Cerebellar hemorrhage following supratentorial craniotomy is a very seldom described but serious complication. The present study evaluates the significance of presurgical and surgical factors that may predispose patients to these bleeding episodes. ⋯ Not one single presurgical or surgical factor can reliably predict the occurrence of cerebellar hemorrhage after supratentorial craniotomy, and the etiology of this entity still remains unclear. The most important keys to minimize the hazardous sequelae are to be aware of this potential complication and to diagnose it early.

When considering the treatment strategies for dural arteriovenous fistulas (DAVFs), it is important to clarify the exact location of the fistula and venous drainage route from both DAVFs and normal brain tissue. DAVFs with leptomeningeal retrograde venous drainage carry a high risk of neurological deficits and require aggressive treatment. When AVFs involve the dural sinus, transvenous embolization via the transfemoral approach is usually the first choice of treatment. For DAVFs draining directly into the cortical veins without dural sinus involvement, transarterial embolization may be a curative treatment. However, when embolization is technically difficult or results in incomplete occlusion, surgical treatment is required. The purpose of the present study was to review our experience with surgical treatment of DAVFs. ⋯ For DAVFs involving the dural sinus, direct operative sinus packing is indicated. For DAVFs directly draining into the cortical veins, surgical interruption of the draining veins is indicated.

Spinal epidural hematoma after spinal puncture such as for injection of steroids for pain management may result in a rare complication of a spinal epidural hematoma causing acute myelopathy. Although this complication is well known with epidural anesthesia, where it is usually seen with impaired hemostasis, there are surprisingly few case reports of epidural hematoma after an epidural steroid block. ⋯ Spinal epidural hematoma after spinal puncture is usually associated with impaired hemostasis. This case illustrates that it may occur in the absence of known risk factors. The delayed onset and the absence of risk factors have implications for the use of this procedure in chronic pain management.

The use of an interbody bone graft during anterior cervical discectomy remains a controversial topic. This study presents the outcome of 64 consecutive patients who underwent anterior cervical discectomy without an interbody fusion. ⋯ Satisfactory results can be attained by discectomy without an interbody fusion in the surgical management of cervical disc disease.
