AB - <p style="text-align: justify;">We study the backward self-similar solution of Leray’s type for compressible Navier-Stokes equations in dimension two. The existence of weak solutions is established via a compactness argument with the help of an higher
integrability of density. Moreover, if the density belongs to $L^∞(\mathbb{R}^2)$ and the
velocity belongs to $L^2(\mathbb{R}^2),$ the solution is trivial; that is $(\rho,\mathbf{u})=0.$</p>
