How safe is vbac for the mother and fetus? | J fam Pract | 55 | 149 | 2006 | |
| Ghaffari (Qatar) |
Safety of VBAC | Int J Gyn Ob | 92 | 38 | 2006 | 702 patients with Hx of one PCS, divided into group with no previous vaginal delivery and those with a previous vaginal delivery (62%) Found that vaginal delivery occurred more often in those with no Hx of previous vaginal delivery (87.7% versus 79.2%). Conclusion: these findings indicate that women who have had a CS should strongly consider natural delivery for subsequent pregnancies. |
| Gonen (Israel) |
Results of a well defined protocol for a TOL after PCS | OG | 107 | 240 | 2006 | Described their management protocol (one PCS, spontaneous labor, Vtx, no prostaglandins, CS if cervix is unripe). Compared 841 women attempting VBAC versus 467 had planned ERCS. There was one uterine rupture found 18 hours after delivery. Conclusion: With their well-defined protocol, a TOL seems to be a safe as planned CS and the length of stay is shorter. |
| Pare (U of Penn) |
VBAC versus elective repeat CS: assessment of maternal downstream health outcomes | BJOG | 113 | 75 | 2006 | Conc: Long-term reproductive consequences of multiple CS should be considered when making policy decisions regarding the risk/benefit ratio of VBAC. |
| Yeh (U at Buffalo) |
Temporal trends in the rates of trial of labor in low risk pregnancies and their impact on the rates and success of VBAC | AJOG | 194 | 144 | 2006 | The national rate of VBAC has decreased by 55% between 1996 and 2002. Review of 11,446 patients who had a previous Cesarean section looking at trial of labor, VBAC attempts and VBAC success. Found that the success rates were similar during this time but that fewer attempted VBAC suggesting that the decline in VBAC may be due to a decline in trial of labor attempts and not ot a change in success rates. |

Delivery of dead fetus from inside urinary bladder with uterine perforation: case report and review of the literature | Urology | 65 | 797 | 2005 | Case report |
| Baskett (Canada) |
Severe obstetric maternal morbidity: a 15-year population based study. | JOG | 25 | 7 | 2005 | Looked at 159,896 deliveries and looked for indications of severe maternal morbidity (> 5 blood transfusions, emergency hysterectomy, uterine rupture, eclampsia and ICU admission) There were 313 patients with those markers (257 had one, 42 had 2 12 had 3 and 2 had four) 119 cases of > 5 blood transfusions, 88 emergency hysterectomies, 49 uterine rupture, 46 cases of eclampsia and 83 admissions to ICU. |
| Buhimschi (Yale) |
Rupture of the uterine scar during term labor: contractility or biochemistry? | BJOG | 112 | 38 | 2005 | Uterine rupture occurs more frequently in women who have been given prostaglandins, hypothesize that similar to the cervix, prostaglandins induces biochemical changes in the uterine scar favoring dissolution, predisposing the uterus to rupture at the scar of the lower segment. Compared the location of the rupture of the scar in prostaglandins versus elsewhere without prostaglandins. Found that women treated with prostaglandins tend to rupture at the location of the previous scar more frequently than women in the oxytocin group whose rupture tended to occur remote from their old scar. |
| Bujold (Wayne State) |
The role of maternal body mass index in outcomes of VBAC. | AJOG | 193 | 1517 | 2005 | 8580 pats with a PCS, 21.7% had an elective repeat CS, 78.3% had a trial of labor. Found that maternal body mass index correlated inversely with the rate of successful VBAC but not with the rate of uterine rupture. |
| Cahill (U of Penn) |
VBAC attempt in twin pregnancies: is it safe? | AJOG | 193 | 1050 | 2005 | Multicenter, retro, 25,005 patients with at least one PCS, 535 had twin pregnancies. Found patients with twins were less likely to attempt VBAC but of those that did try, there was no increase in failure, rupture of uterus or major maternal morbidity. |
| Casanova (U of Penn) |

| Cheung (Toronto) |
Sonographic measurement of the lower uterine segment thickness in women with previous CS | JOG | 27 | 674 | 2005 | US evaluation of the LUS in 102 patients with one or more PCS. The mean sonographic thickness was 1.8 mm Two women had uterine rupture, both of which had a lower uterine segment of < 1mm. |
| Cleary- (Goldman Columbia) |
Previous CS: understanding and satisfaction with mode of delivery in a subsequent pregnancy in patients participating in a formal VBAC counseling program | A J Peri | 22 | 217 | 2005 | Survey of patients participating in a formal VBAC educational program. Looked at those who had a successful VBAC, those who chose elective CS and those who had a CS after labor. The most satisfied patients were those who had a successful VBAC, most women valued the opportunity to attempt a VBAC regardless of outcome. |
| Coassolo (U of Penn) |
Safety and efficacy of VBAC at or beyond 40 weeks gestation | OG | 106 | 700 | 2005 | Retro, 11,587 in the cohort attempting VBAC. Found that women past 40 weeks were more likely to have a failed VBAC. (31% versus 22%). Conc: women beyond 40 weeks gestation can safely attempt VBAC although the risk of VBAC failure is increased. |
| Coleman (ACOG) |
VBAC: practice patterns of ObGyn | JRM | 50 | 261 | 2005 | Survey in July 2003 of ACOG fellows by random sample. 49% said that they were performing more CS than they did 5 years earlier. The reasons given were risk of liability and patient preference. More than 25% of physicians reported that they practiced in hospitals that do not follow the ACOG guidelines. 61% felt competent in determining which patients will have a successful VBAC. |
| Diab (Yemen) |
Uterine rupture in Yemen | Saudi Med J | 26 | 264 | 2005 | Retro, 5 year all cases of a patient with a ruptured uterus (5547 deliveries, 60 cases of ruptured uterus, 1.1%) 43 cases happened in an unscarred uterus (71.7&) and 17 (28.3%) in a patient with PCS. 93.3% had no prenatal care, 95% presented to the hospital after a long period of obstructed labor. Grand-multiparity was encountered in 69.8% of the no PCS group and 41.2% of the PCS group. |
| Dunn (Dublin) |
Comparison of maternal satisfaction following vaginal delivery after CS and CS after previous vaginal delivery. | Euro J Ob Gyn Reprod Biol | 121 | 56 | 2005 | Questionnaire, found maternal satisfaction with vaginal delivery was high. Those who experienced both preferred a vaginal birth. |
| Ezegwui | Trends in uterine rupture in Enugu, Nigeria | JOG | 25 | 260 | 2005 | Retro, 4,333 deliveries with incidence of uterine rupture of 1 in 106 deliveries. Findings included multips, labor < 24 hours and 22% had Pitocin given. 68% of the uterine ruptures had a Hx of a previously scarred uterus and 53% of those were in the lower uterine segment. Perinatal mortality was high |
| Gochnour (Utah) |
The Utah VBAC study | Matern Child Health J | 9 | 181 | 2005 | Examined the effects of ACOG's new guidelines on physicians VBAC practices in Utah via questionnaire. Found the 97% of obstetricians and 79% of family practitioners were aware of guidelines. 45% of all physicians reported a decline in VBAC in the preceding 12 months. 87% had physician immediately available (100% of urban, 88% of suburban and 76% of rural) Found that many rural hospitals are unable to comply with number 5 of recommendations. |
| Godall (U of Chicago) |
Obesity as a risk factor for failed trial of labor in patients with previous cesarean delivery | AJOG | 192 | 1423 | 2005 | Review of all singleton deliveries with previous CS, 1998-2002, stratifying by body mass index (BMI). Normal BMI <25, overweight BMI 25-29.9, obese BMI 30-39.9 and morbidly obese BMI >40. Conclusion: obesity is an independent risk factor for failed TOL in patients with a previous CS. |
| Guise (Oregon) |
Evidence-based VBAC | Best Pract Res Clin Ob Gyn | 19 | 117 | 2005 | Chapter review of the literature about the rising risks of VBAC, patient and management factors that may alter risk, and discusses ongoing research as well as suggestions for improving future research |

| Hicks | Systematic review of the risk of uterine rupture with the use of amnioinfusion after PCS. | South Med J | 98 | 458 | 2005 | Medline, Cochran searches. Conclusion: the use of amnioinfusion in women with PCS who are undergoing a TOL may be a safe procedure, but confirmatory large, controlled prospective studies are needed before definitive recommendations can be made. |
| Hoffman (Delaware) |
Uterine rupture in patients with prior CS: the impact of cervical ripening | OGS | 60 | 22 | 2005 | Retro, 972 VBAC attempts, 72% success. There were 33 uterine ruptures at the site of previous cesarean delivery (3.4%). All but 5 ruptures were symptomatic. Induction was more frequent in the uterine rupture group and they were much more likely to have had cervical ripening. The odds ratio for cervical ripening and uterine rupture was 3.93. The risk/benefit ratio would seem to discourage cervical ripening. |
| Honig (Germany) |
Placenta percreta with subsequent uterine rupture at 15 weeks gestation after two previous CS | JOG | 31 | 439 | 2005 | Case report |
| Juhasz (Columbia) |

Conc: excessive weight gain during pregnancy and obesity both decrease the likelihood of VBAC success. |
| Kayani (Liverpool) |
Uterine rupture after induction of labor in women with PCS | BJOG | 112 | 451 | 2005 | Retro, 5 year, 205 patients had their labor induced with Hx. of one PCS. There were 4 cases of uterine rupture and one of dehiscence. 2 babies were profoundly acidotic at birth but all five neonates were healthy when discharged. Conclusion: In women with PCS and no vaginal deliveries, induction of labor carries a relatively high risk of uterine rupture/dehiscence despite all precautions, including IUPC. |
| Kenton (Loyola) |
Repeat CS and primary elective CS: recently trained ObGyn practice patterns and opinions | AJOG | 192 | 1872 | 2005 | Questionnaire of ObGyn attending 2 review courses. Found that 2/3 of recent graduates are willing to perform an elective CS to prevent pelvic floor injury. Most offer VBAC |

Conclusion: Previous vaginal delivery including previous VBAC is the greatest predictor for successful TOL. Previous indication as dystocia, need for labor induction or maternal BMI > 30 significantly lowered success rates. |
| Latendresse (Salt Lake City) |
A description of the management and outcomes of VBAC in the homebirth setting | J Midwifery Womens Health | 50 | 386 | 2005 | Intended home births of 57 patients attempting VBAC. 93% had a spontaneous birth, 97% of those with a previous successful VBAC were again successful, 88% of those without a previous successful VBAC also delivered vaginally. There were no uterine ruptures, there was one fetal demise in a postdate pregnancy with meconium. Conclusion: Given what is known, VBAC is not recommended in the home birth setting. |
| Lim (Netherlands) |
Pregnancy after uterine rupture: a report of 5 cases and a review of the | OGS | 60 | 613 | 2005 | Case report of 5 pregnancies after a uterine rupture. All were delivered via Cesarean and there were no repeat ruptures. |
| Macones (U of Penn) |
Maternal complications with VBAC: a multicenter study | AJOG | 193 | 1656 | 2005 | Case control, found that the incidence of uterine rupture was 9.8/1,000; prior vaginal delivery was associated with a lower risk 0.4/1,000. Prostaglandins alone were not associated with an increase in uterine rupture, sequential of prostaglandin and Pitocin was associated with a rupture rate of 3/1,000. Suggest that inductions requiring sequential agents be avoided. |
| Maconnes (U of Penn) |
Ob outcomes in women with 2 prior cesarean deliveries: is VBAC a viable option? | AJOG | 192 | 123 | 2005 | Compared all patients with 1 versus 2 prior CS attempting VBAC. There were 20,175 patients attempting VBAC after 1 prior CS and 3,970 attempting VBAC after 2 PCS. The rate of success was similar (75.5% versus 74.6%) They found that the risk of morbidity was higher in those attempting VBAC after 2 PCS but that the absolute risk remains low. (Adjusted odds ration 1.61 versus 2.26) |

| Phipps (Brown) |
Risk factors for bladder injury during CS | OG | 105 | 156 | 2005 | 42 bladder injuries amongst 14,757 CS. Found PCS more prevalent than controls and found an adjusted risk for bladder injury associated with PCS 3.83. |
| Pinette (Maine) |
VBAC rates ae declining rapidly in the rural state of Maine | OGS | 60 | 219 | 2005 | The rate of CS has risen from 5.5% in 1970 to 24.7% in 1986. Retro review of delivery records for the state of Maine 1998 to 2001 after ACOG VBAC recommendations. Found a marked drop in VBAC rates in rural hospitals with an overall decrease of 56%. |
| Quinones (U of Penn) |
The effect of prematurity on VBAC: success and maternal morbidity | OG | 105 | 519 | 2005 | Compared VBAC success and uterine rupture rates between preterm and term gestations in women with Hx of PCS. 20,156 patients with Hx of PCS, 12,463 attempted VBAC. The VBAC success rate for term gestation was 74% and for preterm gestation was 82%. There may be less uterine rupture in the preterm group. |
| Richardson (U of W Ontario) |
The impact of labor at term on measures of neonatal outcome | AJOG | 192 | 219 | 2005 | Compared neonatal outcome in planned CS, VBAC and normal deliveries. Found that all three had a low level of severe morbidity mortality however VBAC had an increased labor-related severe morbidity/death. |
| Rochelson (Manhassat) |
Previous preterm CS: identification of a new risk factor for uterine rupture in VBAC candidates. | J Mat Fet Meo Med | 18 | 339 | 2005 | Retro chart review of pts with TOL after PCS looking at gestational age when CS was done. Found 25 uterine ruptures and the risk was higher with a preterm cesarean section. Conclusion: an underdeveloped lower uterine segment in the preterm uterus represents a risk for later rupture. Even if the incision is transverse. |
| Shorten (Australia) |
Making choices for childbirth: a randomized controlled trial of decision-aid for informed birth after cesarean. | Birth | 32 | 252 | 2005 | Prospective, multicenter randomized controlled trial of 227 pregnant patients with Hx of PCS. One group given a decision-aid booklet describing the risk and benefits of elective repeat CS versus VBAC. Conclusion: a decision-aid for women facing choices about birth after CS is effective in improving knowledge and reducing decisional conflict. However, little evidence suggested that this process led to an informed choice |
