Hemorrhage On A Dependent Area Of Posterior Cerebral Circulation Due To Hyperperfusion Syndrome After Stenting In Internal Carotid Artery. Rev Ecuat Neurol [online]. 2023, vol.32, n.2, pp.111-113.

Cerebral hyperperfusion syndrome (CHS) after stent placement has a low incidence, between 0.37- 1.9%(1)(2). We present a case of CHS due to recanalization in right internal carotid artery (ICA) which, contrary to expectations, produces a hematoma on a dependent area of the posterior cerebral circulation. Through the clinical case, we proceed to delve into the CHS and the characteristics that give the patient a higher risk. In addition, we expose the potential usefulness of the neurosonological study of inter-individual variability for better perioperative management. In this way, we can ensure a good therapeutic approach that minimizes morbidity and mortality as much as possible.
