title: Vascular injury during lumbar disc surgery. Report of two cases; a review of the literature.
abstract: Iatrogenic vascular injuries are unusual complications of lumbar disc surgery. The incidence of such injuries is very low but probably underestimated because clinical manifestations may be extremely variable depending on the extension of trauma. Diagnosis is suspected when early signs of retroperitoneal haemorrhage appear, but may often be delayed for weeks or years due to formation of a pseudoaneurysm or an arteriovenous fistula which may be of gradual onset and produce initially only a few symptoms. Prompt diagnosis and aggressive treatment can improve the current mortality rate of more than 50%. Two cases are described that illustrate the full spectrum of acute and chronic manifestations of such injuries. One case of acute haemorrhage due to arterial trauma was immediately detected and the other case with arteriovenous fistula was recognized several years post-operatively.
