title: [Intraabdominal complications in the lumbar disc surgery].
abstract: BACKGROUND
  : Removal of a lumbar disc herniation is, at present, the most frequent surgical procedure, related to the spine in Neurosurgical Departments. It carries a very low rates of complications and a short postoperative hospital stay. However, in spite of their rarity, serious adverse intraoperative complications may occur, so we must be aware of its existence in order to make an early diagnosis and treatment to prevent a fatal outcome. It is important to ensure that the patient understand the possible complications and obtaining written consent to avoid later medico-legal problems.
  
  
  METHODS
  We report two cases with typical lumbociatic pain secondary to lumbar disc herniation operated at our Department, that resulted in intraoperative complications, due to perforation of intraabdominal structures. Initially, the patients underwent planned flavectomy, followed by simple disc removal. However, symptoms of abdominal pain and systemic hypotension in each case, began some hours later. Early diagnosis was achieved using abdominal-pelvic CT scan, showing an intestinal perforation in one patient and a tear of both iliac artery and vein in the other. In both, an urgent laparotomy was performed by colleagues from the Department of General and Vascular Surgery, with surgical repair. The final outcome was good and both are asymptomatic.
  
  
  CONCLUSIONS
  Surgical removal of the lumbar disc herniation is a very effective procedure, but is not free from certain severe though rare complications. Intestinal perforation and vascular tears are two possible complications to suspect if abdominal pain or systemic arterial to suspect if abdominal pain or systemic arterial urgent surgical repair of such complications. It is of vital importance that the patient knows the existence of such complications and so obtain a written consent.
