Initial Results of Thoracic Endovascular Repair with the Gore TAG Device Evaluated by the Japan SCORE System / 日本心臓血管外科学会雑誌

ABSTRACT

We report the initial results of thoracic endovascular repair using the Gore TAG device (TAG) used in treatment of thoracic aortic aneurysms (TAA), and evaluate initial outcome based on the Japan SCORE (JS) system. From August 2008 to July 2009, thoracic aortic endovascular repair (TEVAR) for TAA was applied in 27 cases (men/women, 22/5, 53-88 years old, mean age 70.5). Locations included the distal arch in 7 cases, proximal descending TAA (dTAA) in 12 cases and middle or distal dTAA in 8 cases. Deployment of a stent-graft (SG) was successful in 27 cases (100%) and complete thrombosis of the aneurysm or complete entry closure was achieved in 26 cases (96.3%). There was 1 type 2 endoleak (3.7%), 2 iliac arterial injuries (7.4%) and 2 cases of temporary hemodialysis (7.4%). There was no occurrence of paraplegia or hospital death. The 30-day mortality rate and major complication rate examined by the Japan SCORE (JS) system did not show any statistical differences between the TEVAR group and the open repair (OR) group, however the data were higher in the TEVAR group, although not statisfically in the OR group. The OR group had a high complication incidence in comparison with the TEVAR group. Based on evaluation by the JS system, the initial results suggest that TAG for the treatment of TAA is superior to conventional open surgery.
