Does sustained nitric oxide production via l-arginine administration ameliorate effects of intestinal ischemia-reperfusion?
Supplementation with l-arginine enhances NO production, resulting in reduced systemic endothelial dysfunction. This may act as a useful clinical adjunct in the management of trauma patients in preventing the development of ARDS and multiple organ failure.
Common iliac artery PTA is justified in most cases in which it is feasible. However, when PTAs are performed below the inguinal ligament, the results are markedly worse. One-year patency rates of PTA in this group of patients with threatened limbs are inferior to the patency rates of arterial bypass grafts, even when these bypasses are performed with a prosthetic material. PTA should not be considered as a primary treatment modality for patients with infrainguinal arterial occlusive disease who also have limb-threatening ischemia, except in unusual circumstances.
