Abstract：Objective To investigate the feasibility and advantages of heated contrast medium in digital subtraction angiography(DSA) of lower extremity arteries. Methods A total of 47 patients with arteriosclerosis occlusion of lower extremity were enrolled,
and DSA was performed with normal temperature contrast agent. Then, due to pain or pain aggravation, the contrast was not good and the DSA was performed with heating contrast agent. Results The incidence of pain in the heating group was 27.66% lower than
that in the normothermic group, while the incidence of moderate/severe pain decreased by 34.04%. The incidence of severe motion artifacts also decreased by 19.14%, while the clearness of tibiofibular segment and foot vessels increased by 23.32% and 24.69%.
In addition, the emptying time of popliteal segment, tibiofibular segment and foot contrast media was also shortened by (3.33 ±1.99) s, (8.71 ±2.67) s and (9.34 ±2.29) s respectively. The difference between the two groups were statistically significant (P<0.05). Conclusion Lower extremity arteriography is performed on patients with arteriosclerosis obliterans by using 37℃ heating contrast agent, which can promote contrast empty, decrease contrast agent stimulation, reduce or eliminate pain in patients, and improve image quality.
