“…Different subtypes of spinal vascular malformations have different performance characteristics in MRI. Perimedullary venous fistulae mainly show intradural flow-void shadow and T2-weighted sequence intramedullary high signal in MRI [9]. Spinal vascular malformations are characterized by low signal T1-and T2-weighted images on MRI [10].…”

This article reports a case of spinal vascular malformation. The incidence of spinal vascular malformation is low, the onset of the disease is varied, and the early clinical symptoms are often atypical, making it easy to miss or misdiagnose the disease. In this case, the patient had a sudden onset of headache and was not examined for spinal cord at the beginning, which led to misdiagnosis of the disease at an early stage. This case report and review of the literature will deepen the understanding of spinal dural arteriovenous fistula. The case report and review of the literature are intended to enhance the understanding of spinal dural arteriovenous fistula and to improve the diagnosis and treatment of this disease.

“…PAVFs are ventral and directly fed by anterior spinal arteries, they are subpial in location, whereas those fed by posterior spinal arteries are subarachnoid. When PAVFs occur, the fistula shunts high-pressure arterial blood into the spinal cord vein system, which leads to pial venous reflux and congestion, causing myelopathy (11). PAVFs typically cause clinical symptoms, including a weakness of the lower extremities, urination difficulties and intradural subarachnoid hemorrhage.…”

Spinal perimedullary arteriovenous fistula (PAVF) of the conus medullaris and cauda equina supplied by the artery of Desproges-Gotteron (ADG) is rare. The present study reports such a rare case and also presents a brief literature review. The patient described herein was a 31-year-old female. She suffered sudden weakness in the lower limbs, a condition which was then gradually aggravated. A physical examination revealed paraplegia, and urination and defecation difficulties. Spinal magnetic resonance imaging (MRI) and computed tomography angiography (CTA) revealed extensive perimedullary vein dilation with the involvement of the ADG as the main feeding artery. Digital subtraction angiography (DSA) confirmed a high-flow PAVF supplied by the ADG and artery of Adamkiewicz (AKA). Microsurgical treatment under intraoperative DSA assistance was performed. The PAVF was resected, and immediately following DSA confirmed the complete removal of the PAVF. Following discharge, the patient was prescribed rehabilitation exercises and gradually recovered. A follow-up CTA and MRI confirmed that the PAVF was cured, and her modified Rankin scale score was 2. Therefore, as demonstrated herein, microsurgery with intraoperative DSA assistance may be considered an effective treatment option for PAVFs with ADG.
