Value of direct percutaneous puncture in the AMV treatment

SUMMARY:

Purpose: We present our experience in four cases using embolization technic by percutaneous direct puncture and injection of n-Butyl-2 Cyanoacrylate to embolize high flow fistula arteriovenous malformations having multiple feeding arteries.

Materials and methods: 3 patients with high flow arteriovenous malformations (AVMs) of the head, neck region and one patient’s AVM in arm were treated with direct percutaneous injections of Histoacryl.

Results: There were no major complications after the embolization procedure. The arteriovenous shunts were completely eliminated in three cases. The embolization was incomplete in one patient who required a surgical procedure to remove the residual AVM lesion and also for esthetic reason.

Conclusion: Embolization by percutaneous direct puncture with n-BCA injection appears to be a good treatment for the high flow arteriovenous malformations having multiple feeding arteries and large nidus.
