Answer:
that's correct, but not all ventral herniae are incisional herniae, and even though some none-ventral herniae ( i.e. inguinal , femoral or umbllical ) are incisional in its pathophysiology ( i.e. technical failure and/or wound healing disturbance ) , yet they are not considered or labelled as incisional ones, simply because they are none-ventral ones ( i.e. they are "natural anatomical weakness points"), instead they are labelled "recurrent" ( i.e. recurrent inguinal or femoral or umbllical herniae ).
