title: [Roles of arterial dysplasia, chronic ergotism and other factors in a case multiple spontaneous arterial dissections].
abstract: BACKGROUND
  Spontaneous dissection of cervical and visceral arteries are rare and usually associated with an underlying arterial disease.
  
  
  METHODS
  The authors report the unusual case of a 50-year-old woman with high blood pressure who presented spontaneous dissection of cervico-cephalic, renal and hepatic arteries and of the descending aorta. She had been taking ergotamine tartrate for ten years for migraine. She also suffered from Raynaud's syndrome worsened by treatment.
  
  
  CONCLUSIONS
  The respective roles of arterial dysplasia, chronic ergotism, renovascular hypertension and migraine are discussed.
