Hong Kong researchers said that Asian doctors should practice less invasive surgery for by pass surgery. They say that the traditional surgery though is not harmful can increase the chances of exposing patients to innumerable infections. Most of the Asians suffer from diabetes and are prone to infections. In the traditional method the great saphenous vein is removed from the leg and grafted onto the heart.
This enhances the blood flow to the heart muscle through the newly fixed blood vessel. But the problem is that there is a rise in the rate of post-operation infection and trauma. The great saphenous vein is removed by making a cut which runs deep (2-inches) from the ankle to the top of the inner thigh. In US endoscopy is used to harvest the vein which requires small incisions (2 cm deep).
According to the study conducted by Timmy Au, a cardiothoracic surgeon at Hong Kong's Grantham Hospital said that up to 40 % of 74 bypasses patients were diabetic. This shows that there is an increase in diabetic rate among the Asians especially Chinese. Hence the risk of infection is very high which are dangerous because during or after surgery the body's normal ability to fight infections is impaired. Additionally it is very difficult to control the deterioration if there is an increase in the glucose control.
The common infection that occurs after the surgery is that of the leg infection which will later spread to other parts of the body. Severe infections are rare, but it is very difficult to revive the patient after such infections. But this new less invasive method is become very popular among the richer nations in the West it is not so in the east due to the cost factor. But in conclusion the researcher says that in case of implementing this technique one can reduce the post-operation care and the overall cost will be lower.
