ABSTRACT

Spinal arteriovenous malformations(AVMs) and aneurysms should be suspected when patient present with subarachnoid hemorrhage and intracranial source has not been identified with neurologic findings attributable to the spinal cord. We report a case of subarachnoid hemorrhage(SAH) with ruptured spinal artery aneurysm associated with spinal cord AVM in 37-year old man who presented with sudden loss of consciousness with paraplegia. The result of CT-head arteriography of the brain was SAH with intraventricular hemorrhage but no intracranial aneurysm was identified. Spinal angiography revealed a cervical spinal cord AVM supplied by anterior spinal artery with an aneurysm in the feeder. The treatment of the spinal cord AVM was performed with liquid coil embolic agent, polyvinylacetylate(PVAc) and feeding artery aneurysm was treated with Guglielmi detachable coils(GDCs).

ABSTRACT

OBJECTIVE: Pallidotomy is known to improve the symptoms of idiopathic Parkinson, s disease (PD), motor fluctuations and dyskinesia related to levodopa therapy. Previous studies reported significantly higher complication rates associated with bilateral pallidotomy than unilateral pallidotomy. The authors assess the safety and clinical outcomes of bilateral pallidotomy for advanced PD. METHODS: Simultaneous bilateral pallidotomy was performed in eight patients with advanced PD between January 1, 2001 and December 31, 2001. All patients underwent lesion making in posteroventral site of internal globus pallidus. The target was localized using macroelectrode stimulation and MRI guided stereotactic technique. The lesions were made by radiofrequency currents. RESULTS: Among eight cases, seven had severe disabling dyskinesias. Compared with baseline scores, the values of dyskinesia after surgery was significantly decreased (P<0.05) for up to 1 year. The mean score changed from 4.4+/-2.1 to 0.3+/-0.5. According to Unified Parkinson's Disease Rating Scale (UPDRS), the mean motor score in off period, which was 38.3+/-13.8 was significantly decreased for 6 months (P<0.05). The ADL (on/off) scores and motor "on" scores of UPDRS were unchanged or deteriorated to 12 months after surgery. There was no apparent adverse effect after surgery in all patients. Only transient mild dysphagia happened in one patient. CONCLUSION: Simultaneous bilateral pallidotomy in advanced PD appears to be effective and safe, particularly in reducing the dyskinesia; in our experience, the side effects are not as high as reported by other groups.
