Patent Ductus

A central shunt (CS) was an important surgery of systemic-to-pulmonary shunt (SPS) for the treatment of complex congenital heart diseases with decreased pulmonary blood flow (CCHDs-DPBF). There was no clear conclusion on how to deal with unclosed patent ductus arteriosus (PDA) during CS surgery. This study expanded the knowledge base on PDA by exploring the influence of the closing process of the PDA on the hemodynamic parameters for the CS model. The initial three-dimensional (3D) geometry was reconstructed based on the patient’s computed tomography (CT) data. Then, a CS configuration with three typical pulmonary artery (PA) dysplasia structures and different sizes of PDA was established. The three-element windkessel (3WK) multiscale coupling model was used to define boundary conditions for transient simulation through computational fluid dynamics (CFD). The results showed that the larger size of PDA led to a greater systemic-to-pulmonary shunt ratio ( Q S / A ), and the flow ratio of the left pulmonary artery (LPA) to right pulmonary artery (RPA) ( Q L / R ) was more close to 1, while both the proportion of high wall shear stress (WSS) areas and power loss decreased. The case of PDA nonclosure demonstrates that the aortic oxygen saturation (Sao2) increased, while the systemic oxygen delivery (Do2) decreased. In general, for the CS model with three typical PA dysplasia, the changing trends of hemodynamic parameters during the spontaneous closing process of PDA were roughly identical, and nonclosure of PDA had a series of hemodynamic advantages, but a larger PDA may cause excessive PA perfusion and was not conducive to reducing cyanosis symptoms.

AbstractDuctus arteriosus is an essential component of fetal circulation. Due to occurring changes in the cardiopulmonary system physiology after birth, ductus arteriosus closes. Patent ductus arteriosus can be closed by medical or invasive (percutaneous or surgical) treatment methods. Percutaneous or surgical closure of patent ductus arteriosus can be performed for the cases that medical closure failed. Surgical treatment is often preferred method for closure of patent ductus arteriosus in the neonatal period. The most common surgical complications are pneumothorax, recurrent laryngeal nerve injury, bleeding, and recanalisation. A very rare surgical complication is left pulmonary artery ligation that has been presented in a few cases in the literature. Echocardiography control should be performed in the early post-operative period, especially in patients with clinical suspicion. If reoperation is required, it should never be delayed. We report a newborn patient whose left pulmonary artery ligated accidentally during patent ductus arteriosus closure surgery and surgical correction of this complication at the early post-operative period.

Pulmonary artery pressure is one of the most important parameter for evaluating the status of pulmonary vascular bed for patients of PDA, which helps in formulating treatment strategy. This study was carried out in National Institute of Cardiovascular Diseases and Hospital (NICVD) and National Centre for Control of Rheumatic Fever and Heart Diseases, Dhaka, Bangladesh. Pulmonary artery pressure was recorded noninvasively using Doppler echocardiography and the it was correlated with those obtained from haemodynamic studies done at cardiac catheterization. Estimation of pulmonary artery pressure using Doppler derived measurement of pressure gradient across patent ductus arteriosus correlated well with that of simultaneous catheterization measured values. Doppler echocardiography is a cheap, simple, noninvasive bedside test for measuring pulmonary artery systolic and diastolic pressure in patient with PDA.
