Spine surgery is entering a new era of evolution, with minimally invasive spine surgery to decompress the neural structures without affecting the stability of the spine. However, complications may occur. The surgeon must have these in mind in order to prevent them. We report on the main intraoperative and postoperative complications of endospine surgery of lumbar disc herniation. ⋯ Twenty-two years of follow-up on endospine treatment for lumbar disc herniation showed a low complication rate. An early and efficient management will nevertheless allow a good outcome in the majority of patients operated.

Acute subdural hematomas are frequently seen in brain trauma-injured patients. However, spontaneous subdural hematomas are uncommon, especially those localized in the posterior fossa, where fewer than 10 case reports have been described in the medical literature. ⋯ The patient had a great outcome, with no neurologic deficits at hospital discharge and the 1-year follow-up.

In percutaneous endoscopic transforaminal discectomy (PETD), surgeons are exposed to intraoperative radiographic radiation over a long-term career, which may be correlated with high risk of iatrogenic radiation hazards. The purpose of this prospective cohort study was to assess the impact of concentric stereotactic technique on radiation exposure to surgeons in PETD. ⋯ The concentric stereotactic technique can effectively reduce radiation exposure to surgeons by about 40%.

We analyzed the applicability of the Simpson grading system to estimate the risk of tumor recurrence after microsurgery for recurrent meningiomas. ⋯ Surgery for recurrent meningiomas is not generally associated with an increased risk of postoperative complications compared with resection of primary diagnosed tumors. However, the Simpson grade and EOR in recurrent meningiomas correlated poorly with further tumor relapse. The lower prognostic value of the tumor remnants left behind during microsurgery for recurrent meningiomas should be considered when operating on lesions that can be surgically challenging.

Case Reports
Transforaminal endoscopic excision of intradural lumbar disc herniation and dural repair: A case report.
Intradural disk herniation is a rare entity with <0.3%-1% of all disk herniations and at an L2-L3 level even rarer. The dural defects repairs on ventral aspect are technically challenging and may not be possible after durotomy, so many authors have placed fascia, muscle, or plugging by the hemostatic material. The surgical treatment of intradural disk herniation is usually posterior open surgery with formal durotomy to remove the disk fragments with good to fair results. Poorer outcome occurs in late-presenting cases. ⋯ To our knowledge, this is the first case of transforaminal endoscopic treatment of intradural disk herniation at an L2-L3 level in which good clinical outcomes were obtained and maintained until recent follow-up of 8 months.
