Here we report a rare case of neonatal arterial ischemic stroke after fetal traumatic head depression caused by functional cephalopelvic
disproportion due to a "long pelvis"  during a precipitate delivery in 2004.
62% of patients who received blood transfusion were emergency cases following fetal distress or failed progress in labor due to malpresentation, cephalopelvic
disproportions or uterine dystocia.
On the other hand, women who had a prior cesarean delivery for cephalopelvic
disproportion or failure to progress have been shown to have lower TOLAC success rates ranging from 50% to 67%.
Measures should be taken to reduce associated factors such as cephalopelvic
disproportion which mainly results from malnutrition and pregnancy at an early age.
In group two, one woman had a cesarean section for cephalopelvic
disproportion, and six women underwent instrumental vaginal delivery (p=0.
Patients with cardiovascular disease, bronchial asthma, renal or hepatic disorders, cephalopelvic
disproportion, low-lying placenta, acute local cervical lesion, and previous lower segment cesarean section or any scar over the uterus were excluded from the study.
An increased rate of caesarean section is also reported which could be due to fetal distress, malpresentations and cephalopelvic
disproportion due to undiagnosed pelvic neurofibromas and pelvic contractures including cases of kyphoscoliosis affecting the lower spine (sequelae of NF1) [6, 26].
Her first cesarean section was done for Cephalopelvic
1 Recurrent causes like cephalopelvic
disproportion need repeat lower segment caesarean section while non recurrent causes like placenta previa may not need repeat caesarean section but have increased chances of vaginal delivery.
Indications for cesarean delivery were prior cesarean section (76/141), cephalopelvic
disproportion (36/141), breech presentation (17/141), and fetal distress during labor (12/141).
Nonpreventable complications include breech delivery, cephalopelvic
disproportion, cord prolapse, placenta previa, and abruptio placenta.
