Posterior Spinal Artery

Background/objectiveThe concomitant origin of the anterior spinal artery (ASA) or the posterior spinal artery (PSA) from the feeder of a spinal dural arteriovenous fistula (SDAVF) is rare and the exact incidence is not known. We present our experience with the management of SDAVFs in such cases.MethodsIn 63 patients with SDAVF between 1993 and 2015, the feeder origin of the SDAVF was evaluated to determine whether it was concomitant with the origin of the ASA or PSA. Embolization was attempted when the patient did not want open surgery and an endovascular approach was regarded as safe and possible. The outcome of the procedure was evaluated as complete, partial, or no obliteration. The clinical outcome was evaluated by Aminoff–Logue (ALS) gait and micturition scale scores.ResultsNine patients (14%) had a concomitant origin of the ASA or PSA with the feeder. There were two cervical, five thoracic, and two lumbar level SDAVFs. A concomitant origin of the feeder was identified with the ASA (n=7) and PSA (n=2). Embolization was performed in four patients and open surgery was performed in five. Embolization resulted in complete obliteration in three patients and partial obliteration in one. Using the ALS gait and micturition scale, the final outcome improved in six while three cases remained in an unchanged condition over 2–148 months.ConclusionsThe concomitant origin of the ASA or PSA with the feeder occurs occasionally. Complete obliteration of the fistula can be achieved either by embolization or open surgery. Embolization can be carefully performed in selected patients who are in a poor condition and do not want to undergo open surgery.

Slight Growth

Little is known on the natural history of ruptured isolated aneurysms of the posterior spinal artery (PSA). To date, only a few of such cases have been described in the literature. This paper aims to assess the most appropriate management strategy, based on the available literature and two new cases. In one of these, treatment was postponed until day 33, when angiography showed slight growth of the aneurysm. In the other, conservative treatment, requested by the patient, was successful. From these data, we conclude that treatment strategies for ruptured PSA aneurysms may vary. Aside from the recommendation by others to perform prompt surgical treatment, we suggest an alternative clinical paradigm allowing for the evaluation of the early clinical course. This may preclude the unnecessary treatment of spontaneously regressing lesions and still allows for appropriate treatment for persistent lesions.

Abstract BACKGROUND AND IMPORTANCE: Because of their rarity, the pathogenesis and clinical features of isolated spinal artery aneurysms are still unclear, and their diagnoses and treatments are challenging. We report a case of an isolated posterior spinal artery aneurysm and review previous reports thoroughly to identify the general features of isolated spinal aneurysms. CLINICAL PRESENTATION: A 52-year-old man presented with abdominal pain followed by back pain and radiculopathy from subarachnoid hemorrhage in the spinal canal. The spinal angiogram demonstrated the presence of a dissecting aneurysm of the posterior spinal artery. He was treated by endovascular occlusion of the origin of the radiculopial artery and recovered completely. CONCLUSION: Isolated spinal artery aneurysms are very rare lesions; however, they should be considered in patients with intracranial or spinal subarachnoid hemorrhage without evidence of arteriovenous malformations. Spinal aneurysms have different etiologies compared with intracranial aneurysms. Cervical aneurysms have worse outcomes than thoracolumbar aneurysms. The etiology and location of the lesion and distal flow to the lesion should be taken into consideration when planning the treatment.
