Surgical conversion with graft salvage as a definitive treatment for persistent type II endoleak causing sacenlargement

2015

Objective The goal of this study was to present open surgical conversion with graft salvage or "semiconversion" as a definitive and safe treatment for untreatable and persistent type II endoleaks causing sac enlargement after endovascular aneurysm repair. Methods Between January 2001 and December 2014, 25 of 1623 endovascular aortic repair (EVAR) patients were selected as candidates for open semiconversion. The indication was persistent type II endoleak in 13 patients (12 of whom received previous attempts of embolization), type I and II endoleak in 2 patients, and sac growth without imaging evidence of endoleak in the other 10. After the infrarenal aorta was prepared (via a retroperitoneal…

Chimney and Periscope Grafts Observed Over 2 Years After Their Use to Revascularize 169 Renovisceral Branches in 77 Patients With Complex Aortic Aneu…

Purpose: To evaluate the performance of periscope and/or chimney grafts (CPGs) in the endovascular treatment of pararenal or thoracoabdominal aneurysms using off-the-shelf devices. Methods: Between February 2002 and August 2012, 77 consecutive patients (62 men; mean age 7369 years) suffering from pararenal aortic (n¼55), thoracoabdominal (n¼16), or arch to visceral artery aneurysms (n¼6) were treated with aortic stent-graft implantation requiring chimney and/or periscope grafts to maintain side branch perfusion. CPGs were planned in advance and were not used as bailout. A standardized follow-up protocol including computed tomographic angiography, laboratory testing, and clinical examination…

Type 1A endoleak detachable coil embolization after endovascular aneurysm sealing: Case report

2021

Introduction Endovascular aneurysm sealing (EVAS) with the Nellix system was introduced to reduce endovascular aneurysm repair (EVAR) perioperative complications, especially endoleaks. Herein we report a case of successful type 1A endoleak managed with detachable coils embolization after EVAS. Presentation of case A 77-year-old male was referred for abdominal pain. The angio-CT scan confirmed the previous EVAS procedure and showed a type Is2 endoleak below the right renal artery resulting in a 2.5 cm aortic blister with contrast medium filling the space between the aortic wall and the endobags. The patient was considered unfit for conventional open surgery and an endovascular approach with …

Trans-limb embolization for treatment of Type 2 endoleak post EVAR: Case report

2021

Introduction Type 2 endoleaks (T2EL) occur after 10%–25% of endovascular abdominal aortic aneurysm repairs and increase the risk factor of endograft repair failure and rupture. Herein we report a case of endovascular treatment of T2EL where we performed a trans-limb embolization. Presentation of case A 63-years-old male previously treated for AAA with endovascular aortic aneurysms repair (EVAR), showed an angio-CT scan followup with a type 2 endoleak fed from inferior mesenteric artery (AMI) with growth of AAA greater of 1 cm than preoperative CT-scan and increase of chronic lumbar pain. Due to high risk of rupture was performed a trans-limb embolization with complete sealing. The 6 months …

2020

Historically, chimney/snorkel endovascular aortic repair (Ch-EVAR) emerged as a rescue technique to revascularize and/or preserve inadvertently covered critical branch vessels during infrarenal aortic endografting. Next, in its evolutionary path, Ch-EVAR offered a viable treatment option for complex aortic repair, and particularly in situations where fenestrated/ branched EVAR was not a therapeutic option due to the lack of availability and/or anatomical constraints. In this context, this technique offered distinct advantages such as off-the-shelf availability, straightforward implantation techniques, and lower resource use-intensity enabling performance by a large number of operators manag…

Classification of Chimney EVAR-Related Endoleaks: Insights from the PERICLES Registry

2017

Juxtarenal aortic aneurysms (JAAs) pose significant challenges for endovascular aneurysm repair (EVAR). A short or absent infrarenal neck typically excludes standard EVAR as a viable or reasonable treatment option. In this context, the use of chimney grafts (chEVAR) is gaining in popularity and applicability. These grafts are designed to course in the aortic lumen outside the main stent-graft to maintain normal perfusion to the involved target branches. As such, they may represent a promising and less resource-intensive option for management of JAAs. However, this technical strategy is not without challenges of its own, particularly the inevitable creation of “gutters” that result from the …

Introduction: Type III endoleaks post-endovascular aortic aneurysm repair (EVAR) warrant treatment because they increase pressure within the aneurysm sac leading to increased rupture risk. The treatment may be difficult with regular endovascular devices. Endovascular aneurysm sealing (EVAS) might provide a treatment option for type III endoleaks, especially if located near the flow divider. This study aims to analyze clinical outcomes of EVAS for type III endoleaks after EVAR. Methods: This is an international, retrospective, observational cohort study including data from 8 European institutions. Results: A total of 20 patients were identified of which 80% had a type IIIb endoleak and the r…
