[Acute diffuse thrombosis of left coronary artery complicating coronary angioplasty]

Area of Science:

• Cardiology
• Interventional Cardiology
• Thrombosis Research

Background:

• Acute coronary syndrome (ACS) management involves interventions like coronary angioplasty.
• Complications such as thrombosis can occur post-angioplasty, necessitating advanced treatment strategies.
• Heparin resistance presents a significant challenge in managing thrombotic events during cardiac procedures.

Observation:

• A 39-year-old patient developed acute diffuse thrombosis in the left coronary artery after coronary angioplasty.
• The thrombosis extended throughout the anterior descending artery and involved the circumflex artery ostium.
• The patient exhibited heparin resistance, complicating the initial management.

Findings:

• A multi-faceted therapeutic approach was employed, including repeated heparin administration and intracoronary streptokinase.
• Mechanical thrombus destruction via stenting of the circumflex artery ostium was performed.
• These interventions successfully restored adequate coronary blood flow.

Implications:

• This case demonstrates a successful strategy for managing complex post-angioplasty thrombosis, even with heparin resistance.
• The combination of pharmacologic and mechanical interventions can be effective in critical thrombotic scenarios.
• Findings contribute to understanding treatment options for rare but severe coronary artery thrombosis complications.
