[Pharmaceutical therapy for the severe hemodynamic depression with carotid artery stenting]

To evaluate the efficacy of pharmaceutical therapy for the severe hemodynamic depression with carotid artery stenting(CAS).

Clinical data were retrospectively analyzed on CAS over the last 5 years. Severe hemodynamic depression was defined as periprocedural hypotension (blood pressure <90/60 mmHg) or bradycardia (heart rate <50 beats/min) persisting for at least 1 hour. 13 patients were included in the research.

Dopamine was pumped intravenously in all the 13 patients .The dose was from 2 microg/min/kg to 10 microg/min/kg, the duration was from 4 to 48 hours. Dobutamine was used in 2 patients and dose from 5 microg/min/kg to 7 microg/min/kg, duration was from 24 to 36 hours. None of the patients developed any permanent neurological complications. One acute coronary syndrome occured during the postprocedure period.

Severe hemodynamic depression can be controlled with vasopressors (dopamine or dobutamine) and the associated complications can be prevented.
