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.

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 kaey.

Seven of the 12 patients underwent the double-barrel technique group Aand 5 patients underwent the ascending aorta flap technique group Samus. However, our study has certain limitations. 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 kqye, in Korea, this is the first report to demonstrate the clinical outcomes of DKS according to the surgical technique used.

Damus–Kaye–Stansel procedure

The Damus—Kaye—Stansel DKS procedure is a cardiovascular surgical procedure used as part of the repair of some congenital heart defects. There may be complications after the Pulmonary Band Procedure, resulting in obstructions to the flow of blood through the aorta to the body. The other associated procedures were atrial septectomy in 7 patients, pulmonary angioplasty with bovine pericardium in 3 patients, and neoaortopexy in 1 patient.

However, the DKS procedure is technically difficult, and it is not easy to preserve the shape of the pulmonary sinus. Since then, there have been numerous articles proposing modified DKS procedures.

Typical approaches to damuus management of SVOTO include the enlargement of the bulboventricular foramen or the ventricular septal defect, and the resection of the subaortic conus.


How Is It Treated? This patient underwent PAB, coarctoplasty, and infracardiac obstructive total anomalous pulmonary venous connection repair before the DKS procedure.

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

The results of long-term follow-up remain to be seen. Later, ztansel modified DKS was reported in which an aortic flap technique was utilized. Anatomic correction of transposition of great arteries.

Illustration of surgical technique. We retrospectively reviewed 12 consecutive patients who underwent the Stasnel procedure from March to April Patient characteristics of the two groups.

The median peak pressure gradient of subaortic stenosis was 15 mmHg range, 0 to 53 mmHg. The preoperative cardiac diagnosis is summarized in Table 1.

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

By the late s, the procedure was employed in situations where the 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. 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.

This operation was first introduced for biventricular repair in patients with dextro-transposition of the great arteries [ 6 — 8 ]. In echocardiography, there was no evidence of AR or neoAR. B Ascending aorta flap technique group B. 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.

From Wikipedia, the free encyclopedia. Retrieved from ” https: 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.

We decided upon the DKS operation technique according to the relationship of the aorta and the main pulmonary artery. Pulmonary artery banding before the Damus-Kaye-Stansel procedure. This situation dajus be treated by surgery. By using this site, you agree to the Terms of Use and Privacy Policy. 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.


Experience with Damus procedure. Further, we followed-up with the postoperative echocardiographic results: Further, 1 patient had mild stznsel PR, and the rest had a degree of trivial. There was no statistically significant difference in the median peak pressure gradient of preoperative subaortic stenosis in both groups: Eur J Cardiothorac Surg.

Double Inlet Left Ventricle. 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 ]. Views Read Edit View history. However, these procedures can cause heart block, ventricular dysfunction, and recurrent stenosis. Published online Aug 5.

Midterm results of surgical treatment of systemic ventricular outflow obstruction in Fontan patients. InMasuda et al.

Please review our privacy policy. This narrows the pulmonary artery, which reduces blood flow. Outcomes of Damus-Kaye-Stansel anastomosis at time of cavopulmonary connection in single ventricle patients at risk of developing systemic ventricular outflow tract obstruction.

Shansel, we performed PAB prior to the DKS operation to control the pulmonary blood flow and prevent the development of pulmonary vascular resistance [ 18 ].
