Endovascular Treatment of Renal Arteriovenous Fistula with N-Butyl Cyanoacrylate (NBCA)

چکیده
BACKGROUND Renal arteriovenous malformation (RAVM) is a rare disease. The causes of pathological connections between renal arteries may be congenital or iatrogenic - mainly as a consequence of a biopsy or due to renal carcinomas and postinflammatory changes. Computed tomography, ultrasound Doppler and angiography are the main diagnostic tools used for the detection of RAVMs. CASE REPORT The aim of this study is to present a case of endovascular treatment of RAVM with a mixture of NBCA and lipiodol. A 29-year-old woman was suffering from drug-resistant hypertension secondary to RAVM. The malformation was embolized using NBCA mixed with lipiodol. The postoperative course was uneventful. A follow-up angio-CT, performed 3 months and one year after the procedure, showed a complete occlusion of the RAVM. CONCLUSIONS NBCA can be used alone to embolize RAVMs. Procedures involving a combination of NBCA and lipiodol are difficult and should be performed by experienced specialists.

Successful treatment of acquired uterine arterial venous malformation using N-butyl-2-cyanoacrylate under balloon occlusion
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, ...

BACKGROUND AND PURPOSE Because they are not well established, we investigated the technical success and recurrence rates of n-butyl 2-cyanoacrylate (NBCA) embolization of spinal dural arteriovenous fistulae (SDAVF), and assessed clinical outcomes. METHODS We retrospectively studied all patients with SDAVF treated by NBCA embolization at our institution over an 8-year period. Gait and micturit...

We present a case with prenatal diagnosis of an intracranial high-flow pial arteriovenous fistula that was draining into the vein of Galen in the third trimester of pregnancy. The child was treated by transcatheter embolization with N-butyl 2-cyanoacrylate (NBCA) via the umbilical artery in the early neonatal period due to intractable cardiac failure. Hydrocephalus developed and a ventriculoper...

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...

We present a case of a ruptured vertebral artery dissecting aneurysm that mimicked a presumed vascular anomaly by CTA (Computerized Tomographic Angiography). A parenchymal arteriovenous malformation (AVM) or a dural arteriovenous fistula (DAVF) at the craniocervical junction can present with a subarachnoid hemorrhage and cannot be differentiated from a vertebral artery dissection by non invasiv...
