Total uncinate process resection or uncinectomy is often required in the setting of severe foraminal stenosis or cervical kyphosis correction. The proximity of the uncus to the vertebral artery, nerve root, and spinal cord makes this a challenging undertaking. Use of a high-speed burr or ultrasonic bone dissector can be associated with direct injury to the vertebral artery and thermal injury to the surrounding structures. The use of an osteotome is a safe and efficient method of uncinectomy. Here the authors describe their technique, which is illustrated with an intraoperative video.

Objective In cases of hemifacial spasm caused by a tortuous vertebrobasilar artery (TVBA), the traditional treatment technique involves Teflon (polytetrafluoroethylene), which can be ineffective and fraught with recurrence and neurological complications. In such cases, there are various techniques of arteriopexy using adhesive compositions, ‘suspending loops’ made of synthetic materials, dural or fascial flaps, surgical sutures passed around or through the vascular adventitia, as well as fenestrated aneurysmal clips. In the present paper, we describe a new technique of slinging the vertebral artery (VA) to the petrous dura for microvascular decompression (MVD) in a patient with hemifacial spasm caused by a TVBA. Method A 50-year-old taxi driver presented with a left-sided severe hemifacial spasm. A magnetic resonance imaging (MRI) scan of the brain showed a large tortuous left-sided vertebral artery impinging and compressing the exit/entry zone of the 7th and 8th nerve complex. After a craniotomy, a TVBA was found impinging and compressing the entry zone of the 7th and 8th nerve complex. Arachnoid bands attaching the artery to the nerve complex and the pons were released by sharp microdissection. Through the upper part of the incision, a 2.5 × 1 cm temporal fascia free flap was harvested. After the fixation of the free flap, a 6–0 prolene suture was passed through its length several times using the traditional Bengali sewing and stitching techniques to make embroidered quilts called Nakshi katha. The ‘prolenated’ fascia was passed around the compressing portion of the VA. Both ends of the fascia were brought together and stitched to the posterior petrous dura to keep the TVBA away from the 7th and 8th nerves and the pons. Result The patient had no hemifacial spasm immediately after the recovery from the anesthesia. A postoperative MRI of the brain showed that the VA was away from the entry zone of the 7th and 8th nerves. Conclusion The ‘prolenated’ temporal fascia slinging technique may be a very good option of MVD in cases in which the causative vessel is a TVBA.

Abstract BACKGROUND AND IMPORTANCE: This technical note describes a complication related to the use of the Merci embolectomy device not previously reported. The device can induce critical flow limitation within an accessed vessel because of a combination of vasospasm and anatomic conformational changes. Furthermore, this can limit the safe removal of the device from intracranial vasculature. We present a novel rescue technique that can be used to safely retrieve the entrapped Merci device without inciting localized vessel injury. CLINICAL PRESENTATION: A 51-year-old male with embolic occlusion of the distal basilar artery and dissection-related occlusion of the left cervical vertebral underwent mechanical thrombolysis. Flow-limiting vasospasm and/or anatomic conformational changes/ telescoping of the intracranial right vertebral artery segment was induced during deployment with subsequent entrapment of the device. Reclamation of the entrapped device was performed by initially removing the Merci microcatheter. The entrapped and fixated device was then resheathed into a 4F slip catheter within the intracranial vertebral artery. The Merci device and the slip catheter were then removed. Right vertebral and proximal basilar artery flow was reestablished after removal of the Merci device. Successful clot extraction was thereafter performed using a microsnare. CONCLUSION: In vitro assessment of the device has demonstrated its propensity to induce vasospasm. In vivo entrapment of the device has not been previously reported. Successful retrieval can be achieved if the Merci device becomes entrapped and fixated. This may be an important consideration as increased utilization of the device occurs.

Brown Sequard Syndrome

This study reports on a 67-year-old woman with partial Brown-Séquard syndrome due to a recurrent cervical neurenteric cyst at C3 to C4. The myelopathic symptoms reappeared 22 years after a previous shunting operation performed posteriorly with a silicone tube connecting the intradural cervical cyst cavity to the subarachnoid space. We have now succeeded in removing the cyst nearly completely with the anterior approach. The surgical procedure consisted of right vertebral artery exposure at C3 and C4 and a subtotal corpectomy of C3 followed by microdissection of the cyst, duraplasty, and iliac strut graft fusion. Spinal cord monitoring with motor-evoked potential studies helped us safely dissect the cyst wall tightly adhering to the spinal cord. Duraplasty with Gore-Tex patch-grafting in conjunction with postoperative lumbar subarachnoid drainage worked well in preventing a spinal fluid fistula. At two years after surgery, the patient showed a nearly complete return of function without any recurrence of the cyst.
