戴戒术与单纯浅静脉剥脱术治疗原发性下肢深静脉瓣膜功能不全的比较

目的:比较股浅静脉戴戒术与单纯性浅静脉剥脱术治疗下肢深静脉瓣膜功能不全的疗效。方法:将2010年03月—2011年1月收治的48例下肢深静脉瓣膜功能不全伴静脉曲张患者随机分为观察组(股浅静脉戴戒术联合大隐静脉高位结扎剥脱术)和对照组(传统大隐静脉高位结扎剥脱术),通过彩色多普勒检测两组术前及术后股总静脉血管内径、平均血流速度及Valsalva试验下反流持续时间的变化。结果:与术前比较,术后两组患者的静脉瓣膜功能及血流动力学均明显改善,表现为股总静脉管径缩小、平均血流速度增快、静脉血流反流时间缩短(均P<0.05),但观察组上述3个变量手术前后变化程度(差值)均明显大于照组(均P<0.05)。结论:两种手术方式均是治疗下肢深静脉瓣膜功能不全的有效手段,但戴戒术的治疗效果优于单纯性浅静脉剥脱术。

Comparison between encircling constriction and simple superficial vein stripping in treatment of lower limb deep venous valve insufficiency

Objective: To compare the clinical efficacies between encircling constriction of superficial femoral vein and simple superficial vein stripping in treatment of valve incompetence of the lower limb deep veins. Methods: Forty-eight patients with lower limb deep venous valve insufficiency and varicose veins admitted from March 2010 to January 2011 were randomly assigned to observation group (undergoing encircling constriction of superficial femoral vein combined with high ligation and stripping of the great saphenous vein) and control group (receiving high ligation and stripping of the great saphenous vein only). The inner diameter and average blood flow velocity of the common femoral vein and venous reflux time in response to Valsalva maneuver of the patients in the two groups were measured by color Doppler sonography before and after operation. Results: Compared with the data before operation, the function of venous valves and hemodynamic state of the patients in both groups were significantly improved after operation, as evidenced by the reduced inner diameter and accelerated average blood velocity of the common femoral vein and shortened venous reflux time (all P<0.05). However, the changing amplitudes of the above three variables before and after operation in observation group were all significantly greater than those in control group (all P<0.05). Conclusion: Both of the encircling constriction technique and simple superficial vein stripping procedures are effective for treatment of lower limb deep venous valve insufficiency, while the efficacy of encircling constriction technique is superior to that of simple superficial vein stripping.
