Robotically Assisted Minimally Invasive Bypass Surgery

 

If you have coronary artery disease, bypass surgery can help. It creates a new pathway around the blocked part of your artery. This allows blood to flow again. In most cases, a healthy blood vessel (bypass graft) from another part of your body is used to create the new pathway. If you have more than one blockage, more than one bypass is done. For minimally invasive bypass surgery, incisions made in your chest are often much smaller than those made for traditional bypass surgery.

 

Reaching Your Heart

To get to your heart, one or more incisions must be made in your chest. An incision is made over your ribs or breastbone. The bones are then moved apart to allow access to the heart. Depending on the method your surgeon uses, small incisions may also be made near your neck and groin. After surgery, the bones are brought back together, and the incisions are sewn up.

Harvesting the New Artery

First, the left internal mammary artery is removed from underneath the chest wall. This is performed with the robot, through 3 small holes or ports on the left chest wall.

 

Attaching the Graft

First, the graft vessel is removed from your chest, leg, or arm. Then, one end of the graft is sewn to an opening in the coronary artery below the blockage. If a saphenous vein or radial artery is used, the other end is sewn onto the aorta. If a mammary artery is used, the other end is already attached to a branch of the aorta.
