- Abstract
- Three patients suffered endoleaks after thoracic endovascular aortic repair (TEVAR). The type 1 endoleak were treated by direct transcutaneous puncture embolization (DTPE) after failure of conventional endovascular methods of repair. The type 2 endoleak was treated initially by DTPE in a symptomatic patient with expansion of the aneurysmal sac after conservative observation. Coils and/or Onyx copolymer were used as embolic agents for DTPE. A technically successful repair of the endoleak was accomplished in all three patients. Paragraph Headings： 1. Introduction 2.

A 64-year-old female suffered from aortic arch aneurysm and underwent aortic arch total debranching combined with TEVAR. She complained persistent chest pain and type 2 endoleak with aneurysm sac expanding was revealed by serial CTA. 2. Under CT/3D navigation guidance, an 18G needle positioned co-axially with a 21G Chiba needle was inserted directly into the aneurysmal sac. CT was used to assure the correct navigation of the needle into the endoleak sac to avoid injury to the pulmonary parenchyma and esophagus (Figure 2a and 2b). Successful puncture of the endoleak sac was confirmed by backflow of blood from the needle and by sacography in which the endoleak could be visualized (Figure 2c) 3. Follow up CTA revealed no endoleak was noted with aneurysm sac shrink and the patient keep asymptomatic
