Blood flow patterns in the anterior cerebral arteries were studied in eight preterm infants with patent ductus arteriosus and left-to-right shunts. A noninvasive Doppler technique was used to obtain the blood flow patterns and to calculate a pulsatility index. Advancing diastolic blood flow was decreased in all eight infants, and two demonstrated retrograde anterior cerebral artery flow during diastole. Following ductal closure, the diastolic flow in the anterior cerebral arteries increased significantly, reaching levels seen in normal infants. These observations demonstrate that infants with patent ductus arteriosus and left-to-right shunts may have abnormal cerebral hemodynamics which return to normal following ductal closure.

Background: Ductal-dependent cyanotic newborns require a secure source of pulmonary blood flow. There has been a recent migration to selective ductal (patent ductus arteriosus [PDA]) stenting for some of these children. Universal (nonselective) ductal stenting for all infants with ductal-dependent pulmonary blood flow is controversial. We examine outcomes from a single center with this practice change. Methods: We compare outcomes of all ductal-dependent pulmonary blood flow infants (2013–2020 [January–June]) in the following treatment eras: Era 1 (selective PDA stenting; 2013–2017) or Era 2 (universal PDA stenting; 2018–2020 [January–June]). Results: Eighty-eight patients (Blalock-Taussig shunt, n=41; PDA stent, n=47) met inclusion criteria. In Era 1, most received Blalock-Taussig shunt (62% [41/66]). In Era 2, all received PDA stents (100% [22/22]). There were more females in Era 2, but otherwise no demographic differences between eras. There were no differences in mortality, treatment failures, complications, or reinterventions between eras. Postprocedure length of stay was shorter in Era 2 (8 versus 22 days, P =0.02). There were less surgical revisions for PDA stent patients (2% versus 20%, P =0.02). Postprocedure recovery surrogate end points favored Era 2 and PDA stenting. Additional analysis revealed PDA stent (compared with Blalock-Taussig shunt) patients had shorter post-procedure (10 versus 29 days, P ≤0.001) length of stay and more symmetrical branch pulmonary arteries (0.9 versus 0.7, P =0.001) at subsequent surgery. Conclusions: PDA stenting for almost all ductal dependent cyanotic newborns can be safe and effective and may have lower morbidity than selective PDA stenting.

The effect of the patent ductus arteriosus on the circulation and on the arterial blood gases and pHs has been studied. The pulmonary blood flow diminished 19.6 to 61.8% following ligation in 12 cases examined. The blood volume diminished following closure of the ductus in most cases. Likewise, the heart rate lessened and the pulse pressure was lower after surgery. Arterial oxygen saturation was low preoperatively in some cases and in most instances postoperatively, and this low value sometimes persisted. Some aspects of the data presented have been discussed in detail.

We report two cases of newborns with critical pulmonary stenosis having intact ventricular septum, who underwent pulmonary valve balloon valvuloplasty followed by banding of a patent ductus arteriosus. Transcatheter pulmonary valvuloplasty was performed one week after delivery. Following the procedure, both developed “circular shunting” as a consequence of left-to-right ductal flow and pulmonary regurgitation. This in turn caused increased blood flow into a dysfunctional right ventricle and low systemic cardiac output syndrome. The PDA banding was performed urgently as a rescue measure in order to restore systemic flow while still maintaining some duct-dependent pulmonary blood flow. This approach resolved the circular shunting. Outcome was favorable in both the patients.
