Abstract:

Background. To report the lengths of key torso vascular and to develop regression models that will predict these lengths, based on an external measure of torso height EMTH, sternum to pubis in the development of a fluoroscopy free balloon occlusion system for hemorrhage control. Methods. We conducted a prospective, observational study at a Combat Support Hospital in Southern Afghanistan using adult male patients undergoing computed tomography CT. EMTH was recorded using a tape measure and intra arterial distance was derived from CT imaging. Regression models to predict distance from the common femoral artery CFA into the middle of aortic zone I left subclavian artery to celiac trunk and zone III infrarenal aorta were developed from a random 20 of the cohort and validated by the remaining 80. Results. Overall, 177 male patients were included with a median interquartile range IQR age of 23 8 years. The median IQR lengths of aortic zone I and III were 222 24, 31 9, and 92 15 mm. The mid zone distance from the left and right CFA to zone I were 423 27 and 418 29 and for zone III 232 21 and 228 22. Linear regression models demonstrated an accuracy between 99.3 to 100 at predicting the insertion distance required to place a catheter within the middle of each aortic zone. Conclusion. This study demonstrates the use of morphometric analysis in the development of a fluoroscopy free balloon occlusion system for torso hemorrhage control. Further study in a larger population of mixed gender is required to further validate insertion models.
