"Squid-capture" modified in situ stent-graft fenestration technique for aortic arch aneurysm repair

An 83-year-old female was found to have an fusiform aneurysm in the aortic arch. She was deemed to be a high surgical risk; therefore, endovascular stent-graft placement followed by revascularization of the brachiocephalic trunk using in situ stent-graft fenestration was considered. However, the safe application of fenestration was deemed difficult due to the tortuosity of the brachiocephalic artery. The patient was successfully treated with the aid of the "squid-capture" technique, which consists of deployment of the stent-graft in a snare wire loop that was advanced from the brachiocephalic artery and fenestration of the stent-graft with the support of the loop. A follow-up exam revealed complete sealing of the aneurysm without any complications. The squid-capture technique allows for the safe and secure puncture of the graft.
