G. Patrick Clagett, chief of vascular surgery at University of Texas-Southwestern (UT-S), has pioneered a new technique, called the neo-aortoiliac system (NAIS). The technique proves that replacing the infected veins with the body’s own veins is better for grafting than the synthetic ones.

Clagett stated that the operation has gained worldwide favor, according to an UT-S release.

Using synthetic grafts are preferred first in surgery in patients with PAD and aortic aneurysms. The new method restores blood circulation in the legs in PAD patients and in aneurysm patients the weakened aortic wall is replaced thereby preventing rupture.

Clagett found that chances of infection in patients grafted with parts from own body were lesser than synthetic grafts. This technique lowered the rate of infections also. Clagett concluded this after conducting a study on about 187 patients, who were treated for aortic graft.

Journal of Vascular Surgery carried the findings.
