Spinal vascular lesions are rare and may be classified as a) dural arteriovenous fistulas (AVFs), b) arteriovenous malformations, or c) perimedullary AVFs. In this narrated video illustration, we present the case of a 71-year-old woman who presented with progressive bilateral lower extremity weakness and urinary retention who was diagnosed with a thoracic spinal perimedullary arteriovenous fistula. The diagnostic studies included a thoracic MRI and spinal angiogram. A multilevel thoracic laminoplasty was performed for microsurgical obliteration of the AVF. The techniques of intraoperative angiography, thoracic laminoplasty and microsurgical obliteration and resection of the AVF are reviewed.

Aneurysms of the posterior circulation remain challenging lesions given their proximity to the brainstem and cranial nerves. Many of these aneurysms may best be approached through a retrosigmoid-suboccipital craniectomy with a far-lateral transcondylar extension. In this narrated video illustration, we present the case of a 37-year-old man with an incidentally discovered right-sided anterior inferior cerebellar artery (AICA) aneurysm. Diagnostic studies included CT angiography and cerebral angiography. A suboccipital craniectomy and far-lateral transcondylar extension were performed for microsurgical trapping and excision of the AICA aneurysm. The techniques of the retrosigmoid craniectomy, C-1 laminectomy, condylectomy and microsurgical trapping of the aneurysm are reviewed.
