Abstract:
Objective:To explore the mechanism of the embolism and sclerotherapy of fibrin glue combined with bleomycin (FG/BLM) for the treatment of cervicofacial vascular malformations by color doppler ultrasound.Methods:10 patients with venous malformation(VM) and 10 patients with arterio-venous malformation(AVM) were included.All patients underwent embolism and sclerotherapy of FG/BLM guided by ultrasound.Color doppler ultrasound was used to record the real-time two-dimensional ultrasonography and color doppler image.The flow and distribution of FG/BLM after injection into the lesions were observed.Results:Two-dimensional ultrasonography showed clumps or flake strong echo after immediate injection of FG/BLM into the cavity of VMs,then floated in the abnormal venous lumen and diffused throughout the cavity.At the later stage the lesions were filled by a large number of flocculent and netted low echo,and patchy strong echo.The volume of VMs cavity expanded dramaticlly,and the blood flow signal was significantly decreased.After injection of FG/BLM into the lumen of AVMs,clumps or flake strong echo were observed,then most of the snowflake strong echo rapidly filled or scattered along with blood stream to the distal part of the vessels.The color doppler showed significantly decrease of blood flow signal.Conclusion:FG/BLM injection can embolize and block the draining vein of VM,and play a role on the storage of sclerozing agent.FG/BLM injection can embolize both the dilated blood vessels and capillary network of AVM.
