| Introduction|| |
As interventional cardiology era has been improving and advanced percutaneous coronary interventional procedures have been increasingly performed worldwide, operators might be confronted with some complications. We report a case of coronary stent delivery catheter breaks and its successful retrieval, and we review the literature in this regard.
| Case Report|| |
A 73-year-old male patient was admitted to the emergency department with unstable angina pectoris. After his medical therapy was initiated, diagnostic coronary angiogram was performed. Coronary angiogram revealed a critical stenosis of obtuse marginal branch of the left circumflex artery. Percutaneous intervention to the obtuse marginal branch of the left circumflex artery was mandatory.
The procedure started with punction of the left common femoral artery, which was extremely tortuous. After obtaining a successful vascular access, the left main coronary artery was cannulated by a 6-French (6F) EBU guiding catheter (Medtronic Inc., Minneapolis, MN, USA). The patient was anticoagulated by administration of 100 U/kg unfractional heparin (UFH). Then, the operator passes through the critical stenosis by instrumentality of a soft 0.014-inch CHOICE floppy coronary guidewire (Boston Scientific, Marlborough, MA, USA). Subsequently, the critical stenotic lesion was predilated successfully with a 2.0 mm × 20 mm predilation balloon (Invader, Alvimedica Medical Technologies, Turkey) at 12 atmospheric (atm) pressure. Following successful predilation, the operator decided to proceed to the next step, which was implantation of a drug-eluting coronary stent (PROMUS Element, Boston Scientific, Marlborough, MA, USA). Although the whole delivery catheter was inside the guiding catheter, the stent did not reach the critical lesion. Suddenly, it was realized that while it was pushed forward, the delivery catheter broke into halves in the guiding catheter because of the extremely tortuous vascular access. One of the broken parts of the delivery catheter was totally inside the body, and the other part was partially in the guiding catheter and its hub was out of the guiding catheter. The operator pulled back the distal part of the broken delivery catheter out of the body [Figure 1]. After that, a 2.5 mm × 20 mm coronary predilation balloon catheter (Invader, Alvimedica Medical Technologies, Turkey) was inserted into the guiding catheter and passed by the proximal half of the broken stent delivery catheter. By the help of inflation coronary balloon inside of the guiding catheter, the broken part of the stent delivery catheter was trapped inside of the guiding catheter between the predilation balloon and the guiding catheter wall [Figure 2]. It was achieved by withdrawal of the broken part of stent delivery catheter into the guiding catheter by trapping and pulling back the inflated predilation balloon repetitiously [Figure 2]. Just after being sure that the broken part of the catheter was totally in the guiding catheter, all the system was pulled out of the body. After the successfully management of this complication, the left main coronary artery was engaged by a new EBU guiding catheter (Medtronic Inc., Minneapolis, MN, USA). The procedure was continued by crossing the critical stenotic lesion. Finally, a 3.0 mm × 38 mm drug-eluting coronary stent (PROMUS Element, Boston Scientific, Marlborough, MA, USA) was implanted successfully, and the procedure was terminated without any complication.

| Discussion|| |
Inadvertent retention of coronary hardware such as guidewire, stent or balloon delivery catheter, distal part of atherectomy devices, or dislodged coronary stents due to entrapment or catheter break is very uncommon complication, which leads to myocardial ischemia or infarction, vascular tissue injury, and even death, during percutaneous coronary interventions. Management of such complication requires additional intervention such as surgical or percutaneous intervention. There are several established several retrieval methods for overcoming this unwanted complication with regard to percutaneous intervention. These methods can be summarized as small balloon technique, two-wire technique, snares, forceps, retrieval baskets, specific retrieval devices, and distal embolic protection devices. Despite these well-established techniques, compensation for such complication can be very challenging sometimes.
In the literature, there are several case reports, including different clinical scenario and various implementation of retrieval technique [Table 1]. Wani et al. reported a case of stent delivery catheter break during percutaneous coronary angioplasty. In this case, the complication was successfully managed by compression of the fractured part of the delivery catheter in the guiding catheter by balloon trapping and removing the entire system out of the body. In the literature, there are several similar cases.,,,,, Another retrieval method was mentioned by Chan et al. In the course of balloon dilation of side branch ostium after main vessel stent deployment, the shaft of balloon catheter accidentally broke, and Chan et al. retrieved the broken part of the catheter by means of using an alligator forceps. An alternative approach for retrieval the foreign bodies in coronary circulation is balloon-supported catheter-assisted retrieval technique. Kunwar et al. made a success of restraining of the broken part of balloon catheter between guiding catheter and dilation balloon, followed by ensheathing this broken part into the guiding catheter. A relatively simple method, which was gently withdrawing the entire system as a unit without any additional technique was applied by O'Neill et al. In another complicated case, after failed attempts by using snare, two-wires and balloon techniques to remove a broken intravascular ultrasound catheter in the coronary vasculature, Chang et al. achieved to remove it by the help of using distal embolic protection device. Vimal Mehta et al. achieved to retrieve the distal portion of a broken thrombectomy catheter by means of guiding catheter-supported balloon inflation and pulling-back technique. Similar problems might emerge during advanced percutaneous coronary interventions as well. Imamura et al. reported a case of Rotablator® (Boston Scientific, Marlborough, MA, USA) driveshaft fracture and retrieval of entrapped burr by means of squeezing between inflated balloon and GuideLiner® (Japan Lifeline, Tokyo, Japan) and pullback into the guiding catheter.
Sometimes, operators can be encountered similar complications during percutaneous peripheral vascular interventions. Gürbüz et al. experienced and reported such a complication which occurred after peripheral vascular intervention. In this case report, a broken self-expandable peripheral stent cateheter was retrieved succesfully by a techique which icluded a loop snare combined with an inflated balloon.
Consequently, until recently, several retrieval methods have been applied, but none of these methods are like our retrieval technique. On the basis of literature review, our technique, which is balloon trapping and withdrawing the broken hardware and getting it into the guiding catheter before pulling back the whole system, is a unique technique and till now this method is never reported in the interventional era. This method might be safer than other techniques because the broken catheter is completely in the guiding catheter while pulling all systems out of the body. Finally, this method should always be kept in mind in case of a similar complication.
