Arterial Duct Stenting Deemed Beneficial to Neonates
Technique promotes more balanced pulmonary artery growth than conventional surgical shunt
MONDAY, Nov. 30 (HealthDay News) -- In neonates with congenital heart disease with duct-dependent pulmonary circulation (CHD-DPC), percutaneous arterial duct stenting is as effective as the modified Blalock-Taussig shunt in fostering pulmonary artery growth, according to a study in the Dec. 1 issue of the Journal of the American College of Cardiology.
Giuseppe Santoro, M.D., of the Second University of Naples in Italy, and colleagues studied 13 patients who underwent arterial duct stenting (group I) and 14 patients who received a modified Blalock-Taussig shunt (group II).
After 10 months, the researchers found that both procedures were associated with a significant increase of the Nakata index and McGoon ratio. However, they found that arterial duct stenting was associated with more balanced growth of the pulmonary arteries, most likely because of more uniform pulmonary blood flow.
"Thus, arterial duct stabilization could be proposed as the first-choice approach in the short-term palliation of these malformations, in view of spontaneous improvement or early and safer corrective surgery," the authors conclude. "This option might be advisable even if a longer-term palliation was needed, because the stent re-dilation could be successfully performed to prolong the lifespan of the stented duct."
