1/183. An uncommon mechanism of brachial plexus injury. A case report.

    PURPOSE: To report a case of brachial plexus injury occurring on the contralateral side in a patient undergoing surgery for acoustic neuroma through translabrynthine approach. CLINICAL FEATURES: A 51-yr-old woman underwent surgery for acoustic neuroma through translabrynthine approach in the left retroauricular area. She had a short neck with a BMI of 32. Under anesthesia, she was placed in supine position with Sugita pins for head fixation. The head was turned 45 degrees to the right side and the neck was slightly flexed for access to the left retroauricular area, with both arms tucked by the side of the body. Postoperatively, she developed weakness in the right upper extremity comparable with palsy of the upper trunk of the brachial plexus. hematoma at the right internal jugular vein cannulation site was ruled out by CAT scan and MRI. The only remarkable finding was considerable swelling of the right sternocleidomastoid and scalene muscle group, with some retropharyngeal edema. An EMG confirmed neuropraxia of the upper trunk of brachial plexus. She made a complete recovery of sensory and motor power in the affected limb over the next three months with conservative treatment and physiotherapy. CONCLUSIONS: brachial plexus injury is still seen during anesthesia despite the awareness about its etiology. Malpositioning of the neck during prolonged surgery could lead to compression of scalene muscles and venous drainage impedance. The resultant swelling in the structures surrounding the brachial plexus may result in a severe compression.

2/183. The prevention of irreversible lung changes following reversible phrenic nerve paralysis.

    phrenic nerve paralysis frequently follows operations on the neck such as resection of a cervical or first rib. It all too often passes unrecognised or is incorrectly treated, leading to permanent lung damage which may be severe enough as to result in a functional pneumonectomy. This is particularly unfortunate since the phrenic nerve paralysis is usually temporary. Three case histories are described of reversible paralysis of the phrenic nerve in which, due to prompt diagnosis, the ensuing lung changes were either prevented or immediatley treated. Intermittent assisted respiration with a Monaghan respirator was used to provide nebulised inhalations of mesna several times a day. The method is applicable via a tracheostomy, an endotracheal tube or a simple mouthpiece. The latter is illustrated. The therapy is not hindered by immobilisation of the head and neck and the level of consciousness of the patients is of no importance. Many chest x-rays demonstrate the rapid clearing of the lungs achieved. All three patients were discharged with perfectly normal lungs.

3/183. hypoglossal nerve injury as a complication of anterior surgery to the upper cervical spine.

    Injury to the hypoglossal nerve is a recognised complication after soft tissue surgery in the upper part of the anterior aspect of the neck, e.g. branchial cyst or carotid body tumour excision. However, this complication has been rarely reported following surgery of the upper cervical spine. We report the case of a 35-year-old woman with tuberculosis of C2-3. She underwent corpectomy and fusion from C2 to C5 using iliac crest bone graft, through a left anterior oblique incision. She developed hypoglossal nerve palsy in the immediate postoperative period, with dysphagia and dysarthria. It was thought to be due to traction neurapraxia with possible spontaneous recovery. At 18 months' follow-up, she had a solid fusion and tuberculosis was controlled. The hypoglossal palsy persisted, although with minimal functional disability. The only other reported case of hypoglossal lesion after anterior cervical spine surgery in the literature also failed to recover. It is concluded that hypoglossal nerve palsy following anterior cervical spine surgery is unlikely to recover spontaneously and it should be carefully identified.

4/183. Post-traumatic distal nerve entrapment syndrome.

    Eleven patients with paralysis of muscle groups in the upper or lower extremity were clinically diagnosed after previous proximal direct trauma to the corresponding peripheral nerves, without complete nerve disruption. patients were seen within an average of 8 months after trauma (minimum 3 months and maximum 2 years after). Nerve lesions were caused either by gunshot, motor-vehicle accident, and other direct trauma or, in one case, after tumor excision. All patients presented with complete sensory and motor loss distal to the trauma site, but demonstrated a positive Tinel sign and pain on testing over the "classic" (distal) anatomic nerve entrapment sites only. After surgical release through decompression of the nerve compression site distal to the trauma, a recovery of sensory function was achieved after surgery in all cases. Good-to-excellent restoration of motor function (M4/M5) was achieved in 63 percent of all cases. Twenty-five percent had no or only poor improvement in motor function, despite a good sensory recovery. Those patients in whom nerve compression sites were surgically released before 6 months after trauma had an improvement in almost all neural functions, compared to those patients who underwent surgery later than 9 months post trauma. A possible explanation of traumatically caused neurogenic paralysis with subsequent distal nerve compressions is provided, using the "double crush syndrome" hypothesis.

5/183. Newborn radial nerve palsy: report of four cases and review of published reports.

    Four newborns presented with isolated radial nerve palsy during the first 2 days of life. In three, there was a history of failure of progression of labor, which may have resulted in prolonged radial nerve compression. Furthermore, three infants had fat necrosis of the upper arm above the elbow, suggestive of compression of the radial nerve in the region of the spiral groove. Significant recovery of function was evident within 1 month in all four infants. The authors review published reports about the rare condition of isolated radial nerve palsy in the newborn.

6/183. Occipital condyle fracture with peripheral neurological deficit.

    A 24-year-old woman sustained a type III Anderson and Montesano fracture in a road traffic accident. Acute respiratory stridor, multiple cranial nerve palsies and right upper limb neurological deficits associated with a C1 to T2 extradural haematoma were unique features of this case. The patient made a full and uncomplicated recovery with conservative management.

7/183. Physical therapy in a patient with bilateral obturator nerve paralysis after surgery. A case report.

    obturator nerve injury can result from surgical procedures. Bilateral obturator nerve injury developed in our patient as a result of edema in the obturator fossa after a debulking operation. In the postoperative period, neuromuscular electrical stimulation, electromyographic (EMG) biofeedback, exercise and a home treatment program were used as the physical therapy approach. The patient became symptom-free after the physiotherapy program.

8/183. Cruciate paralysis, hypothesis for injury and recovery.

    STUDY DESIGN: Case report and review of the literature. OBJECTIVES: Discuss a case of cruciate paralysis, a review of the literature and the hypotheses regarding the pathogenesis and recovery in spinal cord injuries that cause disproportionate weakness of the upper extremities. SETTING: Thomas Jefferson University Hospital, philadelphia, PA, USA. methods: Case report. RESULTS: A case of cruciate paralysis is presented involving a 59-year-old female who experienced a gunshot wound to the face. Initial motor exams revealed mild lower limb weakness and absent upper limb function with an upper limb modified American Spinal Injury association motor score of 0/50 (a modified impairment scale using half point muscle grades). Spinal imaging revealed fractures of the C1 anterior ring and the odontoid process, both associated with multiple bullet fragments. No spinal surgery was performed and she was placed in halo fixation. By 3 weeks she had regained enough upper limb function to manipulate large objects with her left hand and move her right hand. At that time, her upper limb asia score was 16/50. By 5 weeks, her upper limb modified asia motor score had improved to 31.5/50 and she began manipulating feeding utensils, writing legibly, and brushing her teeth with her left hand. CONCLUSIONS: In this case report we present a patient's motor and functional recovery. We also discuss the hypothesis that the acute central cord syndrome and cruciate paralysis are a likely result of similar pathologic mechanisms and that good functional outcome resulted from an initially disabling trauma.

9/183. Acute bilateral arm paresis.

    OBJECTIVE: To study pure motor bilateral arm paresis of acute onset. This syndrome is as yet a barely described clinical feature attributed to ischemia in the territory of the anterior spinal artery (ASA). CASES: We present 2 patients with acute onset of pure motor deficit in both upper extremities. RESULTS: magnetic resonance imaging of the cervical spinal cord revealed infarcts in the territory of the ASA. In 1 case, electrophysiology further suggested discrete gray matter involvement. CONCLUSION: In patients with acute weakness of both arms without further neurological deficits, an incomplete ASA syndrome should be considered with the anterior horns predominantly being affected. magnetic resonance imaging and electrophysiology are valuable tools to further confirm both location and extension of the spinal lesion.

10/183. A limited anterior petrosectomy with preoperative embolization of the inferior petrosal sinus for ventral brainstem tumor removal.

    BACKGROUND: The present study describes the use of a limited subtemporal extradural anterior petrosectomy with preoperative embolization of the inferior petrosal sinus for the management of tumors located behind the clivus and ventral to the brainstem. Details of the procedure and its application in five cases are presented. methods: This procedure consists of using the extradural route to approach the upper side of the petrosal pyramid so that it can be drilled medially, and to resect the apex to come out into the posterior fossa. This route gives a petrosectomy just medial to the horizontal segment of the petrous carotid artery in front of the cochlea. It goes around the labyrinthine mass and the internal auditory canal from above to expose the posterior fossa dura between the two petrosal sinuses. The dural opening exposes the ventral aspect of the pons from the trigeminal nerve to the origin of the abducens nerve, ventral to the facial nerve. Preoperative embolization of the inferior petrosal sinus allows its intraoperative section for a wider exposure along the lower clivus. This approach can easily be combined with an intradural approach to provide additional exposure above the trigeminal nerve. patients who underwent this procedure had prepontine cisternal chordoma or epidermoid cyst of the petroclival region. RESULTS: One patient experienced a cranial nerve deficit as a direct result of the surgical procedure (VIth nerve palsy requiring surgery) but no other patient has had permanent neuromuscular compromise. Complications consisted of a wound infection in one case. Tumor removal was total in three cases and partial in two cases. CONCLUSION: Quite easy to master, the anterior petrosectomy with preoperative embolization of the inferior petrosal sinus is a time-conserving approach giving one of the best routes to reach the ventral brainstem while working in front of the cranial nerves and preserving hearing.
