“…ICG reveals the transition from the spinal artery to the medullary vein and is very useful in removing or closing the fistula orifice (59,60). When intraoperative ICG cannot be performed, intraoperative ultrasound is also a good option (61,62). Of course, intraoperative DSA assistance is the best choice (32,63).…”

Abstract. Spinal cord perimedullary arteriovenous fistulas (PMAVFs) are rare and belong to type IV spinal cord arteriovenous malformations (AVMs). Little is known regarding the treatment and prognosis of spinal cord PMAVFs. In the present study the relevant literature from PubMed was reviewed, and it was found that these fistulas can occur at all ages but are more common in children. In children, most spinal cord PMAVFs are large and with high flow, begin with bleeding and are frequently associated with hereditary hemorrhagic telangiectasia. However, in adults, most spinal cord PMAVFs are small and with low flow and begin with progressive spinal cord dysfunction. The early diagnosis of spinal cord PMAVFs is generally difficult, and symptoms can be very severe at the time of diagnosis. Digital subtraction angiography remains the gold standard; however, computed tomography angiography and magnetic resonance angiography are also promising. Spinal cord PMAVFs can be treated by endovascular embolization, surgical removal or a combination of the two methods. Most spinal cord PMAVFs show good outcomes after the appropriate treatment, and the prognosis is primarily associated with the blood flow of the PMAVF. For high-flow spinal cord PMAVFs, endovascular embolization is more effective and can lead to a good outcome; however, for low-flow spinal cord PMAVFs, surgical removal or the combination with endovascular embolization is the optimal choice. The prognosis for low-flow types is slightly worse than for high-flow spinal cord PMAVFs in children, but the outcome is acceptable.

“…IOUS was used for brain and spinal lesions especially in intra-axial brain tumor surgeries. Furthermore, intraoperative color Doppler US has been used in intracranial vascular lesions [7], cerebral and spinal AVMs and aneurysms [8], and a spinal perimedullary fistula [9].…”

Spinal arteriovenous malformations (AVMs) may be associated with sensory and motor deficits, bowel or bladder dysfunction, radicular pain or deficit, and back pain. Hemorrhage can occur in the parenchyma leading to the acute onset of symptoms. Neurosurgical resection is one of the way of treatment. Several techniques including intraoperative angiography, dye-injection and the micro Doppler method have proven to be useful during the surgical resection of spinal vascular lesions. Herein, we report our experience with intraoperative ultrasonography (IOUS) and color Doppler ultrasonography guidance for visualizing a spinal cord AVM during surgery. IOUS is a time-saving and noninvasive method for intraoperative imaging of spinal AVM.

Perimedullary arteriovenous fistulas in children: report on six cases

2011

No specific clinical or radiological characteristic of PMAVFs in the pediatric population was observed when our series was compared with a general series. Early diagnosis and timing of the therapeutic intervention seemed to avoid the development of irreversible ischemic myeloradiculopathy and prevented hemorrhage. Treatment for PMAVFs is difficult to standardize because these are extremely rare lesions with different angioarchitecture configurations.
