Inadvertant balloon extrusion through a side hole in a guiding catheter
Insights
A patient experienced a myocardial infarction successfully treated with streptokinase and angioplasty. A complication occurred when the balloon catheter extruded through the guiding catheter's side hole during angiography.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Device Technology
Background:
- Acute myocardial infarction requires prompt reperfusion therapy.
- Coronary angiography and angioplasty are standard procedures for managing coronary artery occlusion.
- Guiding catheters with side holes are used in interventional cardiology procedures.
Observation:
- A patient with acute inferior myocardial infarction underwent successful reperfusion with streptokinase and subsequent angioplasty.
- During post-angioplasty angiography, the balloon catheter could not be withdrawn into the guiding catheter.
- Fluoroscopy showed the balloon catheter had extruded through the side hole of the 8-French guiding catheter.
Findings:
- The extrusion of the balloon catheter through the guiding catheter side hole represents a rare but significant procedural complication.
- This event highlights potential risks associated with specific guiding catheter designs and balloon catheter interactions.
- The incident occurred despite the use of standard interventional cardiology equipment.
Implications:
- Awareness of this complication is crucial for interventional cardiologists to prevent or manage similar events.
- Further investigation into guiding catheter design and balloon catheter compatibility may be warranted.
- This case underscores the importance of meticulous technique and vigilance during complex interventional procedures.
Abstract:
A patient presented with an acute inferior myocardial infarction. Coronary angiography in the acute stage revealed total occlusion of the right coronary artery. Reperfusion was obtained after intracoronary infusion of 250,000 units of streptokinase. Angioplasty was subsequently performed because of a high grade residual stenosis. An 8-French right Judkins guiding catheter with a single side hole (USCI), a 3.0 mm balloon dilatation catheter (ACS), and a 0.018 high torque floppy guide wire (ACS) were used. After successful angioplasty angiography was repeated with the guide wire in the RCA, but the balloon was withdrawn into the guiding catheter. After injection of contrast, it was impossible to withdrawn the balloon catheter out of the guiding catheter. Fluoroscopy revealed extrusion of the balloon through the side hole in the guiding catheter.
