[PMID: 38403184 DOI: 10.1016/j.ejvs.2024.02.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 02/07/2024] [Accepted: 02/22/2024] [Indexed: 02/27/2024]
Abstract
OBJECTIVE A multidisciplinary approach offering both open surgical repair (OSR) and complex endovascular aortic repair (cEVAR) is essential if patients with thoraco-abdominal aortic aneurysms (TAAAs) are to receive optimal care. This study reports early and midterm outcomes of elective and non-elective OSR and cEVAR for extent I - III TAAA in a UK aortic centre. METHODS Retrospective study of consecutive patients treated between January 2009 and December 2021. Primary endpoint was 30 day/in hospital mortality. Secondary endpoint was Kaplan-Meier estimates of midterm survival. Data are presented as median (interquartile range [IQR]). RESULTS In total, 296 patients (176 men; median age 71 years [IQR 65, 76]; median aneurysm diameter 66 mm [IQR 61, 75]) underwent repair (222 elective, 74 non-elective). OSR patients (n = 66) were significantly younger with a higher incidence of heritable disease and chronic dissection, while cEVAR patients (n = 230) had a significantly higher prevalence of coronary, pulmonary, and renal disease. Overall, in hospital mortality after elective and non-elective repair was 3.2% (n = 7) and 23.0% (n = 17), respectively, with no significant difference between treatment modalities (elective OSR 6.5% vs. cEVAR 2.3%, p = .14; non-elective OSR 25.0% vs. cEVAR 20.3%, p = .80). Major non-fatal complications occurred in 15.3% (33/215) after elective repair (OSR 39.5%, 17/43, vs. cEVAR 9.3%, 16/172; p < .001) and 14% (8/57) after non-elective repair (OSR 26.7%, 4/15, vs. cEVAR 9.5%, 4/42; p = .19). Median follow up was 52 months (IQR 23, 78). Estimated survival ± standard error at 1, 3, and 5 years for the entire cohort was 89.6 ± 2.0%, 76.6 ± 2.9%, and 69.0% ± 3.2% after elective repair, and 67.6 ± 5.4%, 52.1 ± 6.0%, and 41.0 ± 6.2% after non-elective repair. There was no difference in 5 year survival comparing modalities after elective repair for patients younger than 70 years and those with post-dissection aneurysms. CONCLUSION A multidisciplinary approach offering OSR and cEVAR can deliver comprehensive care for extent I - III TAAA with low early mortality and good midterm survival. Further studies are required to determine the optimal complementary roles of each treatment modality.

Abstract
PURPOSE To illustrate the technique of antegrade in situ laser fenestration (ISLF) on a predesign custom-manufactured stent-graft with single reinforced fenestration for use in emergency endovascular repair of complex abdominal aortic aneurysms (AAAs). TECHNIQUE A short custom-made device (CMD) fenestrated graft was predesigned with a single preloaded 8 mm strut-free fenestration at 12 o'clock position. A modified preloaded system was used to allow unilateral access from the distal port if necessary. After bilateral percutaneous femoral access, the graft was deployed under fusion guidance with the CMD fenestration matching the superior mesenteric artery (SMA) origin and immediately bridged as per standard technique. The aneurysm was then excluded with a bifurcated device. A large steerable sheath was used to allow for sequential antegrade laser in situ fenestration and stenting of the renal arteries. CONCLUSIONS Single-vessel customized short fenestrated grafts for the SMA and antegrade in situ laser renal fenestrations are technically feasible for repair of acute complex AAAs even after previous infrarenal reconstruction. It could become an off-the-shelf solution to limit aortic coverage and reno-visceral ischemia, even in patients with a narrow aortic diameter at the renal level. CLINICAL IMPACT Single-vessel precustomized short fenestrated grafts for the SMA combined with renal artery antegrade ISLF can be a feasible option for the acute repair of patients with complex aneurysms and a narrow aortic diameter at the reno-visceral segment. It may limit aortic coverage and reno-visceral ischemic time and also be applicable after previous infrarenal endovascular aneurysm repair (EVAR).

Abstract
OBJECTIVE To describe outcomes after elective and non-elective fenestrated-branched endovascular aortic repair (FB-EVAR) for thoracoabdominal aortic aneurysms (TAAAs). BACKGROUND FB-EVAR has been increasingly utilized to treat TAAAs; however, outcomes after non-elective versus elective repair are not well described. METHODS Clinical data of consecutive patients undergoing FB-EVAR for TAAAs at 24 centers (2006-2021) were reviewed. Endpoints including early mortality and major adverse events (MAEs), all-cause mortality, and aortic-related mortality (ARM), were analyzed and compared in patients who had non-elective versus elective repair. RESULTS A total of 2603 patients (69% males; mean age 72±10 year old) underwent FB-EVAR for TAAAs. Elective repair was performed in 2187 patients (84%) and non-elective repair in 416 patients [16%; 268 (64%) symptomatic, 148 (36%) ruptured]. Non-elective FB-EVAR was associated with higher early mortality (17% vs 5%, P <0.001) and rates of MAEs (34% vs 20%, P <0.001). Median follow-up was 15 months (interquartile range, 7-37 months). Survival and cumulative incidence of ARM at 3 years were both lower for non-elective versus elective patients (50±4% vs 70±1% and 21±3% vs 7±1%, P <0.001). On multivariable analysis, non-elective repair was associated with increased risk of all-cause mortality (hazard ratio, 1.92; 95% CI] 1.50-2.44; P <0.001) and ARM (hazard ratio, 2.43; 95% CI, 1.63-3.62; P <0.001). CONCLUSIONS Non-elective FB-EVAR of symptomatic or ruptured TAAAs is feasible, but carries higher incidence of early MAEs and increased all-cause mortality and ARM than elective repair. Long-term follow-up is warranted to justify the treatment.

The preservation of accessory renal arteries should be considered the treatment of choice in complex endovascular aortic repair. J Vasc Surg 2022; 76:656-662.

Abstract
OBJECTIVE To evaluate renal function and renal parenchymal length changes secondary to the coverage or preservation of accessory renal arteries (ARA) in complex aortic repair. METHODS Single-center retrospective study identifying all patients undergoing fenestrated or branched endovascular aortic repair (f-b EVAR) who present ARA. Two groups were created, a preserved ARA group, with incorporation of the vessel as a dedicated fenestration or branch in the endograft plan, and a non-preserved ARA group, without incorporation of them. Early >30% decline of glomerular filtration rate (GFR), kidney infarcts and endoleaks (EL) were evaluated. Mid-term results with freedom from kidney shrinkage (defined as length decrease > 10%) at follow-up, freedom from GFR decrease >30% or need for postoperative dialysis at follow-up were also analyzed. Primary assisted patency of incorporated ARA was calculated. RESULTS From 2011-2020, 145 patients undergoing complex aortic repair presented with an ARA. After excluding ruptured aneurysms, 33 patients had the ARA preserved with their incorporation into the stentgraft (preserved ARA group), and 99 did not have preservation of them (not-preserved ARA group). There were no statistical differences in demographics or type of aneurysm. Patients in the ARA-preserved group had more ARA (median of 2 per patient vs 1 in the non-preserved ARA group, p 0,01) and bigger ARA (median 4 vs 3 mm in the non-preserved ARA group, p 0,001).Early postoperative worsening >30% of GFR (23 vs 6%, p 0,03) as well as postoperative renal infarction (57% vs 6%, p 0,001) and ARA-related EL (20 vs 0%, p 0,01) were statistically higher for the not-preserved ARA group.Mid-term kidney length showed significant shrinkage in the not-preserved ARA group compared to the ARA preserved group (9,7 vs 0%, p 0,001). Freedom from >30% GFR decline at 2 years was significantly higher for the preserved ARA group (83% vs 47%, p 0,01).Two-years primary assisted patency of incorporated ARA was 94%. CONCLUSIONS In complex aortic repair incorporation of ARA is feasible, with low complications and good primary assisted patency at 2 years. It leads to less postoperative early renal dysfunction as well as higher freedom for mid-term renal disfunction and kidney shrinkage.

Abstract
Aortoiliac occlusive disease may limit the use of branched endovascular aneurysm repair (BEVAR) of thoracoabdominal aneurysms (TAAAs). Thus, infrarenal aortoiliac occlusion may preclude the use of BEVAR. We present a case involving a 67-year-old patient with a fast-progressing TAAA (diameter: 70 mm) and a concomitant total aortoiliac occlusion. A multi-staged treatment concept included the creation of the access and the distal landing zone for the consecutive endovascular procedures through an aorto-right femoral-left popliteal bypass. At six-week intervals, thoracic endovascular aortic repair for the creation of the proximal landing zone and a 4-vessel BEVAR were accomplished. At 36 months, a type III endoleak occurred due to the fracture of the bridging stent-graft to the celiac trunk and the superior mesenteric artery. It was successfully treated with VBX stent-grafts. This case illustrates the importance of a staged hybrid approach in the management of complex aortic pathologies with poor access and insufficient distal landing zone.

Abstract
OBJECTIVES Our goal was to report outcomes of the endovascular repair of urgent thoracoabdominal aortic aneurysms (TAAAs) using the Cook Zenith t-Branch off-the-shelf multibranched endograft. METHODS Between 2010 and 2020, we collected patients with TAAAs who received an urgent endovascular repair using the Cook Zenith t-Branch (had a rupture, symptoms or diameter >80 mm). Thirty-day mortality, spinal cord ischaemia (SCI) and clinical success were assessed as early outcomes. Freedom from reintervention, target visceral vessel patency and survival were considered during follow-up. RESULTS Sixty-five cases were managed using the Cook Zenith t-Branch for 27 (42%) TAAA ruptures, 8 (12%) symptomatic TAAAs and 30 (46%) asymptomatic TAAAs with a diameter >80 mm. Crawford's extent I-II-III and IV were noted in 54 (83%) and 11 (17%), respectively. Eleven (17%) patients had SCI with 3 (5%) cases of permanent paraplegia. Postoperative dialysis (P = 0.04) and ruptured TAAAs (P = 0.05) were associated with SCI. Sixteen (25%) patients had reinterventions within the first 30 days postoperatively. The 30-day mortality was 14% (9). Ruptured TAAAs (P = 0.05) and technical failures (P = 0.01) were correlated with in-hospital mortality. Clinical success was 78% (51 patients). The mean follow-up was 18 ± 14 months. Survival at 24 months was 47% with no late TAAA-related deaths. Patients with ruptured TAAAs had lower survival than those who did not have ruptured TAAAs (52% vs 60% at 1 year; P = 0.05). Target visceral vessel patency and freedom from reintervention at 24 months were 89% and 60%, respectively. CONCLUSIONS An off-the-shelf multibranched endograft is safe and effective for treating urgent TAAAs. Postoperative SCI and 30-day mortality are satisfactory for this challenging clinical scenario. The early reintervention rate is not negligible. Midterm survival is low, especially in patients with a ruptured TAAA; therefore, accurate patient selection is mandatory.

Abstract
We present a ruptured pararenal abdominal aortic aneurysm repaired with a complex three-vessel chimney EVAR . This technique allows for rapid sealing of the aneurysm with branch preservation and avoids complex open aortic surgery. This case report highlights techniques and pitfalls from complex three-vessel chimney EVAR repair in the emergency setting.

Abstract
PURPOSE To investigate feasibility and outcomes of endovascular repair for acute thoracoabdominal aortic aneurysms (TAAA). MATERIALS AND METHODS Data from a single center were retrospectively analyzed. Patients who underwent endovascular repair for acute TAAA between January 2010 and April 2020 were included. Perioperative and mid-term follow-up outcomes were analyzed. Survival, freedom from reintervention, and target vessel patency were calculated by Kaplan-Meier analysis. RESULTS A total of 30 patients (18 men, 67.5 ± 6.9 years) underwent endovascular repair for acute symptomatic (n = 15) or contained ruptured (n = 15) TAAA. An off-the-shelf four-branched stent-graft (T-Branch) was used in 19 (63.3%) patients, a custom-made device (CMD) with expedite order in 5 (16.7%) patients, a CMD with short anticipated delivery time in 3 (10.0%) patients, and a CMD available in the hospital in 3 (10.0%) patients. Technical success was 90.0% (n = 27). Thirty-day mortality was 10% (n = 3). There was no complete persistent paraplegia, but one (3.3%) patient suffered permanent limb weakness. Estimated survival at 1 and 2 years was 86.3% ± 6.4%, and 82.3% ± 7.2%, respectively. Estimated freedom from reintervention at 1 and 2 years was 81.4% ± 7.6% and 73% ± 8.8%. Estimated target vessel patency at 1 and 2 years was 96.6% ± 2% and 92.6% ± 2.9%. CONCLUSION Endovascular treatment of acute TAAA in this selected group of patients was associated with low early mortality and excellent mid-term survival. The off-the-shelf stent-graft option (T-Branch) was used in the majority of patients. Endovascular repair should be considered the first option for suitable acute TAAA.

Eur J Vasc Endovasc Surg 2021; 61:560-569. [PMID: 33589325 DOI: 10.1016/j.ejvs.2021.01.019] [Citation(s) in RCA: 36] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 01/01/2021] [Accepted: 01/13/2021] [Indexed: 12/19/2022]
Abstract
OBJECTIVE Physician modified stent grafts (PMSGs) present satisfactory results in selected cases of complex aortic pathologies. However, the technique lacks standardisation and depends on the surgeon and aortic segment. The aim of this article is to review comprehensively the technical details and clinical results of PMSGs related to patients with pathology in all aortic locations. METHODS A MEDLINE search (last search 20 April 2020) identified 20 relevant papers in the English language published over the last 20 years evaluating clinical outcomes after a PMSG and specifying the technical details to design it. RESULTS Seven hundred and eleven patients were included in the analyses, with 59% being operated on as an emergency. Ninety-two per cent of abdominal aortic segment PMSGs (A-PMSGs) were performed either as an emergency or before 2012. The main indications were available in 670 cases; 435 were degenerative aneurysms (64.9%) and 171 were aortic dissections (25.5%). Most of the endografts used were composed of polyethylene terephthalate, except for the Ankura (expanded polytetrafluoroethylene [Lifetech Scientific, Shenzhen, China]; n = 50, 7.5%). The Valiant (Medtronic, Minneapolis, MN, USA) represented 65% (n = 169) of aortic arch PMSGs (aa-PMSGs) and the Zenith platform (Cook Medical, Bloomington, IN, USA) 51% (n = 139) of A-PMSGs. A snare was used to reinforce the fenestration in 458 PMSGs (66%) and a cautery device cut the fenestration in 484 (75%) PMSGs. No bridging stent was used in 47 (7.0%) PMSGs (these aa-PMSGs had large fenestrations). Technical success ranged from 87.5% to 100% and 30 day mortality from 0% to 8%. Primary branch patency ranged from 96.3% to 100% at 12 month follow up. Zero to 14% of patients experienced type 3 or type 1 endoleak at 14.8 month follow up. CONCLUSION PMSG is a useful technique, particularly when validated treatments are not available. However, it is a non-standardised technique and the long term consequences of modifications remain unknown.

Abstract
Fenestrated and branched stent-grafts are being increasingly used to address complex pararenal and thoracoabdominal aortic aneurysms by endovascular means. The present paper describes the current indications, anatomical suitability and techniques of fenestrated and branched stent-grafts in the treatment for pararenal and thoracoabdominal aortic pathologies. Published outcomes with regard to perioperative mortality and morbidity, survival, reinterventions and target vessel patency during follow-up are also presented. Finally, advantages and disadvantages of endovascular repair as compared to open repair are discussed.

Abstract
Endovascular repair can be an alternative to conventional surgery for arch and thoracoabdominal aneurysms; however, it has the limits of available stent-grafts in anatomy. We present the case of an 87-year-old woman who had dual aneurysms in the arch and thoracoabdominal regions. We considered that traditional open surgery was of extremely high risk, because she was an octogenarian and had multiple comorbidities. We successfully treated the aortic arch aneurysm and the thoracoabdominal aortic aneurysm using endovascular stent-grafts in a high-risk patient who was a poor candidate for the conventional open surgery.

Abstract
Open surgical repair (OSR) for thoracoabdominal aortic aneurysms (TAAAs) is maximally invasive and associated with high rates of operative mortality and perioperative complications including spinal cord ischemia (SCI), despite improvements in surgical techniques and perioperative care. Elderly patients, patients with a history of aortic surgery, and patients with severe comorbidities are often considered ineligible for this surgery and endovascular treatment may be their only treatment option. Total endovascular aneurysm repair (t-EVAR) without debranching surgery does not require thoracotomy and laparotomy and could improve the outcomes of these patients. t-EVAR includes fenestrated EVAR (f-EVAR), multi-branched EVAR (b-EVAR), and physician-modified fenestration endograft (PMFG). Although these techniques have achieved lower mortality rates than OSR, there are concerns about perioperative complications including limb ischemia, SCI, and long-term outcomes such as endograft migration and endoleaks (ELs). This article provides an overview of available endovascular devices for TAAAs and reviews the short and mid-term results of t-EVAR, as well as alternative options.

Abstract
A 66-year-old man arrived at our emergency department 3 years after an endovascular aneurysm sealing procedure performed at another center. Computed tomography angiography showed distal migration of a Nellix endoprosthesis (Endologix, Irvine, Calif) and a posterior contained rupture. The left kidney was excluded by an occluded iliac-left renal bypass, which was performed at the time of the Nellix implantation because of unintended coverage. A t-Branch (Cook Medical, Bloomington, Ind) was implanted in an emergency, but the delivery caused disruption of the Nellix limb, requiring relining. Target vessels were bridged with VBX stents (W. L. Gore & Associates, Flagstaff, Ariz). The postoperative course was uneventful except for renal function impairment that was restored 2 weeks later.

Abstract
Aortic aneurysm (AA) is defined as an enlargement of the aorta greater than 1.5 times its normal size. Early diagnosis of AA is challenging and mortality of AA is high. Curative pharmacological treatments for AA are still lacking, highlighting the need for better understanding of the underlying mechanisms of AA progression. Accumulating studies have proven that the polarization state of circulating monocyte-derived macrophages plays a crucial role in regulating the development of AA. Distinct macrophage subtypes display different functions. Several studies targeting macrophage polarization during AA formation and progression showed potential treatment effects. In this review, we focus on the recent advances of research on macrophage polarization in the progression of AA and propose that targeting macrophage polarization could hold great promise for preventing and treating AA.
