Abstract
BACKGROUND Stimulated by published reports of potentially inappropriate application of venous procedures, the American Venous Forum and its Ethics Task Force in collaboration with multiple other professional societies including the Society for Vascular Surgery (SVS), American Vein and Lymphatic Society (AVLS), and the Society of Interventional Radiology (SIR) developed the appropriate use criteria (AUC) for chronic lower extremity venous disease to provide clarity to the application of venous procedures, duplex ultrasound imaging, timing, and reimbursements. METHODS The AUC were developed using the RAND/UCLA Appropriateness Method, a validated method of developing appropriateness criteria in health care. By conducting a modified Delphi exercise and incorporating best available evidence and expert opinion, AUC were developed and scored. RESULTS There were 119 scenarios rated on a scale of 1 to 9 by an expert panel, with 1 being never appropriate and 9 being appropriate. The majority of scenarios consisted of symptomatic indications were deemed appropriate for venous intervention. For scenarios with anatomically short segments of reflux and/or no symptoms, the indications were rated less appropriate. For the indication of edema, a wide dispersion of ratings was observed especially for short segments of saphenous reflux or stenting for iliac/ inferior vena cava disease, noting that there are multifactorial causes of edema, some of which could coexist with venous disease and possibly impact effectiveness of treatment. Several scenarios were considered never appropriate, including treatment of saphenous veins with no reflux, iliac vein or inferior vena cava stenting for iliac vein compression as an incidental finding by imaging with minimal or no symptoms or signs, and incentivizing sonographers to find reflux. CONCLUSIONS The AUC statements are intended to serve as a guide to patient care, particularly in areas where high-quality evidence is lacking to aid clinicians in making day-to-day decisions for common venous interventions. This may also prove useful when applied on a population level, such as practice patterns, and not necessarily to dictate decision making for individual cases. As a product of a collaborative effort, it is hoped that this could be utilized by physicians and multiple stakeholders committed toward improving patient care and to identify and stimulate future research priorities.

The 2020 update of the CEAP classification system and reporting standards. J Vasc Surg Venous Lymphat Disord 2020; 8:342-352.

Abstract
The CEAP (Clinical-Etiology-Anatomy-Pathophysiology) classification is an internationally accepted standard for describing patients with chronic venous disorders and it has been used for reporting clinical research findings in scientific journals. Developed in 1993, updated in 1996, and revised in 2004, CEAP is a classification system based on clinical manifestations of chronic venous disorders, on current understanding of the etiology, the involved anatomy, and the underlying venous pathology. As the evidence related to these aspects of venous disorders, and specifically of chronic venous diseases (CVD, C2-C6) continue to develop, the CEAP classification needs periodic analysis and revisions. In May of 2017, the American Venous Forum created a CEAP Task Force and charged it to critically analyze the current classification system and recommend revisions, where needed. Guided by four basic principles (preservation of the reproducibility of CEAP, compatibility with prior versions, evidence-based, and practical for clinical use), the Task Force has adopted the revised Delphi process and made several changes. These changes include adding Corona phlebectatica as the C4c clinical subclass, introducing the modifier "r" for recurrent varicose veins and recurrent venous ulcers, and replacing numeric descriptions of the venous segments by their common abbreviations. This report describes all these revisions and the rationale for making these changes.

New paradigms for physician-industry relations: overview and application for SVS members. J Vasc Surg 2011; 54:26S-30S.

Abstract
Relationships between physicians and their industry partners have ranged from spectacular collaborations that produce extraordinary advances in patient care, such as endovascular aneurysm repair, to humiliating scandals such as extravagant trips and bogus "consulting" agreements resulting in legal actions. It is the latter which have led many to call for the end of all physician-industry relationships, and the former which mandate their preservation. While these two examples are representative of extremes at each end of the spectrum of this issue, in reality the majority of physician-industry relationships are far more complex, and the line between appropriate and inappropriate, and ethical and unethical, is hard to draw. The benefits of our relationships with industry are many: partnering to develop new therapies and technologies, educating and training physicians around new therapies and technologies, support of continuing medical education (CME), fellowship training, and patient education. The pitfall and danger of this relationship is that support from industry, be it a meal, a pen, an educational grant, or flattery, may unduly and inappropriately influence physician decision making around a specific company's product. While it is clear that free trips are not within the realm of proper interaction, what about unrestricted educational grants to institutions, or support of CME activities, professional society meetings, and new device training? As a result of the intense scrutiny of relationships between physicians and industry recently, multiple diverse entities (Association of American Medical Colleges, American Medical Association, Accreditation Council for Continuing Medical Education, professional medical associations, academic medical centers, industry, and government) have generated guidelines and policies with very different perspectives, reflective of their different missions. These policies range from vague and lenient, with only basic limitation of the physician-industry relationship, to extremely rigid and strict, with only minimal interaction and mission support permitted. Given the many changes in oversight and expectations for the relationship between physicians and industry, it is important for vascular surgeons to be aware of the background behind these modifications, the evidence that they are needed, and the positions of the diverse organizations and institutions that have already defined their policies on this issue.

Renal interventions after abdominal aortic aneurysm repair using an aortic endograft with suprarenal fixation. Am J Surg 2006; 192:577-82.

Abstract
BACKGROUND Our aim was to determine whether suprarenal fixation in endografts compromises renal artery (RA) flow and whether subsequent RA intervention is precluded by the stent struts. METHODS Prospectively acquired data from 104 patients with endovascular aneurysm repair (EVAR) of an abdominal aortic aneurysm using the Zenith endograft (Cook, Inc., Bloomington, IN) were analyzed. The Zenith device uses a 26-mm, uncovered, barbed Z stent for suprarenal function. RESULTS No RA stenosis, occlusion, or infarction resulted from the suprarenal stent. In 3 of 104 (2.9%) patients, RA compromise (2 stenoses, 1 occlusion) was caused by impingement of graft material on the lowermost RA. The 2 RA stenoses were stented successfully at 1 and 7 months post-EVAR. Six of 104 (5.8%) patients developed late stenoses unrelated to the endograft: all were stented successfully from 19 to 36 months after EVAR. One patient with severe RA stenosis had balloon angioplasty pre-EVAR and then was stented electively 6 weeks post-EVAR. CONCLUSIONS Our data show that the suprarenal fixation of the Zenith aortic endograft does not cause RA stenosis, occlusion, or infarction, nor does it preclude post-EVAR renal artery intervention.

Abstract
PURPOSE To bring attention to our observation that soft tissue sarcomas may present initially as deep venous thromboses (DVTs). METHOD A query of our health system database (1996 to 2004) for patients diagnosed with soft tissue sarcomas and DVTs was undertaken. Patient medical records were reviewed to select those patients whose DVT occurred before the diagnosis of their tumor. Patient demographics, tumor classification, presentation, and outcome were noted. RESULTS Six of 19 patients were identified (four men, two women; aged 41 to 85 years). All tumors occurred in the lower extremities. All DVTs occurred in the same extremity as the tumor. Pathology specimens indicated four different types of sarcomas. In five cases, sarcoma diagnosis was delayed as treatment of the DVT occurred. In one, a mass was seen on the initial venous duplex screen. Four are deceased, one remains in treatment, and one was lost to follow-up. The average length of follow-up was 10 months. CONCLUSION Soft tissue sarcomas can initially present as, or even be misdiagnosed as, DVT. Given a delay in diagnosis adversely affects prognosis, it is important that physicians be vigilante for associated tumors when evaluating for suspected DVT.

Abstract
BACKGROUND One adverse outcome of endovascular abdominal aortic aneurysm (AAA) repair (EVAR) is a significantly increased incidence of secondary interventions (SIs) required compared with traditional open aortic repair. We present a consecutive series of EVARs using a single endograft to identify the incidence and types of SIs performed. METHODS From February 1, 2000, to January 31, 2005, we repaired 136 AAAs with the Zenith (Cook, Bloomington, Indiana) endograft. All patients met the same strict anatomic inclusion and exclusion criteria. Follow-up lasted from 1.5 to 61 months (median 36). The indications for SI group A were procedural and technical errors, for group B were aortic morphology, and for group C were device failures. RESULTS Twenty-one SIs were required in 17 of 136 patients (12.5%). Three patients required multiple interventions. Nine patients were in group A, four were in group B, and six were in group C. All but 4 patients required SIs for late (>30 days) complications. CONCLUSIONS Although it is a viable alternative to open aortic repair, EVAR is associated with a significantly higher rate of SIs. To maintain the efficacy of EVAR, patients must be followed-up in a vigilant graft surveillance protocol for life.

Abstract
BACKGROUND Venous leg ulcers are a major cause of morbidity, economic loss, and decreased quality of life in affected patients. Recently, biomaterials derived from natural tissue sources have been used to stimulate wound closure. One such biomaterial obtained from porcine small-intestine submucosa (SIS) has shown promise as an effective treatment to manage full-thickness wounds. Our objective was to compare the effectiveness of SIS wound matrix with compression vs compression alone in healing chronic leg ulcers within 12 weeks. METHODS This was a prospective, randomized, controlled multicenter trial. Patients were 120 patients with at least 1 chronic leg ulcer. Patients were randomly assigned to receive either weekly topical treatment of SIS plus compression therapy (n = 62) or compression therapy alone (n = 58). Ulcer size was determined at enrollment and weekly throughout the treatment. Healing was assessed weekly for up to 12 weeks. Recurrence after 6 months was recorded. The primary outcome measure was the proportion of ulcers healed in each group at 12 weeks. RESULTS After 12 weeks of treatment, 55% of the wounds in the SIS group were healed, as compared with 34% in the standard-care group (P = .0196). None of the healed patients treated with SIS wound matrix and seen for the 6-month follow-up experienced ulcer recurrence. CONCLUSIONS The SIS wound matrix, as an adjunct therapy, significantly improves healing of chronic leg ulcers over compression therapy alone.

Abstract
BACKGROUND Current imaging modalities may not be able to detect endoleaks, differentiate between type II and type III, or localize inflow and outflow sources. We describe a new technique that can characterize endoleaks to guide secondary intervention. METHODS One hundred four patients with Zenith (Cook, Inc.) endograft repair of abdominal aortic aneurysms (AAAs) were monitored by serial computed tomographic angiography (CTA). Endoleaks were evaluated with a dynamic CTA using a stationary table position, 24-mm beam collimation, and continuous scanning over 30 to 40 seconds to create a cine. RESULTS Twelve patients (12%) had endoleaks that persisted or appeared more than 30 days post-deployment. Five patients in whom the standard CT surveillance protocol could not differentiate type II versus type III endoleaks underwent dynamic CTA. This technique accurately characterized the endoleaks and localized inflow and outflow branches to guide the subsequent successful secondary interventions. CONCLUSIONS Dynamic CTA is a useful technique to evaluate endoleaks for characterization and precise localization to guide secondary interventional therapy.

Abstract
BACKGROUND Current experience with carotid body tumors suggesting a high prevalence of associated cervical paragangliomas prompted this review. PATIENTS AND METHODS An 8-year retrospective study of patients with carotid body tumors was undertaken, detailing presentation, diagnosis, and treatment. RESULTS Eleven patients harboring 17 carotid body tumors were discovered. All patients had a neck mass. Seven patients (64%) had bilateral carotid body tumors. Six (55%) reported a positive family history-4 were first-generation relatives, 5 had bilateral tumors, and 3 had other head and neck paragangliomas. Angiography documented 4 associated vagal and 2 glomus jugulare paragangliomas in addition to the carotid body tumors. Precise surgical care limited blood loss to an average of 590 cc. The carotid artery was repaired during 5 resections (29%). Cranial nerve injury occurred in 3 cases, all following vagal body or glomus jugulare resection. Every patient is currently alive, stroke free, and functioning without major disability. CONCLUSIONS Patients with carotid body tumors have a propensity for multiple head and neck paragangliomas. Angiography is diagnostic. The need for associated paraganglioma resection dramatically increases the risk of cranial nerve injury.

Abstract
PURPOSE We compared 66 seeded polytetrafluoroethylene and 53 autologous vein grafts to determine whether endothelial seeding could improve the patency of polytetrafluoroethylene femoral popliteal bypass grafts and to determine whether endothelial seeding could be performed consistently in multiple institutions. METHODS Nine surgeons at four hospitals randomized patients to receive either a seeded polytetrafluoroethylene or a vein graft, but if no satisfactory vein (n = 26) existed, an "obligatory" seeded polytetrafluoroethylene graft was used. RESULTS Scanning electron microscopy confirmed satisfactory initial attachment of endothelium on the discarded ends of the grafts. Patency was compared with the use of log rank analysis and revealed better patency in vein grafts at 30 months (vein = 91.6% +/- 4.1%; seeded polytetrafluoroethylene = 37.8% +/- 9.4%; p = 0.006). Failed grafts revealed anastomotic hyperplasia. CONCLUSIONS (1) Vein graft patency was better than seeded polytetrafluoroethylene grafts; (2) seeding did not improve patency in below-the-knee bypasses as suggested by pilot studies; (3) the failure of seeded grafts was associated with anastomotic hyperplasia but not with the failure of initial endothelial attachment; and (4) each institution reported similar results.

Abstract
The radical anions of molecular oxygen reduction, superoxide (O2), hydrogen peroxide (H2O2), and hydroxyl radical (OH), have been implicated in a number of disease processes, including ischemic bowel injury. This report evaluates the effect of superoxide dismutase (SOD), catalase (CAT), dimethyl sulfoxide (DMSO), selenium treatment, and selenium deficiency on bowel integrity and survival in experimental intestinal ischemia in rats. Ischemic bowel injury was produced in 204 male Sprague-Dawley rats (wt 90 to 100 g) by a one-minute occlusion of the superior mesenteric artery (SMA) with a microaneurysm clip. Experiment I treatment animals (n = 20) received 2.5 mg/kg SOD dissolved in Ringer's lactate, and control animals (n = 71) received Ringer's lactate alone. Experiment II treatment animals (n = 16) received 1 cc of 100% DMSO gavage, and control animals (n = 11) received no treatment. Experiment III treatment animals (n = 17) received 25 mg/kg CAT dissolved in phosphate buffered saline, and control animals (n = 11) received nothing. Experiment IV treatment animals (n = 14) received 300 micrograms of sodium selenate by gavage dissolved in deionized water, and control animals (n = 15) receiving nothing. Experiment V treatment animals (n = 20) were raised from 35 to 50 g size on a selenium deficient diet, and control animals were raised (n = 20) on a normal rat chow diet, until they weighed 100 g when ischemia was induced. At seven days, survival, incidence of bowel perforation or necrosis, and length of survival were compared in each experiment between control and treatment groups using chi 2 analysis.(ABSTRACT TRUNCATED AT 250 WORDS)
