“…The flow diagram of the systematic search and selection is presented in Figure 3 . Finally, 21 papers (12 original articles, 9 case reports) were included; examination of the references did not produce additional records [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. None of the studies was randomized and none reported complete raw data, while some articles reported a selection of single-patient data; as a result, a meta-analysis could not be performed.…”

“…Five different ELIA approaches were described, the most used was transarterial embolization accessing the femoral artery (13/21, 62%) or the brachial/radial artery (6/21, 29%), two studies report on a percutaneous transabdominal approach [ 14 , 19 ], one on a translumbar approach [ 21 ] and two case reports on a transcaval approach [ 28 , 30 ].…”

Embolization for Type Ia Endoleak after EVAR for Abdominal Aortic Aneurysms: A Systematic Review of the Literature

et al. 2022

(1) Successful endovascular repair for abdominal aortic aneurysms is based on the complete exclusion of the aneurysm sac from the systemic circulation. Type Ia endoleak (ELIA) is defined as the persistent perfusion of the aneurysm sac due to incomplete proximal sealing between aorta and endograft, with a consequent risk of rupture and death. Endoleak embolization has been sporadically reported as a viable treatment for ELIA. (2) A systematic literature search in PubMed of all publications in English about ELIA embolization was performed until February 2022. Research methods and reporting were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Data regarding patient numbers, technical success (endoleak absence at control angiography), reinterventions, clinical and imaging follow-up, and outcomes were collected and examined by two independent authors. (3) Twenty-one papers (12 original articles, 9 case reports) reported on 126 patients (age range 58–96 years) undergoing ELIA embolization 0–139 months after the index procedure. Indication for embolization was most often founded on unfavorable anatomy and patient comorbidities. Embolic agents used include liquid embolic agents, coils, plugs and combinations thereof. Technical success in this highly selected cohort ranged from 67–100%; the postprocedural complication rate within 30 days was 0–24%. ELIA recurrence was reported as 0–42.8%, with a secondary ELIA-embolization-intervention success rate of 50–100%. At a follow-up at 0–68 months, freedom from sac enlargement amounted to 76–100%, freedom from ELIA to 66.7–100%. (4) Specific literature about ELIA embolization is scant. ELIA embolization is a valuable bailout strategy for no-option patients; the immediate technical success rate is high and midterm and long-term outcomes are acceptable.

“…Finally, a total of ten eligible studies were included for analysis; review of the references yielded no additional studies. (18)(19)(20)(21)(22)(23)(24)(25)(26)(27) No meta-analysis could be performed since none of the included studies were randomized trials nor were there control groups reported.…”

“…These ten studies described 194 patients who received liquid embolics as the sole treatment for T1EL after EVAR. (18)(19)(20)(21)(22)(23)(24)(25)(26)(27), 9 (4.6%) patients received treatment for ruptured aneurysms, in six cases initial EVAR for a ruptured aneurysm was directly followed by embolization of the T1EL. (18, 22, 23) Ierardi et al described three patients treated for secondary aneurysm rupture after EVAR caused by a late T1EL, for which embolization was performed.…”

“…Moreover, in this situation there is always a certain risk of Onyx reflux. 25 Endoanchors are designed to enhance endograft proximal fixation and sealing. The ANCHOR registry compared the prophylactic use of the anchors with their use in the treatment of proximal aortic neck complications and found better technical success (absence of a type Ia endoleak at completion angiography) for the former (89.7% vs 80.5%, respectively).…”

Transcatheter Embolization of Type I Endoleaks Associated With Endovascular Abdominal Aortic Aneurysm Repair Using Ethylene Vinyl Alcohol Copolymer

Abstract: Type I endoleaks can be safely and effectively treated by embolotherapy with EVOH. Larger endoleaks resulting from grossly undersized endografts appear to be unsuitable for EVOH embolization.
