Balloon-assisted U-turn Technique to Access Cortical Vein for Transvenous Embolization of Mixed Dural-pial Arteriovenous Malformation

Interv Neuroradiol. 2024 Jan 15:15910199231226288. doi: 10.1177/15910199231226288. Online ahead of print.ABSTRACTCerebral arteriovenous malformations can be classified into pure pial, mixed dural-pial, and pure dural types. Mixed pial-dural AVMs (DPAVM) are rare and often receive blood supply from dural meningeal arteries, including branches of the internal carotid, external carotid, and vertebral arteries.1- 6 DPAVMs, which are usually large and complex, require delicate endovascular and surgical treatment methods. The cure rate is low, and recurrence is very common, leading to high morbidity and mortality. In this case video, we present a case of PDAVM that recurred after initial endovascular onyx embolization, requiring additional endovascular coiling which resulted in obliteration of the DPAVM.PMID:38225178 | DOI:10.1177/15910199231226288
