Sudden postoperative death from ruptured intracranial vascular malformations in a patient receiving total parenteral nutrition.
A 30-year-old female patient underwent oesophagectomy and colonic transposition for multiple oesophageal strictures associated with epidermolysis bullosa dystrophica. On the 9th postoperative day, she had convulsions and died, whilst in a state of severe hyperglycaemia, which was presumably iatrogenically induced by total parenteral nutrition. Autopsy and subsequent histological examination revealed that the cause of death was acute subarachnoid haemorrhage from ruptured, intracranial cryptic arteriovenous malformations. Postmortem vitreous biochemistry confirmed that death had occurred in a state of hyperglycaemia. The pathology of intracranial vascular malformations and the medico-legal implications of this case are discussed.
