  • Title: Intracranial Aneurysms After Intravenous Thrombolysis in Patient with Atrial Myxoma: A Case Study.
    Author: Li Z, Xu X, Hu L, Sun H, Yue Y.
    Journal: J Stroke Cerebrovasc Dis; 2020 Jun; 29(6):104796. PubMed ID: 32220555.
    Abstract:
    We administered intravenous thrombolytic therapy to a 51-year-old female patient with a 101-min stroke onset. The patient was unconscious during the manifestation of symptoms. Computed tomography angiography examination of the intracranial artery at the time of admission suggested that the left middle cerebral artery was occluded. The patient regained consciousness after the intravenous thrombolytic treatment was administered. On an urgent cerebral angiography, it was revealed that the recanalization of the left middle cerebral artery was successful. Although blood perfusion was restored, occlusion of the distal blood flow remained. The symptoms of the patient gradually improved after the treatment. However, 6 months after the onset of the condition, intracranial aneurysms formed distal to the recanalized arteries that were previously embolized. The full process underlying the development of cerebral embolism caused by atrial myxomas and subsequent formation of aneurysms is illustrated in this patient. Although the underlying mechanism remains unclear, intravenous thrombolysis can successfully restore cerebral blood flow in and may improve the prognosis of patients with cerebral embolism caused by cardiac myxoma. Despite the positive revascularization therapy, the occurrence of the complication of intracranial aneurysms is possible. Long-term follow-up to evaluate the progression of myxomatous aneurysms after cerebral embolism with conservative treatment may be a suitable strategy for managing such patients.
