Introduction: The ischaemic disorders as a complication of intra-aortic balloon pump counterpulsation (IABP) could be deleterious in critically ill patients with myocardial failure and cardiogenic shock. Tis study is a pilot to predict the length of the descending aorta to select the optimum IABP size for Asian patients. Methods: The somatometric features from 80 Chinese patients were used: gender, age, height, body mass index, body surface area, trans-pyloric plane. Moreover, the aortic length from the origin of left subclavian artery to the orifice of the celiac trunk (LSA-CT) measured from tomographic scan examination. The variables to predict the length from the LSA-CT were studied in four types of predictive statistical analysis: nonlinear regression analysis, tree model, linear regression, and loglinear regression. The model was defined by obtaining the R square. Results: Tere were 59 males (mean age 53.9 years SD 13.2, height 170.8cm SD 4.0) and 21 females (mean age 58.7 years SD 7.8, height 160.2 cm SD 6.8). LSA-CT distance was found to be 279.5 SD 31.34 mm. The length of distance from the jugular notch to trans-pyloric plane was 273.8cm SD 12.5. The body mass index was 25.6 Kg/m2 SD 3.8 and the body surface area 1.8 m2 SD 0.1. The tree model for predicting the distance to the left subclavian artery to the celiac axis was chosen due to obtained an R2 square of 0,829. The comparison between the tomographic values and results of the tree model was realized with a nonparametric test. Wilcoxon signed-rank test showed that the values of computed tomograhy scan did not show a statistically significant difference with the results of the tree model (Z = -0.827 p =0.408). Conclusion: The tree model for predicting the distance from the left subclavian artery to the celiac trunk, could be an accurate guide to choosing an adequate catheter length of intra-aortic balloon pump counterpulsation in Asian patients.
