An appropriate time (5-7 days) of discontinuation of low-dose acetylsalicylic acid (ASA) in patients undergoing surgery for chronic subdural hematoma (CSDH) is recommended. However, patient clinical deterioration often does not allow to wait the recommended time for surgery. Clear guidelines regarding the perioperative management of patients with ASA therapy are still lacking. The aim of this study is to compare the surgical outcome, complications, and mortality of patients suffering from CSDHs who underwent urgent surgery or before and after 5 days of discontinuation of low-dose ASA. ⋯ Our data showed that the time of discontinuation of ASA does not influence outcome.

Giant sacral schwannomas are rare and difficult to treat. Unexpected neurologic deficits after surgery and tumor recurrence should be considered when surgery is performed. We attempt to remove the tumors via piecemeal total or subtotal excision, leaving parts of the capsule adjacent to nerves to preserve the nerves. This study aimed to present the cases of giant sacral schwannoma at our institutions as well as review the relevant literature and to discuss surgical management. ⋯ Adopting an appropriate surgical approach based on the location of the tumor is important. Piecemeal total or subtotal excision, with parts of the capsule adjacent to nerves left behind may help achieve a good outcome, avoiding a postoperative neurologic deficit.

Calcification of intervertebral disc is a common impairment, which has been considered as the degenerative condition of the spine. In clinical practice, we note that the onset of intervertebral disc calcification (IDC) and ossification of the posterior longitudinal ligament (OPLL) can exist simultaneously in some cases, especially in younger children. However, only 8 cases have been reported in detail previously. In addition, controversy remains in terms of the best way to treat this condition. ⋯ Pediatric IDC accompanied with OPLL is much less frequent, but we must be aware of this disease. Since the distribution of this disease is age-specific and sex-specific, further research is necessary. Treatment for IDC combined with OPLL needs to follow the treatment principles as described in the text.

The benefits of minimally invasive spine surgery are attainable only if hospitals have the financial resources to acquire essential equipment. We present a surgical approach readily available to countries where unacceptably expensive materials are the main limitation for use of minimally invasive spine surgery. ⋯ This is a safe and feasible technique with excellent results obtained at low cost and is becoming an attractive surgical option in developing countries.

The surgical resection of large supracerebellar hemangioblastomas (SHBs) is exceptionally challenging due to their vascularity and deep anatomic location and is associated with a high risk of postoperative complications and mortality. Access to the posterior incisural space can be achieved by either an infratentorial supracerebellar approach or occipital transtentorial approach (OTA). However, the optimal surgical strategy has not yet been established. Here, we report 2 cases of large SHBs that were successfully and safely resected via a unilateral OTA with multimodal assistance. ⋯ The combination of an OTA with preoperative embolization and endoscopic assistance may reduce the intraoperative risk and contribute to improved outcome in patients with such clinically challenging tumors.
