Taking into account the number of craniotomies performed every day around the world, iatrogenic aneurysm post-craniotomy is extremely rare with only anecdotal cases reported in literature. We report an iatrogenic aneurysm affecting a cortical vessel which probably developed during dural closure of a conventional craniotomy. The aneurysm was discovered 6 months after surgery on a routine control angiography. The patient was successfully treated by trapping the parent vessel and excising the aneurysm. Histopathological findings were compatible with a true type of traumatic aneurysm. The possibility of this rare condition occurring highlights the risk of arterial injury during craniotomy.
考虑到全球每天进行的开颅手术数量，开颅术后医源性动脉瘤极为罕见，文献中仅有个别病例报道。我们报告一例医源性动脉瘤累及皮质血管，可能在传统开颅手术硬脑膜关闭过程中形成。该动脉瘤在术后6个月的常规对照血管造影检查中被发现。通过阻断载瘤血管并切除动脉瘤，患者得到成功治疗。组织病理学检查结果符合真性创伤性动脉瘤。这种罕见情况发生的可能性凸显了开颅手术期间动脉损伤的风险。
