A 10-year-old KWPN (Royal Warmblood Studbook of the Netherlands) gelding was euthanized after developing severe neurological symptoms preceded by severe epistaxis during laser treatment for progressive ethmoid haematoma (PEH) in the right nasal cavity. Postmortem examination of the head revealed a large amount of clotted blood between the right ventral and dorsal conchae in the nasal cavity and acute haemorrhage in the right subarachnoid space. Histologically, there was moderate, acute polioencephalomalacia in the neuropil adjacent to the haemorrhage. The haemorrhages were most likely caused by the laser treatment and therefore should be considered a possible complication that could lead to severe peracute neurological symptoms.
一匹10岁的荷兰温血马（KWPN，荷兰皇家温血马登记册）在右侧鼻腔进行渐进性筛窦血肿（PEH）激光治疗时，先出现严重鼻出血，随后出现严重神经症状，最终实施了安乐死。头部尸检发现鼻腔右侧腹侧和背侧鼻甲之间有大量凝血，右侧蛛网膜下腔有急性出血。组织学检查显示，出血部位相邻的神经纤维中有中度急性脑软化。出血很可能是由激光治疗引起的，因此应被视为可能导致严重超急性神经症状的一种并发症。
