ABSTRACT

OBJECTIVE: Video motion analysis (VMA) uses fluoroscopic sequences to derive information on catheter and guidewire movement and is able to calculate two-dimensional catheter tip path length (PL) on the basis of frame-by-frame pixel coordinates. The objective of this study was to evaluate the effect of anatomic complexity on the efficiency of completion of defined stages of simulated carotid artery stenting as measured by VMA. METHODS: Twenty interventionists each performed a standardized easy, medium, and difficult carotid artery stenting case in random order on an ANGIO Mentor (Simbionix, Airport City, Israel) simulator. Videos of all procedures were analyzed using VMA software, and performance was expressed in terms of two-dimensional guidewire tip trajectory distance (PL). Comparisons of PL were used to identify differences in cannulation performance of the participants between the three cases of varying difficulty. The procedure was subdivided into four procedural phases: arch navigation, common carotid artery (CCA) cannulation, external carotid manipulation, and carotid lesion crossing. Comparisons of PL were used to identify differences in performance between the three cases of varying difficulty for each of the procedural phases. RESULTS: There were significant differences in PL in relation to anatomic complexity, with a stepwise increase in PL from easy to difficult cases: easy, median of 5000 pixels (interquartile range, 4075-5403 pixels); intermediate, 9059 (5974-14,553) pixels; difficult, 17,373 (11,495-26,594) pixels (P < .001). Similarly, during CCA cannulation, there was a stepwise increase in PL from easy to difficult cases: easy, 749 (603-1403) pixels; intermediate, 3274 (1544-8142) pixels; difficult, 8845 (5954-15,768) pixels (P < .001). There were no observed differences across the groups of anatomic difficulty for the phases of arch navigation, external carotid manipulation, and carotid lesion crossing. CONCLUSIONS: Increasing anatomic complexity leads to significant increases in PL of endovascular tools, in particular during CCA cannulation. This increase in tool movement may have a bearing on clinical outcome.

ABSTRACT

OBJECTIVE: Outcomes from carotid artery stenting (CAS) are related to experience and technical expertise of the operator. Simulation of CAS may enhance clinical proficiency. We interrogated the impact of endovascular simulation of CAS procedures in operators who are at various stages of training. METHODS: Twelve trainees (students [n = 4]; junior surgery residents, postgraduate year [PGY] 1-3 [n = 4]; and senior surgery residents or fellows, PGY 4-7 [n = 4]) were apprised of characteristics of an endovascular simulator and CAS procedures. This was followed by four independent sessions that were assessed for objective measures including procedure and fluoroscopy times and contrast agent use. A qualitative analysis grading steps of CAS by two observers using a Likert scale was performed. One-way analysis of variance and paired t-tests were employed for data analysis. RESULTS: For all participants (n = 12), procedure times (mean, 920 ± 279 seconds for the first session vs 454 ± 156 seconds for the fourth session; P < .01; confidence interval [CI], 315-621) and fluoroscopy cumulative times (mean, 421 ± 230 seconds for the first session vs 222 ± 102 seconds for the fourth session; P < .01; CI, 78-285) decreased with progression of cases. Students and PGY 1-3 residents decreased their procedure times significantly in comparison of initial and final sessions (P < .05 and P < .01, respectively). For all groups, fluoroscopy cumulative times were reduced, and this decrement was significant in the PGY 1-3 cohort (mean, 444 ± 8 seconds for the first session vs 265 ± 51 seconds for the fourth session; P < .01; CI, 81-276). Initial CAS procedure times were significantly different between groups (P < .05), but this was observed to resolve by the final case at study completion. Qualitatively, the Likert scores of students and PGY 1-3 residents significantly improved with case repetition, specifically in the following steps: (1) cannulation of common carotid artery and (2) sizing and deployment of embolic protection device. Senior operators (PGY 4-7) demonstrated consistently better performance overall with minimal change in scoring with case repetition. CONCLUSIONS: Practice leads to improvements in endovascular simulator procedure and fluoroscopy times, especially for more novice trainees. Initial operator performance gaps can be approximated with a few sessions to expected proficiency. Incorporation of endovascular simulators in residency training may assist in shortening the learning curve in rarer endovascular procedures.

ABSTRACT

We report our activities training doctors on vascular access procedures at International University (IU) Hospital in Cambodia through a program facilitated by Ubiquitous Blood Purification International, a nonprofit organization that provides medical support to developing countries in the field of dialysis medicine. Six doctors from Japan have been involved in the education of medical personnel at IU, and we have collectively visited Cambodia about 15 times from 2010 to 2016. In these visits, we have performed many operations, including 42 for arteriovenous fistula, 1 arteriovenous graft, and 1 percutaneous transluminal angioplasty. Stable development and management of vascular access is increasingly required in Cambodia due to increased use of dialysis therapy, and training of doctors in this technique is urgently required. However, we have encountered several difficulties that need to be addressed, including (1) the situation of personnel receiving this training, (2) problems with facilities, including medical equipment and drugs, (3) financial limitations, and (4) problems with management of vascular access.

ABSTRACT

Carotid artery stenting (CAS) has become an integral part of the therapeutic armamentarium offered by cardiovascular medicine programs for the prevention of stroke. The purpose of this expert consensus statement is to provide physician training and credentialing guidance to facilitate the safe and effective incorporation of CAS into clinical practice within these programs. Since publication of the 2005 Clinical Competence Statement on Carotid Stenting, there has been substantial device innovation, publication of numerous clinical trials and observational studies, accumulation of extensive real-world clinical experience and widespread participation in robust national quality improvement initiatives [5]. Collectively, these advances have led to substantial evolution in the selection of appropriate patients, as well as in the cognitive, technical and clinical skills required to perform safe and effective CAS. Herein, we summarize published guidelines, describe training pathways, outline elements of competency, offer strategies for tracking outcomes, specify facility, equipment and personnel requirements, and propose criteria for maintenance of CAS competency.

ABSTRACT

PURPOSE: To assess the face and content validity of a novel, full physics, full procedural, virtual reality simulation housed in a hybrid procedure suite. METHODS AND MATERIALS: After completing 60 minutes of hands-on training in uterine artery embolization and coronary angioplasty, 24 radiologists and 18 cardiologists with mean 10 years of endovascular experience assessed the functionality of a comprehensive hybrid procedure suite simulation (Orcamp; Orzone, Gothenburg, Sweden). RESULTS: C-arm and operating table functionality and realism were reliably (α = 0.0.89-0.92) rated highly (80/100). Performance realism of the catheter, guide wire, fluoroscopy image, electrocardiogram, and vital signs readout also reliably and statistically significantly predicted subjects' overall positive assessment (mean = 87/100) of the simulation experience in a multiple regression model (α = .83; r = 0.85 and r(2) = 0.67; P < .0001). CONCLUSIONS: This study reports a quantitative evaluation of a comprehensive simulation of an authentic procedure suite for image-guided intravascular procedures. This new facility affords the opportunity for trainers to provide higher fidelity training of operative technical, procedural, and management skills in the realistic context of a complete procedure suite with all its complexities and potential distractions.

ABSTRACT

OBJECTIVE: Surging interest in the 0 + 5 integrated vascular surgery (VS) residency and successful recruitment of the top students in medical school requires early exposure to the field. We sought to determine the impact of a high-fidelity simulation-based preclinical endovascular skills course on medical student performance and ultimate career specialty choices. METHODS: Fifty-two preclinical medical students enrolled in an 8-week VS elective course from 2007 to 2009. Students completed a baseline and postcourse survey and performed a renal angioplasty/stent procedure on an endovascular simulator (pretest). A curriculum consisting of didactic teaching covering peripheral vascular disease and weekly mentored simulator sessions concluded with a final graded procedure (posttest). Long-term follow-up surveys 1 to 3 years after course completion were administered to determine ultimate career paths of participants as well as motivating factors for career choice. RESULTS: Objective and subjective performance measured on the simulator and through structured global assessment scales improved in all students from pre- to posttest, particularly with regard to technical skill and overall procedural competency (P < .001). Prior to enrolling in the course, 9% of the students expressed high interest in VS, and after completing the course, this response nearly tripled in terms of seriously considering VS as a career option (P = .03). Overall interest postcourse in VS and procedural-based surgical specialties was nearly 90%. In long-term follow-up, 25% were still strongly considering integrated VS residencies, with other top career choices including surgical subspecialties (64%), radiology (10%), and cardiology (6%). Most respondents indicated major reasons for continued interest in VS were the ability to practice endovascular procedures on the simulator (92%) and mentorship from VS faculty (70%). CONCLUSIONS: Basic endovascular skills can be efficiently introduced through a simulation-based curriculum and lead to improved novice performance. Early exposure of preclinical medical students provides an effective teaching and recruitment tool for procedural-based fields, particularly surgical subspecialties. Mentored exposure to endovascular procedures on the simulator positively impacts long-term medical student attitudes toward vascular surgery and ultimate career choices.

ABSTRACT

OBJECTIVES: Complex endovascular skills are difficult to obtain in the clinical environment. Virtual reality (VR) simulator training is a valuable addition to current training curricula, but is there a benefit in the absence of expert trainers? METHODS: Eighteen endovascular novices performed a renal artery angioplasty/stenting (RAS) on the Vascular Interventional Surgical Trainer simulator. They were randomized into three groups: Group A (n = 6, control), no performance feedback; Group B (n = 6, nonexpert feedback), feedback after every procedure from a nonexpert facilitator; and Group C (n = 6, expert feedback), feedback after every procedure from a consultant vascular surgeon. Each trainee completed RAS six times. Simulator-measured performance metrics included procedural and fluoroscopy time, contrast volume, accuracy of balloon placement, and handling errors. Clinical errors were also measured by blinded video assessment. Data were analyzed using SPSS version 15. RESULTS: A clear learning curve was observed across the six trials. There were no significant differences between the three groups for the general performance metrics, but Group C made fewer errors than Groups A (P = .009) or B (P = .004). Video-based error assessment showed that Groups B and C performed better than Group A (P = .002 and P = .000, respectively). CONCLUSION: VR simulator training for novices can significantly improve general performance in the absence of expert trainers. Procedure-specific qualitative metrics are improved with expert feedback, but nonexpert facilitators can also enhance the quality of training and may represent a valuable alternative to expert clinical faculty.

ABSTRACT

OBJECTIVE(S): Patient-specific simulated rehearsal (PsR) is a technological advance within the domain of endovascular virtual reality (VR) simulation. It allows incorporation of patient-specific computed tomography Digital Imaging and Communications in Medicine (CT DICOM) data into the simulation and subsequent rehearsal of real patient cases. This study aimed to evaluate whether a part-task rehearsal (PTr) of a carotid artery stenting procedure (CAS) on a VR simulator is as effective as a full-task (FTr) preoperative run through. METHODS: Medical trainees were trained in the CAS procedure and randomised to a PTr or FTr of a challenging CAS case (Type-II arch). PTr consisted of 30 min of repeated catheterisations of the common carotid artery (CCA). Thereafter, both groups performed the CAS procedure in a fully functional simulated operating suite (SOS) with an interventional team. Technical performances were assessed using simulator-based metrics and expert ratings. Other aspects of performance were assessed using the Non-Technical Skills for Surgeons (NOTSS) scoring. RESULTS: Twenty trainees were evenly randomised to either PTr or FTr. No differences in performance were seen except for the total time the embolic protection device (EPD) was deployed (9.4 min for the PT vs. 8.1 min for the FT, p = 0.02). Total time (26.3 vs. 25.5 min, p = 0.94), fluoroscopy time (15.8 vs. 14.4 min, p = 0.68), number of roadmaps (10.5 vs. 11.0, p = 0.54), amount of contrast (53.5 vs. 58.0 ml, p = 0.33), time to deploy the EPD (0.9 vs. 0.8 min, p = 0.31) and time to catheterise the CCA (9.2 vs. 8.9 min, p = 0.94) were similar. Qualitative performances as measured by expert ratings (score 24 vs. 24, p = 0.49) and NOTSS (p > 0.05 for all categories) were also comparable. CONCLUSIONS: Part- and full-task rehearsals are equally effective with respect to the operative performance of a simulated CAS intervention. This finding makes a patient-specific rehearsal more efficient and may increase the feasibility of implementation of this technology into medical practice.

ABSTRACT

AIM: The literature continues reporting a high complication rate for carotid artery stenting (CAS) during the learning-curve phase (LCP). The aim of this study was to report a simple and reproducible method designed to improve CAS results during the LCP. METHODS: Between February 2007 and December 2009, a qualified vascular surgeon ran a proctorship program for CAS. The program was divided into four practical phases: in the teaching phase (a) the first 20 CAS were performed by the proctor assisted by a trainee surgeon; in the training phase (b) for the 21st to the 50th CAS the trainee surgeon was supervised by the proctor; in the skilled phase (c), between the 51st and the 80th procedure, a trainee surgeon performed CAS while the proctor was scrubbed-in but operating only on demand; in the final phase (d), following the 81st CAS, the procedure was performed without the proctor's presence. The inclusion criterion was carotid stenosis ≥70% and patient selection was performed for the first 40 cases based on patient and lesion characteristics. The procedure for CAS was standardized. RESULTS: Four trainees performed 604 CASs in two centers. The procedural success rate of CAS was 98.8% (N.=594/604) without any differences among the four trainees (P=0.902). The overall TIA, myocardial infarction, minor, major and fatal stroke rate at 30 days was respectively 1.7% (N.=10), 0.8% (N.=5), 1.2% (N.=7), 0.64% (N.=4) and 0.3% (N.=2). The effectiveness of this program was demonstrated by a significant decrease in the proctor's intervention between phase b and phase c (P<0.001) and by a similar trend in the complication rate achieved by the four trainees, in all phases and centers (P=0.075 and 0.788, respectively). CONCLUSION: This preliminary experience of a proctorship program in the LCP, together with patient selection and standardization of the procedure and materials used, seems to be safe and reproducible. Moreover, possibly randomized, studies comparing different CAS training techniques are needed in order to validate our findings.

ABSTRACT

OBJECTIVES: This study evaluated virtual reality (VR) simulation for endovascular training of medical students to determine whether innate perceptual, visuospatial, and psychomotor aptitude (VSA) can predict initial and plateau phase of technical endovascular skills acquisition. METHODS: Twenty medical students received didactic and endovascular training on a commercially available VR simulator. Each student treated a series of 10 identical noncomplex renal artery stenoses endovascularly. The simulator recorded performance data instantly and objectively. An experienced interventionalist rated the performance at the initial and final sessions using generic (out of 40) and procedure-specific (out of 30) rating scales. VSA were tested with fine motor dexterity (FMD, Perdue Pegboard), psychomotor ability (minimally invasive virtual reality surgical trainer [MIST-VR]), image recall (Rey-Osterrieth), and organizational aptitude (map-planning). VSA performance scores were correlated with the assessment parameters of endovascular skills at commencement and completion of training. RESULTS: Medical students exhibited statistically significant learning curves from the initial to the plateau performance for contrast usage (medians, 28 vs 17 mL, P < .001), total procedure time (2120 vs 867 seconds, P < .001), and fluoroscopy time (993 vs. 507 seconds, P < .001). Scores on generic and procedure-specific rating scales improved significantly (10 vs 25, P < .001; 8 vs 17 P < .001). Significant correlations were noted for FMD with initial and plateau sessions for fluoroscopy time (r(s) = -0.564, P = .010; r(s) = -.449, P = .047). FMD correlated with procedure-specific scores at the initial session (r(s) = .607, P = .006). Image recall correlated with generic skills at the end of training (r(s) = .587, P = .006). CONCLUSIONS: Simulator-based training in endovascular skills improved performance in medical students. There were significant correlations between initial endovascular skill and fine motor dexterity as well as with image recall at end of the training period. In addition to current recruitment strategies, VSA may be a useful tool for predictive validity studies.

ABSTRACT

OBJECTIVES: Vascular surgery training has evolved from a single clinical year after general surgery training to a multi-year training program to encompass such entities as noninvasive vascular laboratory, office-based procedures, and endovascular techniques. Simultaneously, members of the vascular surgery community have had to undergo significant training to become facile with endovascular techniques. We surveyed vascular surgery trainees on the online Vascular Surgery In-Training Examination (VSITE) in 2008 and 2009 to assess who trained them in percutaneous techniques. METHODS: Vascular surgery trainees in the Independent (2-year) and Integrated (5-year) training programs were asked to participate in a survey upon completion of the VSITE in 2008 and 2009. Examinees were asked to select whether vascular surgeons, cardiologists, or interventional radiologists trained them in carotid angioplasty and stenting (CAS), thoracic endografts (TEVAR), endovascular abdominal aortic aneurysm repair (EVAR), renal artery intervention, iliac stenting, superficial femoral artery (SFA), and tibial artery percutaneous interventions. RESULTS: Survey response rate was 79.6% (191 of 240). Results of the survey are shown in Table I. In 2009, vascular surgeons provided more than 84% of the training to vascular surgery residents. Only six respondents had >50% of their percutaneous training with interventional radiology and two with cardiologists. CONCLUSION: Vascular surgeons involved in resident education have been able to retrain themselves in endovascular techniques such that they are now able to provide greater than 80% of the endovascular experience to vascular surgery residents.

ABSTRACT

OBJECTIVES: To explore what characterises the development of endovascular expertise and to construct a novel global assessment instrument. DESIGN: Literature review and an experimental study. MATERIALS AND METHODS: The literature was searched for information regarding available global rating scales (GRSs); scientific societies' official statements on endovascular competence; and task analyses of endovascular procedures. In the experimental study, clinicians performed a video-recorded simulated iliac-artery stenting procedure. Subsequently, by using the method of retrospective verbalisation, the clinicians were interviewed while watching their performance on video commenting on key issues of the construct. Data from all sources were analysed, categorised and synthesised into a novel rating scale. RESULTS: Available GRSs primarily included technical aspects of performance, whereas the competence statements, task analyses and clinicians' perceptions added a range of non-technical aspects. The novel rating scale SAVE (Structured Assessment of endoVascular Expertise) differs from prior scales by including issues of pre-planning; prediction of challenges; preparation of tools; management of imaging presentation; distinction of technical skills into external and internal control according to operator focus of visual attention; adaptation of strategy; clinical decision making; use of assistant; complications; inter-personal skills; and post-procedural planning. CONCLUSIONS: The essence of developing endovascular expertise goes far beyond mere technical aspects.

ABSTRACT

BACKGROUND: Previously, the Stenting and Angioplasty with Protection of Patients with High Risk for Endarterectomy (SAPPHIRE) randomized trial showed that carotid artery stenting (CAS) was not inferior to carotid endarterectomy (CEA) in the treatment of high-surgical risk patients. OBJECTIVE: The primary objective of the SAPPHIRE Worldwide Registry is to evaluate 30-day major adverse events (MAE) after CAS performed by physicians with varied experience and utilizing a formal training program. Data will be analyzed on the overall patient population and by high-risk inclusion criteria. METHODS: SAPPHIRE Worldwide is a multicenter, prospective, postapproval registry to evaluate CAS with distal protection in patients at high-risk for surgery using the Cordis PRECISE Nitinol Stent and ANGIOGUARD XP/RX Emboli Capture Guidewire. Participating physicians are encouraged to treat patients according to their standard of practice and consistent with current Food and Drug Administration-approved labeling. RESULTS: Enrollment began in October 2006. Data are available on the first 2,001 patients enrolled and followed to 30 days. Of these patients, the mean age was 72.2 +/- 9.75 yr; 62% were male; and 27.7% were symptomatic. Entry criteria for surgical high-risk included anatomic (n = 716), physiologic (n = 918), or both risk factors (n = 327). At 30-day follow-up, the MAE was 4.4% (death 1.1%, stroke 3.2%, MI 0.7%) for the overall population. Patients with anatomic risk had a significantly lower 30-day MAE than patients with physiologic risk (2.8% vs. 4.9%, P = 0.0306), respectively. CONCLUSIONS: While the number of physicians performing CAS continues to increase, MAE rates seen in this registry (4.4%) are well within an acceptable range, as was first seen in the SAPPHIRE randomized trial (4.8%). A significant decrease in MAE was seen in patients with anatomic risk compared with physiologic risk factors. The SAPPHIRE Worldwide Registry supports the use of CAS as an alternative to CEA in patients who are at high-risk for surgery due to anatomic risk factors.

ABSTRACT

OBJECTIVE: To evaluate the influence of the status of vascular surgery (VS) training paradigms on the actual practice of endovascular therapy among the European countries. METHODS: An email-based survey concerning vascular surgery training models and endovascular practices of different clinical specialties was distributed to a VS educator within 14 European countries. European Vascular and Endovascular Monitor (EVEM) data also were processed to correlate endovascular practice with training models. RESULTS: Fourteen questionnaires were gathered. Vascular training in Europe appears in 3 models: 1. Mono-specialty (independence): 7 countries, 2. Subspecialty: 5 countries, 3. An existing specialty within general surgery: 2 countries. Independent compared to non-independent certification shortens overall training length (5.9 vs 7.9 years, p=0.006), while increasing overall training devoted specifically to VS (3.9 vs 2.7 years, p=0.008). Among countries with independent certification an average of 76% of aortic and 50% of peripheral endovascular procedures are performed by vascular surgeons, while the corresponding values, for countries with a non-independent certification, are 69% and 36% respectively. Countries with independent vascular certification, despite their lower average endovascular index (procedures per 100,000 population), reported a higher growth rate of aortic endovascular procedures (VS independent 132% vs VS non-independent 87%), within a four-year period (2003-2007). Peripheral endovascular procedures, though, have similar growth rates in both country groups (VS independent 62% vs VS non-independent 60%). CONCLUSIONS: In European countries with VS as an independent specialty, vascular surgeons have a shorter total training period but spend more time in VS training, although they may not undertake a greater proportion of the endovascular procedures their countries appear to have adopted endovascular technologies more rapidly compared to the ones with non-independent VS curricula. Whether such differences influence patient outcomes requires investigation in future studies.

ABSTRACT

Radiology registrars were observed performing a left renal artery angioplasty using a proprietary training simulator up to five times during their first year of training. Total procedure time, fluoroscopy times, and metric information from the machine were recorded. Each step of the procedure was judged by an observer and a mistake profile was generated. Fifty-two runs were completed by 12 trainees. The mean procedure time decreased from 16.6 min to 9.8 min over the five runs. The number of mistakes ranged from zero to ten and the mean number of mistakes made varied from 0.7 to 2.6 per procedure without any particular trend. Our study demonstrates that training on the simulator does improve performance. The mistakes made throughout training indicates the potential benefit from further simulator training. It remains unclear how to integrate this form of training in current educational programs.

ABSTRACT

OBJECTIVE: To evaluate the long-term results of an educational program compared to usual care. METHOD: A longitudinal study in which 56 participants from a previous study (randomized controlled clinical trial) were evaluated twelve months after the percutaneous coronary intervention (PCI). Health-related quality of life (HRQoL) was assessed by the Medical Outcomes Study: 36-item Short Form (SF-36), and anxiety and depression symptoms were assessed by the Hospital Anxiety and Depression Scale (HADS). A repeated measures analysis of variance was performed (significance level 0.05). RESULTS: Participants in the educational program showed improvement of HRQoL in the Role-Emotional domain, while those in the usual care did not present changes (p=0.05). Both groups showed improvement in the Role-Physical (p = 0.001) and Bodily Pain (p=0.01) domains over time. There were no differences in the symptoms of anxiety and depression. CONCLUSION: One year after the PCI, there were significant differences between groups only for the Role-Emotional domain of the SF-36.

ABSTRACT

BACKGROUND: As with new laparoscopic techniques, the ability to convince surgeons and gastroenterologists to embrace endolumenal techniques and the additional training required to perform the new procedures will correlate with how rapidly endolumenal therapies are adopted. The authors measured their ability to change attitudes among surgeons, who may or may not perform endoscopy as a part of their practice, toward endolumenal therapies. METHODS: As part of the endoluminal therapy postgraduate course presented at the annual Society of American Gastrointestinal Endoscopic Surgeons (SAGES) meeting in Ft. Lauderdale, Florida 2005, experts presented current literature and data on new endolumenal techniques. The participants, primarily of surgeons, were polled electronically about a number of case scenarios before and after their presentation. Each scenario was relevant to the topic presented and chosen to reflect potentially controversial disease processes with traditional or endolumenal treatment options. The responses were collected in real time and displayed to course participants. RESULTS: A panel of 10 experts presented data on a range of endolumenal therapies including endolumenal treatment for gastroesophageal reflux disease (GERD), endoscopic stenting, endoscopic treatments in bariatric surgery, intraoperative endoscopy, endoscopic mucosal resection (EMR), transanal endoscopic microsurgery (TEM), mucosal ablation for Barrett's esophagus, intralumenal resection, translumenal endoscopic surgery, and how to educate surgeons in new endolumenal techniques. Demographic data showed that 83.6% of the participants performed endoscopy as part of their practice. A comparison with traditional surgical options showed a statistically significant positive attitude change (p < 0.05) toward adoption of most endolumenal techniques after expert presentation. Only EMR and TEM did not show a statistically significant change in the participants' willingness to adopt these techniques. There was no significant change in the attitudes of how best to train surgeons. After presentation of the training options, 76% of the respondents believed that these techniques should be taught in residency. CONCLUSIONS: The education of surgeons in new endolumenal therapeutic techniques can have a significant impact in terms of changing practice attitudes and may accelerate adoption of new endoscopic techniques.

ABSTRACT

In the 25 years that formalized vascular surgery training and certification has been, in effect, the treatment of patients with peripheral vascular disease has undergone dramatic changes, largely due to the emergence of a wide variety of endoluminal techniques and devices that enable minimally invasive treatment of conditions that formerly required operative intervention. Unfortunately, vascular surgeons, for the most part, were painfully slow to embrace these new and evolving technologies, which became increasingly complex as they expanded to treat virtually all vascular maladies in all peripheral vascular territories. Not surprisingly, this left vascular surgeons disadvantaged relative to other disciplines for whom these techniques were more familiar, and we have spent the better part of the last decade playing catch-up to master them and regain our role as the only specialty qualified to offer all types of therapies to our patients with vascular disease. This has caused some to question what changes need to be made in our vascular surgery training paradigm for our new trainees to attain and maintain a preeminent role in the evaluation and treatment of patients with peripheral vascular disease. While the knee-jerk response is to consider special or supplemental training programs for these advanced techniques, or even certificates of added qualifications for the more challenging of them, such as carotid stenting, we believe that all that is really needed is for the vascular surgical community as a whole, and particularly those faculty in training programs, to truly embrace these new technologies and apply them to the patients they are already rendering care to. Given the prevalence of vascular disease and overall wealth of clinical material already present in most training programs, the simple willingness to apply endoluminal therapies to our existing patient populations is all that would really be needed to insure that all future graduates of vascular surgery training programs are fully competent in all of the current endoluminal therapies and well-positioned to continue to evolve with the field. The real question to be considering, which is beyond the focus of this article, is how we are to maintain our open surgical skills in the era of minimally invasive treatment of vascular disease.

ABSTRACT

Fellowship training in vascular surgery over the last several decades has typically involved 1 to 2 years of clinical training incorporating open surgical techniques, some noninvasive vascular diagnostic laboratory, outpatient and inpatient experiences, occasionally basic science research, and more recently training in endovascular procedures. In order to meet the projected increased need for vascular care in the future, vascular surgery training needs to undergo both structural and content modifications if the field is to stay at the forefront in caring for the patient with vascular disease. This article addresses these issues and potential solutions.
