Acute ischemic ulcers are real superficial skin infarcts due to capillary thrombosis. The remainder of the limb has a satisfactory blood supply and healing may be obtained, whatever the eetent of the ulcers, by methods aimed at correcting the general disorders in question and by local treatments in preparation for skin grafts. The prognosis of these ulcers is not as bad as that of chronic arteritis ulcers, which are caused by an important hypovascularization of the limb.
急性缺血性溃疡是由毛细血管血栓形成导致的真正的浅表性皮肤梗死。肢体的其余部分血液供应良好，无论溃疡程度如何，通过旨在纠正相关全身紊乱的方法以及为皮肤移植做准备的局部治疗，溃疡都有可能愈合。这些溃疡的预后不像慢性动脉炎溃疡那么糟糕，慢性动脉炎溃疡是由肢体严重血管化不足引起的。
