Introduction: Solid evidence is not available on the ideal technique of surgical repair (open or endovascular) of noninfrarenal abdominal aortic aneurysms. Objective: Our aim was to analyze the postoperative effect of mortality and the level of proximal cross-clamping of the patients who underwent open surgical aortic repair of non-infrarenal abdominal aortic aneurysms with intact wall. Method: This is a retrospective, single-centre study, which reviews the results of open surgical repair, performed for intact non-infrarenal abdominal aorta aneurysms between 2005 and 2017. Aneurysms were analyzed in two groups, based on the level of aortic cross-damping: juxta-pararenal aortic aneurysm group with inter- or suprarenal aortic cross-clamping and suprarenal aortic aneurysm group with supraceliac aortic cross-clamping. Primary endpoints were 30-day, 1-, 2- and 5-year mortality. Secondary endpoints were postoperative acute kidney injury, including hemodialysis, and major postoperative complications. Results: In our clinic, 94 patients underwent open surgical aortic repair with cross-clamping above at least one renal artery. The median follow-up was 3.14 (1.55-5.00) years. The overall 30-day, 1-, 2- and 5-year mortality were 9%, 20%, 27% and 48%, respectively. The mortality was significantly lower in the juxta/pararenal abdominal aortic aneurism group at 30 day and 1 year. The overall perioperative incidence of acute kidney injury was 54% and 30% at discharge. Significantly more in-hospital acute renal dysfunction was noticed in the patients with suprarenal aortic aneurysm than with juxta/pararenal aneurysm, however, the difference was not significant at discharge. Major postoperative complications were more frequent in the suprarenal aneurysm group. Conclusion: Open surgical repair of abdominal aortic aneurysms with supraceliac aortic cross-clamping is associated with significantly higher morbidity, early and mid-term mortality than the repair of juxta/pararenal aneurysms. Chronic kidney disease and major postoperative complications are independent factors of mid- and long-term mortality.

Összefoglaló. Bevezetés: Az elmúlt évtizedekben számos országban jelentős mértékben változott a hasi aortaaneurysmák sebészi kezelése az eredményesebb ellátás céljából: endovascularis beavatkozások terjedése, nagy betegforgalmú aortacentrumok kialakítása. Célkitűzés: A Magyarországon, infrarenalis aortaaneurysmák miatt végzett beavatkozások rövid távú eredményeinek elemzése elsősorban műtéti technika (endovascularis vs. nyitott aortareconstructio), intézeti betegforgalom (kis vs. nagy betegforgalmú intézet) és időszak (2010-2014 vs. 2015-2019) alapján. Módszer: A Nemzeti Érsebészeti Regiszterben 2010. 01. 01. és 2019. 12. 31. között prospektíven rögzített multicentrikus adatok retrospektív feldolgozása. Eredmények: A regiszterben 3206 infrarenalis aortaaneurysma-műtétet rögzítettek. A második öt évben jelentősen nőtt az endovascularis aortareconstructio aránya a nyitotthoz képest (p<0,0001), illetve a nagy betegforgalmú intézetek szignifikánsan több rupturált aortaaneurysmát láttak el, mint a kis betegforgalmú intézetek (p<0,0001) az első öt évhez viszonyítva. A perioperatív mortalitás rupturált aortaaneurysma miatt a nagy betegforgalmú intézetekben végzett nyitott aortareconstructio esetén szignifikánsan alacsonyabb volt a kis betegforgalmú intézetekkel szemben az első öt évben (p = 0,0011), illetve a nagy betegforgalmú intézetekben végzett endovascularis aortareconstructio esetén szignifikánsan alacsonyabb volt a nyitottal szemben a második öt évben (p = 0,029). A nem rupturált aortaaneurysma-műtétek perioperatív mortalitása a nagy betegforgalmú intézetekben végzett nyitott aortareconstructio esetén szignifikánsan alacsonyabb volt a kis betegforgalmú intézetekhez képest az első és a második öt évben is (p = 0,0007; p = 0,004). Mind a nagy, mind a kis betegforgalmú intézetekben végzett endovascularis aortareconstructio esetén szignifikánsan alacsonyabb volt a perioperatív mortalitás a második öt évben (p<0,0001; p<0,0001). A rupturált és a nem rupturált aortaaneurysmák perioperatív mortalitásának független rizikófaktora az intézetek betegforgalma (p = 0,006; p = 0,004), a betegek életkora (p<0,0001; p = 0,001), a preoperatív renalis megbetegedés (p = 0,007; p = 0,007), a transzfúzióigény (p<0,0001; p<0,0001), illetve nem rupturált aortaaneurysmák esetében a műtéti technika (p<0,0001) is. Következtetés: Endovascularis aortareconstructio és nagy betegforgalmú intézetek esetében szignifikánsan alacsonyabb perioperatív mortalitás érhető el. Orv Hetil. 2021; 162(31): 1233-1243., Introduction: The organisation of aortic disease care has changed significantly in many countries over the last decade: centralized, high-volume centers were established., Objective: To analyse the perioperative mortality and the number of the infrarenal aortic aneurysm repairs according to the type of procedure (endovascular vs. open), patient volume (low vs. high) and time period (2010-2014 vs. 2015-2019)., Methods: The multicentric data registered prospectively in the Hungarian National Vascular Registry between 01. 01. 2010 and 31. 12. 2019 were analysed retrospectively., Results: 3206 infrarenal aortic aneurysms were recorded. The endovascular-open repair rate was significantly higher (p<0.0001) and the high-volume institutes managed significantly more ruptured aneurysms (p<0.0001) in the second period. The perioperative mortality of the open repair of ruptured aneurysms was significantly lower in the high-volume institutes than in the low-volume ones in the first period (p = 0.0011), and the mortality of endovascular repair was significantly lower compared with open repair in the high-volume institutes in the second period (p = 0.029). The perioperative mortality of the open repair of non-ruptured aneurysm was significantly lower in the high-volume institutes in both periods (p = 0.0007; p = 0.004). Furthermore, the mortality of endovascular repair was significantly lower compared with open repair both in the high- and the low-volume institutes in the second period (p<0.0001; p<0.0001). Patient volume (p = 0.006; p = 0.004), age (p<0.0001; p = 0.001), preoperative renal insufficiency (p = 0.007; p = 0.007) and the need of blood transfusion (p<0.0001; p<0.0001) were independent risk factors of the perioperative mortality of ruptured and non-ruptured aneurysms. Type of the procedure was also an independent risk factor in the case of non-ruptured aneurysms (p<0.0001)., Conclusion: Endovascular repair and aortic surgery in the high-volume institutes result in significantly lower perioperative mortality.
