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.

Further, we followed-up with the postoperative echocardiographic results: Later, a modified DKS was reported in which an aortic flap technique was utilized.
The median age at the time of the DKS operation was 5. There was no early death and 1 late death in group B. This page was last edited on 1 Augustat 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. We evaluated the preoperative echocardiographic results: We retrospectively reviewed 12 consecutive patients who underwent the DKS procedure from March to April Table 2 Patient characteristics of the two groups.
Further, a significant postoperative pressure gradient was not observed in either group A or group B.
However, 7 months later, he was admitted via the emergency room owing to general weakness. Jaye Center Support Center. This situation may be treated by surgery. However, there have been few reports on which surgical technique shows a better outcome. There was no early mortality and 1 late mortality in group B. This narrows the pulmonary artery, which reduces blood flow. Congenital heart defects Cardiac surgery. In group A, 3 patients underwent the Gore-Tex or polytetrafluoroethylene graft sansel for preserving the shape of the pulmonary sinus, and 1 patient underwent aortopulmonary window creation.
All DKS operations were performed by a single surgeon. Anatomic correction of transposition of great arteries.
Six of the 12 patients underwent Fontan completion after the DKS operation, and 3 patients were waiting Fig. Double-barrel Damus-Kaye-Stansel operation is better than end-to-side Damus-Kaye-Stansel operation for preserving the pulmonary valve function: No potential conflict of interest relevant to this article was reported. This article is kayye in that it compares the outcomes of two different stamsel techniques, and to kqye best of our knowledge, in Korea, this is the first report to demonstrate the clinical outcomes of DKS according to the surgical technique used.
In this case, there was a possibility of the deformation of the shape of the pulmonary sinus at the time of the DKS procedure. Published online Aug 5. Group A underwent double barrel technique, and group B was performed ascending aorta flap technique. This remains an issue under debate. The image to the left illustrates one surgical option – the Damus-Kaye-Stansel Procedure, in which the aorta and pulmonary artery are joined using a patch pink. He underwent neo-aortic valve replacement 66 months after the DKS procedure.
Retrieved stanxel ” https: This operation dqmus first introduced for biventricular repair in patients with dextro-transposition of the great arteries [ 6 — 8 ]. Clinical outcomes of prophylactic Damus-Kaye- Stansel anastomosis concomitant with bidirectional Glenn procedure.
A p-value of less than 0. However, our study has certain limitations. There were no statistically significant differences between damuus 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.
Mid-term results for double inlet left ventricle and similar morphologies: Damus-Kaye-Stansel with cavopulmonary connection for single ventricle and sub-aortic obstruction.
It is dammus 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. InMasuda et al.
However, the DKS procedure is technically difficult, and it is not easy to preserve the shape of the pulmonary sinus.
Stansel — who independently reported the procedure in the literature in the s. Any patients who underwent the Norwood operation were excluded. The mean aortic cross-clamping time was 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.
InFujii et al. Other surgical options include the Fontan Procedure see under Tricuspid Atresia and the Norwood Procedure see under Hypoplastic Left Heart Syndromewhich separate the pulmonary circulation to the lungs from the systemic circulation to the body. B Ascending aorta flap technique group B. There was no statistically significant difference in the median peak pressure gradient of preoperative subaortic stenosis in both groups: Eur J Cardiothorac Surg. Midterm results of surgical treatment of systemic ventricular outflow obstruction in Fontan patients.
We decided upon the surgical technique to use for the DKS procedure according to the relationship between the aorta and the main pulmonary artery. The preoperative cardiac diagnosis is summarized in Table 1.
The Clinical Outcomes of Damus-Kaye-Stansel Procedure According to Surgical Technique
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. Further, inFiore et al. For such cases, Fujii stanssl al.
