arterial trunk
Truncus arteriosus is a congenital heart disease that occurs from birth, characterized by the presence of a single blood vessel (which is named after the disorder itself) at the outlet of the right and left ventricles, unlike the normal design . which has the aorta and the pulmonary artery.
In addition to this anomaly, the arterial trunk is usually accompanied by a hole that connects both ventricles, which carries a mixture of oxygenated and deoxygenated blood . Most often, the lungs receive more blood than necessary and, if effective treatment is not given in time, the following can occur:
- Breathing can be affected due to the accumulation of fluid in the lungs caused by the aforementioned excess blood.
- The blood vessels that connect the lungs can be permanently damaged , making it increasingly difficult to pump blood (pulmonary hypertension), putting the person's life at risk.
Among the main symptoms of arterial trunk are the following:
- Failure or delay in development.
- Bluish skin (cyanosis).
- Lethargy.
- Fatigue.
- Eating disorders .
- Difficulty breathing (dyspnea).
- Breathing too quickly (tachypnea).
- The ends of the fingers may widen (hippocratic fingers).
Diagnosis and treatment
Doctors usually detect the arterial trunk by hearing a murmur during auscultation of the heart. Some of the tests associated with this disorder are: echocardiography; electrocardiogram (ECG); MRI of the heart; cardiac catheterization, which is not usually used unless it serves to define the diagnosis in very particular cases; chest x-ray.
Treatment of the arterial trunk requires a surgical operation, through which the malformation is corrected, providing the patient with the two arteries that he should have had since birth. The truncal vessel is usually dedicated to the role of the aorta, using an external tube or tissue to recreate the pulmonary artery. Additionally, the hole between both ventricles closes.
