Kontinuitätssatz

Theorem.

$G\subset{\mathbb{C}}^{n}$ is pseudoconvex if and only if for any family of closed analytic discs $\{d_{\alpha}\}_{\alpha\in I}$ in $G$ with $\cup_{\alpha\in I}\partial d_{\alpha}$ being a relatively compact set in $G$ then $\cup_{\alpha\in I}d_{\alpha}$ is also a relatively compact set in $G$ .

This is the analogue of one of the definitions of a convex set. Just replace pseudoconvex with convex and closed analytic discs with closed line segments.
