Fig. 2From: Lower limb ischemia caused by resuscitative balloon occlusion of aortaIllustration of an artery model with in situ sheath. The size of the femoral artery in our patient was 5.6Â mm. This figure illustrates a 5.6-mm artery model with sheath sizes of 7-Fr and 12-Fr. The proportion of cross-sectional vascular area with the use of 12-Fr sheath reduces by 50 % of the original cross-sectional areaBack to article page
