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.

A p-value of less than 0.

The preoperative cardiac diagnosis is summarized in Table 1. Further, they suggested that an almost equal diameter of the ascending aorta to that of the pulmonary trunk was a good indication for the double-barrel technique.

Damus—Kaye—Stansel procedure [ edit on Wikidata ]. National Center for Biotechnology InformationU. The other associated procedures were atrial septectomy in 7 patients, stanseel angioplasty with bovine pericardium in 3 patients, and neoaortopexy in 1 patient.

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. From Wikipedia, the free encyclopedia. We evaluated dams preoperative echocardiographic results: He underwent neo-aortic valve replacement 66 months after the DKS procedure.

No potential conflict of interest relevant to this article was reported. Mid-term results for double inlet left ventricle and similar morphologies: Please review our privacy policy. Standel could result in ventricular hypertrophy, impaired diastolic function, and subendocardial ischemia with subsequent deleterious effects on the single ventricle. For such cases, Fujii et al. Todd; Bisset, George June 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.


The median age at the time of the DKS operation was 5. 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. Some groups prefer the DKS procedure as an initial palliation for this reason.

There was no early death and 1 late death in group B. Recurrent systemic ventricular outflow tract obstruction.

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

Further, we followed-up with the postoperative echocardiographic results: Seven of the 12 patients underwent the double-barrel technique group Aand 5 patients underwent the ascending aorta flap technique group B. Six of the 12 patients underwent Fontan completion after the DKS operation, and 3 patients were waiting Fig.

There may be complications after the Pulmonary Band Procedure, resulting in obstructions to the flow of blood through the aorta to the body. Table 2 Patient characteristics of the two groups. Patient characteristics of the two groups. The median peak pressure gradient of subaortic stenosis was 15 mmHg range, 0 to 53 mmHg. Eur J Cardiothorac Surg. Management of univentricular heart with systemic ventricular outflow obstruction by pulmonary artery banding and Damus-Kaye-Stansel operation.

However, there have been few reports on which surgical technique shows a better outcome.

Damus–Kaye–Stansel procedure

However, 7 months later, he was admitted via the emergency room owing to general weakness. Author information Article notes Copyright and License information Disclaimer.


The results of long-term follow-up remain to be seen. However, the DKS procedure is technically difficult, and it is not easy to preserve the shape of the pulmonary sinus.

Pulmonary artery banding before the Damus-Kaye-Stansel procedure. Outcomes of Damus-Kaye-Stansel anastomosis at time of cavopulmonary connection in single ventricle patients at risk of developing systemic ventricular outflow tract obstruction.

There was no statistically significant difference in the median peak pressure gradient of preoperative subaortic stenosis in both groups: Low pulmonary vascular resistance improves the outcome of the Fontan operation. Any patients who underwent the Norwood operation were excluded. There are few papers in the English literature comparing the results of the DKS operation according to the surgical technique used.

If the kaje arteries had the relationship of anterior-posterior, we chose the double-barrel technique group A sstansel, and 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 ]. The objective of this study was to compare the outcome of the DKS procedure according to the surgical technique used.

Since then, there have been numerous articles proposing modified DKS procedures.

Anatomic correction of transposition of great arteries. This remains an issue under debate.
