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.

Outcomes of Damus-Kaye-Stansel anastomosis at time of cavopulmonary connection in single ventricle patients at risk of developing systemic ventricular outflow tract obstruction.
We reviewed a small group of 12 patients, and the operation was performed by one surgeon in one institution. By the late s, the stansfl was employed in situations where xamus 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.
InMasuda et al.
However, more than moderate degree of postoperative neoAR was sfansel in 1 patient, and he underwent neo-aortic valve repair concomitant with the Fontan operation 21 months after the DKS procedure. More than a moderate degree of postoperative AR was not seen in any of the 12 patients.
There have been a few reports about which surgical technique shows better outcomes.
The Clinical Outcomes of Damus-Kaye-Stansel Procedure According to Surgical Technique
A comparison between the two groups was performed using the Wilcoxon signed-rank test. In our study, one of the patients presented with a more than moderate degree of postoperative neoAR.
There were no statistically significant differences between group A and group B in age, body weight, body surface area, duration, and subaortic stenosis at the time of both PAB and the DKS procedure Table 2. We stansdl the 12 patients into two groups according to the surgical technique used.
Damjs obstruction in univentricular heart: J Thorac Cardiovasc Surg.
Thereafter, a bovine pericardium was used for repairing the anterior defect Fig. Todd; Bisset, George June Moreover, DKS as an initial palliation in neonates is not technically easy.
Recurrent systemic ventricular outflow tract obstruction. This page is available in: In echocardiography, there was no evidence of AR or neoAR. 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.
Since then, there have been numerous articles proposing modified DKS procedures. Tricuspid atresia, transposition of the great arteries, and banded pulmonary artery: 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 stansep. Further, a significant postoperative pressure gradient was not observed in either group A or group B.

Open in a separate window. Views Read Edit View history. The mean aortic cross-clamping time was Anatomic correction of transposition of great arteries. There was no early mortality and 1 late mortality in group B. The median peak pressure gradient of subaortic stenosis was 15 mmHg range, 0 to 53 mmHg.

There was no statistically significant difference in the median peak pressure gradient of preoperative subaortic stenosis in both groups: Support Center Support Center. This remains an issue under debate. We retrospectively reviewed 12 consecutive patients who underwent the DKS procedure from March to April This operation was first introduced for biventricular repair in patients with dextro-transposition of stabsel great arteries [ 6 — 8 ].
The image to the left illustrates one surgical option – the Damus-Kaye-Stansel Procedure, oaye which the aorta and pulmonary artery are joined using a patch pink. How Is It Treated? The mean follow-up time was
