Subjects' hands were then imaged on a 3T clinical MR scanner(Siemens Biograph MMR) using an 8-channel special purpose phased array carotid coil. Lastly, subjects' hands were imaged on a 7T clinical MR scanner(Siemens Magnetom 7T Whole Body Scanner) using a custom built 8-channel transmit receive carotid coil. All three imaging modalities were subjectively analyzed for image quality and visualization of the vessel wall. RESULTS Results of this very preliminary study indicated that vessel wall imaging of the superficial palmar arch was feasible with a whole body 7T and 3T MRI in comparison with micro-ultrasound. Subjective analysis of image quality(1-5 scale, 1: poorest, 5: best) from B mode, ultrasound, 3T SPACE MRI and 7T SPACE MRI indicated that the image quality obtained at 7T was superior to both 3T MRI and micro-ultrasound. The 3D SPACE sequence at both 7T and 3T MRI with isotropic voxels allowed for multi-planarreformatting of images and allowed for less operator dependent results as compared to high frequency microultrasound imaging. Although quantitative analysis revealed that there was no significant difference between the three methods, the 7T Tesla trended to have better visibility of the vessel and its wall. CONCLUSION Imaging of smaller arteries at the 7T is feasible for evaluating atherosclerosis burden and may be of clinical relevance in multiple diseases.展开更多

The aim of this study was to determine the relationships of the PCBMN to both surface and bony landmarks using reliable methods. Ten pairs of forearms from cadavers aged 73 to 98 years were dissected. The PCBMN was identified and its course and relationships documented. The situation of the PCBMN was quantified relative to the distal wrist crease, bistyloid line, scaphoid tubercle, radial styloid process and flexor carpi radialis tendon. A PCBMN was identified on 90% of sides. The PCBMN arose from the radial aspect of the median nerve 52.4 (SD 31.0) mm from the bistyloid line and entered the transverse carpal ligament 10.9 (SD 9.5) mm proximal to the bistyloid line. At the level of the distal wrist crease the PCBMN was located 0.6 to 7.5 mm (mean 4.5;SD 1.9 mm) from the ulnar aspect of the flexor carpi radialis tendon. The inter- and intra-observer reliability of the measurement methods ranged from ICC 0.96 to 1.00. Detailed morphometric data of the PCBMN relative to bony landmarks contribute to knowledge of the spatial relationships of the PCBMN to inform the precision of surgical incisions.展开更多

Twenty-two of them were less than 55 years old(Y-group, n = 22); the others were 55 and older(O-group, n = 65). In surgically excised representative tissue samples, a histomorphometric analysis of the perforating arteries of the palmar aponeurosis and stereologic analysis of hypodermis vascularity were performed. The method of laser flowmetry estimated the microcirculation of the skin of the palm.RESULTS Frequency of cases with rapid development of contracture(less than 5 years) was 13.6% in the Y-group and 40% in the O-group, P < 0.05. The external and luminal diameters of perforating arteries in palmar fascia were decreased more severely in Y. The thickness of intima increased three times compared with healthy control, and the intima/media relation also increased, especially in O. Increased numerical and volumetric micro-vessel densities in hypodermis, percentage of large vessels(more than 12 μm in diameter), and percentage of vessels with signs of periadventitial inflammatory infiltration were noted in Y. The percentage of vessels with adventitial fibrosis was greater in O than in Y. Base capillary flow in Y was increased compared to healthy control subjects and to O, and peak capillary flow was increased in comparison with control.CONCLUSION Compared to the O-group, Y-group patients exhibited more severe constrictive remodeling of palmar fascia perforating arteries supplying hypodermis but more expressed compensatory changes of its capillarization.展开更多

Recently, thoracoscopic techniques have allowed surgeons to offer these patients a permanent solution with minimal surgical trauma. Methods:From June 1996 to July 2002, 78 thoracoscopic sympathectomies(TS) were performed. There were 28 males and 50 females with a mean age of 22.4 years (range, 14 to 48 years). The procedures were performed with the patients under general anesthesia using a double-lumen endotracheal tube. In palmar hyperhidrosis the second thoracic sympathetic ganglia are destroyed by electrocautery. In axillary hyperhidrosis the second to fourth ganglion are cut off. Each lung was reinflated on completion of the sympathectomy, and residual pneumothorax aspirated before closure of the incisions. No placement of chest tubes was performed in the operating . Results:All sympathectomies were completed thoracoscopically. The symptoms disappeared completely in all patients immediately after the operation. Their hands were dry and warm when they waked up from anaesthesia. There was no surgical mortality. Median operation time for a bilateral procedure is 28 min. (range, 8-90 min). The average hospital stay was 5.5 days. The mean follow-up time was 43.8 months (range, 3-73months). Compensatory hyperhidrosis was found in 41.03% (32/78) of patients, but the symptoms were not serve enough to interfere with lifestyle, and were not required further treatment. In all 78 patients had a satisfactory result, without recurrence of palmar or axillary hyperhidrosis.Conclusions:Thoracoscopic sympathectomy is the most effective and minimally invasive treatment for palmar and axillary hyperhydrosis.展开更多

This study was conducted to examine the relevance between CS and the sympathetic segment being transected in the surgical treatment of palmar hyperhidrosis, and thus to detect the potential mechanism of the occurrence of CS. Methods Between October 2004 and June 2006, 163 patients with primary hyperhidrosis were randomly divided into two groups, T3 sympathicotomy （78 patients） and T4 sympathicotomy（85）, who were operated upon under general anesthesia via single lumen intubation and intercostal video-mediastinoscopy （VM）. Results No morbidity or mortality occurred. Palmar hyperhidrosis was cured in all patients. Follow-up（mean （13.8i-6.2） months） showed no recurrence of palmar hyperhidrosis. The difference of rates of mild CS in groups T3 and T4 was of no statistical significance. The rate of moderate CS was significantly lower in group T4 than in group T3. No severe CS occurred. Conclusion The rates of occurrence and severity of CS are lowered with the lower sympathetic chain being transected.展开更多

The purpose of this study was to decide which one of using electrocautery hook and titanium clip is the appropriate procedure for primary palmar hyperhidrosis by assessing the compensatory sweating （CS） and quality of life （QOL） of patients after sympathetic block. Methods Between October 2007 to August 2010, 120 patients with primary palmar hyperhidrosis were randomly divided into two groups, electrocautery hook group （60 patients） and titanium clip group （60 patients）. All patients were treated by sympathetic block at T4 level. The CS was graded based on severity and location; the QOL was classified to 5 different levels based upon the summed total scores （range from 20 to 100） before and after surgery. The variables were compared. Results The postoperative follow-up period was 2 months. All patients were cured. Three patients in electrocautery hook group and 1 patient in titanium clip group had a unilateral pneumothorax on chest X-ray, but none of them was necessary to have chest drainage. Neither perioperative mortality nor serious complications such as cardiac arrhythmia or arrest were observed during the operation. No bradycardia or Horner＇s syndrome occured. CS was not more common in patients in titanium clip group than in those in electrocautery hook group （P=0.001）. Moderate and severe CS was few in all patients, and there was no significant difference between two groups （P=0.193）. Most of the patients feel a notable improvement of the the QOL; nevertheless, there was no significant difference between the groups （P=0.588）. Conclusions Both electrocautery hook and titanium clip used for sympathetic block at the T4 level are effective, safe, and minimally invasive for palmar hyperhidrosis. Because of the lower severity of CS and the similar improvements in the QOL after operation, we prefer to use of titanium clip for treating palmar hyperhidrosis.展开更多

Among these patients （21 male and 9 female）, 5 patients had chronic injuries over 10 days, and 6 patients had fracture of the distal radius epiphysis. The time between injury and treatment ranged from 1 to 30 days. Among them, 11 patients with right-sided fractures and 19 patients with left-sided fractures were operated via the palmar longitudinal incision approach. Results： The results were evaluated after an average of 18 months ranging from 5 to 36 months after operation. The recovery time of fracture was from 4 to 8 weeks and all incisions were primary healing with an average of 6 weeks. Nonunion, delayed union, early closure of distal radial epiphysis, and wrist varus/valgus deformity were not found in all the cases. Based on Gartland and Wereley wrist score assessment undertaken three months after operation, excellent scores were achieved in 24 cases, good scores in 3 cases, acceptable scores in 3 cases. Conclusion： The palmar approach with K-wire fixation via a front longitudinal incision in the treatment of children＇s distal radius extension type fracture has following advantages： （1） easy to reposition for both fresh and old fractures; （2） less damage to surrounding tissues and epiphysis; （3） quick recovery. It is suitable to treat children＇s distal radius extension type fracture.展开更多
