PURPOSE
Endovascular treatment of spinal AVMs is limited by low complete cure rates. Transarterial extensive treatment with liquid embolics carries the risk of clinically relevant ischemic complications. We report two cases of symptomatic spinal AVMs treated by a transvenous approach with retrograde pressure cooker technique.
METHODS
In two selected cases, transvenous navigation aimed at retrograde pressure cooker embolization.
RESULTS
Retrograde venous navigation was possible with two parallel microcatheters, and the pressure cooker technique with ethylenvinylalcohol-polymer was applicable in both cases. One AVM was occluded completely, and one subtotally due to a second draining vein. No clinical complications occurred.
CONCLUSION
A transvenous approach for embolization with liquid embolics may offer advantages in treating certain spinal AVMs.
目的
血管内治疗脊髓动静脉畸形的完全治愈率较低。动脉内广泛使用液体栓塞剂治疗有发生临床相关缺血性并发症的风险。我们报告两例采用经静脉逆行压力锅技术治疗有症状的脊髓动静脉畸形。
方法
在 2 例选定的病例中，采用经静脉逆行导航技术进行压力锅栓塞。
结果
采用两条平行微导管进行逆行静脉导航是可行的，乙烯-乙烯醇共聚物的压力锅技术在两种情况下均适用。1 例动静脉畸形完全闭塞，1 例因第二引流静脉闭塞近全闭。无临床并发症发生。
结论
使用液体栓塞剂进行经静脉栓塞的方法可能为治疗某些脊髓动静脉畸形提供优势。
