Conclusion Patients with symptomatic arterial stenosis benefits from revascularizadores procedures, but also face a high risk of complications such as hyperperfusion syndrome rare, but serious. Cite this article Farooq, M. Finally, Dr. One should be cautious when selecting a drug for blood pressure control in these patients as some of the anti-hypertensives with vasodilatory effects may worsen the outcome. Although originally described after carotid endarterectomy, it has now also been described after carotid artery stenting. Bernstein and colleagues described a year-old man with a high-grade left carotid stenosis who had left CEA [ 8 ]. The pathophysiology of reperfusion related injury is not entirely clear, however, it is believed that dysregulation of the cerebral vascular system and hypertension resulting in an increase of CBF play a significant role. It may be prudent to carefully monitor blood pressure in patients with increased CBF as hypertension may subsequently develop postoperatively even in normotensive patients. On the second postoperative day he had grand mal seizures. Regulation of blood-brain barrier endothelial cells by nitric oxide.

    Using TCD, patients with low preoperative cerebrovascular reserve are at risk of developing cerebral hyperperfusion and CHS [ 182324 ]. If these patients are treated early, they may do better as there may be minimal complications and a good recovery.

    In general, patients with severe carotid artery stenosis often have underlying systemic hypertension and undergo CEA to reduce the risk of stroke in a vascular bed that may be subject to chronic cerebral ischemia. Therefore, one should be careful when selecting an anesthetic and its dose as high doses of a volatile halogenated hydrocarbon anesthetic may lead to the development of CHS.

    If these patients are treated early, they may do better as there may be minimal complications and a good recovery. Blood pressure in patients with CHS should be controlled with either labetalol or clonidine, which do not increase CBF [ 231921 ].

    Medications in the latter group include calcium channel blockers, sodium nitroprusside, glycerol trinitrate, and angiotensin II inhibitors. The patient developed a severe left-sided headache on the first postoperative day.

    It has been shown that oxygen-derived free radicals associated with CEA play a role in furthering ischemic injury even after short-term carotid artery clamping [ 1415 ]. Damaging the BBB allows extravasation of toxins and edema into the brain parenchyma.
