A total of 10 cases (8 males) were included. The mean age was 54.5\u00b114.2 years (range: 31\u201380 years). Eight cases presented as aneurysm rupture or impending rupture accepted emergency repair. Technical success, defined by placement of all endografts as planned, was achieved in all cases. A total of 30 target visceral branches were successfully cannulated, 9 celiac arteries were covered intentionally. Intraoperative endoleak was observed in 6 patients, all of them were gutter leak. During hospital stay, there was no death, no side branch occlusion or spinal cord ischemia. Median follow-up was 30 months (range: 12\u201350 months). One patient died of lung cancer at 14-month follow-up. There was no secondary endoleak. The primary endoleak were found spontaneously resolved in 3 cases at 7 days, 3-month, and 1-year imaging. One persistent endoleak totally resolved after sealing of gutter spaces at 4-month follow-up. The other 2 persistent endoleak decreased during follow-up, which are still under observation. The branch patency rate was 90.3% (28\/31). All the 3 occluded branches were renal arteries. Branch occlusion occurred in 2 cases at 1-month follow-up and 1 case at 2-year follow-up, but renal insufficiency was not observed in these cases. Obvious aneurysm sac shrinkage (\u22655 mm) was observed in all cases. The aneurysm size shrunk from 7.6\u00b11.9 to 5.5\u00b11.4 cm. No spinal cord ischemia occurred during follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Treatment of ruptured TAAA and PRAAA with \u201cOctopus\u201d technique is feasible and safe for high surgical risk patients in the absence of fenestrated and branched devices.
