Abstract

Intradural spinal cord arteriovenous shunts are challenging vascular lesions with poor prognosis if left untreated. Therapeutic options include endovascular treatment, microsurgery or a combined approach. Surgical approaches are more complex if the lesions are located anteriorly and supplied by the anterior spinal artery (ASA). ASA can also vascularize shunts located on the posterior surface of the spinal cord either by transmedullary arteries, pial circumferential arteries or, if affecting the lower portions of the cord, by the anastomotic channels of the basket. Each of these vessels can be used for endovascular navigation to reach the shunts with good results if appropriate anatomical rules are followed. We describe here some technical considerations based on the anatomical analysis for the embolization of posterior spinal cord arteriovenous shunts vascularized by the anterior spinal artery.

通过脊髓前动脉进行脊髓后房室分流的血管内方法。
脊髓硬膜内动静脉分流是一种具有挑战性的血管病变,如果不及时治疗,预后很差。治疗方法包括血管内治疗、显微外科手术或综合治疗。如果病变位于前方并由脊髓前动脉(ASA)供血,手术方法则更为复杂。脊髓前动脉还可以通过经髓动脉、髓周动脉或(如果影响到脊髓下部)篮状吻合通道为位于脊髓后表面的分流提供血管。如果遵循适当的解剖规则,这些血管均可用于血管内导航以到达分流处,并取得良好效果。在此,我们将根据解剖学分析介绍栓塞脊髓前动脉血管的脊髓后动静脉分流的一些技术注意事项。
