目的探索经足背静脉行下肢静脉CO2DSA的可行性及效果。方法15例患者(15条患肢),男9例,女6例,临床疑为下肢深静脉血栓形成8例,大隐静脉曲张6例,下肢深静脉血栓溶栓术后复查1例。分别用8号头皮针经足背静脉行下肢静脉CO2DSA。结果12例造影可清晰显示下肢浅、深静脉及其交通支,血栓、血管狭窄的位置及范围,图像质量优;2例造影图像质量良;1例因脚背严重水肿,多次足背静脉穿刺未成功而致造影失败。术中3例无任何不适反应;11例出现下肢一过性不适,主要表现在足背静脉穿刺点处一过性胀痛,其中6例下肢深静脉血栓形成患者感觉明显,停止注射不适感即除;本组未出现重度不良反应或并发症患者。结论下肢静脉顺行性CO2DSA安全、可行,能够满足临床下肢静脉疾病的诊断要求,尤其是对于髂静脉、下腔静脉的显示效果尤佳。
Objective To explore the feasibility and effect of CO2DSA through the dorsalis veins. Methods Fifteen patients (15 limbs), 9 males and 6 females, were enrolled in this study. There were 8 cases of deep venous thrombosis in lower limbs, 6 cases of great saphenous vein, and 1 case after deep thrombolysis in lower extremities. Scalp acupuncture on the 8th was performed through the dorsal vein to lower extremity venous CO2DSA. Results The location and extent of the superficial and deep veins of the lower extremities and their traffic branches, blood clots and blood vessels stenosis were clearly shown in 12 cases. The image quality was good. Two cases had good imaging quality. One case had severe dorsal foot edema, multiple dorsal venous puncture Failure to radiographic failure. There was no discomfort reaction in 3 cases and 11 cases had transient discomfort of the lower extremities. The main symptoms were transient tenderness at the puncture point of the dorsal venous dorsum, of which 6 patients had deep sensation in deep venous thrombosis, In addition, this group did not appear in patients with severe adverse reactions or complications. Conclusions The posterior extremity antegrade CO2DSA is safe and feasible, which can meet the diagnostic requirements of clinical lower extremity venous diseases, especially for iliac vein and inferior vena cava.
