Subclavian artery dissection during diagnostic cardiac catheterization: the role of conservative management

Area of Science:

• Cardiology
• Vascular Surgery
• Interventional Cardiology

Background:

• Cardiac catheterization is a common procedure.
• Complications, though rare, can occur.
• Left internal mammary artery cannulation presents unique challenges.

Observation:

• A patient undergoing cardiac catheterization developed a dissection of the left subclavian artery during left internal mammary artery cannulation.
• This specific complication, subclavian artery dissection during LIMA cannulation, has not been previously reported in medical literature.

Findings:

• Conservative management, including close monitoring and medical treatment, was initiated for the subclavian artery dissection.
• The conservative approach led to a successful resolution of the vascular injury without surgical intervention.

Implications:

• Conservative management is a viable and effective alternative to high-risk surgery for subclavian artery dissection post-cardiac catheterization.
• This case highlights the importance of considering non-operative strategies for managing rare vascular injuries.
• Further research may explore the long-term outcomes and optimal conservative protocols for such injuries.
