“…We reviewed the English-language literature using the words ‘pial fistula,’ ‘arteriovenous fistula’ and ‘non-Galenic fistula in infancy’ from 1980 until October 2017; we found 73 cases including the two cases reported in the present article (Table 1). 12–19 Twelve cases presented with cerebral haemorrhage, accounting for 16.4%, which is nearly similar to the same ratio of Weon and colleagues. 11 Fifteen single- and 20 multi-hole fistulae were identified.…”

Cerebral pial fistula is a rare vascular pathology with no more than 150 cases reported. Most cases reported in infancy have been published as case reports. Owing to its high flow, its occurrence in this age group carries the potential risk of heart failure, chronic venous hypertension, seizures and, less frequently, cerebral haemorrhage. We present two cases of pial fistulae in infancy treated by endovascular embolisation using N-butyl cyanoacrylate. A review of the English-language literature was performed for this age group with special emphasis on ruptured cases.

Background:Pial arteriovenous fistula (PAVF) is a rare vascular condition comprising of one or more arterial vessels that are in direct communication with the draining veins. The condition is also characterized by the absence of a nidus. Due to high blood flows, varicose systems adjacent to the fistula appear. The key characteristic of the arteriovenous direct transition is that it offers a treatment option in which interruption of the blood flow can occur without removing the entire lesion. This study presents two cases of PAVF.Case Description:The first case is of a 59-year-old male with lesions in the frontal region, fed by a branch of the right anterior cerebral artery and drained by the frontal basal vein to the sphenoparietal sinus. The second case is of a 3-year-old child with a lesion in the right anterior frontal lobe, fed by a branch of the right middle cerebral artery, which drains into the Trolard vein and was associated with large a venous varix.Conclusion:PAVF is a disease characterized by its rarity, and knowledge of PAVF's clinical presentation is of vital importance in early diagnosis. The treatment of the condition consists of an occlusion of the supply vessel, which can be done by endovascular, microsurgical, or both procedures. Both the cases were successfully treated by microsurgical procedure.

“…Moreover, several embolic materials such as coils, balloons, onyx, and glue can be used to disconnect the AVFs. [5][6][7][8][9][10][11] Detachable coils have some advantages with regard to the embolization of high-flow pial AVFs because they are controllable before detachment, and migration of embolic materials to the distal draining vein can be prevented.…”

“…2,4 Endovascular coil embolization has been reported to be an effective treatment for pial AVFs. [5][6][7][8][9][10][11] However, venous thrombosis and intracranial hemorrhage developing after endovascular occlusion of pial AVFs are rare but devastating complications that have not been adequately reported.…”

Background Endovascular coil embolization of pial arteriovenous fistulas (AVF) has been reported as an effective treatment. However, venous thrombosis and intracranial hemorrhage developing after endovascular occlusion of a pial AVF have not been adequately reported. Case description A 37-year-old man presented with left middle cerebral artery (MCA) AVF and right posterior cerebral artery (PCA) AVF with giant venous pouches. Staged endovascular coil embolization was performed. The MCA AVF was completely occluded by coils at the first stage. Intravenous heparin (3000 IU) was administered during the procedure, and then low molecular weight heparin (subcutaneous injection, 0.4 mL/12 hours) was administered for two days. The PCA AVF was near completely occluded by coils without anticoagulation therapy at the second stage. Rapid progressive venous thrombosis and intracranial hemorrhage were confirmed by computerized tomography brain scan postoperatively, and the patient was then transferred to the neurological intensive care unit for further treatment. Finally, the patient recovered well at the five-month follow-up. Conclusions Endovascular occlusion of a high-flow pial AVF with a giant venous pouch resulting in significant blood stasis could precipitate thrombosis in the venous system. Further studies are required to establish whether anticoagulation therapy is necessary.
