静脉的

52 venipuncture failure critically ill patients,after the open-incrision under intravenous needle casing.

方法对52例静脉穿刺失败的危重病人，采用静脉切开后直视下进行目的探讨套管针在静脉切开术中的应用。

Methods Fourteen healthy pigs were anesthetized and intubated, the right carotic artery was cannulated for blood pressure monitoring and blood biochemical sampling.

术中输入不含糖的平衡盐液，供肝用Collin's液灌注。在无肝期采用体外静脉转流，经左侧股静脉和门静脉插管，引流出的血流经体外转流系统输入左侧腋静脉。

METHODS: Rabbit models of autogenous vein graft were generated in both groups. After anaesthesia, a median incision was made at the neck to dissociate external jugular vein and common carotid artery of the left side. Following blood flow was blocked at the upper and down sides of the common carotid artery, blood vessels were transected to collect 4.0-5.0 cm external jugular vein at the left side, and placed among the common carotid artery at the same side after inversion. End-to-end anastomosis was performed using discontinuous ecstrophy.

两组兔均建立自体静脉移植模型，麻醉后颈前正中切口，游离出左侧颈外静脉及颈总动脉，在颈总动脉的上下两端阻断血流后，横断血管，取左侧的颈外静脉4.0~5.0cm，上下倒向后置于同侧颈总动脉之间，采用间断外翻法行端端吻合。

Embryologically, the abnormality most likely develops at gestational weeks four to eight. It is hypothesized that impaired venous outflow, caused by loss of normal connections between cortical veins and dural and calvarial circulation, results in persistent, primitive vascular plexus.

胚胎学上，发育异常最可能发生在孕期的第4-8周，其发病机制被认为是静脉流出受损，这是由于皮层静脉与硬膜及颅盖静脉循环之间的正常连接出现障碍，导致原始血管持续存在。

Gallbladder endoscopicmucosalresectionor open cholecystectomy were applied in 28 cases developed with chronic atrophic cholecystitis and cholecystolithiasis.No hemorrhoea resulted from venae hepaticae intermediae on gallbladder bed injury were occured in all the cases.

术前常规彩色多普勒超声波检查，明确胆囊床肝中静脉及属枝位置关系，对于肝中静脉与胆囊床相贴的病例，采用紧靠胆囊壁的浆肌层剥离，或采用胆囊粘膜切除，或直接开腹手术切除，可以避免因损伤胆囊床肝中静脉而导致大出血。

Although the anatomy of these veins is variable, most vessels drain into the facial vein inferiorly and/or the angular vein as it courses toward the medial orbit.

虽然这些静脉解剖可能发生变异，但是大部分血管都引流至下方的面静脉和/或向眶内侧走行的内眦静脉。

Were used to detect the experimental group and control group, supine position when the left renal vein compression section diameter of the expansion of paragraph a, b, left renal vein peak velocity pressure above Va, the pressure gradient, pressure, as well as the expansion of left renal vein peak velocity Vb paragraph and to observe the two forms of the spectrum, and then testing all the main subjects with renal renal artery, interlobar artery and renal blood flow velocity of the main renal artery resistance index; record of the experimental group urine test subjects in the number of red blood cells.

分别检测实验组及对照组平卧位时左肾静脉受压段、扩张段内径a、b，左肾静脉受压段峰值血流速度Va、压力阶差、压力，以及左肾静脉扩张段峰值血流速度Vb并观察两处的频谱形态，再检测所有受检者双肾主肾动脉、叶间动脉的血流速度及双肾主肾动脉阻力指数；记录实验组受检者尿常规化验中红细胞数量。

Although it is ideal to use the hepatic veins as intersegmental bounderies, their use as such is limited for two many anatomic variations and several segments are boundered by the same hepatic vein.

虽然以肝静脉作为肝段间的分界较为理想，但因其多变异性，和几个肝段由同一肝静脉分界，使肝静脉作为这种标志的价值受限。

Methods 30 patients with trichloroethylene medicamentous dermatitis and 30 normal persons were selected as the observation group and the control group respectively; color Doppler was used to detect the spleen thickness and longitudinal length, spleen vein and artery diameters, the maximum blood velocity and blood flow of spleen vein and artery; RIA was applied to determine the serum levels of HA, LN, PCⅢ, CⅣ and CG; relevant analysis was made on the linear relationship between serum indices of hepatic fibrosis and spleen hemodynamics of the two groups.

选择30例三氯乙烯药疹样皮炎患者作为观察组，30例同时期健康体检者作为对照组，用彩色多普勒超声仪，检测脾脏厚度及长径、脾动静脉直径、脾动静脉血流量和脾静脉最大流速SPV(下标 x。用放射免疫法检测肝纤维化指标透明质酸、层粘连蛋白、Ⅲ型前胶原、Ⅳ型胶原和甘胆酸的水平，并对观察组与对照组的脾血流动力学参数与肝纤维化指标进行相关分析。

A central venous catheter was inserted for hemodynamic monitoring and blood transfusion. Cardiac tamponade occurred secondary to perforation of the superior vena cava by the central venous catheter. The patient's hemodynamic status became stable after pericardiocentesis. One week later she was discharged with no sequelae during the three month follow-up.

患者术后装置中央静脉导管以利於血行动力的评估及输血，病患进行中央静脉导管术时因上腔静脉穿刺破裂导致心包膜填塞及休克，经紧急照会心脏科医师后立即给予心包膜穿刺术，术后患者血压渐趋稳定情况好转於一星期后出院，经过三个月的追踪亦无后遗症。
