The Fontan procedure or Fontan–Kreutzer procedure is a palliative surgical procedure used in from their existing blood supply (e.g. a shunt created during a Norwood procedure, a patent ductus arteriosus, etc.). Leval, Marc R de ( ). d Servicio de Cirugía Cardiovascular, Hospital Infantil Universitario Virgen del Between October and June , 42 children underwent the Norwood.

The first stage, also called a Bidirectional Glenn procedure or Hemi-Fontan see also Kawashima procedureinvolves redirecting oxygen-poor blood from the top of the body to the lungs. Norwood procedure is used as the first stage in the palliative treatment of the hypoplastic heart syndrome and can be used, with some technical modifications, in other forms of norwoood heart with aortic stenosis or hypoplasia.
It attempts to make the right ventricle act like a systemic ventricle, connecting the trunk of the pulmonary artery to the aorta. We have not demonstrated an increase in survival of children in the PICU who d surgery using the Sano-modified of the classic Norwood technique. The second stage, also called Fontan completioninvolves redirecting the blood from the IVC to the lungs.

Hospital mortality, constituted by intrasurgical and postsurgical mortality was analyzed before discharge. Therefore, children with high pulmonary vascular resistance may not tolerate a Fontan procedure. In relation to the surgical times, only the time of ECC was associated significantly cirugla mortality, so that it was greater in those that died in the ciruvia room Table 6 and in PICU Table 3.
The age and the weight of the children at the moment of the intervention did not have a significant statistical relationship with mortality Table 3. The surgical technique used in them to reconstruct the aortic arc was the terminoterminal suture without aortic graft.
Please help improve this article by adding citations to reliable sources. All technical variations, according to the disposition and anatomy of the great vessels, are described. Three patients died in the perioperative period and three died in the follow up two, four and 10 months after the procedure.
The association between the quantitative variables was done using the Spearman rank coefficient.
The fraction of the pulmonary dead space is considered normal if between 0. Tissue oxygen extraction EtO 2 measures the oxygen consumption by waves, so that when tissue perfusion is jeopardized, it slows blood flow and increases its extraction, lowering the S v O 2 and increasing the venous PCO 2.
In a similar manner to other authors, 12 we have also proven that time on ECC is a risk factor for early mortality in the PICU, in the sense that the longer the time on ECC, the most likely the patient will die.
The future, though still a ways off, will probably be the undertaking of a single procedure in the catheterism lab. In the short term, children can dr trouble with pleural effusions fluid building up around the lungs.
Fontan procedure is also contraindicated in those with pulmonary artery hypoplasia, patients with left ventricular dysfunction and significant mitral insufficiency. Between October and June42 children underwent the Norwood procedure. Pericardium Pericardiocentesis Pericardial window Pericardiectomy Myocardium Cardiomyoplasty Dor ds Septal myectomy Ventricular reduction Alcohol septal ablation Conduction system Maze procedure Cox maze and minimaze Catheter ablation Cryoablation Radiofrequency ablation Pacemaker insertion Left atrial appendage occlusion Cardiotomy Heart transplantation.
Its measurement evaluates in an indirect form the pulmonary flow and allows identifying children with a jeopardized pulmonary flow. This way we minimized the fluctuations in the systemic and pulmonary resistance and maintained a stable circulatory and respiratory state.
Journal of the American College of Cardiology.
Some of the quantitative variables did not follow a normal distribution test of Noraoodreason for which they were described as a mean interquartile range. The first 30 patients group 1 underwent the classic 1 Norwood technique, receiving a modified Blalock-Taussig fistula of different diameters, and in the other 12 group 2 the Sano 4 variant was used.
A P value less than.
Among the anatomical characteristics of the cardiopathy we emphasized that the average diameter of the ascending aorta was 3. The PICU treatment initiated in the operating room was continued, with the objective to optimize cardiac output and to reduce to the systemic and pulmonary vascular resistance to the maximum.
Progress in Pediatric Cardiology. The inferior vena cava IVCwhich carries blood returning from the lower body, continues to connect to the heart. It was initially described in by Dr.
However, this results in hypoxiaso the fenestration may eventually need to be closed by an interventional cardiologist.

Their determination has the advantage that it can be carried out easily with the common monitorization of PICU. Both patients died due to respiratory insufficiency before a tensile stent could be implanted in the bronchial light. The hypoplasic left heart syndrome is a serious congenital cardiopathy that leads to surgery in the first days of life.
We made an immediate postsurgical heart ultrasound to evaluate ventricular function, the size of the auricular defect, the competence of the tricuspid valve, criugia the flow through the fistula, or the ventriculopulmonary tube. As far as the postsurgical monitorization in the PICU, there were no significant differences between the groups of survivors and deceased in the following variables: The cieugia of these variables is undergoing with the objective of carrying out a new analysis when the size of the sample is higher.
Use of a right ventricle to pulmonary artery conduit did not improve postoperative survival. Abstract Introduction and objectives. We initiated enteral nutrition through a transpyloric tube on the second postsurgical day, preferentially with hydrolyzed maternal milk or proteins.
Patients typically present as neonates with cyanosis or congestive heart failure. Nature Clinical Practice Cardiovascular Medicine.
We did not find significant differences either between mortality in PICU and the surgical technique used. February Learn how and when to remove this template message. The mean age and the weight of them in the last review was 19 months range, and 9 kg range, 6.
In the analytical control we measured arterial and venous blood gases, oxygen saturation SO 2 by noninvasive, and continuous pulse-oxymetry and the carbon dioxide CO 2 through capnography.
Fontan procedure – Wikipedia
The Fontan procedure is used in pediatric patients who possess only a single functional ventricle, either due to lack of a heart valve e. Retrospective analysis of all patients subjected to the Norwood procedure between February and June Gleen and Fontan procedures were completed in five and one patients, respectively.
