Abstract：Objective To analyze the anatomical features of inferior mesenteric artery (IMA) and explore the optimal proposal of the selective IMA intubation. Methods 132 cases (median age 59.5 years old) whose superior mesenteric artery and IMA showed normal on enhanced CT were selected. The diameter of IMA opening, vertical lengths from the IMA openning to the common iliac artery bifurcation, lumbar plane corresponding to the IMA openning, and angle of iliac artery bifurcation were compared between male and female patients. Eighty patients underwent selective IMA intubation, among 40 of the 80 cases looped C2 catheter was used , and non-looped C2 catheter was used in the another 40 cases. Results The diameter of IMA opening and the vertical lengths from common iliac artery bifurcation were larger in male than in female patients (31.5±5.5 mm vs. 27.2±4.7 mm, P<0.05;42.9±6.7mm vs.40.1±7.8mm, P<0.05 respectively).The differences in the opening position of IMA and angle of iliac artery bifurcation did not differ between male and female patients (P>0.05). Forty cases successed by using the techniques of looped C2 catheter.Twenty-five cases successed and Fifteen cases failed (male 4 cases, female 11 cases) by using the techniques of non-looped C2 catheter. There was statistical significance in success rate between the two groups (P<0.01). Conclusion IMA has a smaller diameter and low opening position. Selectively catheterization by using C2 catheter looping technology can improve the success rate.
