Blunt trauma can cause coronary artery dissection and aneurysm. Surgical repair and grafting successfully restored blood flow and improved heart function in a patient.

Area of Science:

Cardiology
Trauma Surgery
Vascular Surgery

Background:

Blunt deceleration trauma can lead to serious cardiovascular injuries, including coronary artery dissection.
Posttraumatic coronary aneurysms are rare but pose a risk of vessel occlusion and myocardial infarction.

Observation:

A 31-year-old male presented with blunt deceleration trauma resulting in left anterior descending coronary artery dissection.
A posttraumatic coronary aneurysm was identified, requiring surgical intervention to prevent future complications.

Findings:

Surgical repair of the coronary aneurysm was performed to maintain patency of the recanalized vessel.
An internal mammary artery graft was utilized prophylactically to mitigate the risk of postoperative thrombosis.
Twelve-month follow-up revealed significant improvement in left ventricular function.

Implications:

This case highlights the importance of recognizing and managing coronary artery injuries following blunt trauma.
Timely surgical repair and revascularization can prevent adverse cardiac events and improve long-term outcomes.
Internal mammary artery grafting serves as a viable option for preventing graft occlusion in complex coronary reconstructions.
