Gore C-TAG stent-graft segmented release combined with periscope technique for distal reentry tear after thoracic endovascular aortic repair for Stanford B aortic dissection / 中华普通外科杂志

ABSTRACT

Objective:To assess the clinical value of Gore C-TAG stent-graft segmented release mode combined with 'periscope’ technique in dealing with distal reentry tear of aortic dissection after thoracic endovascular aortic repair (TEVAR).Methods:The clinical data of 5 patients of distal false lumen enlargement after thoracic endovascular aortic repair for Stanford type B aortic dissection (TBAD) from 2019 to 2020 was retrospectively analyzed.Results:All five patients were male. Combining Gore C-TAG stent-graft segmented release mode with 'periscope’ technique was used. All five patients successfully underwent secondary endovascular repair, no intraoperative thoracotomy or major postoperative complications during hospitalization occurred . Compared to aortic CTA imaging in pre- and post-secondary endovascular repair, the curative efficacy of this method in the treatment of distal reentry tear of aortic dissection was evaluated. It showed that distal reentry tears were covered completely without reperfusion of aortic false lumen, as well as branch stents with well-perfusion based on aortic CTA imaging during the first year following-up.Conclusions:Gore C-TAG stent-graft segmented release mode combined with 'periscope’ technique in dealing with distal reentry tear of aortic dissection is technically applicable and highly successful with satisfactory short-term results.
