Summary
Postoperative seizures are a rare complication following carotid revascularization procedures like carotid endarterectomy. This study highlights that seizures can also occur after innominate artery surgery, expanding the understanding of this neurological complication.
Area of Science:
- Neurology
- Vascular Surgery
- Neurosurgery
Background:
- Seizures post-carotid revascularization are an uncommon but recognized complication.
- Estimated incidence of postoperative seizures after carotid endarterectomy ranges from 0.4% to 1.0%.
- High-grade carotid artery stenoses are associated with the highest risk, potentially due to cortical hyperperfusion.
Observation:
- This report details two cases of focal motor seizures.
- These seizures occurred following innominate endarterectomy.
Findings:
- Postoperative seizures are not exclusive to carotid artery surgery.
- Innominate endarterectomy can also precipitate seizures.
Implications:
- The findings suggest a broader spectrum of cerebrovascular surgery associated with postoperative seizures.
- Clinical vigilance for seizures should extend to patients undergoing innominate artery revascularization.
- Further research may elucidate shared pathophysiological mechanisms between carotid and innominate revascularization-associated seizures.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
