Mikel, a 60-year-old full-time worker and caregiver in Pamplona, experienced a sudden stroke while having lunch at Plaza del Castillo. Swift emergency intervention at the Hospital Universitario de Navarra demonstrated how acute stroke protocols operate against strict time limits, highlighting both the efficacy of rapid hospital triage and the severe reality of vascular disease.
In Plain English: The Clinical Takeaway
Stroke: A medical emergency where a blood clot blocks an artery supplying blood to the brain, starving neurons of oxygen and nutrients.
Thrombolysis and Thrombectomy: First-line pharmacological treatment dissolves clots using medication, while mechanical thrombectomy uses a catheter inserted via the groin to physically retrieve the blockage.
Secondary Prevention: Identifying underlying vascular risks—such as arrhythmias, hypertension, and atherosclerosis—prevents subsequent neurological events.
Emergency Response and Acute Triage at the Hospital Universitario de Navarra
Following a 112 emergency call placed by his companion, an ambulance reached Mikel in seven minutes. Transferred to the Hospital Universitario de Navarra, he arrived within twenty minutes. Emergency teams moved him to scanning just twelve minutes post-arrival, revealing an occlusion in the right middle cerebral artery.
Beatriz Zandio Amorena, a neurology specialist at the hospital, detailed the clinical pathway using this case as an example, based on a previously performed simulation. Clinicians administered thrombolytic therapy to break down the intravascular obstruction. Because the blockage required further intervention, specialists performed a mechanical thrombectomy, navigating a catheter through an artery in the groin to extract the thrombus directly.
Post-Acute Care and Identification of Underlying Vascular Pathology
Following the procedure, Mikel was transferred to the hospital’s Stroke Unit. Monitoring revealed behavioral changes, including apathy and reduced spontaneous speech. Diagnostic workup identified an intermittent cardiac arrhythmia predisposing him to the formation of clots, alongside atherosclerotic plaques, hypertension, elevated cholesterol, and prediabetes.
After 24 to 48 hours, clinical stability allowed transfer to a standard hospital ward, supported by magnetic resonance imaging to evaluate damage. Upon discharge, multi-disciplinary care transitioned to outpatient neurorehabilitation facilities at Ubarmin, occupational therapy, and neuropsychiatric support coordinated by primary care physicians and neurologists.
When to Consult a Doctor
Delaying evaluation diminishes the window of viable neuronal tissue salvage.
| Clinical Phase | Intervention / Action | Primary Objective |
|---|---|---|
| Pre-Hospital | Emergency dispatch (112) and transit | Minimize time-to-hospital arrival |
| Acute Assessment | Imaging & thrombolysis | Identify occlusion and dissolve thrombus |
| Intervention | Mechanical thrombectomy | Physically extract resistant clots via catheter |
| Rehabilitation | Neurorehabilitation and risk management | Restore functional independence and prevent recurrence |
Public Health Impact and Preventive Strategies
Irati del Valle de Lersundi Campistegui, a neurology nurse in the stroke unit, noted that the stroke represents the second leading cause of mortality in the State, the first among women, and one of the main causes of permanent disability and dementia. While incidence increases with age, it affects more young people.
Clinical consensus emphasizes primary prevention through controlling blood pressure, stopping smoking, maintaining a healthy diet, practicing exercise, and following prescribed treatments. Reducing baseline cardiovascular risk remains the most effective defense against permanent neurological impairment.
