Pre-operative embolisation of vertebral metastases has been known to effectively devascularise hypervascular vertebral tumours and to reduce intra-operative bleeding. However, the complications that occur during the procedure are rarely reported. This case study attempts to highlight one rare complication, which is epidural tumoural haemorrhage intra-procedure. It may occur due to the fragility of the tumour and presence of neovascularisation. A small arterial dissection may also have occurred due to a slightly higher pressure exerted during injection of embolising agent. Haemostasis was secured via injection of Histoacryl into the area of haemorrhage. The patient was able to undergo the decompression surgery and suffered no direct complication from the haemorrhage.
术前对椎体转移瘤进行栓塞已被证实可有效使高血运椎体肿瘤血管减少，并减少术中出血。然而，该操作过程中发生的并发症鲜有报道。本病例研究旨在突出一种罕见并发症，即术中硬膜外肿瘤出血。它可能是由于肿瘤的脆弱性和新生血管的存在而发生。在注射栓塞剂时施加的压力略高，也可能导致了小动脉夹层形成。通过向出血区域注射组织黏合剂实现了止血。患者能够接受减压手术，且未因出血出现直接并发症。
