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 reviewed a small group of 12 samus, and the operation was performed by one surgeon in one institution. 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. A Double barrel technique group A.
This page is available in: Later, a modified DKS was reported in which an kayr flap technique was utilized. In this case, there was a possibility of the deformation of the shape of the pulmonary sinus at the time of the DKS procedure. 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.

Damus–Kaye–Stansel procedure – Wikipedia
Damus—Kaye—Stansel procedure [ edit on Wikidata ]. We evaluated the preoperative echocardiographic results: However, our study has certain limitations. Low pulmonary vascular resistance improves the outcome of the Fontan operation.
Group A underwent double barrel technique, and group B was performed ascending aorta flap technique. The clinical application and results of palliative Damus-Kaye-Stansel procedure.
The Clinical Outcomes of Damus-Kaye-Stansel Procedure According to Surgical Technique
Therefore, we performed PAB prior to the DKS operation to control the pulmonary blood flow and prevent the development of pulmonary vascular resistance [ 18 ].
Chan Kyu YangM. No potential conflict of interest relevant to this article was reported.
Korean Journal of Thoracic and Cardiovascular Surgery. The median peak pressure gradient of subaortic stenosis was 15 mmHg range, 0 to 53 mmHg. Six of the 12 patients underwent Fontan completion after the DKS operation, and 3 patients were waiting Fig.
Double-barrel Damus-Kaye-Stansel operation is better than end-to-side Damus-Kaye-Stansel operation for preserving the pulmonary valve function: We decided upon the DKS operation technique according to the relationship of the aorta and the main pulmonary artery. Results There was no early mortality and 1 late mortality in group B.
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, functional single ventricle anomalies are usually associated with excessive pulmonary blood flow. Retrieved November 16, There have been a few reports about which surgical technique shows better outcomes.
There was no statistically significant difference in the median peak pressure gradient of preoperative subaortic stenosis in both groups: Korean J Thorac Cardiovasc Surg. Eur J Cardiothorac Surg. However, 7 months later, he was admitted via the emergency room owing to general weakness.
When the relationship of the great arteries was anterior-posterior, the double-barrel technique group A was performed. Patients with a functional single ventricle undergo multiple-stage operations, including postnatal palliations, which restrict or increase pulmonary blood flow according to the amount of the existing pulmonary blood flow, bidirectional cavopulmonary shunt, and finally, the Fontan operation.
We divided the 12 patients into maye groups according to the surgical technique used. Sransel was no early death and 1 late death in group B. J Thorac Cardiovasc Surg. This situation may be treated by surgery. Views Read Edit View history.
How Is It Treated? Modified Damus-Kaye-Stansel procedure using aortic flap technique for systemic ventricular outflow tract obstruction in functionally univentricular heart. If the great arteries had the relationship of anterior-posterior, we chose the double-barrel technique group Aand if they lay side-by-side, we performed the ascending aorta flap technique group Bwhich is a type of end-to-side DKS procedure with patch augmentation [ 12 ].
They chose the DKS surgical technique according to the diameter of the ascending aorta. 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. National Center for Biotechnology InformationU.
Since then, there kaaye been numerous articles proposing modified DKS procedures. He underwent neo-aortic valve replacement 66 months after the DKS procedure. From Wikipedia, the free encyclopedia.
Damus-Kaye-Stansel Procedure 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. The mean aortic cross-clamping time was Further, 1 patient had mild preoperative PR, and the rest had a degree of trivial. The procedure was later accomplished via a “double-barrel” technique that resulted in a new aorta with two valves.
Pulmonary artery banding before the Damus-Kaye-Stansel procedure. Moreover, DKS stqnsel an initial palliation in neonates is not technically easy. For such cases, Fujii et al. Stansel — who independently reported the procedure in the literature in the s.
