Summary
Delayed diagnosis of traumatic carotid artery dissection can lead to permanent neurological deficits. Early detection through clinical suspicion and imaging is crucial for better patient outcomes.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Traumatic carotid artery dissection (TCAD) poses significant risks, including permanent neurological deficits and high mortality rates up to 40% if not diagnosed and treated promptly.
- Early diagnosis and intervention are critical for mitigating severe consequences.
Observation:
- A case of delayed diagnosis of TCAD in a 21-year-old female is presented.
- Initial cerebral computerized tomography (CT) showed no ischemic infarcts, but findings emerged seven days later, coinciding with the patient regaining consciousness and exhibiting left hemiplegia.
- Diagnosis was confirmed using arterial Doppler ultrasonography, cerebral magnetic resonance imaging (MRI), diffusion MRI, and MR angiography.
Findings:
- The patient presented with delayed diagnosis of traumatic carotid artery dissection.
- Ischemic infarcts were detected on follow-up cerebral CT scans after initial negative findings.
- Grade IV dissection was identified, and invasive treatment was deemed unsuitable due to permanent neurological damage.
Implications:
- This case highlights the challenge of missed or delayed diagnoses in traumatic carotid artery dissection, even with advanced imaging techniques.
- Emphasizes the importance of high clinical suspicion, thorough physical examination, and appropriate radiological investigations for early detection.
- Prompt diagnosis is essential to ameliorate or prevent permanent neurological damage in patients with traumatic carotid artery dissection.

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...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:29Stroke: Introduction and Types
A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
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...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
