Key result
Repeat dilatation of stented pulmonary arteries occurred at a mean of 15.5 months, mainly for growth adaptation, but also for intimal proliferation (17.5%) or external compression (25%).
Observational (n=38)
No
In pediatric patients, repeat dilatation of stented pulmonary arteries is frequently required to adapt to somatic growth, as well as to address intimal proliferation and external compression.
No takes yet. Share an insight, caveat, or question.
May warrant surveillance for reintervention in growing children; leaves optimal timing and indications open pending prospective data.
Katja Schneider (2002) conducted an observational in Pulmonary artery stenoses (n=38). Implantation of balloon expandable stents was evaluated on Reasons for repeat intervention and time intervals between interventions. Repeat dilatation of stented pulmonary arteries occurred at a mean of 15.5 months, mainly for growth adaptation, but also for intimal proliferation (17.5%) or external compression (25%).
