BACKGROUND: A definitive cure for an essential hyperhidrosis can be obtained by an upper thoracic sympathectomy. However, this is offset by the occurrence of a compensatory hyper hidrosis as a side effect and it is irreversible. We performed a thoracoscopic sympathetic chain block using an endoscopic clip in order to avoid the compensatory hyperhidrosis. MATERIAL AND METHOD: From Aug. 1998 to Nov. 1998, 42 cases of thoracoscopic clipping of the T2 sympathetic chain were performed. The sympathetic chain was clipped using an endoscopic clip instead of cutting. RESULT: Bilateral procedure took less than 40 minutes and occasionally necessitated one night in the hospital. There were no mortality nor life- threatening complications. Horners syndrome occurred in two cases. At the end of postoperative follow-up(median 3 months), 95.0% of the patients were satisfied with the results. Compensatory sweating occurred in 31 cases(77.5%) where nine of those cases were classified as either embarrassing(6 cases-15.0%) or disabling(3 cases-7.5%). CONCLUSION: Endoscopic thoracic T2 sympathetic chain block using endoscopic clipping is an efficient, safe and minimally invasive surgical method for the treatment of palmar and craniofacial hyperhidrosis and the results were similar to those underwent T2 sympathicotomy. We recommend that patients receive endoscopic sympathetic chain block in summer.

BACKGROUND: The ultrasound guidance in regional nerve blocks has recently been introduced and gaining popularity. Ultrasound-guided supraclavicular block has many advantages including the higher success rate, faster onset time, and fewer complications. The aim of this study was to examine the clinical data according to the varied volume of local anesthetics in the ultrasound-guided supraclavicular block. METHODS: One hundred twenty patients were randomized into four groups, according to the local anesthetic volume used: Group 35 (n = 30), Group 30 (n = 30), Group 25 (n = 30), and Group 20 (n = 30). Supraclavicular blocks were performed with 1% mepivacaine 35 ml, 30 ml, 25 ml, and 20 ml, respectively. The success rate, onset time, and complications were checked and evaluated. RESULTS: The success rate (66.7%) was lower in Group 20 than that of Group 35 (96.7%) (P < 0.05). The average onset times of Group 35, Group 30, Group 25, and Group 20 were 14.3 +/- 6.9 min, 13.6 +/- 4.5 min, 16.7 +/- 4.6 min, and 16.5 +/- 3.7 min, respectively. There were no significant differences. Horner's syndrome was higher in Group 35 (P < 0.05). CONCLUSIONS: In conclusion, we achieved 90% success rate with 30 ml of 1% mepivacaine. Therefore, we suggest 30 ml of local anesthetic volume for ultrasound-guided supraclavicular block.

An 11-year-old girl underwent T4 to L1 posterior instrumented scoliosis correction for adolescent idiopathic scoliosis. Postoperative clinical examination revealed left-sided Horner's syndrome which was preceded by left-sided C8 paraesthesia. The Horner's syndrome resolved after 14 hours following weaning and removal of the epidural catheter. Horner's syndrome following posterior instrumented scoliosis correction associated to epidural use is extremely rare. Surgeons must be aware of the risks of epidural placement and the need for close monitoring of associated complications. Alternative aetiology producing a Horner's syndrome must always be considered because of its devastating long term sequela if missed.

Stellate ganglion block, due to its wide range of indications, is the most widely practiced procedure in pain clinics. We experienced the case of a 44-year-old female patient who developed prolonged Horner's syndrome after the use of stellate ganglion block. The patient recovered spontaneously from the Horner's syndrome after 12 months. If Horner's syndrome should occur, its etiology will need to be assessed. It is also important to assure the patient they will recover from the complication within a year.

Body lateropulsion is a common manifestation of lateral medullary infarction (LMI), and usually associated with vertigo, limb ataxia, sensory disturbance, and Horner's syndrome. However, isolated body lateropulsion as a presenting symptom of LMI is rare, and the responsible lesion for lateropulsion remains uncertain. We report a 71-year-old woman who showed isolated body lateropulsion as a presenting symptom of LMI. Ipsilateral body lateropulsion in our patient may be ascribed to the involvement of the ascending dorsal spinocerebellar tract rather than the descending lateral vestibulospinal tract, which runs more ventromedially.

BACKGROUND: A prospective, double blind study was performed to compare the clinical effect of vertical infraclavicular and supraclavicular brachial plexus block using a nerve stimulator for upper limb surgery. METHODS: One hundred patients receiving upper limb surgery under infraclavicular or supraclavicular brachial plexus block were enrolled in this study. The infraclavicular brachial plexus block was performed using the vertical technique with 30 ml of 0.5% ropivacaine. The supraclavicular brachial plexus block was performed using the plumb bob technique with 30 ml of 0.5% ropivacaine. The block performance-related pain was evaluated. This study observed which nerve type was stimulated, and scored the sensory and motor block. The quality of the block was assessed intra-operatively. The duration of the sensory and motor block as well as the complications were assessed. The patient's satisfaction with the anesthetic technique was assessed after surgery. RESULTS: There were no significant differences in the block performance-related pain, frequency of the stimulated nerve type, evolution of sensory and motor block quality, or the success of the block. There were no significant differences in the duration of the sensory and motor block. There was a significant difference in the incidence of Horner's syndrome. Two patients had a pneumothorax in the supraclavicular approach. There were no significant differences in the patient's satisfaction. CONCLUSIONS: Both infraclavicular and supraclavicular brachial plexus block had similar effects. The infraclavicular approach may be preferred to the supraclavicular approach when considering the complications.

Arterial dissection is an important cause of stroke. We report two cases of isolated posterior inferior cerebellar artery (PICA) dissection diagnosed by high-resolution vessel-wall MRI (HRVW-MRI). One subject complained of abrupt-onset vertigo and headache, and the other subject had headache, vertigo, and Horner syndrome. Conventional MRA showed only focal dilatation of the PICA, but HRVW-MRI revealed intramural hematoma and double-lumen contour in the PICA, suggesting arterial dissection. We suggest that the use of HRVW-MRI should be considered when diagnosing isolated PICA dissection in a PICA infarct with an unknown cause.

BACKGROUND: Horner syndrome (HS), also known as Claude-Bernard-Horner syndrome or oculosympathetic palsy, comprises ipsilateral ptosis, miosis, and facial anhidrosis. CASE REPORT: We report herein the case of a 67-year-old man who presented with congenital HS associated with ipsilateral hypoplasia of the internal carotid artery (ICA), as revealed by heterochromia iridis and confirmed by computed tomography (CT). CONCLUSIONS: CT evaluation of the skull base is essential to establish this diagnosis and distinguish aplasia from agenesis/hypoplasia (by the absence or hypoplasia of the carotid canal) or from acquired ICA obstruction as demonstrated by angiographic CT.
