Abstract
RATIONALE: Stroke is a relatively frequent complication occurring in patients with systemic lupus erythematosus (SLE). The increasing number of patients with Ischemic Stroke secondary to SLE aroused the clinician's concern. SLE thrombosis markers, diagnostic high-resolution magnetic resonance image (HR-MRI), and therapeutic interventions for acute ischemic stroke were recently coming into focus perspectives from the field. PATIENT CONCERNS: A 42-year-old female with slurred speech and numbness in her left limb was admitted to our hospital. DIAGNOSES: Magnetic resonance imaging (MRI) revealed right thalamic infarction with diffusion-weighted lesions. Prior to admission, the patient had a National Institute of Health Stroke Scale (NIHSS) score of 3. INTERVENTIONS: In light of the clinical manifestation, the American Heart Association/American Stroke Association (AHA/ASA) Guidelines for Intravenous Thrombolysis in Acute Ischemic Stroke (2019) should be referred to. The patient was treated with thrombolytic alteplase (rt-PA). OUTCOMES: The patient was hospitalized for 2 weeks and discharged after his symptoms improved. LESSONS: After thrombolysis, the NIHSS score of the patient decreased to zero. The computed tomography scan was reexamined 24 hours later, and no acute changes or hemorrhage were identified in the infarcted area. Subsequent imaging and serological analyses indicated that HR-MRI of the responsible vessel was negative, but the infarction in this patient was still regarded as being caused by vasculitis of the right posterior cerebral artery in the region supplying the thalamus. This is the first case of successful intravenous thrombolytic therapy with rt-PA in a patient with SLE secondary to stroke with an NIHSS score of 3. This provides further evidence for expanding the reference of indications with rt-PA intravenous thrombolysis.
