Although damage to the veins of Batson's epidural plexus is usually considered the origin of bleeding in traumatic lumbar puncture, a lesion of these veins would not explain the cases in which postmortem examination shows blood confined to the subdural and subarachnoid spaces. In two patients who had lumbar punctures a few days before death, there was subarachnoid hematoma of the cauda equina at autopsy. In one of these cases, the radicular vessels were shown to be the source of bleeding. Spinal subarachnoid and subdural hemorrhages after lumbar puncture may be due to laceration of radicular vessels by the spinal needle.
尽管通常认为巴特森硬膜外丛静脉损伤是创伤性腰椎穿刺出血的起源，但这些静脉的损伤并不能解释尸检显示血液局限于硬膜下和蛛网膜下腔的病例。在两名死亡前几天进行过腰椎穿刺的患者中，尸检发现马尾神经有蛛网膜下腔血肿。在其中一例中，显示神经根血管是出血来源。腰椎穿刺后脊髓蛛网膜下腔和硬膜下出血可能是由于脊髓穿刺针撕裂神经根血管所致。
