Intracoronary thrombolytic treatment: another hazard
Insights
Intracoronary thrombolysis for myocardial infarction risks thrombus detachment. Angiography and thrombolytic therapy require careful consideration of this potential complication.
Area of Science:
- Cardiology
- Interventional Cardiology
Background:
- Acute anterior myocardial infarction requires prompt reperfusion therapy.
- Intracoronary thrombolysis is a treatment option for acute myocardial infarction.
Observation:
- During cardiac catheterization for acute anterior myocardial infarction, contrast injection dislodged an occluding thrombus.
- The dislodged thrombus embolized to the circumflex artery.
Findings:
- The embolized thrombus fortunately fragmented, avoiding complete occlusion of the circumflex artery.
- Thrombus dislodgement is a potential risk during intracoronary thrombolysis.
Implications:
- Clinicians must consider the risk of thrombus embolization when performing angiography and thrombolytic therapy in acute myocardial infarction.
- Careful technique during interventions may mitigate the risk of distal embolization.
Abstract:
A patient with acute anterior myocardial infarction was treated with intracoronary thrombolysis. At cardiac catheterisation the first contrast injection into the left coronary artery dislodged some of the thrombus occluding the left anterior descending coronary artery. The thrombus embolised into the circumflex artery where fortunately it fragmented without causing occlusion. The risk of detachment of thrombus should be borne in mind when angiography and thrombolytic treatment are considered in acute myocardial infarction.
