| More Details: | Objective: To analyse case reports published on the latest generations of endograft (EG) and understand the mechanisms of type III endoleak (EL) development. Methods: A literature review was undertaken of English language case reports and series that concerned modular junction or component disconnection (type IIIa EL) and fabric perforations (type IIIb EL) after endovascular aneurysm repair. Results: Of the 2 785 studies, 56 full texts were chosen to review 73 cases. Type III EL was diagnosed with computed tomography angiography in 67.1% and digital subtraction angiography in 12.3%; the rest were identified during surgery. Of the 73 EG, 65 (89.0%) were made of polyethylene terephthalate and seven (9.6%) were polytetrafluoroethylene. The type of material was not mentioned in one (1.4%) case report. There were 25 (34.2%) type IIIa and 48 (65.8%) type IIIb EL. The most frequent were trunk–trunk in nine (12.3%) and trunk–limb overlap separations in 14 (19.2%). Type IIIb EL in the trunk area was identified in 27 (37.0%) cases, while 21 (28.8%) defects were found in the limbs. Stent fractures were recognised as an underlying mechanism of type IIIb EL development in one report. A combination of fabric lesions in the trunk and limb area was found in one case. Seven type IIIb EL were related to suture disruption or suture–fabric abrasions. Four cases were related to stent–fabric abrasions, and two developed as a result of fabric fatigue owing to kinking. Information on the mechanisms of degradation was only occasionally and scarcely presented. Given the small number of reports and lack of detailed analysis, no definitive conclusions could be drawn. Conclusion: The available information is scarce and does not allow any definitive conclusions to be drawn on the mechanisms that lead to the development of type III EL. Further explant analyses would be beneficial. |
