【摘要】 目的探讨下肢静脉血栓临床与声像图特征之间的关系,使临床医生能够透过声像图特征,看到患者当前下肢静脉血栓所处的状态。方法受检患者均为单侧性下肢静脉病变。根据患者临床特点将入选患者分为三组。A组(急性期):48例,为发病后48小时内行超声检查者。B组(慢性组):46例,为反复发作、时轻时重的患侧肢体肿胀及疼痛者。C组(无症状组):32例,患者无明确下肢肿胀及疼痛不适感,是临床怀疑或已经发生肺栓塞而例行超声检查者。测量所有病变处血管内径及对侧相同部位的血管内径,并进行比较。结果A组:病变处血管内径增宽,与对侧比较,差值平均为2.1±1.1mm。病变处血管管壁清晰、光滑、完整,探头加压管腔不能压瘪,内有实性回声充填。彩色及能量多普勒显示病变处血管内无血流信号,或有不规则虫蚀样血流信号。B组:病变处血管管壁不规则性增厚,回声增强,管壁显示模糊不清,管腔不同程度变窄。彩色及能量多普勒显示血管内血流信号不规则性变细、断续或成虫蚀蚯蚓样。病变处血管内径较对侧同等部位内径变窄,其差值平均为1.6±0.9mm。C组:本组特点是以等回声或中等偏高性小附壁血栓为主,主要发生在小腿静脉及肌间静脉内。病变处血管内径与对侧同等部位比较,血管内径无变化。结论实时声像图不仅能够显示下肢静脉有无血栓,而且可以了解血栓所处的状态。更多还原

【Abstract】 Objective To study the relations between its clinic and sonographic features in lower limbs vein thrombus,so that the clinicians could learn the thrombus stage at present.Methods All patients in the experiment suffered from single lower limbs vein thrombs.According to patients’ clinic features,all the patients enrolled would be divided into three groups.A group(acute episode):48 patients.They were examined within 48 hours from the beginning of the disease.B group(chronic episode):46 patients.They experienced recurrent,sometime mild or severe symptoms of swelling and pain extremities.C group(no symptoms):32 patients.The patient had no swelling and pain lower limbs or any other discomfort.Most were doubtful of having or had been lung embolism clinically,so that they were required doing the ultrasonography.All the patients were only one lower limb illness,and compared their diameters with the other healthy limbs.Results A group:The sick vein diameter increased when compared with the other healthy.This difference averaged 2.1±1.1 mm.The sick vein walls were clean,slick and integrated,and their vein lumens which full of solid echo did not vanished with pressing the transducer The color and energy Doppler displayed no flow or a littler flow like-worm in the site.B group:The walls of the sick vein thickened unequally,their echo brightened and were unidentifiable,their lumen narrowed in various degrees.The color and energy Doppler showed that the flow signal in the vein thinned anomaly,broken or like-worm.The diameter of the sick vein thinned compared with the other healthy veins,their average difference were1.6±0.9mm.This group mostly features were that the small equal-echo or little more thrombosis attached to the vein wall, and of most attached calf veins and inter-muscle vein.Compared their diameters with the others,no change was found.Conclusion The real ultrasonography was not only able to image whether or not lower limb venous with thrombosis,but also to know its status更多还原
