Treatment of acute hemorrhagic high-flow cerebral vascular malformations using a hybrid surgical platform
Objective To initially explore the safety and effectiveness of a one-staged hybrid surgical platform in the treatment of acute hemorrhagic high-flow cerebral vascular malformations(HFVMs).Methods Patients with acute hemorrhagic HFVMs who were consecutively enrolled from January 2019 to April 2024 were screened from a prospective,multi-center surgical cohort of hybrid surgical treatment of cerebral vascular malformations(NCT03209804).All patients underwent diagnostic intraoperative digital subtraction angiography(DSA)and different modes of surgical treatment on a hybrid surgical platform.The patients'functional outcomes(assessed by the modified Rankin scale score)were analyzed to clarify the safety and effectiveness of the hybrid surgical platform in the treatment of acute hemorrhagic HFVMs.Results A total of 56 patients with acute hemorrhagic HFVMs were included,including 47 patients(83.9%)with intracranial arteriovenous malformation rupture and bleeding,8 patients(14.3%)with dural arteriovenous fistula,and 1 patient(1.8%)with pial arteriovenous fistula.Among the 56 patients,33 patients underwent arteriovenous malformation or arteriovenous fistula resection plus hematoma evacuation,15 patients underwent endovascular embolization-assisted arteriovenous malformation or arteriovenous fistula resection plus hematoma evacuation,6 patients underwent curative embolization of arteriovenous malformation or arteriovenous fistula,and 2 cases were treated with curative embolization of arteriovenous malformation or arteriovenous fistula plus minimally invasive hematoma evacuation.The all-cause mortality rate of patients within 1 month after surgery was 3.6%(2/56).The rates of patients with severe neurological dysfunction(modified Rankin score>3 points)at discharge,3 months after surgery,and 6 months after surgery were 46.4%(26/56),16.1%(9/56),and 8.9%(5/56),respectively.Conclusion The one-staged diagnosis and treatment model based on the hybrid surgical platform can be safely and effectively used to treat acute hemorrhagic HFVMs.
