Application of indocyanine green videoangiography in surgery for spinal vascular malformations.

We present our recent experience with indocyanine green videoangiography (ICGVA) in intra-operative evaluation of two patients with dorsal spinal dural arteriovenous fistula (SDAVF) and one patient with conus medullaris arteriovenous malformation (AVM). To our knowledge, the latter is the first report of this in the literature. Intra-operative ICGVA was used to identify an early filling vessel and to obliterate the site of fistulous connection.

Thoracic nerve root hemangioblastoma: a rare cause of posterior mediastinal mass.

Background: Hemangioblastomas are benign tumors that occur sporadically or as part of von Hippel-Lindau disease. Occasionally, they have an extramedullary location along the nerve roots and, rarely, are purely extradural.

Case Description: We report a rare case of a completely extradural large hemangioblastoma in a 32-year-old man presenting with radiculopathy and a posterior mediastinal mass.

Carotid endarterectomy: results and long-term follow-up of a single institution.

Objectives: To document our experiences, technical procedure and outcomes of carotid endarterectomy (CEA) in patients with symptomatic carotid stenosis.

Material And Methods: A total of 49 consecutive patients underwent 53 CEAs (three bilateral, one redo) for severe carotid artery stenosis. There were 39 males and 10 females, with mean age of 63 years.

Application of magnetic resonance tractography in the perioperative planning of patients with eloquent region intra-axial brain lesions.

We aimed to assess the role of preoperative diffusion tensor tractography (DTT) in the surgical planning and prognostication of the postoperative outcome of patients with lesions in the eloquent areas of the brain. From 2006 to 2009, 50 patients were preoperatively evaluated with DTT and image-guidance studies. Three-dimensional (3D) color trajectory maps of white-matter tracts adjacent to the lesions were reconstructed.
