Skew deviation: a precursor to basilar artery thrombosis.
Clinical & Experimental Ophthalmology
|September 27, 2005
Summary
Skew deviation and vertical nystagmus can be early indicators of basilar artery thrombosis. Prompt diagnosis and intervention led to complete recovery in a patient presenting with these neuro-ophthalmological signs.
Area of Science:
- Neuroscience
- Ophthalmology
- Vascular Neurology
Background:
- Basilar artery thrombosis is a critical condition often presenting with diverse neurological deficits.
- Early recognition of specific signs is crucial for timely intervention and improved patient outcomes.
Observation:
- A 51-year-old woman presented with vertical diplopia, nausea, dyspnea, and somnolence.
- Initial brain CT was normal, but neuro-ophthalmological examination revealed skew deviation and vertical nystagmus.
Findings:
- Magnetic resonance imaging confirmed basilar artery occlusion.
- Emergency intra-arterial thrombolysis successfully recanalized the basilar artery.
- The patient experienced complete neurological recovery, including resolution of ocular motor abnormalities.
Implications:
- Skew deviation and vertical nystagmus can be key initial signs of basilar artery occlusion.
- This case underscores the importance of thorough neuro-ophthalmological assessment in diagnosing cerebrovascular emergencies.
- Prompt diagnosis and intervention are vital for favorable outcomes in basilar artery thrombosis.

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.

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
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...
01:17Hemorrhagic 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...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
