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.

Since then, there have been numerous articles proposing modified DKS procedures. Other surgical options include the Fontan Procedure see under Tricuspid Atresia and the Norwood Procedure see ksye Hypoplastic Left Heart Syndromewhich separate the pulmonary circulation to the lungs from the systemic circulation to the body.

Chan Kyu YangM. In echocardiography, there was no evidence of AR or neoAR. This situation may be treated by surgery. Korean J Thorac Cardiovasc Surg. Published online Aug 5. Typical approaches to the management of SVOTO include the enlargement of the bulboventricular foramen or the ventricular septal defect, and syansel resection of the subaortic conus.

The procedure was later accomplished via a “double-barrel” technique that resulted in a new aorta with two valves. Modified Damus-Kaye-Stansel procedure using aortic flap technique for systemic ventricular outflow tract obstruction in functionally univentricular heart.

It is possible to perform the double-barrel technique in kae 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. There was no early death and 1 late death in group B. 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.


There have been a few reports about which surgical technique shows better outcomes. The Damus—Kaye—Stansel DKS procedure is a cardiovascular surgical procedure used as part of the repair of some congenital heart defects.

We evaluated the preoperative echocardiographic results: 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 Management of univentricular heart with systemic ventricular outflow obstruction by pulmonary artery banding and Damus-Kaye-Stansel operation. Mid-term results for double inlet left ventricle and similar morphologies: Support Center Support Center.

Damus–Kaye–Stansel procedure – Wikipedia

How Is It Treated? No potential conflict of interest relevant to this article was reported. 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. In group A, 3 patients underwent the Gore-Tex or polytetrafluoroethylene graft interposition for preserving the shape of the pulmonary sinus, and 1 patient underwent aortopulmonary window creation.

Further, we followed-up with the postoperative echocardiographic results: They chose the DKS surgical technique according to the diameter of the ascending aorta. Experience with Damus procedure. The median age at the time of the DKS operation was 5.


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

However, the DKS procedure is technically difficult, and it is not easy to preserve the shape of the pulmonary sinus. This operation was first introduced for biventricular repair in patients with dextro-transposition of the great arteries [ 6 — 8 ].

Tricuspid atresia, transposition of the great arteries, and banded pulmonary artery: However, these procedures can cause heart block, ventricular dysfunction, and recurrent stenosis.

However, 7 months later, he was admitted via the emergency room owing to general weakness. We decided upon the DKS operation technique according to the relationship of the aorta and the main pulmonary artery. Six of the 12 patients underwent Fontan completion after the DKS operation, and 3 patients were waiting Fig. InMasuda et al.

Double-barrel Damus-Kaye-Stansel operation is better than end-to-side Damus-Kaye-Stansel operation for preserving the pulmonary valve function: Patient characteristics of the two groups. However, there have been few reports on which surgical technique shows a better outcome. B Ascending aorta flap technique group B. A Double barrel technique group A. Midterm results of surgical treatment of systemic ventricular outflow obstruction in Fontan patients.

The clinical application and results of palliative Damus-Kaye-Stansel procedure. For such cases, Fujii et al.
