A lesion of the lumbo sacral plexus may result from an inadvertent intra-arterial injection of vasotoxic drugs into one of the gluteal arteries. Symptoms and follow-up of three cases are reported. The neuropathy is attributed to a toxic endarteritis with retrograde propagation of spasm and thrombosis. Swelling an bluish discoloration of the buttocks ("embolia cutis medicamentosa") as well as an impaired circulation in the homolateral leg are associated with the neurological syndrome in fully developed cases and makes possible a correct diagnosis.
腰骶丛损伤可能是由于无意中将血管毒性药物动脉内注射到臀动脉之一所致。本文报告了三例病例的症状及随访情况。这种神经病变归因于毒性动脉内膜炎伴痉挛和血栓形成的逆行扩散。在病情充分发展的病例中，臀部肿胀及皮肤发蓝（“药物性皮肤栓塞”）以及同侧腿部血液循环障碍与神经综合征相关，从而有可能做出正确诊断。
