RESUMO
A 44-year-old woman presented with recurrent episodes of thunderclap headache. Neurological examination and computed tomography brain imaging were unremarkable. Cerebrospinal fluid findings were consistent with subarachnoid hemorrhage. Computed tomography angiography of the circle of Willis showed multiple areas of segmental vasoconstriction. This finding was confirmed on cerebral catheter angiography, with segmental vasoconstriction involving bilateral internal carotid, posterior cerebral, and external carotid branches. No aneurysm or other vascular abnormality was identified. She received treatment with nimodipine. A selective serotonin reuptake inhibitor, started 4 weeks earlier, was discontinued. Follow-up angiography after 3 months demonstrated complete resolution of the segmental vasoconstriction, confirming the diagnosis of reversible cerebral vasoconstriction syndrome (RCVS). She remained headache free at follow-up. To our knowledge, external carotid artery branch involvement in RCVS has been described only in one previous occasion.
RESUMO
The role of neurointerventional treatment, including local thrombolysis, for intracranial venous thrombosis (ICVT) currently remains uncertain. We describe a case of postpartum ICVT involving the straight sinus, with rapid neurological deterioration and progressive thrombosis, despite anticoagulation. She underwent multimodality neurointerventional treatment involving attempted mechanical clot disruption, microcatheter suction, intrathrombus thrombolysis and microballoon disruption and clot retrieval. The patient achieved a full clinical recovery, with radiological evidence of recanalisation at follow-up.
