Successful treatment of acquired uterine arterial venous malformation using N-butyl-2-cyanoacrylate under balloon occlusion
نویسندگان
چکیده
We present two cases of acquired uterine arterial venous malformation (AVM) which was diagnosed because of massive genital bleeding successfully treated with transcatheter arterial embolization (TAE), using N-butyl-2-cyanoacrylate (NBCA) under balloon occlusion. Balloon occlusion at the uterine artery was performed in both patients for diffuse distribution of NBCA in multiple feeding branches, as well as to the pseudoaneurysm, and for the prevention of NBCA reflux. In one of our patients, balloon occlusion of the draining vein was simultaneously performed to prevent NBCA migration through accompanying high-flow arteriovenous fistula (AVF). Doppler ultrasound at 6 months of both patients documented persistent complete occlusion of AVM. Complete and safe obliteration of acquired uterine AVM was accomplished using NBCA as embolic agent, under balloon occlusion at the communicating vessels of acquired uterine AVM.

Onyx transarterial embolization of dural arteriovenous fistula for failed N-butyl cyanoacrylate treatment: case report
Total occlusion of dural arteriovenous fistulas (DAVFs) via transarterial embolization is difficult due to the rich anastomotic network of the dural/falcine plethora of feeding arteries, blood supply to cranial nerves, and extracranial to intracranial anastomoses. Incomplete occlusion of the fistulas will result in recanalization of the DAVF from the multiple collateral arteries constituting th...

Trauma patients with uncontrolled hemorrhage encountering coagulopathy are often associated with poor outcome. Recently, the concept of damage control interventional radiology, which focuses on "speedy stoppage of bleeding" by interventional radiology among trauma patients with hemodynamic instability and acute traumatic coagulopathy, was proposed as an alternative to damage control surgery. N-...
متن کاملDirect Puncture Embolization of a Recurrent Internal Iliac Artery Aneurysm with N-Butyl-2-Cyanoacrylate Under Flow-Control with Balloon
Background If only proximal embolization or ligation is performed for an internal iliac artery aneurysm (IIAA), transcatheter arterial embolization is sometimes difficult due to complex collateral circulation. A new method of direct percutaneous n-butyl-2-cyanoacrylate (NBCA) sac embolization (b-DNSE) under balloon arterial occlusion for re-intervention of an IIAA after proximal ligation is pre...

BACKGROUND AND PURPOSE The rete mirabile in swine has been proposed as an arteriovenous malformation (AVM) model for acute experimental studies through surgical creation of a large carotid-jugular fistula. This report describes two endovascular modifications to simplify the surgical creation and provides hemodynamic parameters for the AVM model. METHODS An AVM model was created in 29 animals ...
متن کاملTransarterial balloon-assisted n-butyl-2-cyanoacrylate embolization of direct carotid cavernous fistulas.
BACKGROUND AND PURPOSE Transarterial detachable balloon embolization of direct carotid cavernous fistulas (DCCFs) has become an optimal treatment. In a few cases, the parent artery has to be sacrificed to achieve morphologic cure. We present our experience with transarterial balloon-assisted n-butyl-2-cyanoacrylate (n-BCA) embolization of DCCFs in which there was failure to achieve angiographic...
