Brain arteriovenous malformation treatment with transvenous endovascular technique after transarterial technique failure

Arteriovenous malformations (AVMs) are unnatural connections in the vascular system. The treatment strategies are dictated by the angioarchitecture, location and presentation of AVMs. The present study sought to report a case report of a 35-year-old female patient diagnosed with a brain AVM and submitted to a transvenous AVM embolization, located at the corpus callosum's splenium, after a previous transarterial embolization failure. As a therapeutic approach, the patient was submitted to transarterial embolization. However, the procedure was performed too proximally in the arteries, which resulted in the total AVM persistency. The patient was submitted to angiographic control until complete AVM occlusion.

Background and objective One of the treatment options for arteriovenous malformations consists of embolization, with a choice of various embolic agents, with or without subsequent surgical excision. If embolization is offered without subsequent surgery, the embolic material will stay in situ, in which case the consistency and color become important in superficial lesions. The purpose of this case report is to describe if the use of a novel liquid embolic agent (PHIL) is well suited for treatment of superficial AVMs without subsequent surgery. Case description A 30-year-old male presented with a painful reddish, pulsatile swelling of the left ear that had been present for more than 10 years. Angiography confirmed an arteriovenous malformation supplied by the superficial temporal artery and the posterior auricular artery. The lesion was successfully treated by embolization with PHIL, through the superficial temporal artery. A minute residual shunt, from the posterior auricular artery, was accepted. Immediate disappearance of pulsatile tinnitus was reported. Moreover, return of normal skin color was observed without discomfort from the embolic deposits. This result has been stable throughout one year of clinical follow-up. Conclusion To our knowledge, this is the first case report describing PHIL embolization as a treatment option for superficial arteriovenous malformations without the necessity for subsequent surgery. The white color and rubbery consistency are beneficial characteristics of PHIL in treatment of subcutaneous lesions, especially in cosmetically relevant locations.

And Tungsten

Prediction of nidal penetration of the glue is difficult in the embolisation of brain arteriovenous malformations (AVM). We evaluated penetration differences of glue-lipiodol mixtures with and without tungsten powder for embolisation of brain AVM. Fifty eight injections during embolisation of brain AVM in 15 patients were evaluated. Glue contained lipiodol only (N=25), or lipiodol and tungsten powder (N=33). Glue concentration ranged from 20 to 80%. Injection was done at the pedicle (N=41) or nidus (N=17). Degree of penetration was rated as good, fair, or poor according to penetrated glue amount in the nidus. Penetration difference was compared in each injection at the pedicle or nidus. When the glue mixtures were injected at the pedicle, the glue-lipiodol mixture (GLM) penetrated into the nidus in eight of 16 injections (50%) and the glue-lipiodol-tungsten mixtures (GLTM) in 23 of 25 (92%). When glue was injected at the nidus, GLM was confined to the nidus in nine of nine injections (100%) and GLTM in seven of eight (88%). Penetration into the vein was noted in two of 25 injections (8%) in GLM and six of 33 (18%) in GLTM. Penetration difference into the nidus between GLM and GLTM was statistically significant (p < 0.05) when the glue mixtures were injected at the pedicle. GLM and GLTM can be used effectively at the nidus. In contrast to GLM, GLTM can be used effectively at the pedicle. However, the risk of venous penetration seemed to be higher with GLTM than in GLM.

Perimedullary spinal AVM is a rare type of spinal arteriovenous malformations. We present a case of 70 yrs female who presented with motor weakness in her bilateral limbs. Initial MRI was misinterpreted as ependymal myxoma; however, histopathology revealed spinal AVM. MRA or DSA should be conducted if AVM is suspected.
