We prove some triviality results for reduced Whitehead groups and reducedunitary Whitehead groups for division algebras over a henselian discretevaluation field whose residue field has virtual cohomological dimension orseparable dimension $\le 2$. These results are applied to show strongapproximation for isotropic absolutely almost simple simply connected groups oftype A. In particular, such a group defined over the function field of anonreal curve $C/k$ satisfies strong approximation if the base field $k$ is anumber field, a $p$-adic field, $\mathbb{C}(\!(t)\!)$ or a two-variablefunction field over $\mathbb{R}$.
