Scalp arteriovenous fistulas (AVFs) with multiple tortuous superficial feeders and a large venous pouch can require meticulous flow control during treatment. Open surgical excision may be associated with blood loss, wound-healing problems, and cosmetic concerns, whereas percutaneous liquid embolization of a high-flow superficial shunt carries a risk of nontarget migration and scalp necrosis....

No actionable change for audiologists — this is a neurovascular/interventional radiology case report with no direct relevance to audiology clinical practice.
While scalp arteriovenous fistulas can theoretically cause pulsatile tinnitus, this single case report of an incisionless percutaneous technique has no direct bearing on audiology practice and is outside the field's scope.
- 01Case report of a single patient with a high-flow scalp arteriovenous fistula (abnormal artery-vein connection) and large venous pouch.
- 02Treatment used a stepwise, incisionless percutaneous (through-skin) flow-control approach.
- 03No surgical incision was required, distinguishing this from conventional open surgical repair.
- 04Findings are limited to one case and cannot be generalised.
- 05Relevance to audiology is peripheral at best (pulsatile tinnitus differential).
A stepwise incisionless percutaneous approach can successfully treat a high-flow scalp arteriovenous fistula with a large superficial venous pouch.
