256排CT静脉成像在下肢静脉病变中的应用价值

摘要

Objective To observe the applicatio n value of 256-slice CT venography in lower extremity venous disease. Methods 29 patients with suspected lower limb patients underwent 256-slice CTV with double acrotarsium venipuncture,and contrast was diluted. Based on the original image, use multi-mode imaging analysis in workstations. All patientss are underwent ultrasound, and DSA of 9 cases. Results Deep and superficial veins of lower extremities of all patients show good, CTV detected simple varicose of lower extremity in 18patients, 5 cases of deep venous thrombosis of lower extremity, congenital arteriovenous fistula in 3 cases of lower extremity, of which 1 combined with phlebangioma, 1 case of lower limb venous malformations-bone hyperostosis syndrome, 2 cases of outside the cavity pressure, 1 cases of lymph nodes, 1 case of cyst. Conclusions 256-slice CT lower extremity venous angiography combined with muti-mode imaging analysis, it can display the location, scope and extent of lower extremity venous disease, establishment of collateral circulation、venous malformations, it can display the vascular lesions caused by external causes, choose the right treatment for clinical method provides objective evidence of reliable, with high clinical value.%　　目的探讨256排CT下肢静脉成像在下肢静脉病变中的临床应用价值。方法29例临床疑诊下肢静脉病变的患者：双足背静脉穿刺、造影剂稀释后行双下肢静脉CT扫描,根据原始图像、利用工作站进行多模式成像分析。所有病例均进行超声检查,9例进行DSA检查。结果29例双下肢深、浅静脉全程显示良好,血液逆流性下肢静脉曲张18例,下肢深静脉血栓形成后完全闭塞5例,先天性下肢动静脉瘘3例,其中1例合并静脉瘤,下肢静脉畸形-骨肥大综合症1例,腔外压迫性病变2例,其中1例为淋巴结,1例囊肿。结论256排CT下肢静脉成像结合工作站多模式成像分析可以全貌显示下肢静脉曲张、下肢深静脉血栓的位置、范围和程度,完整显示畸形静脉、侧枝循环,还可以显示引起病变的血管外部原因,为临床选择正确的治疗方法提供可靠的客观依据,具有较高的临床应用价值。
