A new suture technique for reconstruction of intercostal arteries during thoracoabdominal aortic aneurysmal surgery.
Reconstruction of several intercostal arteries is inevitable in surgical treatment of thoraco-abdominal aortic aneurysm. A Dacron inverted-Y shaped graft was fashioned by cutting one of two graft legs and making an elliptical patch, like a cobra-head. Once the elliptical patch was sutured to the orifices of the intercostal arteries (usually from T9 to T12) with running sutures, selective intercostal arterial perfusion was initiated. After completion of aneurysmectomy, the distal end of the elliptical patch graft was sutured to the main tube graft. This method is easier and faster and results in a decreased incidence of spinal cord injury.
