Intraosseous arteriovenous maxillomandibular malformations are rare. The diagnosis is primarily clinical (children with pulsatile osseous tumefaction, bleeding at cingulum), completed with imaging techniques (TDM and/or MRI). Arteriography is indicated only at the time of therapeutic management. The evolution may vary greatly (four levels: quiescence, expansion, destruction, decompensation) and usually evolves because of hormonal changes or trauma. Radiotherapy and vascular ligatures are no longer recommended. The best treatment is direct or transarterial embolization. Surgical resection, when feasible, must be thorough. It is indicated in case of failure or recurrence after embolization.

En bloc resection of intraosseous arteriovenous malformation (AVM) in the maxilla and deformed bone following embolization and sclerotherapy.
Int J Surg Case Rep
November 2024
Department of Plastic Surgery, Kobe University Graduate School of Medicine, Japan.
Article Synopsis
- - Arteriovenous malformations (AVMs) in facial bones, while rare, can lead to serious issues like aesthetic concerns, pain, and significant complications such as life-threatening bleeding.
- - A case study showcased a surgical approach involving preoperative embolization and sclerotherapy followed by the use of specialized devices (Sonopet® and Aquamantys™) to successfully resect AVMs from the maxilla while preserving important structures.
- - The report emphasizes the importance of careful planning and surgical techniques to manage bleeding and ensure effective removal of deformed bone, presenting a promising method for maintaining facial integrity during treatment.

Objective: An intraosseous arteriovenous fistula (AVF) is a rare fistula with an intracranial shunted pouch. A case of an intraosseous AVF at the squamous part of the occipital bone with spontaneous occlusion of diploic venous drainage is described.
Case Presentation: The patient, a Japanese woman in her 80s, presented with headaches at the back of the head and a history of multiple unruptured cerebral aneurysms but no recent head trauma.

Article Synopsis
- A rare case of spinal epidural arteriovenous fistulas (SEAVFs) with intraosseous shunts was observed in a woman in her 70s who experienced severe weakness and urinary retention due to spinal issues.
- Imaging revealed spinal cord edema and venous dilation caused by compressed vertebrae, with angiography showing shunts connected to lumbar arteries.
- Successful treatment involved transarterial embolization, leading to complete closure of the shunt and significant improvement in the patient’s symptoms post-surgery.
