Dislodged Coronary Artery Stent Retrieved With an Endovascular Snare

Abstract

Advances in stent design and technology have made stent loss during percutaneous coronary intervention rare. When stent loss occurs, the risk of life-threatening procedural complications is high. We describe the use of an endovascular snare system to retrieve a dislodged stent from the proximal right coronary artery of a 54-year-old man during percutaneous coronary intervention after other conventional retrieval techniques had failed.

PThe Case of Removal of Intracoronary Broken Stent Catheter’s Shaft and Its Balloon Trough Femoral Sheat During Primer PTCA

“…Various stent retrieval techniques have been described in the literature in case of stent loss (or dislocation). These include loop snare, endovascular snare device, and forceps, twisting guide wire technique, small angioplasty balloon, and basket retrieval apparatus or pressing the stent toward the wall of the blood vessel by a balloon [5,6]. In our case, we performed successful retrieval using Amplatz Goose Neck™ Snare Kit (GN 1000)…”

“…Many risk factors have been supposed to predispose coronary SF. coronary calcification, ostial stent location, abnormal forces that concentrate on the struts and lead to metal fragility, tortuosity (especially in RCA), overlapping of stents, increase in stent length, dynamic movement of the vessel during repetitive cardiac contractions and consequently exposure to distortion forces, coronary ectasia / aneurysm and balloon over dilation are some of these factors [5,6].…”

A case report of fractured guidewire removal by rotational atherectomy

“…It is composed of three cable metal rings and can firmly grasp and safely remove the broken guidewire. The platinum wire wrapped around each ring can enhance the angiographic effect [ 7 ]. If the patient worsens and develops hemodynamic instability, surgical treatment should be considered to completely remove the guidewire.…”

When an interventional cardiologist needs to be a vascular surgeon: Successful management of coronary stent loss in a nonagenarian

“…Interventional cardiologists should be familiar with a range of stent retrieval techniques. If they fail, interven-tional cardiologists must think creatively and be prepared to apply all equipment and expertise accessible in the cath lab to optimize the odds for positive outcomes and sometimes even use techniques reserved for vascular surgeons [3]. One must also remember that presently, with new-generation drug-eluting stents, there is a possibility to take a stent with a smaller nominal diameter (e.g., 3.5 mm) and easily postdilate it to the diameter of 4.5 and even 5.00 mm.…”
