The association of cavernous malformations and developmental venous anomalies (DVA) is well known, but the presence of arterial fistulous connection with the main venous collector has been reported in the literature only once. We report the unusual case of a hemorrhagic cavernous angioma associated with DVA characterized by a fine arterial supply to the main venous collector. During surgery, after the excision of the cavernous angioma, few small arterial feeders were found entering the main channel of the venous developmental anomaly. The presence of an arterial fistulous connection with the main venous collector of a DVA may be a possible mechanism involved in a higher bleeding potential of cavernous angioma.
海绵状血管畸形与发育性静脉异常（DVA）的关联已为人熟知，但动脉瘘与主要静脉引流器相连的情况在文献中仅被报道过一次。我们报告了一例罕见病例，即出血性海绵状血管瘤合并DVA，其特征是主要静脉引流器有精细的动脉供血。手术过程中，在切除海绵状血管瘤后，发现有少量小动脉分支进入静脉发育异常的主通道。动脉与DVA的主要静脉引流器之间存在瘘管连接，可能是海绵状血管瘤出血风险较高的一种潜在机制。
