Embolisation with spirals. The first Fig. (a) shows an angiogram of the tortuous course of the bleeding vessels. The micro-catheter was inserted over the branch supplying the spinal cord in order to obtain a selective embolisation of the blood leaking branches with two micro-coils. The second angiographic image (b) demonstrated the closure of the haemorrhagic vessels and the patency of the radiculo-medullary spinal branch. The typical longitudinal course of the anterior spinal artery is shown in the right frame, where it runs in parallel to the spinal processes of the vertebrae
