Novel retrieving device for coronary stent dislodgement
Abstract Background Stent dislodgement is a rare but particularly challenging complication. However, current treatment strategies are suboptimal.

| description | Abstract Background Stent dislodgement is a rare but particularly challenging complication. However, current treatment strategies are suboptimal. Objective This study sought to preliminarily assess the feasibility of a novel self-expanding basket (SEB) catheter to successfully retrieve dislodged stent during percutaneous coronary intervention (PCI). Method The novel SEB catheter is designed as a self-expanding basket tip made of superelastic shape nitinol memory alloy, which could automatically expand to tightly wrap and flatten the deformed struts regardless of whether the stent come off the guidewire. Consecutive patients with coronary artery disease who experienced stent dislodgement during PCI were included. The primary outcome was procedure success defined as completely removing the stent without surgical incision of blood vessels, or hemostatic forceps, or injury of access vessels. Results From May 2020 to May 2023, a total of 6 patients encountering stent dislodgment were enrolled. Five presented as stent dislodgment with the guidewire in situ and the rest one as total stent and guidewire loss. Successful retrieving of dislodged stent with SEB catheter was achieved in 100% (6 of 6) subjects. After retracting lost stent, 5 of 6 patients received new stent implantation, and one only underwent balloon angioplasty with acceptable imaging results. No safety events were observed. Conclusions This preliminary report of the novel stent retrieving device presents favorable efficacy and safety profile. Further multicenter study is required to confirm these findings. Clinical trial number Not applicable. |
