Abstract:
Although in the treatment of extracranial vascular malformations the absolute ethanol used as an embolization agent has several advantages(such as low cost,reliable efficacy,no impact on subsequent treatments,etc.)and has already achieved significant progress in clinical practice,it is still regarded as a highly-selective liquid embolization agent in the sclerotherapy or embolization treatment of brain arteriovenous malformation(bAVM).At present,the indications of sclerotherapy and embolization therapy by using absolute ethanol include small AVM(＜3 cm)located at brain cortex or at non-eloguent area,and relatively low-flow AVM,in such case,the absolute ethanol acts as an effective supplement to other liquid embolization agents.Further studies are needed so as to improve the radiographic visualization and viscosity of absolute ethanol,to make the injection process more controlled,and to alleviate the edema caused by neurotoxicity and inflammation.
