Abstract: We report the case of a 76-year-old man who developed type IA endoleak through the fenestration after 1-debranch TEVAR using a Najuta endograft. The patient was admitted with expansion of the aneurysm after TEVAR, for additional therapy. Type IA endoleak through a fenestration has remained a significant clinical concern and its treatment is challenging. We performed Zone 0 TEVAR using the “Squid-Capture” technique assisted in situ stent-graft fenestration. Cerebral vessels were perfused by a percutaneous cardiopulmonary support system during in situ stent-graft fenestration, and the cerebral branch was clamped at the proximal site. It is difficult to operate the catheter inside the endoskeleton structure of a Najuta endograft, but several innovations were effective. Test dilation of the balloon catheter was performed to ensure that the wire did not interfere with the endoskeleton. Avoiding interference with the endoskeleton is important. The Squid-Capture technique allows safe and secure puncture of the graft. The operation was completed successfully. After this procedure, the endoleak disappeared. It is considered to be a useful method for treatment of endoleak through the fenestration.
