Direct percutaneous puncture embolization of type II endoleaks using a coaxial technique.

To demonstrate a coaxial needle technique for direct percutaneous puncture embolization of type II endoleaks.
The technique is demonstrated in a 79-year-old woman and an 80-year-old man who developed type II endoleaks after endovascular repair of thoracic and internal iliac artery aneurysms, respectively. Expansion of the aneurysms required additional therapy. Fluoroscopy and cone-beam computed tomography-guided direct percutaneous endoleak sac embolization with n-butyl-2-cyanoacrylate (NBCA)-lipiodol was performed using the coaxial technique, which resulted in complete embolization of the endoleak sac. At 6 and 3 months after embolotherapy, respectively, the NBCA-lipiodol filled the endoleak sacs and the communicating channels up to the respective feeding arteries; no enlargement of the aneurysms was observed.
Direct percutaneous sac embolization using a coaxial technique for type II endoleaks is a feasible treatment and yields good short-term results. More experience with this technique and longer follow-up of these patients is needed.
