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.

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

This situation may be treated by surgery. Damus-Kaye-Stansel with cavopulmonary connection for single ventricle and sub-aortic obstruction. Therefore, we performed PAB prior to the DKS operation to control the pulmonary blood flow and prevent the development of pulmonary vascular resistance [ 18 ].

Korean J Thorac Cardiovasc Surg. This page kayw available in: Retrieved November 16, Some groups prefer the DKS procedure as an initial palliation for this reason. Support Center Support Center. In the original DKS procedure, surgeons separated the main pulmonary artery Dqmus just below the point where it divides into the right and left pulmonary arteries. Modified Damus-Kaye-Stansel procedure sgansel aortic flap technique for systemic ventricular outflow tract obstruction in functionally univentricular heart.

Seven of the 12 patients underwent the double-barrel technique group Aand damuw patients underwent the ascending aorta flap technique 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. Low pulmonary vascular resistance improves the outcome of the Fontan operation. Further, inFiore et al. Recurrent systemic ventricular outflow tract obstruction.


The objective of this study was to compare the outcome of the DKS procedure according to the surgical technique used. Moreover, DKS as an initial palliation in neonates is not technically easy.

Further, a significant postoperative pressure gradient was not observed in either group A or group B. Published online Aug 5. In this case, there was a possibility of the deformation of the shape of the pulmonary sinus at the da,us of the DKS procedure. The median peak pressure gradient of subaortic stenosis was 15 mmHg range, 0 to 53 mmHg. The original DKS procedure was an end-to-side anastomosis between the main pulmonary artery and the ascending aorta.

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 daus, the procedure allows blood to flow from the left ventricle to the aorta. 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.

Todd; Bisset, George June However, more than moderate degree of postoperative neoAR was observed in 1 patient, and he underwent neo-aortic valve repair concomitant with the Fontan operation 21 months after the DKS procedure. However, these studies did not compare the clinical outcomes of the other surgical techniques. However, our study has certain limitations.

Table 1 The preoperative cardiac diagnosis and operation performed in stages. Bwt, body weight; BSA, body surface area. The preoperative cardiac diagnosis is summarized in Table 1. Experience with Stasnel procedure.

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 damsu aorta flap technique group Bwhich is a type of end-to-side DKS procedure with patch augmentation [ 12 ].

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

There was no statistically significant difference in the median peak pressure gradient of preoperative subaortic stenosis in both groups: 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.

There were no statistically significant ramus 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.
