What are the symptoms of patent ductus arteriosus?

summary

The ductus arteriosus is located between the root of innominate artery and the right pulmonary artery. The peripheral arterial diastolic pressure decreases and the pulse pressure widens. This is due to the fact that in the diastolic period of the heart, the blood of aorta still flows into the pulmonary artery and the blood flow of systemic circulation decreases. What are the symptoms of patent ductus arteriosus? Let's talk about it

What are the symptoms of patent ductus arteriosus?

1、 A small number of patients with right to left shunt caused by significant pulmonary hypertension may only hear diastolic blowing murmur (relative pulmonary insufficiency) in the pulmonary valve area and have cyanosis, which is more obvious in the lower body than in the upper body.

2、 The most prominent sign is a loud continuous machine like murmur in the second intercostal space on the left edge of the sternum, occupying almost the whole systolic and diastolic period. It is the loudest at the end of systole and accompanied by tremor, spreading to the left upper chest and back. In some patients, the loudest noise may be in the first intercostal or the third intercostal. In infants with pulmonary hypertension or congestive heart failure, there may be no such continuous murmur, but only systolic murmur or no significant murmur due to the change of pressure gradient between aorta and pulmonary artery.

3、 The patients with larger shunt may have enlarged heart murmur boundary, enhanced apical pulsation, diastolic murmur in apical region (relative mitral stenosis), enhanced or split second heart sound in pulmonary valve region (but it is difficult to hear because it is covered by murmur), and peripheral circulation signs similar to aortic regurgitation, including pulse pressure widening, water rushing pulse, heart rate increasing, etc Capillary pulsation and peripheral arterial gunshot.

matters needing attention

The above is the symptoms of patients with patent ductus arteriosus related introduction, hope to help the majority of patients with friends. In the diagnosis of patent ductus arteriosus in the first time after effective treatment, general operation is the first treatment of patent ductus arteriosus, the treatment process should pay attention to diet, reasonable diet is of great help to the rehabilitation of patent ductus arteriosus disease.
