Dr. Theodotou studies complications that arise from specific surgical procedures, mainly carotid endarterectomy, which helps clear blocked arteries in the neck to improve blood flow to the brain. He examines both the risks and outcomes of these surgeries, documenting adverse effects such as nerve injuries and overall patient health post-operation. Additionally, he investigates diagnostic techniques for infections in the spinal area, which can lead to serious health concerns if not identified and treated promptly. His research informs surgeons and patients about potential complications, allowing for more informed decisions regarding surgical interventions.
Key findings
In a study of 192 carotid endarterectomy operations, the mortality rate was only 0.5%, indicating a relatively safe procedure.
The incidence of nerve injuries during carotid endarterectomy was 4.7%, with some injuries showing no improvement over two years, underscoring the need for careful surgical techniques.
The use of metrizamide spinal computed tomography effectively identified spinal subdural empyema in a diabetic patient, demonstrating its role in diagnosing infections.
Frequently asked questions
Does Dr. Theodotou study carotid endarterectomy?
Yes, he focuses on the complications that can arise from carotid endarterectomy surgeries, including stroke and nerve injuries.
What types of complications does he look at?
He examines surgical risks such as nerve injuries, patient mortality, and overall recovery outcomes following carotid endarterectomy.
Is his research relevant for patients with spinal infections?
Yes, he studies diagnostic methods for spinal infections, which helps improve treatment options for patients affected by these conditions.

Stroke
Theodotou B, Mahaley MS
Plain English This study looked at nerve injuries that happen during a specific type of surgery called carotid endarterectomy, which helps improve blood flow in the neck. Out of 192 surgeries, 4.7% resulted in nerve injuries, including two affecting the facial nerve, five the hypoglossal nerve, and two the vagus nerve. Importantly, the facial nerve injuries did not improve over two years, highlighting the need for careful surgical techniques to reduce these risks.
Who this helps: This helps patients undergoing carotid endarterectomy.

Surgical neurology
Theodotou B, Mahaley MS
Plain English This study looked at the complications that occurred after carotid endarterectomy surgeries in 162 patients. Out of 192 operations, there was a very low mortality rate of just 0.5%, and complications like stroke and heart attack were evaluated by the type of symptoms patients had before surgery. Understanding these complications helps doctors better assess risks for different groups of patients, leading to improved treatment outcomes.

Surgical neurology
Theodotou B, Woosley RE, Whaley RA
Plain English The study looked at how a special type of CT scan, called metrizamide spinal computed tomography, is used to identify spinal subdural empyema, which is an infection that occurs in the spinal area. In this case, they successfully applied the scan to a 65-year-old woman with diabetes. This research is important because it helps doctors understand the extent of the infection, allowing for better treatment decisions.
Who this helps: This benefits doctors and patients with spinal infections.
