A previous classical or T-incision during a cesarean delivery can indeed lead to an increased risk of uterine rupture in subsequent pregnancies. Classical incisions are made vertically on the uterus and involve cutting through the muscle layers, which can compromise the structural integrity of the uterine wall. If a woman attempts a vaginal birth after cesarean (VBAC) following such an incision, the weakened area may not withstand the contractions of labor, leading to a potential rupture. This risk is significant enough that many practitioners recommend against attempting a vaginal delivery in women with this type of surgical history, emphasizing the importance of recognizing the increased danger associated with classical incisions.

On the other hand, a T-incision is similarly classified as a higher risk incision compared to the more common low transverse incision. The structural compromise from these types of incisions makes it crucial for healthcare providers to evaluate the suitability of labor for these patients carefully.
