Hypertension After Carotid Endarterectomy. A hypotensive response group I affected 28 patients in whom mean arterial pressure decreased from 168 - 2990 - 15 mm Hg before operation to 110 - 2168 - 16 mm Hg after operation P less. Postoperative changes in blood pressure regulation were studied retrospectively in 56 patients and prospectively in 46 patients after carotid endarterectomy. Too much body weight puts a strain on the. 8 69 This is most likely related to transection or local anaesthetic block of the carotid sinus nerve during eversion endarterectomy which is associated.
70 Although this is a temporary phenomenon and persistence of hypertension is quite rare an increase in blood pressure and its variability 12 weeks after surgery has recently been demonstrated and characterized as baroreflex failure syndrome. Hypertension HT after carotid endarterectomy CEA is a risk factor for postoperative myocardial infarction stroke and neck hematoma. Postoperative changes in blood pressure regulation were studied retrospectively in 56 patients and prospectively in 46 patients after carotid endarterectomy. Carotid baroreceptor stimulation after CEA may cause hypotension. Restenosis after carotid artery stenting and endarterectomy. Carotid endarterectomy caused a significant acute elevation in blood pressure accompanied by little change in heart rate indicating baroreflex dysfunction.
Cerebral hyperperfusion syndrome is a preventable cause of stroke after carotid endarterectomy CEA.
Management of Post-Carotid Endarterectomy Hypertension 1 THEATRE RECOVERY. Page 3 of 5 Discharge Instructions. Arterial pressure regulation is often labile following carotid endarterectomy. Eversion CEA is associated with more postoperative hypertension greater use of vasodilators and less use of vasopressors after the operation than the standard longitudinal endarterectomy with or without patch angioplasty. Removal of the carotid plaque causes the carotid bulb to transmit increased arterial pulsation to the carotid sinus nerve. It manifests as headache seizures hemiparesis or coma due to raised intracranial pressure or intracerebral haemorrhage ICH.
