Endovascular treatment for traumatic scalp arteriovenous fistulas: results with Onyx embolization

Abstract: Our experience in this small series indicates that endovascular treatment of S-AVFs with Onyx is rapid, safe, and highly effective.

“…[12][13][14][15] Although percutaneous use of Onyx has been reported in rare case reports involving the head and dural sinus, the technique of Onyx DSE of extremity AVMs has not been extensively discussed and reported in the English literature. [15][16][17][18][19][20] This limited use can be due to the need for dimethyl sulfoxide (DMSO) compatibility of the delivery apparatus and concerns for skin staining and ulceration with more superficial AVMs. DMSO is a chemical solvent that prevents premature polymerization of Onyx within the delivery apparatus before contact with ionic blood.…”

“…This point may be accessed transarterially or directly through the scalp under fluoroscopic guidance in order to deliver the embolization material. In cases where tortuosity of the feeding vessels limit access to the fistulous point, direct puncture embolization is a safe and effective alternative [5,10]. We opted for this route and used an inverted plastic cup to apply circumferential pressure to the scalp in order to impede both arterial inflow and venous drainage while the AVF was slowly filled with NBCA glue.…”

“…This may occur following a variety of insults, including: Car accidents, diving accidents, penetrating injuries from assaults with sharp objects, and iatrogenic etiologies, such as temporomandibular joint arthroscopy and punch-graft hair transplantation [1]. The literature related to scalp AVF following hair transplantation is limited primarily to single case reports [2][3][4][5][6][7][8][9][10][11][12][13][14]. These lesions have been successfully treated with surgical ligation, excision, direct puncture embolization, and selective angiography and embolization with full resolution in 100% of cases and no reported complications to this date.…”

“…[2][3][4][5] Recent reports describe the treatment of scalp AVM with nonadhesive liquid embolic agent such as Onyx (Covidien/Medtronics, Irvine, California, United States). [6][7][8][9] The existing literature pertains to transarterial as well as percutaneous embolization of scalp AVM. The data on percutaneous approaches are limited, and there are no reports as yet on the use of the new liquid embolic agent, SQUID (Emboflu, Switzerland) in the treatment of scalp AVM.…”
