We describe a rare case of a developmental venous anomaly associated with an arteriovenous malformation. A 20-year-old male presented with seizures and was diagnosed with left parietal arteriovenous malformation combined with developmental venous anomaly in the left frontal lobe, with the draining veins of both lesions converging into the same bridging vein despite the lesions affecting anatomically distinct areas. The patient underwent a craniotomy for resection of the arteriovenous malformation. However, progressive aphasia developed on the third postoperative day. Subsequent neuroimaging (CT and MRI) revealed thrombosis formation within the drainage vein of the developmental venous anomaly. The symptoms of aphasia gradually disappeared after anticoagulant therapy with low molecular weight heparin. This case adds to the current consensus that developmental venous anomalies have normal venous drainage. It also suggests that developmental venous anomalies are susceptible to hemodynamic changes.
我们描述了一例罕见的与动静脉畸形相关的发育性静脉异常病例。一名20岁男性因癫痫发作就诊，被诊断为左顶叶动静脉畸形合并左额叶发育性静脉异常，尽管这两个病变在解剖学上影响不同区域，但它们的引流静脉汇聚到同一条桥静脉。该患者接受了开颅手术切除动静脉畸形。然而，术后第三天出现进行性失语。随后的神经影像学检查（CT和MRI）显示发育性静脉异常的引流静脉内形成血栓。使用低分子量肝素进行抗凝治疗后，失语症状逐渐消失。该病例进一步支持了目前关于发育性静脉异常具有正常静脉引流的共识。它还表明发育性静脉异常易受血流动力学变化的影响。
