Az Érsebészeti Regiszter működtetése során szerzett tapasztalatok

Randomized controlled trials provide the best evidence in clinical trials; however, they do have limitations. In order to evaluate the effectiveness of treatments, population based registries may also yield useful information about the actual practice and they may enable users to carry out a dynamic follow-up. To evaluate the outcome of vascular procedures, the Vascular Registry in Hungary has been established in 2002. This article presents the establishment and functioning of the Vascular Registry and provides information about scientific results obtained during the past years. The Vascular Registry is an internet based database with on-line input. The backup server is provided by the National Institute for Quality and Organizational Development in Healthcare and Medicines. The database collects data in three different fields: interventions for carotid artery, aneurysm (any type) and lower extremity vascular diseases. Twenty five vascular surgical units record interventions in the registry, which corresponds to two thirds of the whole activity. Since joining the Vascunet Group of the European Society for Vascular Surgery, the registry has contributed to several publications based on evaluation of a large common dataset in different fields of vascular surgery. A validation process has been recently performed which confirmed the internal and external validity of the database. The authors conclude that despite unsolved problems related to financing issues, the Vascular Registry has proved to be a useful tool during the past years. In order to take advantage of the registry to its fullest, measures should be taken to achieve a more complete data recording, increase publication activity on the national dataset, improve the flow of information during operation and develop a system of regular feedback.

Magyarországon végzett infrarenalis aortaaneurysma-műtétek eredményei az Érsebészeti Regiszter adatai alapján (2010–2014)

Absztrakt Bevezetés: A Magyar Angiológiai és Érsebészeti Társaság az Érsebészeti Regiszter létrehozása után elhatározta, hogy az egyes beavatkozások eredményeiről rendszeresen beszámol. Célkitűzés: A szerzők 5 év alatt végzett infrarenalis aortaaneurysma-műtétek eredményeinek bemutatását tűzték ki célul. Módszer: A prospektíven rögzített multicentrikus adatokat retrospektíve dolgozták fel. Az Érsebészeti Regiszter 2010. január 1. és 2014. december 31. közötti adatainak statisztikai elemzéséhez Fischer-féle egzakt próbát és esélyhányadost használtak. Eredmények: Az 1435 beavatkozás 16,72%-ára aneurysmaruptura miatt került sor. A műtétek 78,4%-át 5 nagy betegforgalmú intézet végezte. A rupturált aortaaneurysma csoportba tartozó betegek életkora 71,77±9,82 (átlag±SD) év, a perioperatív mortalitás 33,75%, a nem rupturált aortaaneurysma csoport átlagéletkora 69,50±8,46 év, a perioperatív mortalitás 3,51% volt. Endovascularis beavatkozásoknál mindkét csoportban szignifikánsan kisebb volt a halálozás (rupturált: p<0,05, OR = 0,11; nem rupturált: p<0,05, OR = 0,26), illetve az ápolási időszak (rupturált: p<0,05, OR = 4,55; nem rupturált: p<0,001, OR = 4,27) a nyitott műtétekhez képest. Nagy betegforgalmú intézetekben mindkét csoportban szignifikánsan kisebb volt a halálozás (rupturált: p<0,0001, OR = 0,32; nem rupturált: p<0,0001, OR = 0,23) és az ápolási időszak (rupturált: p<0,05, OR = 3,16; nem rupturált: p<0,001, OR = 3,84) a kis betegforgalmú intézetekhez képest. Következtetések: Stentgraft-implantáció és nagy betegforgalmú intézetek esetében szignifikánsan alacsonyabb a perioperatív mortalitás és a posztoperatív ápolási napok száma. Orv.

Editor's Choice: Contemporary treatment of popliteal artery aneurysm in eight countries: A Report from the Vascunet collaboration of registries.

To access publisher's full text version of this article, please click on the hyperlink in Additional Links field or click on the hyperlink at the top of the page marked Files. This article is open access.To study contemporary popliteal artery aneurysm (PA) repair.Vascunet is a collaboration of population-based registries in 10 countries: eight had data on PA repair (Australia, Finland, Hungary, Iceland, New Zealand, Norway, Sweden, and Switzerland).From January 2009 until June 2012, 1,471 PA repairs were registered. There were 9.59 operations per million person years, varying from 3.4 in Hungary to 17.6 in Sweden. Median age was 70 years, ranging from 66 years in Switzerland and Iceland to 74 years in Australia and New Zealand; 95.6% were men and 44% were active smokers. Elective surgery dominated, comprising 72% of all cases, but only 26.2% in Hungary and 39.7% in Finland, (p < .0001). The proportion of endovascular PA repair was 22.2%, varying from 34.7% in Australia, to zero in Switzerland, Finland, and Iceland (p < .0001). Endovascular repair was performed in 12.2% of patients with acute thrombosis and 24.1% of elective cases (p < .0001). A vein graft was used in 87.2% of open repairs, a synthetic or composite graft in 12.7%. Follow-up was until discharge or 30 days. Amputation rate was 2.0% overall: 6.5% after acute thrombosis, 1.0% after endovascular, 1.8% after open repair, and 26.3% after hybrid repair (p < .0001). Mortality was 0.7% overall: 0.1% after elective repair, 1.6% after acute thrombosis, and 11.1% after rupture.Great variability between countries in incidence of operations, indications for surgery, and choice of surgical technique was found, possibly a result of surgical tradition rather than differences in case mix. Comparative studies with longer follow-up data are warranted

Editor's Choice - Carotid Stenosis Treatment : Variation in International Practice Patterns

Objectives: The aim was to determine current practice for the treatment of carotid stenosis among 12 countries participating in the International Consortium of Vascular Registries (ICVR). Methods: Data from the United States Vascular Quality Initiative (VQI) and the Vascunet registry collaboration (including 10 registries in Europe and Australasia) were used. Variation in treatment modality of asymptomatic versus symptomatic patients was analysed between countries and among centres within each country. Results: Among 58,607 procedures, octogenarians represented 18% of all patients, ranging from 8% (Hungary) to 22% (New Zealand and Australia). Women represented 36%, ranging from 29% (Switzerland) to 40% (USA). The proportion of carotid artery stenting (CAS) among asymptomatic patients ranged from 0% (Finland) to 26% (Sweden) and among symptomatic patients from 0% (Denmark) to 19% (USA). Variation among centres within countries for CAS was highest in the United States and Australia (from 0% to 80%). The overall proportion of asymptomatic patients was 48%, but varied from 0% (Denmark) to 73% (Italy). There was also substantial centre level variation within each country in the proportion of asymptomatic patients, most pronounced in Australia (0-72%), Hungary (5-55%), and the United States (0-100%). Countries with fee for service reimbursement had higher rates of treatment in asymptomatic patients than countries with population based reimbursement (OR 5.8, 95% CI 4.4-7.7). Conclusions: Despite evidence about treatment options for carotid artery disease, the proportion of asymptomatic patients, treatment modality, and the proportion of women and octogenarians vary considerably among and within countries. There was a significant association of treating more asymptomatic patients in countries with fee for service reimbursement. The findings reflect the inconsistency of the existing guidelines and a need for cooperation among guideline committees all over the world. (C) 2017 European Society for Vascular Surgery.

Morphological analysis of the connective tissue reaction in linear hypertrophic scars treated with intralesional steroid or silicone-gel sheeting. A light and electron microscopic study

The linear hypertrophic scar has become the most common type of pathologic scarring. Silicone-gel sheeting is the first line therapy while intralesional steroid is the second. A light and electron microscopic analysis was carried out to reveal differences in tissue reaction following the two different treatments.Two groups of 12 patients each were treated for 4 months. For the first group, diluted Triamcinolone acetonide was injected until an inactive state was achieved. The other group of patients was treated with silicone-gel sheeting. The scars were examined every two weeks and their appearance documented. After reaching the expected therapeutic response, inactive scars were removed. The excised scars were evaluated through light microscopic histopathology and electron microscopy.The light and electron microscopic observations revealed marked differences following treatments. The activity of fibroblasts and the numbers of collagen fibers forming bundles decreased and the orientation of the collagen fibers was more variable in the treated scars. The amount of elastic fibers increased after both steroid and silicone-gel sheeting treatment. Vascularization was also slightly changed, with more capillaries and fewer pre-capillary arteries detected in the treated scars. Both treatments resulted in the same decrease in score but steroid treatment was more rapid in onset. We suggest that the two different treatments work through different mechanisms, although the final functional outcome is similar

Outcome following carotid endarterectomy: lessons learned from a large international vascular registry

OBJECTIVES: The aim of the study was to assess if technical and patient-related factors are related to outcome after carotid surgery. DESIGN: Vascunet is a collaboration of national and regional registries with 10 contributing countries. PATIENTS AND METHODS: Data from 48,035 carotid endarterectomies (CEAs) performed in 383 centres, during 2003-2007, were merged into a common database. RESULTS: CEA was performed without patch (34%), with patch (40%) or with eversion (26%) in 74% for symptomatic and in 26% for asymptomatic disease. Overall (in-hospital and 30-day) mortality was 0.45%. Type of CEA or anaesthesia did not affect mortality, nor did contralateral occlusion. Mortality was higher in patients above the age of 75 years, for both genders (p 75 years had a higher stroke rate than younger women (2.0% vs. 1.6%, p = 0.078); this difference was not observed in men. CONCLUSIONS: Although there are limitations with registry data, the large number of cases involved provides useful information on outcomes, supplementing data from the randomised clinical trials (RCTs)
