title: [Intracerebral haemorrhage by cerebral hyperperfusion after carotid angioplasty in a tandem lesion. A case report].
abstract: Intracerebral hemorrhage (ICH) by hyperperfusion after carotid angioplasty has a frequency of 1.2 % - 4.4% in the literature. Until now no case of ICH after carotid angioplasty in a tandem lesion has been reported. We present the case of a patient who suffered an ICH due to the hyperperfusion syndrome, after carotid angioplasty of two stenotic lesions of the left internal carotid artery (ICA) (intracranial and extracranial). He was a 58 year old man who suffered repetitive left carotid TIA despite being treated with antiplatelet therapy. An angiogram showed 76 % extracranial stenosis and 96 % intracranial stenosis of the left ICA as well as 59 % extracranial stenosis of right ICA. Angioplasty with stenting of the two stenosis of the left ICA was performed. After 48 hours of the angioplasty, the patient presented a massive ICH and died a few hours later. ICH by hyperperfusion is an infrequent complication of the carotid angioplasty. The risk factors of the ICH should be evaluated in order to decrease their incidence as well as to maintain an intensive control of the arterial pressure during and after the procedure. This case is the first one published after angioplasty of a tandem lesion. It is possible that the pathophysiologic mechanism involved was an excessively rapid restitution of the normal arterial size.
