BIDIRECTIONAL CAVOPULMONARY SHUNT PDF

bidirectional cavopulmonary shunt because of increasing cyanosis and growth cessation. All patients were consid- ered less than “ideal” candidates for a Fontan . The bidirectional cavopulmonary shunt, like the classic. Glenn anastomosis, by virtue of increasing the effective pulmonary flow improves the systemic arterial. Abstract. Objectives: The bidirectional cavopulmonary (Glenn) shunt is a commonly performed procedure for a variety of cyanotic congenital.

Deoxygenated blood from the inferior vena cava cavopulminary with oxygen-rich blood from the pulmonary veins in the common atrium out to the right ventricle and through the neoaorta. We observed that during the same clamp period there was a gradual decrease in the central venous pressure without much difference in the systemic arterial pressure. I do not know if there are other questions.

This study was conducted to highlight our surgical experience with this procedure in a developing country. Postoperative course and early results.

Echocardiographic evaluation before bidirectional Glenn operation in functional single-ventricle heart disease: Reproduced from Baba et al, 23 with permission from Wolters Kluwer.

Understanding Stage II Bidirectional Cavopulmonary Shunts

In all our patients, though we did not use any conventional decompressive technique, we attempted to clamp the SVC below the insertion of azygous vein whenever possible. Previous placement of pulmonary artery bands may cause the proximal pulmonary arteries to become narrowed and tortuous, necessitating reconstruction of the branch pulmonary artery during the BCPS surgery.

Does the persistence of pulsatile antegrade pulmonary blood flow following bidirectional Glenn procedure affect long term outcome? Evaluation shuntt cerebral oxygenation and perfusion with conversion from cavopulmnoary arterial-to-systemic shunt circulation to the bidirectional Glenn circulation in patients with univentricular cardiac abnormalities. This situation is advantageous because the resultant reduction in both ventricular preload and size allows occurrence of morphological changes in ventricular geometry and wall cavopulmonnary before the final stage of a Fontan procedure.

The bidirectional cavopulmonary Glenn shunt BDG is a commonly performed procedure for a variety of cyanotic congenital heart diseases that lead shutn to a single ventricle repair [1]. Bidirectional cavopulmonary connection without additional pulmonary blood flow in patients below the age of 6 months.

The idea was to delay as much as possible the need vavopulmonary Fontan and, hopefully, to avoid Fontan completely.

Although we did not run any statistics owing to small number patients; however, clinical and functional information from our experience confirms the safety of bidirectional cavopulmonary anastomosis and its efficacy in providing adequate oxygenation.

In patients with single ventricle physiology, the surgical protocol adopted in most centres follows a staging approach and includes BCPS and later Fontan completion. But your study found the exact opposite. Of note, because the SVC is connected to the pulmonary artery, SVC pressures reflect the pressures in the pulmonary circuit. The decision to conduct the procedure cavopulmomary CPB was made after complete evaluation with echocardiography and cardiac catheterization.

This confirms the results noted in other series in which patients were systematically entered in a staging to Fontan policy [ 15—17 ].

Thank you for submitting a comment on this article. Prevalence of reoperation bidrectional pathway obstruction after Fontan operation. Catheters placed in the right atrium directly measure common atrial pressure.

Continuous data were tested for normality using the Kolmogorov—Smirnov test. The BCPS has become a universal intermediate staging procedure between stage I palliation and the Fontan repair in infants born with a single ventricle.

A 1-month old infant died of severe cyanosis because of acute thrombosis of the cavopulmonary anastomosis. This ensured adequate oxygen saturation during performance of the Glenn anastomosis.

This was done using inotropic agents whenever required.

An alternative to the total cavo-pulmonary circulation in patients with a functionally single ventricle. Three of their patients had a seizure during the hospital stay; two of them apparently febrile in nature but one had permanent seizure. Finally, neurodevelopmental impairment is a common finding in patients with ccavopulmonary lesions who have palliative surgery and is due to modifiable and non-modifiable reasons.

The bidirectional cavopulmonary shunt.

It allows suhnt of the curve of the probability of bad outcome during follow-up as a function of age at BCPS. Superior vena cava – pulmonary artery shunt.

Associated procedures were required in four patients pulmonary angioplasty in three, AV valve replacement in one.
