Hypertension is associated with hyperperfusion syndrome after which procedure?

Hypertension is associated with hyperperfusion syndrome particularly after carotid endarterectomy. This surgical procedure involves the removal of plaque from the carotid artery to improve blood flow to the brain and reduce the risk of stroke. Following carotid endarterectomy, patients may experience a sudden increase in blood flow to the already perfused brain tissue, especially if there was previously compromised blood flow due to significant arterial stenosis.

In patients with chronic carotid artery occlusion, the brain may have adapted to a reduced blood supply, and any sudden restoration of blood flow can lead to hyperperfusion. This phenomenon can result in symptoms such as headache, neurological deficits, and even intracerebral hemorrhage, driven by the sudden increase in perfusion pressures in the brain.

Other options relate to different contexts where hypertension may or may not be a factor in hyperperfusion. For instance, while hypertension can be consequential in stroke patients, the direct linkage with hyperperfusion syndrome is most specifically related to the post-operative state following carotid endarterectomy.
