Reversible change of early venous filling after emergency endovascular therapy: a case report / 中华神经科杂志

ABSTRACT

Early venous filling is a special imaging manifestation of cerebral angiography in patients with acute ischemic stroke. Endovascular therapy for acute ischemic stroke has been carried outwidely. However, reports involving disappearance of early venous filling and then confirming its reversibility during follow-up angiographic review are somewhat scarce. Here a case in which the early venous filling after emergency thrombectomy disappeared during follow-up examination is reported. A 71-year-old male was admitted with sudden onset of left-sided weakness for 42 minutes. Intravenous thrombolysis and bridging middle cerebral artery mechanical thrombectomy were performed. Early filling of the thalamostriate vein was visible in the digital subtraction angiography series immediately after recanalization and follow-up imaging revealed infarction of the basal ganglia. Follow up angiography showed that the phenomenon of early venous filling disappeared two weeks later.
