PURPOSE
To study cerebral developmental venous anomalies in patients with extensive venous malformations of the head and neck.
METHODS
All patients had undergone carotid angiography 10 to 15 years previously. Four-vessel cerebral angiography was carried out in 40 patients with venous malformations. All patients had a physical examination, 16 had CT, and 22 were examined with MR imaging. One patient had MR angiography.
RESULTS
Eighteen developmental venous anomalies were noted in 8 (20%) of 40 patients. Four patients had multiple anomalies, and these were bilateral in 1 patient. Developmental venous anomalies seen in association with cervicofacial, cutaneous, and mucosal venous malformations were remarkable in their absence of neurologic events and associated cavernoma; significance of ectatic venous convergence, extension, and preponderance of deep drainage routes; and frequency with which they multiple in occurrence.
CONCLUSION
Developmental venous anomalies have a remarkable prevalence of 20% in patients with extensive superficial venous malformations. Therefore, it is important to search for a cerebral developmental venous anomaly when confronted with a cervicofacial venous malformation.
目的
研究头颈部广泛静脉畸形患者的脑发育性静脉异常。
方法
所有患者在10至15年前均接受过颈动脉血管造影。对40例静脉畸形患者进行了四血管脑造影。所有患者均进行了体格检查，16例进行了CT检查，22例进行了磁共振成像检查。1例患者进行了磁共振血管造影。
结果
40例患者中有8例（20%）发现18处发育性静脉异常。4例患者有多处异常，其中1例为双侧异常。与面颈部、皮肤和黏膜静脉畸形相关的发育性静脉异常的显著特点是无神经事件及相关海绵状血管瘤；扩张的静脉汇合、延伸及深部引流途径占优势的意义；以及其多发的频率。
结论
在广泛的浅表静脉畸形患者中，发育性静脉异常的患病率高达20%，非常显著。因此，面对面颈部静脉畸形时，寻找脑发育性静脉异常很重要。
