Re-TEVAR in treatment of stent graft-induced new entry between two non-overlapping stent-grafts: a case report

Abstract

Background Progress of the aortic disease after the stent graft treatment of aortic dissection implicates the potential risks of stent graft-induced new entry (SINE). Although rarely reported, it should be vigilant in patients who might incur serious complication in early period after the thoracic endovascular aortic repair (TEVAR). Thus, the development of aortic disease-specific stent grafts would assist in achieving positive patient outcomes when suffering SINE. However, it is an extremely rare for SINE between two non-overlapping stent-grafts. Case presentation We here reported a 59-year-old male patient with sudden onset of chest pain for 4 h. Multi-detector computed tomography (MDCT) revealed a huge SINE formed between two non-overlapping stent-grafts. The re-TEVAR surgery was performed and the patient experienced a good recovery. Conclusion The SINE between two non-overlapping stent-grafts treated by re-TEVAR operation was alternative and feasible. The short-term and medium-term follow-up results were satisfactory.

“…In the chronic phase, however, the intimal membrane is thicker and more fibrotic than in acute aortic dissection. For this reason, the expansile force of the stent graft persistently injures the rigid true lumen [ 4 ]. The intima can then ultimately develop new intimal tears, resulting in aortic dissection.…”
