A positive neural ultrasound foam test is more serious. Consider the association of patent foramen ovale not closed and atrial septal defect, which may cause cerebral infarction and heart failure if left untreated.
1. Unclosed foramen ovale: The onset of this disease may cause the pressure of right atrium to exceed that of left atrium, which results in abnormal right-to-left shunting of blood flow in the heart, and this condition may cause migraine, cerebral infarction, hypoxemia, etc.
2. Atrial septal defect: At the onset of this disease, due to insufficient blood flow in the body circulation, patients may have symptoms such as pallor, generalized weakness, chest tightness and shortness of breath after activity, which may cause arrhythmia and heart failure if not treated in time, and cause serious impact on patients’ health.
Positive nerve ultrasound foam test should be treated under the guidance of physician’s interview to clarify the cause of the disease.
