Thrombus formation in the ascending aorta: a complication of angioplasty
Insights
Percutaneous transluminal coronary angioplasty (PTCA) can cause aortic thrombus, a rare complication. Careful monitoring during prolonged procedures, especially for left anterior descending artery lesions, is crucial to prevent this risk.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Medical Complications
Background:
- Percutaneous transluminal coronary angioplasty (PTCA) effectively treats coronary stenosis.
- PTCA carries a risk of thromboembolic events.
- Aortic thrombus formation is a previously unreported complication of PTCA.
Observation:
- Two patients developed thrombus in the ascending aorta during PTCA.
- The procedures involved angioplasty of the left anterior descending artery (LAD).
- The lateral view during dilatation for LAD lesions was noted.
Findings:
- A novel complication of PTCA involving ascending aortic thrombus was observed.
- The occurrence was specifically noted during LAD interventions.
- Prolonged procedures and specific imaging views may be contributing factors.
Implications:
- Highlights a rare but serious complication of PTCA.
- Suggests increased vigilance during LAD angioplasty, particularly prolonged procedures.
- Emphasizes the importance of imaging views, like the lateral view, in detecting and potentially preventing this complication.
Abstract:
Percutaneous transluminal coronary angioplasty (PTCA) is recognized as an effective therapeutic procedure for nonsurgical relief of critical coronary stenosis. However, this procedure has the inherent traumatic risk of thromboembolic phenomenon in treated patients. This paper describes a hiterto unreported complication. In two patients a thrombus appeared in the ascending aorta during PTCA performed in the left anterior descending artery (LAD). Mechanisms involved are postulated. It is emphasized that particular attention should be paid to the lateral view in dilatation to treat LAD lesion, especially if the procedure is prolonged.
