RATIONALE
Spinal dural arteriovenous fistulas (SDAVFs) are acquired arteriovenous shunts that occurs in the layers of the dura. Double-level SDAVFs with multiple draining veins are extremely rare. We present a rare case of double-level SDAVFs with multiple draining veins which was successfully managed in our hybrid theater.
PATIENT CONCERNS
A 54-year-old male presented with 6-week progressive bilateral lower extremity paresis accompanied by urinary incontinence.
DIAGNOSES
Selective spinal angiography revealed multiple DAVFs at T6 and T9.
INTERVENTIONS
Surgery was performed in our hybrid operating room because of complexity of both fistulas. Intraoperatively, angiography was performed to identify the SDAVFs prior to electrocoagulation and removed.
OUTCOMES
The patient recovered with no further neurological deficits and 2 years follow-up revealed the patent is well and go about his daily duties.
LESSONS
Intraoperative angiography is very helpful in identify the SDAVFs prior to electrocoagulation and removed.
理论依据
脊髓硬脊膜动静脉瘘（SDAVF）是后天性动静脉分流，发生于硬脊膜层。具有多条引流静脉的双节段SDAVF极为罕见。我们报告了1例具有多条引流静脉的双节段SDAVF罕见病例，该病例在我们的复合手术室成功得到治疗。
患者情况
一名54岁男性，出现双侧下肢进行性无力6周，并伴有尿失禁。
诊断
选择性脊髓血管造影显示T6和T9节段存在多个动静脉瘘。
干预措施
由于两个瘘口均复杂，在我们的复合手术室进行了手术。术中，在电凝和切除之前进行血管造影以识别SDAVF。
结果
患者康复，无进一步神经功能缺损，2年随访显示患者情况良好，能进行日常活动。
经验教训
术中血管造影在电凝和切除之前识别SDAVF非常有帮助。
