Is there an equivalent in T-SQL to C#'s "throw;" to re-throw exceptions?

The title really is the question for this one: Is there an equivalent in T-SQL to C#'s "throw;" to re-throw exceptions?

In C# one can do this:

try
{
    DoSomethingThatMightThrowAnException();
}
catch (Exception ex)
{
    // Do something with the exception
    throw; // Re-throw it as-is.
}

Is there something in T-SQL's BEGIN CATCH functionality that does the same?
