A Case of Entrapped Rotablator Burr and Possible Mechanism of Entrapment: Insight from Intravascular Ultrasound Findings
نویسندگان
چکیده
The effectiveness of rotational atherectomy as the primary strategy for complex, severe calcified lesions has been established for facilitating device delivery, optimal stent expansion, and good apposition [1-6]. However, the rotablator carries the potential for life-threatening complications. Flow complications, including slow flow/no reflow, coronary perforation, and dissection, are well known. However, rotablator burr entrapment [7-15] is a rare complication of rotational atherectomy, estimated to occur in 0.4% of cases [3]. Herein, we report a case of this rare complication treated with successful retrieval of the entrapped rotablator by balloon inflation after the insertion of a second guide wire. Furthermore, we discuss the mechanism responsible for the burr entrapment based on lesion characteristics obtained from intravascular ultrasound (IVUS) findings.

Successful Retrieval of an Entrapped Rotablator Burr by Using a Guideliner Guiding Catheter and a Snare.
Although burr entrapment is a rare complication of rotablation, it is extremely difficult to retrieve a stuck entrapped burr without surgical intervention. There are several techniques typically employed to retrieve an entrapped burr, using bailout endovascular approaches. Herein we have presented a new retrieval method involving a Guideliner child-in-mother catheter combined with a snare, whic...
متن کاملMechanism and management of burr entrapment: A nightmare of interventional cardiologists
Entrapment of the burr within calcified lesion is an uncommon, but serious complication during rotational atherectomy and usually needs surgical retrieval. We report a case series of this complication and also review the possible mechanisms, such as kokesi phenomenon or insufficient pecking motion with decreased rotational speed. We also review the potential techniques ever proposed to rescue t...

In June 2012, Food and Drug Administration (FDA) issued a warning about the risk of catheter entrapment associated with Onyx embolization. We used our experience, literature review, and FDA Manufacturer and User Facility Device Experience (MAUDE) data review to identify five strategies to address catheter entrapment: 1/. Surgical resection of vessel at point of entrapment of catheter and retrac...
متن کاملIs rotational atherectomy here to stay?
Rotational atherectomy was developed to ablate selectively inelastic atherosclerotic plaque, while deflecting normal arterial wall away from the rotating burr. Intravascular ultrasound (IVUS) studies have confirmed that rotablation differentially removes even hard, calcified plaque without damaging normal arterial wall. Early in clinical experience, the ability to ablate previously undilatable ...
متن کاملA case of an entrapped rotational atherectomy burr.
Rotational atherectomy is a widely used modality in percutaneous coronary revascularization, especially for heavily calcified coronary arteries [1–5]. Due to the unique mechanism of rotational atherectomy, there have been reports of unusual complications, including fracture of coronary wire, guidewire bias, coronary spasm leading to myocardial infarction, and fracture of the drive shaft causing...
