Results According to morphology, there were 3 types of superficial venous trunks in the flaps:"I" type,"Y" type and branch type. All types of the superfical venous trunks were the major passages in the venous drainage of the flaps. If the superficial venous trunks were occluded in pedicles, the venous drainage of the flaps almost stoped.

结果：根据形态可将逆行皮瓣中的浅静脉千分为3种类型：&I&形，&Y&形和树枝形，各种类型的浅静脉干都是皮瓣静脉逆向回流的主要通道，如果在蒂部将浅静脉干闭塞，皮瓣的静脉回流基本停滞。

Creating chorioretinal venous anastomosis potentially offers a means of permanently bypassing the site of obstruction to venous outflow, to recovery the retinal blood circulation and to reduce the retinal ischemia. It is one of the methods curing the reason of CRVO and is demonstrated effective in non-ischemic CRVO patients using laser-induced chorioretinal venous anastomosis. Patients with ischemic CRVO have more severe situations and high risk factors of later neovascular complications occuring, the surgery of via a pars plana vitrctomy combined chorioretinal venous anastomosis can be the newest attempting treatment.

其发病机理和病因目前仍未完全阐明，也没有有效的治疗措施；除常规的药物和针对新生血管并发症的视网膜光凝治疗以外，近年来开展的各种旨在重建或恢复视网膜血液循环的激光和手术治疗方法正日益成为眼科界关注的焦点；利用建立脉络膜视网膜静脉吻合途径，使被淤滞的静脉血流经由脉络膜血管流出眼外，促进或者恢复视网膜血液循环，减少视网膜缺血缺氧状态的发生，是多途径CRVO对因治疗的方法之一。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。

"Compared with nonuse of hormone therapy, oral conjugated equine estrogen therapy increases the risk of venous thrombosis dose-dependently, esterified estrogen does not influence venous thrombosis risk, and the use of any estrogen in combination with medroxyprogesterone acetate increases risk as well," the authors write."If replicated, these findings for venous thrombosis may have implications for the choice of hormone in treating menopause-related vasomotor symptoms in perimenopausal and postmenopausal women."

Smith博士同时指出，相较於非荷尔蒙使用者，口服结合性雌激素不论剂量高低都会提高静脉栓塞的风险，脂化雌激素对静脉栓塞并不会造成影响；任何雌激素，只要伴随medroxyprogesterone acetate，都会提高静脉栓塞的风险；如果本项试验适用，就可以选择正确的荷尔蒙疗法，以治疗更年期及停经期妇女的血管舒缩症状。

Methods Taking 25mmHg as standard of leg venous hypertension, by means of triple integral, the optimal pressures against venous hypertension were worked out and four layer bandage was designed in the purpose of sustained pressure regulated compression for the healing of venous ulcers.

以25mmHg为下肢静脉高压标准，用Van'tHoff渗透压定律计算出最佳分段外加压力的数据，并相应进行四层加压包扎的设计。

Results :The deep formal vein,formed by the perforating venous trunk and tributaries of gracilis muscle,converged into the femoral vein 8.6±0.9 cm below the midpoint of inguinal ligament.Its truck was 2.6±0.5 cm long and 6.9±1.1 mm in diameter.In 29 cases,there was 1 valve proximal to the abouchement of the first perforating vein.The deep femoral vein collected the venous blood of the thigh and the knee,the superficial venous blood of the shank.

结果：股深静脉由穿静脉主干及股薄肌支汇合而成，汇入股静脉处位于腹股沟韧带中点下8.6±0.9 cm，主干长2.6±0.5 cm，外径6.9±1.1 mm，29侧各有一个瓣膜位于第一穿静脉汇入处近侧，股深静脉通过其属支收集大腿外侧、后侧、内侧深部及浅静脉回流，并收集膝部深、浅静脉及小腿浅静脉回流。

Results Stable venous thrombus were observed in all inferior caval vein in thrombosis model group, and the proximal part of venous thrombus was unobstructed and consistent with the pathological change of venous thrombosis during acute stage in human body.

结果 采用改良法制作模型后，大鼠下腔静脉内不仅均形成稳定的血栓，而且形成血栓的血管段的近心端保持通畅，符合人体静脉血栓形成急性期的病理演变。

It was concluded that this venous flap were a new kind of venous flap, the arterial perfusion was performed through the perivenous vascular network within the soft tissue pedicle, while the dorsal digital veins provides venous drainage.

由此认为我们设计的单蒂指背静脉皮瓣可能是一种新型的静脉皮瓣，其保留的部分皮肤筋膜中的微动脉血管网能提供皮瓣可靠的血流，而指背静脉提供畅通的回流通道，以此循环方式维持皮瓣成活。

Cases of superior mesenteric venous thrombosis were found, in one case, the SMV was occlusion completely. MSCTA showed the SMV and portal venous unopacification, in the other case, the filling defect was seen in SMV in portal venous, and the strip low density was seen in MSCTA.. The other signs of AMI included bowel wall edema and thickening、massive fluid in the bowel and ascites in all 5 cases, mesenteric edema and pneumatosis in 2 cases respectively.
