Novel anastomotic method enables aortofemoral bypass for patients with porcelain aorta.
OBJECTIVE
Porcelain aorta is an indication for axillofemoral bypass. However, the procedure has definitive flaws. We present a new method for achievement of aortofemoral bypass.


METHODS
The portion of the distal aorta for anastomosis is wrapped with a double polytetrafluoroethylene mesh and fixed to the adventitia with continuous sutures. The adventitia of the anastomotic site is cut over the mesh until the calcified surface is disclosed. Margins of the mesh and the peeled adventitia are fixed along the anastomotic margin with continuous sutures. After the aorta and distal arteries are occluded with balloon catheters, an opening on the bared calcification is made with an airdrill and enlarged with a laminectomy rongeur. The anastomosis is performed between a graft and the mesh-reinforced adventitia with continuous sutures. Over 6 years, this method has been applied to nine patients with porcelain aorta who are diabetic or undergoing dialysis. The indications were disabling claudication in three patients and limb salvage in six patients.


RESULTS
No anastomotic complications or operative deaths were seen, and satisfactory mid-term results were obtained, with follow-up ranging from 3 to 62 months after surgery. One patient died of coronary heart disease 3 years after surgery, but the grafts retained a good function.


CONCLUSIONS
This method is safe and effective, and more liberal application of this method may help improve outcome and quality of life.
