The Damus-Kaye-Stansel (DKS) procedure is a method for mitigating the risk of systemic ventricular outflow tract obstruction (SVOTO). However, there have. Damus-Kaye-Stansel Operation. This procedure usually complements other corrective procedures. It was originally developed along with the Rastelli procedure. Modified Damus-Kaye-Stansel procedure for single ventricle, subaortic stenosis, and arch obstruction in neonates and infants: Midterm results and techniques.

How Is It Treated?

Methods We retrospectively reviewed 12 consecutive patients who underwent the DKS procedure from March to April However, these studies did not compare the clinical outcomes of the other surgical techniques. More than moderate postoperative neoaortic regurgitation was observed in 1 patient of group B; this patient underwent neoaortic valve replacement 66 months after the DKS procedure.

Six of the 12 patients underwent Fontan completion after the DKS operation, and 3 patients were waiting Fig. Excessive pulmonary blood flow in double inlet left ventricle may be corrected by the insertion of a band around the trunk of the pulmonary artery shown in yellow on the diagram at right.

When the relationship of the great arteries was anterior-posterior, the double-barrel technique group A was performed. There are few papers in the English literature comparing the results of the DKS operation according to the surgical technique used.


Bwt, body weight; BSA, body surface area. This narrows the pulmonary artery, which stanwel blood flow. It is commonly used when a patient has the combination of a small left ventricle and a transposition of the great arteries TGA ; in this case, the procedure allows blood to flow from the left ventricle to the aorta.

InFujii et al. However, the DKS procedure is technically difficult, and it is not easy to preserve the shape of the pulmonary sinus.

The Clinical Outcomes of Damus-Kaye-Stansel Procedure According to Surgical Technique

Thereafter, a bovine pericardium was used for repairing the anterior defect Fig. Therefore, we performed PAB prior to the DKS operation to control the pulmonary blood flow and prevent the development of pulmonary vascular resistance [ 18 ]. The end of the MPA was then joined to the side of the ascending aortaallowing blood from the left heart to communicate directly with the aorta.

It is possible to perform the double-barrel technique in the case of a side-by-side relationship, and it is also possible to choose the ascending aorta flap technique in the case of the anterior-posterior relationship.

The Clinical Outcomes of Damus-Kaye-Stansel Procedure According to Surgical Technique

For such cases, Fujii et al. This situation may be treated by surgery. We decided upon the DKS operation technique according to the relationship of the aorta and the main pulmonary artery.


Clinical outcomes of prophylactic Damus-Kaye- Stansel anastomosis concomitant with bidirectional Glenn procedure. Table 3 The postoperative results in each group. By the late s, the procedure was employed in situations where the right ventricle is bigger than the left ventricle and the left ventricle kays to the pulmonary artery instead of the aorta ; examples include double inlet left ventricleTGA with tricuspid atresia and TGA with hypoplastic left heart syndrome.

This article is meaningful in that it compares the outcomes of two different surgical techniques, and to the best of our knowledge, in Korea, this is the first report to demonstrate the clinical outcomes of DKS according to the surgical technique used. This operation was first introduced for biventricular repair in patients with dextro-transposition of the great arteries [ 6 — 8 ]. However, 7 months later, he was admitted via the emergency room owing to general weakness.

Stansel — who independently reported the procedure in the literature in the s. The original DKS procedure was an end-to-side anastomosis between the main pulmonary artery and the ascending aorta.
