“…The appropriate surgical technique for COA repair often remains unclear for adult patients 10 . Surgical techniques to treat COA include resection with end-to-end anastomosis, prosthetic patch aortoplasty, subclavian flap aortoplasty, interposition grafting and extra-anatomic bypass grafting 2 , 4 , 11 , 12 .…”

“…Extra-anatomical bypass grafting has been recommended for complex COA cases (COA coexists with the other valvular, vascular and ventricular diseases) 4 , 5 , 10 , 12 – 15 as well as isolated COA cases (COA does not coexist with the other cardiovascular pathologies) 11 , 12 in adults. Furthermore, surgical treatment for COA carries some risk for spinal cord injury, occurring in approximately 0.5% of patients being operated on for coarctation 16 , studies have shown that extra-anatomic bypass minimizes the risk of paraplegia 2 , 15 .…”

Accurate hemodynamic analysis is not only crucial for successful diagnosis of coarctation of the aorta (COA), but intervention decisions also rely on the hemodynamics assessment in both pre and post intervention states to minimize patient risks. Despite ongoing advances in surgical techniques for COA treatments, the impacts of extra-anatomic bypass grafting, a surgical technique to treat COA, on the aorta are not always benign. Our objective was to investigate the impact of bypass grafting on aortic hemodynamics. We investigated the impact of bypass grafting on aortic hemodynamics using a patient-specific computational-mechanics framework in three patients with COA who underwent bypass grafting. Our results describe that bypass grafting improved some hemodynamic metrics while worsened the others: (1) Doppler pressure gradient improved (decreased) in all patients; (2) Bypass graft did not reduce the flow rate substantially through the COA; (3) Systemic arterial compliance increased in patients #1 and 3 and didn’t change (improve) in patient 3; (4) Hypertension got worse in all patients; (5) The flow velocity magnitude improved (reduced) in patient 2 and 3 but did not improve significantly in patient 1; (6) There were elevated velocity magnitude, persistence of vortical flow structure, elevated turbulence characteristics, and elevated wall shear stress at the bypass graft junctions in all patients. We concluded that bypass graft may lead to pseudoaneurysm formation and potential aortic rupture as well as intimal hyperplasia due to the persistent abnormal and irregular aortic hemodynamics in some patients. Moreover, post-intervention, exposures of endothelial cells to high shear stress may lead to arterial remodeling, aneurysm, and rupture.

Aim: We present a case of successful endovascular repair of late ruptured aortic anastomotic pseudoaneurysm following previous left subclavian artery–descending thoracic aorta bypass and concomitant emergency thoracic endovascular aortic repair (TEVAR) of complicated endovascular aortic de-coarctation never previously described is also presented. A review of the intraoperative, 30-day, and follow-up morbidity, mortality, and complications of TEVAR as endovascular treatment of late aneurysm/pseudoaneurysms after surgical aortic de-coarctation was also performed. Methods: The systematic review was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement and following PICO model. A literature search was conducted on MEDLINE, PubMed, EMBASE, Cochrane Library, Google Scholar, Science Direct, and Web of Science using the words “tevar of late complication of aortic coarctation surgical repair” and “endovascular repair of anastomotic pseudoaneurysm in coarctation” up to June 17, 2022. Data were extracted from study documents about study design, patient’s demographics and comorbidities, details about primary surgical repair, type of late complication, time between open surgery and occurrence of complications, details of the secondary endovascular procedure with technical success, early, and follow-up mortality and morbidity. Results: A total of 18 papers were included with 78 patients (48 men, 69.5%). The most frequent type of primary open surgical repair was patch aortoplasty (46, 58.9%). Focusing on aneurysm and pseudoaneurysm as late complications, most of the patients were asymptomatic (45, 57.7%). All patients underwent TEVAR, 14 of them (17.9%) in urgent/emergent setting. The technical success was 98.7%, with 1 intraoperative death due to rupture of the aorta. In total, 31 patients out of 78 (39.7%) showed different complications in the immediate postoperative time, with type II endoleak being the most observed (8/31, 25.8%). The mean follow-up time was about 2 years (26.5 months, range 3–92). Overall, 30-day mortality was 2.6%. Complications occurred in 30 patients (39.4%), 23 of them resolved during the follow-up period. Conclusions: With the limit of low-quality data, TEVAR can be considered a safe and effective option for the treatment of late complications after open surgery for aortic coarctation, even in urgent settings. Clinical Impact Different specialists have to face the technical complexities and risks related to treatment of late complications after surgical de-coartaction, which can be either surgical or endovascular, and depend on patient’s ages. Although covered stents appear to have some protection from the development of stent fractures, doesn’t provide complete protection from late aneurysm formation. In this setting, TEVAR may represent a valuable option, combining the advantages of the covered stent with those of a device that can cover a wider range of aortic length, especially in adult patients. This study shows thoracic endovascular repair can be considered a safe and effective option in clincal practice for the treatment of late complications after open surgery for AC, even in urgent settings.
