C-stopper coil (CSC) which are available for 0.018-inch inner diameter microcenter have been used for neurointervention such as transarterial embolization (TAE) of feeding artery. Although various shapes of pushable microcoils have been developed, microcoils are usually short to embolize the lesion and require lots of coils. The most specific feature of CSC is the extended length of 18 cm. To e...

A 43 year-old female patient suffered the sudden onset of pulsatile tinnitus in the left ear 2 months ago. The tinnitus did not subside spontaneously and remained unchanged. The patient had no history of head trauma or surgery of the head and neck. The character of the tinnitus was pulsatile, and it was synchronous with the heart beat. Audiologic examinations were performed and all of the resul...

spinal dura mater or to enlarge the spinal dural sac is not an infrequent requirement in neurosurgery. Some of the more common spinal conditions include Chiari malformations, tethered cord, syringomyelia, and malignant intradural tumors. A postoperative inflammatory reaction followed by fibrosis involving the arachnoid membrane may lead to various complications. When dense adhesions between the...

Metrizamide computed tomographic myelography demonstrates well: partial- and full-thickness diastematomyelia; the presence, shape, and (a)symmetry of the two hemicords; focal persistence of two anterior spinal arteries, one supplying each hemicord; the single or double subarachnoid space(s), arachnoid tubes, and dural tubes which encompass the hemicords; the dural septum formed by the medial wa...

One hundred patients aged 18-49 yr, undergoing elective arthroscopy of the knee joint, were allocated randomly to either spinal anaesthesia using a 29-gauge spinal needle or general anaesthesia. Dural puncture was considered difficult in 18% of the patients receiving spinal anaesthesia. In three patients (6%) it was necessary to supplement the spinal anaesthetic with general anaesthesia. Spinal...

We present the case of a woman who presented with weakness of both legs due to a low grade tumor of the spinal cord. Excision of the tumor was performed and confirmed with intraoperative ultrasound. Prior to dural closure the spinal cord was found to be pushed dorsally with herniation of the cord through the dural defect. Intraoperative ultrasound showed a collection of cerebrospinal fluid in a...
