  • The dilated part of the aorta will be replaced with a tube-shaped Gortex graft by the surgeon during this operation.
  • Blood flow to the spinal cord and other vital organs supplied by the aorta is maintained at the same time.
  • Many steps, such as draining spinal fluid can be taken by your surgeon during surgery to prevent damage to the spinal cord.
  • Surgery is recommended by your surgeon based on different factors. These include:
  • The diameter of the aorta, that is, how much it has stretched beyond normal size?
  • If you have underlying connective tissue disease such as Loeys-Dietz Syndrome, Marfan's Syndrome or Ehlers-Danlos Syndrome.

Procedure for Thoraco Abdominal Aneurism Repair:


  • An IV and general anesthesia will be given to you so that you will sleep through the procedure.

  • You may need this lumbar drain for 1 to 3 days after surgery to protect your spine.
  • A heart-lung machine will be connected to do the work of your heart and lungs, which also allows your surgeon stop blood flow to the surgical site so they can work in a still, bloodless field.
  • An incision will be made between your ribs on the left side of the chest. 
  • The length of the incision depends on how much of the aorta needs repaired.
  • The diseased part of the aorta will be removed and replaced with a tube-shaped woven fabric graft.
  • Blood vessels that branch off of the aorta may also need to be repaired. A piece of vein from your leg will be used to do this.
  • The incision will be closed with stitches under the skin by your surgeon once the repair is complete.
  • Medicine will be given by your care team to help you manage post-operative pain.
