We recorded pattern electroretinograms and visual evoked potentials in a group of selected patients with unilateral uncomplicated branch retinal vein occlusion. To document the effects of preexisting risk factors, patients were divided into three groups: diabetes mellitus, hypertension with hyperlipidemia and no systemic disease. The transient and steady-state pattern electroretinogram and visual evoked potential amplitudes were significantly reduced and visual evoked potential peak times were delayed relative to the fellow eyes and agematched normal subjects. There was a second amplitude reduction relative to the other patient groups in both the affected and fellow eyes of the diabetes mellitus group, which was indicative of an additive effect of diabetes mellitus.Abbreviations BRVO

A video-assisted right upper lobectomy was successfully performed on a 58-year-old man with an anomalnous segmental pulmonary
vein. The tumor was a peripherally located adenocarcinoma. The anomalous vein behind the right main bronchus was identified
and safely divided. This case emphasized that to perform this procedure successfully, (1) a careful preoperative evaluation
of the anatomy, including the presence of any possible vascular and/or bronchial anomalies, is necessary, and (2) if any anatomical
structures cannot be determined intraoperatively, a conversion into an open procedure must immediately be undertaken. 相似文献

目的:通过对髂外动静脉及股动静脉与髋臼解剖学与临床的研究,探讨在全髋臼置换术中拉钩在髋放置位置对下肢深静脉血栓的影响。方法:通过解剖学研究56具成年骨盆标本中髂外动静脉及股动静脉来源及走行、与髋臼的关系进行测量分析;并通过临床观察22例(股骨颈骨折12例、股骨头缺血性坏死6例、类风湿性关节炎4例)在人工全髋置换术(THR)中拉钩放置安全区,经下肢静脉超声多普勒检查观察下肢深静脉血栓发病率。结果:在左侧3-5点间、右侧7-9点、左侧9点、右侧3点使用拉钩用力要适度,牵拉时间过长,会造成臀下血管、股动脉的牵拉过度或时间过长,易引起下肢深静脉血栓;通过临床22例THR拉钩放置安全区的观察,无一例下肢深静脉血栓,仅有2例轻度深静脉血流缓慢、但无明显的症状体征,经过口服活血通络中药后消失。结论:通过解剖学与临床观察研究,确定在THR中拉钩放置位置、深度是避免下肢深静脉血栓的重要因素。 相似文献

OBJECTIVE: The purpose of this study was to investigate the incidence of the retroaortic left renal vein (RLRV) in patients with varicocele. METHODS: The left renal vein was ultrasonographically investigated for the presence of the RLRV in 140 patients with varicocele and a control group of 137 age-matched patients. The main diagnostic criteria for varicocele were the presence of a varicose vein with a diameter of 3 mm or larger at rest and with a reflux lasting more than 2 seconds during the Valsalva maneuver. The RLRV was defined as a posterior course of the left renal vein to the aorta at the level of the origin of the superior mesenteric artery. RESULTS: The RLRV was observed in 13 (9.3%) of the 140 patients with varicocele and 3 (2.2%) of the control patients. The incidence of the RLRV was found to be significantly higher in patients with varicocele compared with the control patients (P = .018, Fisher exact test). In 13 patients with the RLRV, left varicocele and bilateral varicocele were detected in 10 and 3 cases, respectively. CONCLUSIONS: In this study, the incidence of the RLRV was found to be significantly higher in patients with varicocele compared with control patients. Thus, we suggest that the presence of the RLRV may be considered one of the etiologic factors in the development of varicocele. 相似文献

The influence of melatonin on tension of isolated bovine pulmonary vascular and bronchial smooth muscle rings were examined in these experiments. Melatonin caused a dose-dependent relaxation of precontracted (30 mM KCl) pulmonary artery and vein, although the effect is greater in arterial smooth muscle. This relaxant response was blocked by preincubating vessels with antagonists of vasoactive intestinal peptide or Substance P. In bronchial smooth muscle, melatonin caused a small contractile response. These experiments demonstrate that in response to melatonin the pulmonary vasculature relaxes, while in airway smooth muscle the reverse, constriction, occurs. It is hypothesized that nocturnal exaggeration of asthma may, in part, be due to changes in circulating levels of melatonin. 相似文献

The use of deep inspiration preceding the valsalva maneuver and rapid expiration in color doppler imaging of the lower extremity veins 总被引:1,自引:0,他引:1

Deep inspiration preceding Valsalva maneuver and rapid expiration immediately following it (DIVE) enhance venous blood flow on color Doppler flow imaging (CDI). The effect of DIVE was assessed in 115 consecutive lower extremity examinations. Of these, 95 or 115 (83%) had negative CDI sonograms, and 20 of 115 (17%) had partially (six of 115) or completely (14 of 115) occluding deep vein thrombosis. DIVE enhanced venous blood flow in 68% of the negative cases, resulting in transient venous distention, and/or more complete color filling, and/or greater spectral flow velocities. The 14 cases with completely occluding thrombi showed no response to DIVE. Six cases with partially occluding thrombi showed moderate to mild response to DIVE, with improved color delineation of the residual patent lumen around the thrombus. The authors conclude that DIVE facilitates deep venous CDI, especially when compression cannot be used to augment venous flow. 相似文献
