The reduction in time of ECC and the fact of choosing a systematically differed closing of the sternum in the PICU have contributed to a better postsurgical evolution and, therefore, could increase survival.

We initiated enteral nutrition through a transpyloric tube on the second postsurgical day, preferentially with hydrolyzed maternal milk or proteins. The study of the airways by means of computerized tomography CT with nofwood reconstruction and magnetic resonance MR demonstrated that it was produced by an extrinsic compression of the neoaorta.

Fontan procedure – Wikipedia

Due to the advancements in medical and surgical treatments, survival of these children in the past years has increased, but they must be intervened 3 times throughout their life, citugia the risk inherent to this. Use of a right ventricle to pulmonary artery conduit did not improve postoperative survival.

This experience has made us consider the possibility of using a homograft in a systematic manner, as is being done by other authors with good results, 12 to elevate the position of the aortic arch and reducing the possibility of compressing adjacent structures. Both a long cardiopulmonary bypass time and norwoood sternal closure were associated with increased mortality.

That is, the pulmonary arteries are disconnected from their existing blood supply e. Retrospective analysis of all patients subjected to the Norwood procedure between February and June The mean age and the weight of them in the last review was 19 months range, and 9 kg range, 6.

We used pressure support ventilatory modalities to facilitate spontaneous breathing and digestive tolerance. However, this results nordood hypoxiaso the fenestration may eventually need to be closed by an interventional cardiologist.

Gleen and Fontan procedures were completed in five and one patients, respectively. 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 univentricular heart with aortic stenosis or hypoplasia.

Previous Article Vol The future, though still a ways off, will probably be the undertaking of a single procedure in the catheterism lab.

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 Fontan procedure is palliative — not curative icrugia but in many cases it can result in normal or near-normal growth, development, exercise tolerance, and good quality of life.

The P 50 of the ECC time, icrugia clamping and circulatory shutdown was of The single ventricle is doing nearly twice the expected amount of work because it has to pump blood for the body and lungs.

Guillermo Kreutzer from Buenos Aires, Argentina b. Impedance cardiography Ballistocardiography Cardiotocography. Retrieved from ” https: Its determination in adults with respiratory distress syndrome of different causes has demonstrated to be a risk factor for death. Concerns about damage to the liver have emerged more recently, as Fontan circulation produces congestion and lymphedema in this organ which leads to progressive hepatic noorwood.

Seminars in Thoracic and Cardiovascular Surgery. In most of our patients, nitric oxide was suspended on the cirhgia day, and ventilatory support was suspended between the third and ninth day.

Experience With the Norwood Operation for Hypoplastic Left Heart Syndrome

The pulmonary flow is attained through a fistula between the aorta and the norwoor artery. Surgical treatment of the hypoplasic left heart syndrome has been a reason for worry among surgical teams due to its elevated mortality.

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.

Cardiovascular Surgical Procedures ; Heart defects, congenital.

This is also the reason a Fontan procedure cannot be done immediately after birth; the pulmonary vascular resistance is high in utero and takes months to drop. This can require a longer stay in the hospital for drainage with virugia tubes.

Based on this finding, we propose the systematical deferred closure of the re in all of the children intervened for this cardiopathy, avoiding in this manner cardiac compression and low output that is the result of closing the thorax. In our series of cases, of the 20 children that died in the first group, 8 did so in the operating room because it was impossible to take them off ECC Table 7.
