[Coronary dissection following coronary radiography].

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology
• Radiology

Background:

• Coronary radiography is a diagnostic imaging technique used to visualize the coronary arteries.
• Dissection of coronary arteries is a rare but potentially life-threatening complication.
• Prompt diagnosis and intervention are crucial for favorable patient outcomes.

Observation:

• Four cases of spontaneous coronary artery dissection (SCAD) occurred during coronary radiography.
• Two cases involved the right coronary artery, and two involved the left coronary artery.
• All patients required emergency surgical intervention.

Findings:

• Coronary artery bypass grafting (CABG) using saphenous vein grafts was performed in all four patients.
• One patient experienced myocardial infarction post-operatively.
• All patients demonstrated successful recovery and long-term evolution.

Implications:

• Coronary radiography, while diagnostic, carries a risk of iatrogenic coronary artery dissection.
• Emergency surgical revascularization with saphenous vein grafts is an effective treatment for this complication.
• Increased vigilance and preparedness for managing coronary artery dissection during radiography are warranted.
