RESUMO
Introduction: Endovascular interventions have become the first-line treatment for peripheral arterial diseases. Athero-thrombotic disorders in the infrarenal aorta are also treated with open surgery, especially if it causes critical stenosis or embolization. The use of traditional stents leads to much more complications in such lesions; however, stentgrafts can provide excellent results.Objectives: We retrospectively analyzed our patients undergoing stengraft implantation due to atherothrombotic diseases in the infrarenal aorta and our early experiences.Methods: We included patients undergoing stentgraft implantation at our department due to symptomatic infrarenal aortic atherothrombotic diseases. We established the suitability for endovascular reconstruction with CT-angiogra-phy. Control CT-angiography was performed 6 weeks after the intervention.Results: 6 patients underwent successful stentgraft implantation between 25 February 2021 and 15 September 2021 at our department due to infrarenal aorta atherothrombotic diseases. 2 patients had critical limb ischaemia and 4 had claudication. Early postoperative complications did not occur. During the follow-up, the patients reported significant walking improvement. Control CT-angiography showed good stentgraft position without stenosis in all patients. Only 1 late postoperative complication (right iliac stent occlusion) occurred. Peripheral thrombolysis was performed for 24 hours; the stent opened and there was no need to perform further interventions.Conclusions: Both our early experiences and international studies have showed that this method is suitable for the treatment of atherothrombotic diseases in the infrarenal aorta. The use of stentgrafts in the treatment of peripheral atherosclerotic diseases is hindered by the high costs of the device, so at present it is subject to individual funding in Hungary.

Introduction and aims. In recent decades health care changes have accelerated enormously. Previously, by learning an effective procedure, the doctor could guarantee his patients the highest level of care for many years. Nowadays, due to the dynamics of development, the renewal cycles of the methods have been shortened, without continuous learning and training, it is already inconceivable to provide the up-to-date care required by patients. Patients and methods. Instead of vascular replacements with prosthetic grafts, which played an important role in vascular reconstructions, the primacy of endovascular techniques has become decisive. It can be significant for aortic aneurysms that can be operated with high invasiveness. The learning of catheter techniques by vascular surgeons made it possible to treat more successfully those limb-threatening cases, which are often associated with extensive vascular involvement, through the so-called hybrid operations. In addition to the increasing prevalence of diabetes worldwide, the higher proportion of critical limb ischemia and the highlighted pathogenic role of multi-resistant bacteria in the disease caused the marginaliation of the use of previously preferred prosthetic grafts. The effectiveness of the treatment of graft infections, which thus become less frequent, is improved by the use of homografts and negative pressure therapy. An effective method of preventing stroke is carotid endarterectomy, the morbidity of which is reduced by the introduction of locoregional anaesthesia allowing direct neuromonitoring. Results/conclusions. Although the acquisition and implementation of new methods has posed a continuous challenge for our specialists and doctors over the past 10 years, our achievements have made our department one of the leading vascular surgery centres in the country.

Összefoglaló. Bevezetés: Az endovascularis intervenciókat kezdetben radiológusok alkalmazták, manapság, megfelelo képzést követoen, jó eredménnyel végeznek ilyen beavatkozásokat érsebészek is. Ezt a világszerte uralkodóvá váló szemléletet kívántuk meghonosítani a Szegedi Tudományegyetemen, melynek bevezetése nélkül elorevetítheto az érsebészet muködésének átalakulása az érrekonstrukciós beavatkozások csökkenésével. Célkituzés: Egyetemünkön radiológus- és érsebész-munkacsoport végez perifériás érintervenciókat. Célunk a két intézet alsó végtagi endovascularis tevékenységének összehasonlítása volt. Módszer: Vizsgálatunkba a Szegedi Tudományegyetemen 2012. 01. 01. és 2019. 12. 31. között alsó végtagi endovascularis beavatkozásokon átesett betegeket válogattuk be. A betegeket a rizikófaktoraik, a kezelt anatómiai régiók, a hospitalizációs ido és a szövodmények tekintetében hasonlítottuk össze. Egyéves utánkövetés során vizsgáltuk a 'redo' mutétek , az amputációk és a halálozások gyakoriságát. Eredmények: A beavatkozásokat 653 esetben radiológus, 573 esetben érsebész végezte. Az érmutoben infrainguinalis (63,2%), a radiológián suprainguinalis érintervenciók (68,6%) történtek nagyobb arányban. A percutan végzett beavatkozásokat vizsgálva a hospitalizációs idoben (2,5 ± 4,4 nap vs. 2,4 ± 2,5 nap, p = 0,78), valamint a minimálisan invazív módon végzett beavatkozások utáni szövodmények gyakoriságában (30/653 - 4,6% és 11/257 - 4,3%, p = 0,837) nem volt különbség a két betegcsoport között. 'Redo' mutétek (73/485 - 15,1% és 33/562 - 5,9%, p<0,001) és amputációk (31/485 - 6,4% és 12/562 - 2,1%, p<0,001) gyakrabban fordultak elo az érmutoben kezelt betegek körében, ebben a csoportban azonban a kritikus végtagischaemia elofordulása is gyakoribb volt (45,4% és 38,6%, p = 0,016). A mortalitásban nem volt szignifikáns különbség (5,8% és 3,9%, p = 0,16). Következtetés: A szoliter érelváltozások kezelését mindkét intézet hasonló hatásfokkal végezte. A több anatómiai régiót érinto betegség miatt érmutoben végzett beavatkozások utáni szövodmények elofordulása kissé magasabbnak bizonyult. Orv Hetil. 2021; 162(24): 943-951. INTRODUCTION: Endovascular interventions were initially performed by radiologists. Nowadays properly trained vascular surgeons also effectively perform these interventions. We wished to apply this widespread practice at our university because without this advancement the number of reconstructive surgeries was expected to decrease significantly. OBJECTIVE: Both radiologists and vascular surgeons perform endovascular interventions at our university. We compared the outcomes of lower extremity endovascular interventions between the two institutes. METHOD: We included patients who underwent lower extremity endovascular interventions between 01. 01. 2012 and 31. 12. 2019. We compared the risk factors, treated anatomical regions, hospitalization time and complication rate. During the one-year follow-up, we examined the occurrence of redo surgeries, amputations and mortality. RESULTS: 653 interventions were performed by radiologists and 573 by vascular surgeons. Vascular surgeons carried out more interventions in the infrainguinal region (63.2%), while radiologists in the suprainguinal region (68.6%). The hospitalization time after percutaneous interventions (2.5 ± 4.4 days vs. 2.4 ± 2.5 days, p = 0.78), and the rate of complications after minimally invasive interventions did not show significant difference (30/653 - 4.6% vs. 11/257 - 4.3%, p = 0.837). Redo surgeries (73/485 - 15.1% vs. 33/562 - 5.9%, p<0.001) and amputations (31/485 - 6.4% vs. 12/562 - 2.1%, p<0.001) occurred more frequently in the surgical group. However, the incidence of chronic limb ischaemia was also higher (45.4% vs. 38.6%, p = 0.016). There was no significant difference in the mortality (5.8% vs. 3.9%, p = 0.16). CONCLUSION: Both institutes had similar efficacy in performing peripheral interventions on solitary vascular lesions. Complications occurred more frequently in the surgical group, but the majority of these patients had extended atherosclerotic diseases. Orv Hetil. 2021; 162(24): 943-951.

Introduction: The incidence of peripheral arterial diseases and the rate of chronic limb-threatening ischaemia are increasing year by year. Minimally invasive peripheral interventions have gradually replaced traditional operations. Earlier steno-occlusion of the popliteal artery was an indication for femoropopliteal bypass below the knee. Nowadays, endovascular procedures are also used, but the indication of the stent placement into the popliteal artery is controversial. Aim: We have been using Jaguar stent for the treatment of popliteal artery steno-occlusion since January 2016. The aim of our study was to evaluate the efficacy of this treatment. Method: We included patients who underwent popliteal artery angioplasty with Jaguar stent placement between 1 January 2016 and 31 December 2017 in our department. During the one-year follow-up, we examined the popliteal stent patency, amputation-free survival and risk factors that influence stent patency. Statistical analysis: For the comparison of mean values, two-sided t-tests were used. Categorical data were analyzed by using chi-square test. Results: 33 patients underwent popliteal or femoropopliteal endovascular intervention with Jaguar stent placement into the popliteal artery. Postoperative complications that required surgical treatment occurred in 2 patients. At the end of the follow-up, the primary patency of the popliteal stents was 58.1%, the secondary patency was 74.2% and amputation-free survival was 96.8%. Conclusion: Compared with international data, the primary patency of the Jaguar stents in our study is relatively lower, but amputation-free survival is much better, and in most cases there is less operative strain compared with traditional operations.
