Surgical resection has been shown to prolong survival in patients with glioblastoma multiforme (GBM), although this benefit has not been demonstrated for reoperation following tumor recurrence. Laser interstitial thermal therapy (LITT) is a minimally invasive ablation technique that has been shown to effectively reduce tumor burden in some patients with intracranial malignancy. The aim of this study was to describe the safety and efficacy of LITT for recurrent and newly diagnosed GBM at a large tertiary referral center. ⋯ LITT can safely reduce intracranial tumor burden in patients with GBM who have exhausted other adjuvant therapies or are poor candidates for conventional resection techniques.

To evaluate outcomes of thrombectomy in patients with a basilar artery occlusion (BAO) and mild symptoms, defined by an initial National Institutes of Health Stroke Scale (NIHSS) score ≤6. ⋯ Thrombectomy seems to be safer and more effective for mild BAO strokes with NIHSS score ≤6 than for more severe patients. Even although thrombectomy showed high rates of recanalization, a substantial proportion (32%) nevertheless had a poor long-term clinical outcome. The number of passes, patient's age, and stroke cause seem to be predictors of clinical outcome.

Postoperative spinal epidural hematoma is a rare complication of anterior cervical discectomy and fusion. This condition may rapidly produce severe neurologic deficits, often requiring a prompt surgical decompression. A multilevel extension of the epidural bleeding has been rarely described after anterior cervical procedures. In such cases, the choice of the most suitable surgical approach may be challenging. Herein, we describe an effective surgical decompression of a C2-T1 ventral epidural hematoma following anterior cervical discectomy and fusion at the C5-C6 level. ⋯ Although rare, multilevel epidural hematoma following anterior cervical decompression represents a serious complication. The revision of the previous anterior cervical approach may be considered the first treatment option, allowing to control the primary bleeding site. Catheter irrigation of the epidural space with saline solution may be a useful technique for removal of unexposed residual blood collection, avoiding the need for posterior laminectomy or other unnecessary bone demolition.

The aim of this study was to determine the impact of preoperative pulmonary risk factors (PRFS) on surgical outcomes after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). ⋯ Our study showed that PRF may be a risk factor for slightly longer hospital stays without higher rates of complication or unplanned readmission for patients with AIS undergoing PSF and thus should not preclude surgical management.

Spinal hemangioblastomas (SHs) are rare and benign tumors. Primary symptoms include pain, hypoesthesia, and neuropathic pain (NP). Clinical symptoms may be as a result of tumor mass effect, peritumoral effect, syrinx, or venous congestion. No studies have focused on NP in SHs. The objective of this study was to review the rate and causes of NP in patients with SHs. ⋯ The present study shows that NP is observable in both pre- and postoperative periods. Proximity of the tumor to the dorsal root entry zone, and especially the presence of rostral syrinx, are the main factors affecting postoperative NP symptomatology. It is concluded that the combination of these factors and iatrogenic injury of anatomic pathways of NP within the spinal cord are responsible for postoperative NP.
