摘　　要：目的提高对脾动静脉瘘影像和病理的认识。方法报告1例经手术和病理证实了的脾动静脉瘘。描述本病的DSA、CT和彩超的表现及病理所见,并做文献复习。结果病变发生于脾门处,DSA表现为脾动脉显影的同时,脾静脉和门静脉显影,并可见一血管样染色的囊状肿物;彩超表现为病灶内可探及五彩的血流信号,动、静脉频谱均可探及;CT平扫仅表现为脾门区软组织肿块;病理显示囊性肿物之壁由平滑肌和纤维组织构成,内衬内皮细胞。结论该病罕见,DSA和彩超检查具有诊断价值。Objective To improve imaging and pathological knowledge of splenic arteriovenous fistula（SAVF）. Methods The findings of DSA, CT, color ultrasonic and photomicroscopy in one patient with SAVF were studied and relative literature about SAVF was reviewed. Results The lesion originated from splenic hilus, and showed immediate opacification of an enlarged splenic and portal veins on selective splenic arteriography. On site of communication, a cystic mass of vascular-like opacification was seen. The findings on doppler ultrasound were particularly suggestive by the demonstration of the specific flow signals characteristics of the arterial and venous component of the lesion. On CT scanning without contrast the lesion showed a soft tissue mass in the splenic hilar. In pathological the wall of cystic lesion was composed of smooth muscle and fibrous tissue with endotheliurn. Conclusion SAVF is a rarely disease. DSA and Doppler ultrasound are effective examinations for the disease.
