To evaluate selective embolization for management of posttraumatic priapism in preadolescent boys and color Doppler sonography for diagnosis of the causative lesion and for planning embolization.
Five preadolescent boys with posttraumatic priapism underwent selective angiography and embolization. Color Doppler sonography was performed in the last three patients.
Selective angiography showed an intracavernosal arteriovenous fistula in two patients, pseudoaneurysm of the cavernosal artery in two patients, and asymmetric cavernosal arterial flow in the other patient. After successful embolization, detumescence was achieved in all patients. Color Doppler sonography enabled localization and characterization of the lesion causing the priapism in the three patients.
Angiography with selective embolization is a safe and effective method to correct posttraumatic priapism in children. Color Doppler sonography is a valuable preangiographic study, as it allows for characterization and localization of the causative lesion and obviates diagnostic cavernosal aspiration.
评估选择性栓塞术治疗青春期前男孩创伤后阴茎异常勃起的效果，以及彩色多普勒超声在诊断病因性病变和规划栓塞术中的应用。
5例青春期前创伤后阴茎异常勃起男孩接受了选择性血管造影和栓塞术。最后3例患者进行了彩色多普勒超声检查。
选择性血管造影显示，2例患者存在海绵体内动静脉瘘，2例患者为海绵体动脉假性动脉瘤，另1例患者为不对称性海绵体动脉血流。成功栓塞后，所有患者阴茎均消肿。彩色多普勒超声能够对3例患者中导致阴茎异常勃起的病变进行定位和特征描述。
血管造影联合选择性栓塞术是纠正儿童创伤后阴茎异常勃起的一种安全有效的方法。彩色多普勒超声是血管造影术前一项有价值的检查，因为它能够对病因性病变进行特征描述和定位，避免了诊断性海绵体穿刺抽吸。
