Twenty-six juvenile pigs underwent balloon de-endothelialization of the right femoral artery followed by an open bilateral lumbar sympathectomy ( n = 14) or a sham sympathectomy ( n = 12). Four weeks later flow was measured in femoral arteries. Animals were then killed and the femoral arteries were perfusion-fixed and harvested. Sympathectomy resulted in a significant ( P = 0.04) increase in flow in both the injured (right) and uninjured (left) femoral arteries. Sympathectomy did not inhibit intimal thickening following balloon injury: median (interquartile range) intimal area was 0.4 mm<jats:sup>2<\/jats:sup>(0.3\u20130.9) in the sympathectomy group versus 0.5 mm<jats:sup>2<\/jats:sup>(0.4\u20130.9) in the sham group. Sympathectomy did, however, result in a significant ( P = 0.02) increase in the lumen area: 1.1 mm<jats:sup>2<\/jats:sup>(0.8\u20131.8) versus 0.7 mm<jats:sup>2<\/jats:sup>(0.6\u20130.9).
