Table 4:

Evaluation of the possible viability of the kidney with ARVD following revascularization.

Variable	Likely to benefit	Unlikely to benefit
RAS degree	>70%	<50%
Kidney length (cm)	>8 cma	<7 cm
Renal resistive index	<0.8	>0.8
Cortical thickness	Cortex distinct, e.g. >0.5 cm	Loss of corticomedullary differentiation, no cortex

^aThe suggested kidney length thresholds are relevant to individuals with average body habitus (i.e. body surface area ≈1.73 m²). For patients with very high or very low body mass, possibly consider the ratio of kidney length to the patient's body mass index or body surface area to approximate kidney size in relation to patient's body habitus.
