[Transcatheter exclusion of a giant aneurysm of the left pulmonary artery using covered stents]. / Exclusion d'un anévrisme géant de l'artère pulmonaire gauche par cathétérisme interventionnel: utilisation de stents couverts.

ABSTRACT

An 11 year-old boy with an Alagille syndrome was referred for an urgent echocardiography because of new onset of febrile hemoptysis. Follow-up in our institution to that point had shown severe hypoplastic pulmonary arteries. The diagnosis of tricuspid endocarditis complicated by pulmonary embolisms and aneurysm of the left pulmonary artery was done. Despite effective antiobiotics, the evolution was marked by rapid progression in size of the left pulmonary aneurysm. Since the surgery was not an option because of high risk of death, this aneurysm was treated by a trans-catheter technique using covered stents (CP stents, Numed Inc). Its exclusion allowed to stop its progression in size and to avoid its rupture.
