Ischemic neuropathy of the sciatic nerve without preceding vascular surgical procedures is a rare condition and may be due to arterial occlusion in one limb.
We present two cases with acute onset of pain and sensory symptoms such as pins and needles and numbness in the foot with no or mild motor symptoms. In the neurological work-up, electrophysiological signs of axonal neuropathy of both peroneal and tibial nerves were demonstrated and T2 hyperintensity was seen in the distal sciatic nerves on MR neurography as well as signs indicating arterial thrombosis in the corresponding vessels. Recanalization was obtained in both patients angiographically with significant improvement in one patient.
Spontaneous arterial occlusion of major or peripheral arteries is a rare but important cause of acute onset of single or multiple axonal mononeuropathies of one extremity. Recognition of this infrequent cause is essential since it requires immediate and specific therapeutic options.
没有先前血管外科手术的坐骨神经缺血性神经病是一种罕见的情况，可能是由于一条肢体的动脉阻塞引起的。
我们介绍了两例患者，他们均出现急性足部疼痛和感觉症状，如刺痛和麻木，且运动症状轻微或无。在神经学检查中，显示出腓总神经和胫神经的轴索性神经病的电生理学征象，磁共振神经成像显示远端坐骨神经的 T2 高信号，以及相应血管中的动脉血栓形成征象。在两名患者中，均通过血管造影获得了再通，其中一名患者的情况显著改善。
主要或外周动脉的自发性动脉闭塞是急性单侧或多侧单一轴索性神经病的罕见但重要病因。认识到这种不常见的病因至关重要，因为它需要立即采取特定的治疗方法。
