Insights
This case study highlights a successful intervention for acute cerebral infarction during cardiac catheterization. Prompt thrombolytic therapy significantly improved patient outcomes, demonstrating its critical role in managing procedural strokes.
Area of Science:
- Cardiology
- Neurology
- Interventional Radiology
Background:
- Percutaneous coronary catheterization, while diagnostic and therapeutic, carries a risk of stroke.
- Cerebral infarction following cardiac procedures can range from asymptomatic to severe, impacting patient prognosis.
Observation:
- A 61-year-old woman developed acute cerebral infarction with global aphasia, right hemiplegia, and left gaze preference during diagnostic cardiac catheterization for unstable angina.
- Immediate head CT revealed a hyperdense middle cerebral artery (MCA) sign, indicative of acute ischemic stroke.
Findings:
- Intravenous thrombolytic therapy was administered within 2 hours of symptom onset.
- The patient experienced a significant improvement, with the National Institutes of Health Stroke Scale score decreasing from 21 to 9 within 24 hours.
- Follow-up imaging confirmed resolution of the hyperdense MCA lesion.
Implications:
- This case underscores the critical importance of timely thrombolytic therapy for acute cerebral infarction occurring during cardiac catheterization.
- Early recognition and intervention can lead to favorable neurological outcomes and reduce stroke-related morbidity.
- Highlights the clinical benefit of thrombolysis in procedural strokes associated with cardiac interventions.
Abstract:
Diagnostic and interventional percutaneous coronary catheterization is associated with stroke. Many of such strokes are asymptomatic, but some are devastating. Once the diagnosis of acute cerebral infarction is confirmed, thrombolytic therapy should be administrated within the time window of 3 hours. We report a 61-year-old woman who suffered from an acute cerebral infarction during diagnostic cardiac catheterization for unstable angina, which manifested as sudden onset of global aphasia, right hemiplegia and gaze preponderance to the left side. Computed tomography of the head performed immediately after recognition of the symptoms showed a hyperdense middle cerebral artery (MCA) sign. Following prompt recognition and diagnosis, intravenous thrombolytic therapy was administered 2 hours after symptom onset. The patient had a favorable outcome. Initially, National Institutes of Health Stroke Scale score was 21, and 24 hours later it improved to 9. The hyperdense MCA lesion had resolved on the 24-hour follow-up scan. This case illustrates the clinical benefit of thrombolytic therapy in the setting of acute stroke associated with cardiac catheterization.
