respectively. There was no significant difference in the rate of RI after ISR or EAR. CONCLUSION: EAR does not appear to be superior to ISR. The risk of RI increased with the length of follow-up, irrespective of the treatment modality. Life-long surveillance is mandatory. Our results with endovascular sealing of SAEF should be considered a bridge to open repair.

[Initial management in oncology: results of CPRIM surveys on 2,583 patient's perceptions and expectations (outside Anticancer Centers)]. / Prise en charge initiale: résultats des enquêtes CPRIM sur le ressenti et les attentes de 2,583 patients (hors centres de lutte contre le cancer).

During the initial phase of management, the caregivers' role is particularly difficult. These two consecutive surveys have been conducted to cover three main aspects: 1) How the initial management took place; 2) What the perceived deficits were; 3) What improvements could be made. A self administered and anonymous questionnaire was given to the patients by physicians. Surveys were conducted in numerous institutions representative of all kinds of practice except for Anticancer Centres. Two thousand five hundred and eighty three adult patients have completed the questionnaire (1366 and 1217 respectively in the first and subsequent survey): women (55%), age under 70 years (76%), breast cancer (32%). Results were rather encouraging. About sixty per cent of the patients are entirely satisfied by the given information and 95% are confident with the department of care. The mean level of global aid is 8.2/10 in the first survey and 8.6/10 in the second one. However, improvements remain needed, particularly for the 8% dissatisfied patients. In spite of the classical bias for these studies, this work gives several concrete responses for improving initial management, particularly for the first consultation in the centre, which has a major impact on the patient satisfaction.

Consensus statement on epidemiological studies of medical conditions in tennis, April 2009.

BACKGROUND: The reported incidence, severity and nature of injuries sustained in tennis vary considerably between studies. While some of these variations can be explained by differences in sample populations and conditions, the main reasons are related to differences in definitions and methodologies employed in the studies. OBJECTIVE: This statement aims to review existing consensus statements for injury surveillance in other sports in order to establish definitions, methods and reporting procedures that are applicable to the specific requirements of tennis. DESIGN: The International Tennis Federation facilitated a meeting of 11 experts from seven countries representing a range of tennis stakeholders. Using a mixed methods consensus approach, key issues related to definitions, methodology and implementation were discussed and voted on by the group during a structured 1-day meeting. Following this meeting, two members of the group collaborated to produce a draft statement, based on the group discussions and voting outcomes. Three revisions were prepared and circulated for comment before the final consensus statement was produced. RESULTS: A definition of medical conditions (injuries and illnesses) that should be recorded in tennis epidemiological studies and criteria for recording the severity and nature of these conditions are proposed. Suggestions are made for recording players' baseline information together with recommendations on how medical conditions sustained during match play and training should be reported. CONCLUSIONS: The definitions and methodology proposed for recording injuries and illnesses sustained during tennis activities will lead to more consistent and comparable data being collected. The surveillance procedures presented here may also be applicable to other racket sports.

A comparison of the mid-term results following the use of bifurcated and aorto-uni-iliac devices in the treatment of abdominal aortic aneurysms.

PURPOSE: To compare the mid-term results following the use of bifurcated (ABIS) and aorto-uniiliac (AUIS) endovascular devices in the treatment of abdominal aortic aneurysms (AAA) in a population of patients deemed to be at high risk for open surgery. MATERIAL AND METHODS: Over a 4 year period (January 2003 to December 2007), 447 underwent elective endovascular aneurysm repair (EVAR) using ZENITH) stent-grafts. Group I comprised patients treated using the AUIS (n=124), and group II those receiving ABIS (n=323). Outcome measures included the assisted technical success rate, perioperative mortality, major complications, freedom from reintervention, and primary and secondary patencies. Factors associated with mid-term clinical failures were determined using univariate and multivariate analyses. RESULTS: The assisted primary technical success rate was 94% and 99% in groups I and II respectively (p=.002). Major perioperative complications occurred in 13 group I patients (10%) vs. 12 group II patients (4%) (p=.005). The 30-day mortality rate was 3.2% vs.1.5% (p=0.2). TASC C and D iliac lesions significantly increased the risk of major perioperative complications (35% vs. 3%; OR=14.94; 95% CI: 5.75 to 38.78; p<.0001). During the follow-up period (median 24 months), secondary procedures were required in 11% and 5% of group I and group II patients respectively (p=.01). Freedom from reintervention at 12, 24 and 36 months was 98%, 90%, and 85% in group I vs. 96%, 92%, and 92% in group II (P<0.005). The primary and secondary patency rates at 3 years were 92% vs. 98% (p=.003) and 97% vs. 99% (p=.04) for groups I and II respectively. In group I, the Crossover Femoro-Femoral Bypass (CFFB) was responsible for 3 major complications (2.4%) which occurred at 7, 12 and 57 months of follow-up. However, the use of AUIS with CFFB did not independently increase the risk of major complications during follow-up (HR=0.108; 95% CI: 0.007 to 1.637; p=.11, Cox proportion model). In both univariate and multivariate analysis, concomitant iliac arterial occlusive disease (IAOD) was the only significant predictor of clinical failure in study population as a whole (OR=3.996; 95% CI: 1.996 to 7.921; p<.0001). CONCLUSION: This study demonstrates that ABIS is associated with better results than AUIS in the management of patients with AAA. Iliac artery occlusive disease was more frequently diagnosed in the AUIS group and this was significantly associated with a higher risk of complications, while the crossover graft itself was not. Nevertheless, the outcomes for both groups are encouraging in this high risk population.

Metatarsal fractures and sports.

OBJECTIVES: Metatarsal fractures are commonly sustained during sport but little is written about metatarsal fractures in the athletic population. Demographics and definitive treatment in patients who sustained metatarsal fractures through sport were compared with an overall metatarsal fracture population. MATERIALS AND METHODS: We used a prospective cohort study from a teaching hospital fracture clinic. Eighteen months of data were coded from presentation with a metatarsal fracture. Demographics, metatarsal fracture, participating sport and treatment were recorded and analysed. RESULTS: 791 patients presented with metatarsal fractures in an 18 month period with 74 metatarsal fractures sustained through sport. In the overall cohort group, there were 443 females and 348 males with a mean age of 44 (age range 15-91) and in the athletic population there were 6 females and 68 males with a mean age of 26 (age range 15-62). The majority of the metatarsal fractures sustained from sport were from soccer (73%), with the fifth metatarsal being the most commonly fractured. The definitive treatment in both groups appears to be similar, where the mainstay of treatment is conservative with the use of cast or early mobilisation with an elasticated support stocking. CONCLUSION: In this cohort approximately 9% of metatarsal fractures were sustained through sport, with soccer being the most common sport. Following high profile injuries to metatarsals in soccer players, it has been suggested that the incidence of these fractures is rising. Thus, it is recommended that a detailed prospective study be undertaken to specifically study the incidence, aetiology and morbidity of metatarsal fractures in the athletic population.

Selecting outcome measures in sports medicine: a guide for practitioners using the example of anterior cruciate ligament rehabilitation.

Using examples from the field of anterior cruciate ligament rehabilitation, this review provides sports and health practitioners with a comprehensive, user-friendly, guide to selecting outcome measures for use with active populations. A series of questions are presented for consideration when selecting a measure: is the measure appropriate for the intended use? (appropriateness); is the measure acceptable to patients? (acceptability); is it feasible to use the measure? (feasibility); does the measure provide meaningful results? (interpretability); does the measure provide reproducible values? (reliability); does the measure assess what it is supposed to assess? (validity); can the measure detect change? (responsiveness); do substantial proportions of patients achieve the worst or best scores? (floor and ceiling effects); is the measure structured and scored correctly? (dimensionality and internal consistency); has the measure been tested with the types of patients with whom it will be used? (sample characteristics). Evaluation of the measure using these questions will assist practitioners in making their judgements.

Physical activity interventions in the workplace: the rationale and future direction for workplace wellness.

The developing and developed worlds are both facing an obesity epidemic with their workers getting bigger, or to be more specific, fatter. As demonstrated elsewhere in this issue, the individual and societal health and economic costs of obesity and physical inactivity are enormous. There is thus a need for regional, national and global action to combat the issues, with programmes broadly divisible into children and adolescents, the workforce, active aging, healthy aging and a broad cross-cutting agenda that focuses on the built environment.

In-situ revascularisation for patients with aortic graft infection: a single centre experience with silver coated polyester grafts.

OBJECTIVE: The aim of this study was to evaluate the early and mid term outcome of patients with aortic graft infection who underwent in-situ revascularisation with a silver coated prosthesis. MATERIAL: From January 2000 to December 2006, 24 consecutive patients (22 male, 2 female) with mean age 67 years were prospectively entered in this study of aortic graft infection at our single centre. Infection was managed with either total (n=19) or partial (n=5) excision of the infected graft and in- situ reconstruction with a silver coated prosthesis, Inter Gard Silver (IGSG). METHODS: The primary endpoint was recurrence of infection. Secondary endpoints were early and late mortality, peri-operative morbidity, primary graft patency, major amputation rates and patient survival. RESULTS: Fourteen patients had a primary graft infection, however 10 of 24 patients had graft infection secondary to aorto digestive (n=9) or aorto urinary (n=1) tract fistulas. Bacteriological cultures were negative in 8 (33%) patients. Most organisms cultivated where virulent and the majority of graft infections were polymicrobial (71%). Silver grafts were placed emergently in 6 (25%) patients. Mean follow up 32.5+/-31.0 months (range 2-78 months). Peri-operative morbidity and mortality were 46% and 21% respectively. Early interventions occurred in 6 (25%) patients and late secondary intervention were required in 3 (15.7%), caused by silver graft reinfection. The late mortality was 26%. CONCLUSION: In-situ reconstruction with the silver graft confirms similarity with other modalities. The greatest advantage for the silver graft is its ease of use but the risk of reinfection remains significant.

Percutaneous closure devices for endovascular repair of infrarenal abdominal aortic aneurysms: a prospective, non-randomized comparative study.

PURPOSE: This study was designed to describe and evaluate our preliminary results with a percutaneous arterial closure device as compared to those obtained with conventional femoral surgical cut down during endovascular repair of abdominal aortic aneurysms (AAA). MATERIAL AND METHODS: Between January 2004 and December 2006, 40 of 86 AAA patients selected for endovascular repair met the criteria for inclusion in this study. Nineteen of these patients (Group A) received a bifurcated endograft placed by direct puncture of the femoral arteries (38 femoral triangles) with closure by a Prostar((R)) percutaneous arterial closure device (Abbott). The other 21 patients (control group B) were managed with a bifurcated endograft placed by conventional open surgery (42 femoral triangles). Data concerning all 40 patients were collected prospectively and analyzed. RESULTS: The technical success rate was 92% (group A) vs 90% (group B), P=0.79. The incidence of perioperative complications was 16% (3/19) in group A and 14% (3/21) in group B (P=0.89). The mean hospital stay was 5.8 days in group A and 7.8 days in group B (P=0.05). The difference in the length of hospitalisation was associated with reduced cost for the percutaneous group (5579.60 euros vs. 7503.60 euros; P=0.04), that counterbalanced the cost induced by the Prostar XL((R)) suture mediated device. Mean follow-up in both groups was 12 months. The overall incidence of locoregional complications after one year of follow-up was 11% (2/19) in group A and 19% (4/21) in group B (P=0.45). CONCLUSION: This study confirms the feasibility and safety of total percutaneous endovascular AAA repair. Our preliminary results suggest that the costs paid by healthcare providers for endovascular AAA repair might not be increased with the selective use of percutaneous closure devices.
