“…The process often produces degenerative weakening within the wall of these vessels, predisposing to rupture. Although the natural history of sporadic cerebral AVM has been well documented, the specific natural course of the cerebral AVM in HHT is not known 23 .…”

“…They form a part of syndromes such as Rendu-Osler-Weber or Klippel-Trenaunay-Weber syndrome, consistent with the fact that a genetic abnormality contributes to their etiology. 5,13,18 Acquired pial AVFs are very rare and are the result of traumatic injury or iatrogenic causes. Our patient had a minor head injury, but it was difficult to identify whether this head injury was the cause of the pial AVF from her initial CT scan.…”

Intracranial pial arteriovenous fistulas (AVFs) are rare cerebrovascular lesions. The authors report a rare case of pediatric pial AVF treated by direct disconnection with the aid of indocyanine green (ICG) videoangiography. A 3-year-old girl presented with developmental problems. Magnetic resonance imaging revealed brain atrophy and an anomalous left temporal vascular mass. Angiography showed a high-flow pial AVF in the early arterial phase fed by the M1 portion of the left middle cerebral artery and draining into the superficial sylvian vein and the vein of Trolard with a large varix. Given that her fistula was located in a superficial region that was easily accessible by craniotomy, the authors successfully disconnected her pial AVF by direct surgery aided by ICG videoangiography, which clearly confirmed the shunting point. In this report, the authors discuss the existing literature and compare the relative merits of endovascular versus surgical options for the treatment of pial AVF.

“…Intracranial pial AVFs are composed of one or more direct arterial shunt to a sole venous channel without abnormal interconnecting nidus, which differentiate from AVMs for the absence of nidus and dural AVFs for the feeding vessels originated from pial or cortical arteries and located outside of the dural leaflets (4,12). The high and turbulent blood flow hemodynamics of pial AVFs result from arteriovenous shunt from feeding arteries directly into single draining vein, which result in venous dilatation, varix and even the aneurysm of the feeding artery (8,10).…”

Intracranial pial arteriovenous fistulas (AVFs) associated with multiple aneurysms of the main feeding arteries are very rare cerebrovascular lesions. We report a unique case of pial AVFs associated with four aneurysms of the feeding anterior cerebral artery (ACA) which presented as intracerebral hemorrhage (ICH), intraventricular hemorrhage (IVH) and spontaneous subarachnoid hemorrhage (SAH). CT angiography (CTA) and digital subtraction angiography (DSA) images demonstrated clearly the direct connection without nidus between the first and second segment of right ACA accompanied by four irregular aneurysms and an abnormally dilated draining vein into the superior sagittal sinus (SSS). Owing to the superficial-seated fistulas, the morphology of feeding arteries and associated four aneurysms and intracranial hemorrhage, the lesions were surgically treated. Postoperative cerebral angiography certified closure of the fistulas and exclusion of the four aneurysms as well as disappearance of early venous drainage. However, subsequent precontrast brain CT showed hydrocephalus underwent left ventriculoperitoneal shunt placement.KEywoRds: Pial arteriovenous fistula, Aneurysm, Cerebral hemorrhage, Angiography, Surgery ÖZ Ana besleyici arterlerin birden fazla anevrizması ile ilişkili intrakraniyal pial arteriyovenöz fistüller (AVF'ler) çok nadir serebrovasküler lezyonlardır. Burada intraserebral kanama (İSK), intraventriküler kanama (İVK) ve spontan subaraknoid kanama (SAK) olarak ortaya çıkan, anterior serebral arterin (ASA) dört anevrizması ile ilişkili benzersiz bir pial AVF olgusu bildiriyoruz. BT anjiyografi (BTA) ve dijital subtraksiyon anjiyografi (DSA) görüntüleri net bir şekilde dört düzensiz anevrizmanın eşlik ettiği, sağ ASA'nın birinci ve ikinci segmenti arasında nidus olmaksızın doğrudan bağlantıyı ve superior sagittal sinüs (SSS) içine anormal genişlemiş drenaj venini göstermiştir. Yüzeysel yerleşimli fistüller, besleyici arterler, ilgili dört anevrizma ve intrakraniyal kanama morfolojisi nedeniyle lezyonlar cerrahi olarak tedavi edildi. Postoperatif serebral anjiyografi hem fistüllerin kapatılması ve dört anevrizmanın eksklüzyonunu hem de erken venöz drenajın ortadan kaldırılmasını doğruladı. Ancak, sonraki prekontrast beyin BT hidrosefali gösterdi ve sola ventriküloperitoneal şant uygulandı.
