| 目的 探讨16排CT血管成像在腹主动脉及下肢阻塞性病变诊断中的价值。方法 对26例临床疑有下肢动脉硬化、阻塞性病变患者行16排CT容积扫描及血管三维重建,其中15例接受人工血管或支架植入术。结果 26例共494节段,血管重度狭窄97节段,闭塞83节段。95节段行DSA检查,仅2节段CTA与DSA分级不符。结论 16排CT血管成像在评价腹主动脉及下肢动脉阻塞性病变方面与DSA结果基本一致,是一项高度准确的成像技术和非侵袭性检查方法。 |

| Objective To assess the diagnostic value of 16 slice multi-detector CT (MDCT) angiography in sclerosis or blocked disease of aorta and lower extremity arteries. Methods Twenty-six suspected patients with sclerosis or blocked disease of lower extremity arteries underwent 16 slice MDCT and 3D reconstruction. Fifteen cases underwent operation for artificial vessel or arterial stent employment 1-4 weeks after examination. Results All 494 segments in 26 cases of abdomial aorta and lower extremity arteries were counted. Eight remote end segments were not displayed well in volume rendering (VR). Severe constrictions were found in 97 segments, and 83 segments were totally blocked. Ninety-five segments detected by both DSA and MDCT, only 2 segments were different from DSA findings in grading. Re-examinations after operation showed pass-by vessel blocked up totally in one case, and narrowing in another case. Conclusion As an accurate and non-invasive angiographic technique, MDCT is as valuable as DSA in the assessment of sclerosing and occlusive diseases of abdominal aorta and lower extremity arteries. MDCT can be used as substitute for DSA. |
