Case Reports
Concomitant lumbosacral perimedullary arteriovenous fistula and spinal dural arteriovenous fistula: a case report.
Although multifocal spinal arteriovenous malformations (AVMs) have been reported before, the present case is the first case of 2 different types, including 1 perimedullary arteriovenous fistula and 2 spinal dural arteriovenous fistulas of lumbosacral AVMs, coexisting in 1 patient. We also report the use of hybrid techniques in treatment of concomitant lumbosacral spinal AVMs. ⋯ Multifocal spinal vascular malformations may coexist in 1 case, and standardized spinal digital subtraction angiography, including the bilateral internal iliac arteries and median sacral artery, should be performed to avoid a missed diagnosis. The concomitant phenomenon indicates that venous hypertension may be a risk factor for the development of arteriovenous fistulas. Hybrid techniques are effective in treatment of multifocal and complex spinal AVMs.

Intradural spinal arachnoid cysts (ISACs) with associated neurologic deficits are encountered infrequently. Various management strategies have been proposed with minimal data on comparative outcomes. ⋯ Early treatment with fenestration and partial wall resection allows for cord decompression, syrinx resolution, and gradual resolution of myelopathic symptoms in most cases.

To explore incidence and risk factors of postoperative adjacent segment degeneration (ASD) following anterior decompression and instrumented fusion for degenerative disorders of the cervical spine. ⋯ Patients with degenerative disorders of the cervical spine who receive 2-level cervical fusion and with upper instrumented vertebra at C5 are at high potential risk of ASD.
