AORTIC DISSECTION





Aorta is the main artery in human body rising from left ventricles of the human heart. It extends downwards to abdomen and then split into two small arteries. It carries oxygenated blood to all parts of the body.


When a dissection in the inner wall of aorta takes place it forces the two layers split apart.  Sever abdomen pain or chest pain is the symptom of this occurrence. The other organs of the body will starve for oxygenated blood and cells will start dying.

When dissection occurs blood is forced between the two layers of aorta and causes widening of the layers. This type of disease is common with people with high blood pressure and connective tissue diseases. When blood pressure range is beyond 140/90 continuously it gives rise to dissection.




Aortic dissection is rare in the order of 3 to 100,000 people. Males dominate than women in getting this disease.  

People who have undergone open heart bypass surgery are susceptible to get aortic dissection.

Treatment for this disease is mostly surgical.  The objective of surgical treatment is to remove the most damaged portion and replace it with artificial rings, tubes or valves.
Replacement of damaged section of aorta is by sutureless vascular ring connector. It is made of reinforced dacron graft. Vascular ring connector is made of a titanic used as a stent in the vascular graft to gain immediate blood sealed.

The long term follow up in individuals who survive aortic dissection lies in absolute control of blood pressure. Systolic pressure below 130 carries better safety.
Of all the people with aortic dissection 40% die straight away before reaching hospital. 5 – 20% die during surgery or postoperative period.
