title: Embolisation of a renal artery pseudoaneurysm in a patient with renal malrotation and chronic aortic dissection.
abstract: BACKGROUND
  Renal artery pseudoaneurysms may arise as a complication of percutaneous nephrolithotomy (PCNL). Prompt recognition and treatment is essential to arrest haemorrhage which may be life threatening.
  
  
  METHODS
  A patient with chronic aortic dissection and malrotated right kidney underwent PCNL for right renal calculus. He developed delayed gross haematuria.
  
  
  METHODS
  Angiography showed a pseudoaneurysm arising from one of two right renal arteries, which in turn arose from the false lumen of the aortic dissection. The supplying artery was successfully embolised.
  
  
  CONCLUSIONS
  Renal artery pseudoaneurysms can be successfully treated with prompt angiography and embolisation, even in the presence of renal malrotation and aortic dissection.
