Sažetak
Aim To report on the outcomes of spinal dural arteriovenous fistulas (sDAVFs) treatment in a single-center retrospective cohort.
Methods Data were retrieved on sDAVF cases treated surgically and endovascularly between January 2009 and January 2020. Sociodemographic, clinical, imaging data, and
outcomes were analyzed.
Results Thirty-four patients were identified: 11 female,
mean age 64.1±11.5 years; mean time of symptom duration 12 (range 1-149) months. The sDAVF locations were
the following: 18 (62.1%) thoracic, 4 (13.8%) lumbar, 4
(13.8%) sacral, and 3 (10%) with multiple location feeders.
All patients had a motor deficit and affected walking, and
the majority had a sensory deficit, bowel, and bladder dysfunction. Fifteen (44.1%) patients underwent surgical treatment, 7 (20.6%) underwent endovascular treatment, and
12 (35.3%) underwent both (crossover). Radiological myelopathy showed regression in 19 (55.9%) patients. Overall,
clinical improvement (decrease in modified Rankin score)
following treatment was observed in 14 patients (41.2%),
worsening in 1 (2.9%), while other had unchanged status. The proportion of patients with initial treatment failure markedly differed between the before-2014 and after-2014 period. Patients who failed to improve had more
extensive myelopathy.
Conclusion Patients who underwent surgery or endovascular treatment had on average significant clinical recovery, while those who underwent treatment crossover had
negligible improvement. The extent of myelopathy seems
to be associated with clinical improvement
