(A) Line drawing of an ER-REBOA catheter. Length ‘a’ is the intended working length, between radio-opaque markers, which is normally up to 37 mm. Length ‘b’ is the entire length of the balloon, including the ‘shoulders’, which are not intended to be in apposition with the vessel wall. Length ‘c’ is the diameter of the balloon. (B) Zone 3 resuscitative endovascular balloon occlusion of the aorta (REBOA) demonstrating appropriate balloon inflation. Note: rounded shoulders and a footprint of 31.4 mm, well within the intended working length of 37 mm. (C) Zone 3 REBOA demonstrating overinflation and elongation, with a balloon footprint of 51.1 mm. Same scale as (B).

Two images demonstrating the propensity for the aorta to rupture in the longitudinal direction.

Maximal circumferential stretch ratios compared with baseline aortic diameter. Linear regression, R2=0.72; P<0.001.
- Figure 4
(A) Circumferential compliance ratio compared to aortic diameter at maximum balloon inflation (24 mL, expected balloon diameter is 32 mm). R2=0.85. (B) Longitudinal compliance ratio compared with aortic diameter when balloon is inflated with 8 mL (expected balloon diameter is 20 mm). R2=0.85.
