This study aimed to investigate the efficacy and safety of salvage endovascular septectomy in patients with abdominal chronic aortic dissection (CAD) after endovascular aneurysm repair. A study cohort comprising 6 patients with chronic abdominal aortic dissection after failed endovascular aortic repair [mean age 62.5 (36-69) years] were enrolled to undergo salvage endovascular septectomy. The procedure involved entering the false lumen via the intrinsic visceral entry to perform a confined septectomy using a 'Gigli wire' to merge the true and false lumens. The outcomes were assessed by Digital angiography and computed tomography angiography. All 6 patients were successfully operated on; the diameters of the visceral abdominal aorta and the infrarenal abdominal aorta were similar at 1, 3, 6 and 12 months compared with the baseline; the patency of the visceral branch arteries was also stable at 1, 3, 6 and 12 months compared with the baseline; no occlusion of the visceral branch arteries was noted; no major vascular adverse events or deaths were observed. In this preliminary study, it was proven that salvage endovascular septectomy is a potentially advantageous technique that is safe and effective in the treatment of patients with CAD after failed endovascular aortic repair.
