The subaortic course of the innominate vein is a variant of the normal course of the innominate vein, which is a large vein that drains blood from the head and neck. In the subaortic course, the innominate vein passes behind the aorta before entering the superior vena cava. This variant is seen in approximately 10% of the population.

The symptoms of Subaortic course of innominate vein include chest pain, shortness of breath, palpitations, dizziness, and fatigue. Other symptoms may include swelling of the legs and feet, coughing, and difficulty breathing. In some cases, the patient may experience a rapid heart rate or arrhythmia.

The most common cause of a subaortic course of the innominate vein is a congenital anomaly, which is present at birth. This anomaly is caused by the abnormal development of the aortic arch during fetal development. Other causes of a subaortic course of the innominate vein include trauma, infection, and tumors.

1. Surgery: Surgery is the most common treatment for subaortic course of innominate vein. The goal of the surgery is to create a new pathway for the vein to travel through, allowing it to bypass the obstruction.

2. Medication: Medications such as diuretics and vasodilators may be prescribed to help reduce the pressure in the vein and improve blood flow.

3. Interventional Radiology: Interventional radiology techniques such as angioplasty and stenting may be used to open up the blocked vein and improve blood flow.

4. Catheterization: Catheterization may be used to measure the pressure in the vein and assess the severity of the obstruction.

5. Lifestyle Changes: Making lifestyle changes such as quitting smoking, exercising regularly, and eating a healthy diet can help

At this time, there is no known cure or medications for subaortic course of innominate vein. Treatment for this condition typically involves surgical intervention to correct the abnormal course of the vein. This may involve bypassing the vein or rerouting it to a more normal course. In some cases, the vein may be removed entirely. Your doctor will be able to provide more information about the best treatment option for your particular case.
