Flat panel catheter angiotomography, a recently developed angiographic technique, offers a spinal equivalent to the venous phase obtained during cerebral angiography. This report of 8 clinical cases discusses the flat panel catheter angiotomography appearance of a type of spinal venous structure until now principally known through the analysis of postmortem material, transmedullary venous anastomosis. The illustrated configurations include centrodorsolateral, median anteroposterior, median anteroposterior with duplicated origin, and combined centrodorsolateral/median anteroposterior transmedullary venous anastomoses, while a pathologic example documents the potential role of transmedullary venous anastomoses as collateral venous pathways. Two of the reported configurations have not been previously documented. Transmedullary venous anastomoses are normal venous structures that need to be differentiated from spinal cord anomalies, such as intramedullary vascular malformations.
平板导管血管断层摄影术是一种最近开发的血管造影技术，它能提供与脑血管造影术中获得的静脉期相当的脊髓影像。这份包含8例临床病例的报告讨论了一种脊髓静脉结构在平板导管血管断层摄影术中的表现，这种结构目前主要是通过对死后材料（经髓静脉吻合）的分析为人所知。图示的结构包括中央背外侧、正中前后、起源重复的正中前后以及联合的中央背外侧/正中前后经髓静脉吻合，而一个病理实例证明了经髓静脉吻合作为侧支静脉通路的潜在作用。报告中的两种结构此前未曾有过记录。经髓静脉吻合是正常的静脉结构，需要与脊髓异常（如髓内血管畸形）相鉴别。
