2021年3月9日 · PDA stenting for almost all ductal dependent cyanotic newborns can be safe and effective and may have lower morbidity than selective PDA stenting. Current practice for newborns with ductal-dependent pulmonary blood flow is mostly surgical shunting with only selective patent ductus arteriosus stenting.

2013年4月1日 · Post–procedure transthoracic echocardiography showed a widely patent stent with unrestricted flow across the stented PDA in all patients. The right ventricular function improved immediately after the procedure. All patients were discharged on the next day.

2024年10月29日 · We present three cases of PDA stenting involving several types of PDA morphologies using the femoral vessel approach and introduce a highly successful technique. Case 1: A 3-day-old female with pulmonary atresia and an intact ventricular septum had two stents implanted via the femoral artery (FA) in a PDA originating from the descending aorta.

2022年1月10日 · Background: Patent ductus arteriosus (PDA) stent placement and systemic-pulmonary surgical shunt procedure can both be performed as palliation for infants with duct-dependent pulmonary circulation.

In this article, we will focus on PDA stenting for ductal-dependent pulmonary blood flow. Cross-sectional images and advance post-processing are emerging as important tools in pre-operative and peri-operative planning and support for PDA stenting.

PDA Stents Percutaneous stent implantation can be performed to maintain ductal patency in patients with ductal-dependent pulmonary blood ow. Details of the ductal anatomy are vital to obtain prior to the procedure. Using TTE, the origin and insertion of the ductus, in addition to PA anatomy, should be ascertained.

PDA morphology: Origin/type of PDA; site of insertion; tortuosity and presence of branch PA stenosis. Stenting strategy: Route of stenting – transfemoral, transaxillary or transcarotid. PDA proximal transverse arch. • Recommended in difficult anatomy.

2019年4月1日 · A classification scheme for PDA morphology was devised based on a tortuosity index (TI)-Type I (straight), Type II (one turn), and Type III (multiple turns). A subtype classification was used based upon the ductal origin.

2022年4月14日 · Percutaneous patent ductus arteriosus (PDA) stenting is a therapeutic modality in patients with duct-dependent pulmonary circulation with reported success rates from 80–100%. The current study aims to assess the outcome and the indicators of success for PDA stenting in different ductal morphologies using various approaches.

2021年6月1日 · In the current era, patent ductus arteriosus (PDA) stenting is advantageous to the Blalock- Taussig- Thomas (BTT) in most instances. Procedural advances and understanding of ductal morphology have facilitated PDA stenting in recent years, albeit with a …
