Literature up to May 31, 2023 was searched and independently screened from 4 databases. Data were pooled for meta-analysis. Primary outcomes included intraoperative and follow-up endoleak, stent migration, and reintervention rates; sac regression; and 30-day all-cause mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Sixteen EVAR (n=1145) and 6 TEVAR studies (n=163) using the Heli-Fx EndoAnchor system were included from 2225 retrieved records. For EVAR patients (mean follow-up=11.9 months), the endoleak, graft migration, and reintervention rates were 3.97% (95% confidence interval [CI]=0.36%-1.99%), 0.004% (95% CI=0.00%-0.76%), and 5.43% (95% CI=0.86%-12.54%), respectively. The endoleak rates for primary and revision EVAR were 0.16% (95% CI=0.00%-1.65%) and 3.60% (95% CI=0.14%-9.72%), respectively. Only 4 cases of 30-day mortality (n=4) were reported in the literature. For TEVAR patients, the endoleak, stent migration, and reintervention rates were 7.4% (95% CI=0.03%-0.13%), 0.2% (95% CI=0.00%-0.06%), and 17.1% (95% CI=0.01%-0.45%), respectively.

Mortality in EVAR was low. The adjunctive deployment of endoanchors is an effective and safe means to prevent and treat endoleak and stent migration in EVAR and TEVAR. Yet, long-term efficacy and safety data and randomized controlled trials would be required to definitively recommend endoanchor use in routine clinical practice.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15266028241245911","type":"journal-article","created":{"date-parts":[[2024,4,17]],"date-time":"2024-04-17T02:10:41Z","timestamp":1713319841000},"page":"1889-1905","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Effectiveness and Safety of Endoanchors in Abdominal and Thoracic Endovascular Aneurysm Repair: A Systematic Review and Meta-analysis"],"prefix":"10.1177","volume":"32","author":[{"given":"Esther Wai Chi","family":"Tang","sequence":"first","affiliation":[{"name":"Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arthur Chak Kai","family":"Lau","sequence":"additional","affiliation":[{"name":"Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joshua Cheuk Hei","family":"Cheng","sequence":"additional","affiliation":[{"name":"Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6313-8099","authenticated-orcid":false,"given":"Joseph Chi-Yeung","family":"Wong","sequence":"additional","affiliation":[{"name":"Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6324-449X","authenticated-orcid":false,"given":"Yiu Che","family":"Chan","sequence":"additional","affiliation":[{"name":"Division of Vascular and Endovascular Surgery, Department of Surgery, Queen Mary Hospital, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,4,16]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2013.02.014"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2014.04.063"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2011.11.048"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2017.01.007"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/1526602818816099"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2016.12.117"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2018.07.080"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/1526602820923044"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12630-017-0974-1"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.semvascsurg.2012.09.002"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2021.03.010"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1177\/2048004019845508"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2019.05.006"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.12945\/j.aorta.2014.13-030"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.n71"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.283.15.2008"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1080\/15424065.2019.1691963"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13643-016-0384-4"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10654-010-9491-z"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.1177\/1708538121992596"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-0-387-09418-2"},{"key":"e_1_3_2_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2022.08.035"},{"key":"e_1_3_2_24_2","doi-asserted-by":"publisher","DOI":"10.1556\/650.2022.32449"},{"key":"e_1_3_2_25_2","doi-asserted-by":"publisher","DOI":"10.1177\/1708538120958837"},{"key":"e_1_3_2_26_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-020-02488-4"},{"key":"e_1_3_2_27_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.avsg.2019.01.017"},{"key":"e_1_3_2_28_2","doi-asserted-by":"publisher","DOI":"10.1055\/a-0746-3679"},{"key":"e_1_3_2_29_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.26351"},{"key":"e_1_3_2_30_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2014.02.017"},{"issue":"4","key":"e_1_3_2_31_2","first-page":"419","article-title":"The use of endoanchors in repair EVAR cases to improve proximal endograft fixation","volume":"53","author":"Avci M","year":"2012","unstructured":"Avci M, Vos JA, Kolvenbach RR, et al.
