INFRARENAL ANGULATION FOR PATIENTS IN THE NORMAL DIAMETER (ND) GROUP: 31.7 DEGREES +/- 19.4 DEGREES. INFRARENAL ANGULATION FOR PATIENTS IN THE LARGE DIAMETER (LD) GROUP: 21.5 DEGREES +/- 12.1 DEGREES. SUPRARENAL ANGULATION FOR PATIENTS IN THE NORMAL DIAMETER (ND) GROUP: 24.8 DEGREES +/- 18.9 DEGREES. SUPRARENAL ANGULATION FOR PATIENTS IN THE LARGE DIAMETER (LD) GROUP: 16.5 DEGREES +/-15.8 DEGREES. RENAL OCCLUSIVE DISEASE FOR PATIENTS IN THE NORMAL DIAMETER (ND) GROUP: 18. RENAL OCCLUSIVE DISEASE FOR PATIENTS IN THE LARGE DIAMETER (LD) GROUP: 8. 1 PATIENT (NORMAL DIAMETER (ND) GROUP) HAD SMA STENT OCCLUSION THAT REQUIRED REINTERVENTION.
