Objective: The formation of postaortic coarctation aneurysms (pCoAA) is well-described in the literature and carries a significant risk of rupture and death. Treatment strategies include open surgical, hybrid, and endovascular repair, depending on the clinical presentation, risk assessment, and anatomy. The aim of this study was to report the early and midterm results of open surgical and endovascular repair of pCoAA. Methods: This is an international multicenter retrospective study including patients who underwent open surgical or endovascular repair for pCoAA between 2000 and 2021 at 14 highly specialized academic cardiovascular centers. The preoperative, intraoperative, and postoperative data were recorded and analyzed. Results: A total of 74 patients (46 male; median age, 44 years; interquartile range [IQR], 35-53 years) underwent pCoAA repair. All patients had previously undergone surgical repair of aortic coarctation at a median age of 11 years for the index procedure (IQR, 7-17 years). The most common first surgical correction was synthetic patch aortoplasty in 48 patients, followed by graft interposition in 11. The median pCoAA diameter was 54 mm (IQR, 44-63 mm). The median time from the aortic coarctation repair to the pCoAA diagnosis was 33 years (IQR, 25-40 years). A total of 33 patients had symptoms at presentation, including thoracic or back pain in 8 patients. Open surgical repair was performed in 28 patients, including four frozen elephant trunk procedures and one Bentall. The remaining 46 patients underwent endovascular repair of the pCoAA. Two in-hospital deaths were observed (one frozen elephant trunk and one endovascular). After a median follow-up of 50 months (IQR, 14-127 months), there were a total of seven reinterventions. Conclusions: This international multicenter study demonstrates that patients with pCoAA can be safely treated with either open surgical or endovascular interventions. Because the median time between the coarctation repair and the aneurysm formation was more than 30 years, life-long surveillance of these patients is warranted.

Abstract

Objective: The formation of postaortic coarctation aneurysms (pCoAA) is well-described in the literature and carries a significant risk of rupture and death. Treatment strategies include open surgical, hybrid, and endovascular repair, depending on the clinical presentation, risk assessment, and anatomy. The aim of this study was to report the early and midterm results of open surgical and endovascular repair of pCoAA. Methods: This is an international multicenter retrospective study including patients who underwent open surgical or endovascular repair for pCoAA between 2000 and 2021 at 14 highly specialized academic cardiovascular centers. The preoperative, intraoperative, and postoperative data were recorded and analyzed. Results: A total of 74 patients (46 male; median age, 44 years; interquartile range [IQR], 35-53 years) underwent pCoAA repair. All patients had previously undergone surgical repair of aortic coarctation at a median age of 11 years for the index procedure (IQR, 7-17 years). The most common first surgical correction was synthetic patch aortoplasty in 48 patients, followed by graft interposition in 11. The median pCoAA diameter was 54 mm (IQR, 44-63 mm). The median time from the aortic coarctation repair to the pCoAA diagnosis was 33 years (IQR, 25-40 years). A total of 33 patients had symptoms at presentation, including thoracic or back pain in 8 patients. Open surgical repair was performed in 28 patients, including four frozen elephant trunk procedures and one Bentall. The remaining 46 patients underwent endovascular repair of the pCoAA. Two in-hospital deaths were observed (one frozen elephant trunk and one endovascular). After a median follow-up of 50 months (IQR, 14-127 months), there were a total of seven reinterventions. Conclusions: This international multicenter study demonstrates that patients with pCoAA can be safely treated with either open surgical or endovascular interventions. Because the median time between the coarctation repair and the aneurysm formation was more than 30 years, life-long surveillance of these patients is warranted.
