Percutaneous coronary intervention on stenotic coronary lesions revolutionized treatment of coronary disease, but is associated with the risk of major adverse cardiac events. This prospective, nonrandomized, multicenter clinical feasibility and safety study enrolled 40 patients with 51 lesions at 4 centerswho underwent treatment of stenotic lesions with proximal emboli protection (Proxis system). Proxiswas successfully used 95%of the time, and embolic debris was qualitatively identified in all cases. Major adverse cardiac events occurred in 2 patients (5.0%): 1 late in-stent thrombosis resulting in death and 1 non-Q-wave infarction when a lesion was crossed before deployment of the Proxis system. Mean vessel occlusion time was 4.3±2.4 minutes. Native flow reversal was sufficient in 31 patients, with a mean aspirate volume of 11.8±6.5 ml. When the infusion catheter was used to augment reflow, mean occlusion time was 4.6 minutes. In conclusion, this trial is the first to demonstrate that retrograde blood flow can be achieved during proximal occlusion and that the Proxis system can be used safely during intervention of saphenous vein grafts and native coronary arterial lesions to capture embolic material.展开更多

We describe the course of a woman patient who had had a severe cutaneous necrotizing vasculitis for more than 10 years. Various immunsuppressants, including cyclophosphamide, had failed to improve the clinical course, although adequate doses were given for a sufficient period. Treatment with DADPS (diaminodiphenylsulfone, dapsone), however, finally led to complete remission of the severe and chronic vasculitic ulcerations. Indications for DADPS treatment of inflammatory cutaneous diseases are discussed, and an over view of cutaneous vasculitis is provided.展开更多
