摘要
这项单中心研究调查了经动脉栓塞II型内漏对血管内主动脉修复术(EVAR)后动脉瘤囊扩张的安全性和有效性。2008年至2023年期间,36名患者(33名男性,75.9±6.6岁)共接受了50次血管内II型内漏栓塞手术。分析包括对患者风险概况、动脉瘤形态和内漏特征的评估。结果参数包括技术成功率(即先前灌注的动脉瘤囊完全无血流)和并发症发生率,而临床成功率则定义为随访期间无内漏持续或复发,动脉瘤无增大> 0.5 厘米。大多数介入治疗采用线圈栓塞(72%),少数仅使用液体栓塞剂(14%)。在最早的随访中,75.6%的病例可以证明没有持续性内漏,而内漏复发的无内漏率则低很多(46.3%)。经动脉栓塞是治疗 EVAR 后 II 型内漏的一种安全方法。经动脉栓塞术是EVAR术后治疗II型内漏的安全方法。虽然栓塞术在防止内漏复发导致动脉瘤进一步扩大方面效果一般,但大多数手术都成功地永久性消除了目标馈血管。- 经动脉栓塞治疗 II 型内漏的技术成功率很高。- 随着时间的推移,新的馈源血管的出现可能需要多次手术。- 患者的风险状况并不影响临床结果- Krompaß K、Grunz JP、Augustin AM 等人.血管内主动脉修复术后 II 型内膜漏经动脉栓塞疗法的技术和临床成功率分析.Fortschr Röntgen.Fortschr Röntgenstr 2024; DOI 10.1055/a-2384-4601.
Technical and clinical success analysis of transarterial embolization therapy in type II endoleaks following endovascular aortic repair.
This single-center study investigated the safety and efficacy of transarterial embolization of type II endoleaks for expanding aneurysm sacs following endovascular aortic repair (EVAR).36 patients (33 men, 75.9±6.6 years) underwent a total of 50 endovascular procedures for type II endoleak embolization between 2008 and 2023. Analyses included the assessment of patient risk profiles, aneurysm morphology, and endoleak characteristics. Outcome parameters comprised the technical success (i.e., complete lack of blood flow in the previously perfused aneurysm sac) and complication rates, while clinical success was defined as the absence of endoleak persistence or recurrence and freedom from aneurysm enlargement > 0.5 cm over the follow-up period.Transarterial embolization was technically successful in 84% of procedures with a complication rate of 2%. Most interventions were coil-based (72%), while a small number relied solely on liquid embolic agents (14%). Absence of a persisting endoleak in the earliest follow-up could be demonstrated in 75.6% of cases, whereas the absence rate for endoleak recurrence was substantially lower (46.3%). No aneurysm enlargement > 0.5 cm during follow-up was ascertained after 73.2% of interventions.Transarterial embolization represents a safe treatment for type II endoleaks after EVAR. While embolization was moderately effective in preventing further expansion of aneurysms due to endoleak recurrence, most procedures were successful in permanently eliminating the targeted feeder vessels. · Transarterial embolization of type II endoleaks has a high technical success rate.. · The emergence of new feeder vessels may necessitate multiple procedures over time.. · Patient risk profiles did not factor into the clinical outcome.. · Krompaß K, Grunz JP, Augustin AM et al.

期刊介绍:
Die RöFo veröffentlicht Originalarbeiten, Übersichtsartikel und Fallberichte aus dem Bereich der Radiologie und den weiteren bildgebenden Verfahren in der Medizin. Es dürfen nur Arbeiten eingereicht werden, die noch nicht veröffentlicht sind und die auch nicht gleichzeitig einer anderen Zeitschrift zur Veröffentlichung angeboten wurden. Alle eingereichten Beiträge unterliegen einer sorgfältigen fachlichen Begutachtung.
Gegründet 1896 – nur knapp 1 Jahr nach der Entdeckung der Röntgenstrahlen durch C.W. Röntgen – blickt die RöFo auf über 100 Jahre Erfahrung als wichtigstes Publikationsmedium in der deutschsprachigen Radiologie zurück. Sie ist damit die älteste radiologische Fachzeitschrift und schafft es erfolgreich, lange Kontinuität mit dem Anspruch an wissenschaftliches Publizieren auf internationalem Niveau zu verbinden. Durch ihren zentralen Platz im Verlagsprogramm stellte die RöFo die Basis für das heute umfassende und erfolgreiche Radiologie-Medienangebot im Georg Thieme Verlag.
Besonders eng verbunden ist die RöFo mit der Geschichte der Röntgengesellschaften in Deutschland und Österreich. Sie ist offizielles Organ von DRG und ÖRG und die Mitglieder der Fachgesellschaften erhalten die Zeitschrift im Rahmen ihrer Mitgliedschaft. Mit ihrem wissenschaftlichen Kernteil und dem eigenen Mitteilungsteil der Fachgesellschaften bietet die RöFo Monat für Monat ein Forum für den Austausch von Inhalten und Botschaften der radiologischen Community im deutschsprachigen Raum.
