Spinal arteriovenous malformations and subarachnoid haemorrhage

Seventy patients with spinal arteriovenous malformations (AVMs) referred to the author over a 25-year period (1958-82), were equally divided between congenital, intradural and acquired, dural lesions. Amongst the intradural AVMs, were 22 with subarachnoid haemorrhage (SAH), a presenting feature in 18. The clinical findings in these 22 patients are tabulated, the radiological and operative findings indicated, and an account given of the overall outcome. Early operation is recommended, with a good prognosis and prevention of further haemorrhage in most cases. An extended follow-up has been maintained. The influence of menstruation, pregnancy and the puerperium on AVM symptoms is described.

Syringomyelia as a sequel to traumatic paraplegia

Ten cases of post-traumatic paraplegia are described in whom syringomyelia symptoms have supervened. Five patients have been operated upon after investigation. Operative results have been encouraging. A discussion of likely pathogenetic mechanisms is presented.
