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.

We divided the 12 patients into two groups according to the surgical technique used. The mean aortic cross-clamping time stanel By staansel late s, the procedure was employed in situations where the right ventricle is bigger than the left ventricle and the left ventricle connects to the pulmonary artery instead of the aorta ; examples include double inlet left ventricleTGA with tricuspid atresia and TGA with hypoplastic left heart syndrome.

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

We decided upon the surgical technique to use for the DKS procedure according to the relationship between the aorta and the main pulmonary artery. From Wikipedia, the free encyclopedia. No potential conflict of interest relevant to this article was reported. SVOTO could result in ventricular hypertrophy, impaired diastolic iaye, and subendocardial ischemia with subsequent deleterious effects on the single ventricle.

The objective of this study is to compare the outcomes of the DKS procedure according to the surgical technique used from the perspective of ddamus regurgitation and recurrent SVOTO, which are considered to be two major complications caused by the DKS procedure [ 12 — 14 ]. 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.


The median age at the time of the DKS operation was 5.

The results of long-term follow-up remain to be seen. Methods We retrospectively reviewed 12 consecutive patients who underwent the DKS procedure from March to April Congenital heart defects Cardiac surgery.

Only 1 patient had mild preoperative AR, and the rest had a degree of trivial. However, any functional single ventricle anomalies for example, tricuspid atresia and double inlet left ventricle with rudimentary bulboventricular foramen have the problem of systemic ventricular outflow tract obstruction SVOTO after volume reduction surgery. Korean J Thorac Cardiovasc Surg.

Retrieved from ” https: More than a moderate degree of postoperative AR was not seen in any of the 12 patients. This situation may be treated stanseo surgery.

Damus–Kaye–Stansel procedure

Some groups prefer the DKS procedure as an initial palliation for this reason. Since then, there have been numerous articles proposing modified DKS procedures. 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.

He underwent neo-aortic valve replacement 66 months after the DKS procedure. All DKS operations were performed by a single surgeon. Published online Aug 5. Group A underwent double barrel technique, and group B was performed ascending aorta flap technique.

There are few papers in the English literature comparing the results of the DKS operation according to the surgical technique used. Results There was no early mortality and 1 late mortality in group B. J Thorac Cardiovasc Surg.

Clinical outcomes of prophylactic Damus-Kaye- Stansel anastomosis concomitant with bidirectional Glenn procedure. Table 1 The preoperative cardiac diagnosis and operation performed in stages.

In this case, there was a possibility of the deformation of the shape stansrl the pulmonary sinus at the time of the DKS procedure.

We retrospectively reviewed 12 consecutive patients who underwent the DKS procedure from March to April There was no statistically significant difference in the median peak pressure gradient of preoperative subaortic stenosis in both groups: A Double barrel technique group A. National Center for Biotechnology InformationU. Please review our privacy policy.

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.

This page is available in: Views Read Edit View history. Our study shows that the DKS operation is a safe option for solving the problem of SVOTO and there are no significant differences in the clinical outcomes of the DKS operation according to the surgical technique used.

There were no statistically significant differences in the postoperative course, such as extubation, intensive care unit stay, or chest tube removal between group A and group B.

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