Damus–Kaye–Stansel procedure

The Damus–Kaye–Stansel procedure (DKS) is a surgical technique employed in the treatment of congenital heart defects. This procedure plays a pivotal role in redirecting blood flow and improving circulation, particularly in pediatric cardiac surgery.

Overview

The Damus–Kaye–Stansel procedure is named after the three pioneering surgeons who independently described and refined it: Dr. Albert Damus, Dr. William Kaye, and Dr. Richard Stansel. It is primarily used in cases of congenital heart defects where the normal circulation of oxygen-rich and oxygen-poor blood between the heart and the lungs is disrupted.

Surgical Technique

The primary objective of the Damus–Kaye–Stansel procedure is to create a controlled connection between the pulmonary artery and the aorta, allowing for mixing of oxygen-rich and oxygen-poor blood. This mixing is essential because certain congenital heart defects result in an inadequate supply of oxygen to the body.

The typical steps involved in the DKS procedure include identifying a suitable location for creating the connection, making incisions in the aorta and the pulmonary artery, creating an anastomosis (connection) between these two vessels, and closely monitoring blood flow to ensure proper mixing of oxygenated and deoxygenated blood.

Indications

The Damus–Kaye–Stansel procedure is usually indicated in scenarios such as:

• Single ventricle physiology as part of a staged surgical approach.
• Transposition of the great arteries (TGA) or other complex congenital heart diseases that require redirection of blood flow.
• As a palliative measure to enhance oxygenation and circulation while awaiting further corrective surgeries.

Conclusion

The Damus–Kaye–Stansel procedure is a valuable surgical technique in the field of congenital heart surgery. It addresses complex cardiac anomalies by redirecting blood flow and improving oxygenation, often as part of a staged treatment plan. This procedure has significantly improved outcomes and quality of life for many patients with congenital heart defects, particularly in pediatric cases.

As with any medical procedure, the decision to perform the DKS procedure is made on a case-by-case basis, considering the individual patient's condition and overall treatment plan. Advances in cardiac surgery continue to refine and enhance this technique, offering hope to those affected by congenital heart diseases.
