Background: Coarctation of the aorta with poststenotic aneurysms is rare and complex. Here we report a relatively large group of endovascular treatments for the disease.
Materials and methods: Fifteen patients from two centers between 2006 and 2019 were included in the study. The patients were retrospectively divided into two groups. Patients in the complex group had insufficient proximal landing zone (<2 cm) or the zigzag shape of aorta. Their demographics, clinical manifestations, endovascular procedures, and follow-up results were analyzed.
Results: There were 7 patients in the simple group and 8 patients in the complex group. Eleven patients were symptomatic. Despite the unfavorable anatomy in the complex group, technical success reached 100%. The diameter of coarctation increased from 8.6 mm to 16.7 mm with poststenotic aneurysms successfully excluded at the same time. In patients without sufficient proximal landing zone, left subclavian artery was covered by the stent grafts and then sacrificed (three patients) or revascularized (four patients). Other than one patient who suffered iliac artery rupture and received open repair, there was no other perioperative complications. Computed tomography angiography repeated at mean 42 months postoperation confirmed patency of stents and the exclusion of aneurysms with no aortic wall injury. Mild endoleaks occurred in two patients in the complex group and were left to observation. During 55.0 months follow-up, except for one patient who received secondary left subclavian artery fenestration, all other patients remained asymptomatic.
Conclusions: Endovascular treatments for coarctation of the aorta with poststenotic aneurysm showed a high technical success and could be an alternative solution for such disease.
