Caesarean Hysterectomy

Caesarean hysterectomy (CH) is considered the gold standard for management of morbidly adherent placenta, now termed as placenta accreta spectrum (PAS). If bleeding is not controlled following removal of uterus, it is sometimes necessary to pack the pelvis and continue monitoring with correction of bleeding and physiological parameters in operating room and intensive care unit. This now comes under the damage control approach, being driven primarily by abnormal physiology rather than anatomical reconstruction. The pelvic packs are removed after about 48 hours. This retrospective study was done in patients with antenatal diagnosis of PAS who required CH, comparing those who required pelvic packing with those who did not. The variables compared were pre-operative (clinical and radiological), intra-operative (duration of surgery, blood loss and transfusion requirements of whole blood and blood products), and the final histopathological diagnosis. Outcome variables in terms of duration of hospital stay, re-admissions, re-laparotomy and complications were also compared. Over two years, three of eight patients with PAS required pelvic packing following CH. There were no differences between the two patient groups with any of the predictor variables or outcomes other than requirement of blood products. This suggests pelvic packing is a safe and efficacious procedure in intractable haemorrhage following CH for PAS. Pelvic packing needs greater awareness amongst obstetricians as the incidence of PAS is likely to increase.

Abstract Objectives We aimed to assess the performance of ultrasound (US) and magnetic resonance imaging (MRI) signs for antenatal detection of placenta accreta spectrum (PAS) disorders in women with placenta previa (placental edge ≤2 cm from the internal uterine orifice, ≥260/7 weeks’ gestation) with and without a history of previous Caesarean section. Methods Single center prospective observational study. US suspicion of PAS was raised in the presence of obliteration of the hypoechoic space between uterus and placenta, interruption of the hyperechoic uterine-bladder interface and/or turbulent placental lacunae on color Doppler. All MRI studies were blindly evaluated by a single operator. PAS was defined as clinically significant when histopathological diagnosis was associated with at least one of: intrauterine balloon placement, compressive uterine sutures, peripartum hysterectomy, uterine or hypogastric artery ligature, uterine artery embolization. Results A total of 39 women were included: 7/39 had clinically significant PAS. There were 6/18 cases of PAS with anterior placenta: hypoechoic space interruption and placental lacunae were the most sensitive sonographic signs (83%), while abnormal hyperechoic interface was the most specific (83%). On MRI, focal myometrial interruption and T2 intraplacental dark bands showed the best sensitivity (83%), bladder tenting had the best specificity (100%). 1/21 women with posterior placenta had PAS. There was substantial agreement between US and MRI in patients with anterior placenta (κ=0.78). Conclusions US and MRI agreement in antenatal diagnosis of clinically significant PAS was maximal in high-risk women. Placental lacunae on ultrasound scan and T2 intraplacental hypointense bands on MRI should trigger the suspicion of PAS.

Caesarean Hysterectomy

Background: In present scenario of increasing cases of previous caesarean section the diagnosis of Placenta accreta preoperatively is of great value to the attending obstetrician. This helps in preparing, counselling the patient and also in assembling a multidisciplinary team for effective peripartum clinical management of these patients to prevent maternal morbidity and mortality.Methods: One hundred patient with persistent placenta previa after 28 weeks gestation were screened by grey scale B mode sonography. In suspicious cases of placenta accreta, further assessment by colour Doppler ultrasound was done. The color doppler imaging (CDI) criteria used were - diffuse intra parenchymal placental lacunar flow, focal intra parenchymal placental lacunar flow, bladder-uterine serosa interphase hypervascularity, prominent sub-placental venous complex and loss of sub-placental vascular signal in areas lacking peripheral sub-placental hypoechoic zone. Patients were prospectively followed up till delivery and the CDI findings were analysed with reference to final diagnosis made during caesarean section.Results: Six of hundred patients exhibited characteristic CDI patterns highly specific for placenta accreta according to the criteria used. In all 6 patients, morbidly adherent placenta was present intraoperatively. The sensitivity and specificity of CDI in the diagnosis of placenta accreta in presentstudy was 100%. Caesarean hysterectomy was required in five patients. Patients with CDI features of lacunar flow had higher incidence of blood loss, transfusion requirements and need for caesarean hysterectomy compared to patients with nonlacunar flow. The remaining 94 patients with placenta previa, not suspicious for placenta accreta on sonography underwent uncomplicated caesarean section.Conclusions: The use of CDI along with conventional grey-scale sonography improves the diagnostic accuracy for prediction of placenta accreta in patients with persistent placenta previa.

Caesarean Hysterectomy

Placenta accreta spectrum and placenta praevia are a significant cause of obstetric haemorrhage, maternal morbidity and mortality worldwide. We report a novel surgical technique, which pre-emptively and prophylactically reduces intrapartum bleeding during caesarean sections for these conditions and hence reducing the risk for a caesarean hysterectomy. This technique is particularly useful in low resource healthcare settings where interventional radiology is not readily available and where the woman is keen on uterine preservation. In this report we present the surgical and clinical outcomes of a case series of 16 patients on whom this technique was piloted demonstrating its feasibility and safety.

Background: Aim of the study was to evaluate the outcome of pregnancy in placenta accrete spectrum in third trimester pregnancy at tertiary care centreMethods: This hospital based retrospective study was carried out from 2017 to 2019.  The case records of all women identified as placenta accrete spectrum from the hospital registers were retrieved. A total of 166 patients with the diagnosis of placenta accrete spectrum were included in the study.Results: The incidence of morbidly adherent placenta is 5 per 10,000 deliveries with mean age being 32.4±4.2 (23-39) years. and showed its relation with risk factors such as previous caesarean section (CS), placenta praevia and multiparity. The mean duration of MICU stay in placenta previa was 6.7±1.9 days (range 2-12 days). With complications in 18 cases of which urinary bladder injury (3%), infection (9%), PPH and coagulopathy (4.2%). The placenta was removed successfully in 141 while 25 cases had caesarean hysterectomy (2.4%). In total 166 cases 26 (16.8%) cases are intrauterine device (IUD) and still births. 5 (3%) cases are very low birth weight, 24 cases (14.5%) are low birth weight babies, 76 (45.8%) cases had neonatal intensive care unit (NICU) admissions followed by 10 (6%) cases with <5 APGAR score.Conclusions: Placenta accreta spectrum can be identified antenatally with a high index of suspicion in the presence of known risk factors and proper radiological studies, allowing for planned attempts to avoid life-threatening haemorrhage and caesarean hysterectomy.

Abstract Objectives To assess the applicability of a standardized multidisciplinary protocol for managing placenta accreta spectrum (PAS) disorders and its impact on the outcomes. Methods We compared patients with PAS manage by a standardized multidisciplinary protocol (T2) to historic controls managed on a case-by-case basis by individual physicians between (T1). The primary outcome is composite maternal morbidity. Secondary outcomes were the rates of surgical complications, estimated blood loss, number of blood products transfused, intensive care unit admissions, ventilator use, and birth weight. Multivariate logistic analysis was used to identify independent predictors of composite maternal morbidity. Results During T1 and T2, we managed 39 and 36 patients with confirmed PAS, respectively. During T2, the protocol could be implemented in 21 cases (58%). Compared to T1, patients managed during T2 had 70% less composite maternal morbidity (95% CI: 0.11–0.82) and lower blood loss (median, 2,000 vs. 1,100 mL, p=0.008). Also, they were 68% less likely to require transfusion of blood products (95% CI: 0.12–0.81; p=0.01), including fewer units of packed red blood cells (median, 2 vs. 0, p=0.02). Management following the protocol was the only independent factor associated with lower composite maternal morbidity (OR: 0.22; 95% CI: 0.05–0.95; p=0.04). Selected maternal and neonatal outcomes were not different among 12 and 15 patients with suspected but unconfirmed PAS disorders managed during T1 and T2, respectively. Conclusions Most patients can be managed under a standardized multidisciplinary protocol for PAS disorders, leading to improved outcomes.

Objective: Compare maternal and perinatal outcomes between emergency and elective caesarean-hysterectomy for placenta accreta spectrum (PAS) disorders managed by a multidisciplinary team. Design and setting: Single-centre retrospective cohort study Population: 125 cases of antenatally suspected and pathologically confirmed PAS disorder. Methods: Maternal and perinatal outcomes were analyzed. Multivariate logistic regression was used to test associations, adjusting for potential confounders. Survival curves exploring risk factors for emergency delivery were sought. Main Outcome Measures: Maternal outcomes including hemorrhagic morbidity, operative complications. Perinatal outcomes included gestational age at delivery, birthweight, Apgar scores and perinatal death. Results: 25 (20%) and 100 (80%) patients had emergency and elective delivery, respectively. Emergency delivery had a higher estimated blood loss (median IQR 2772 [2256.75] vs. 1561.19 [1152.95], p<0.001), with a higher rate of coagulopathy (40 vs. 6%; p<0.001) and bladder injury (44 vs. 13%; p<0.001). Emergency delivery was associated with increased rates of blood transfusion (aOR 4.9, CI95% 1.3-17.5, p=0.01), coagulopathy (aOR 16.4, CI95% 2.6-101.4, p=0.002) and urinary tract injury (aOR 6.96, CI95% 1.5-30.7, p=0.01). Gestational age at delivery was lower in the emergency group (mean SD 35.19 [2.77] vs. 31.55 [4.75], p=0.001), no difference in perinatal mortality was found (aOR 0.01, CI95% <0.001-17.5, p=0.53). A sonographically short cervix and/or history of APH had an increased cumulative risk of emergency delivery with advancing gestational age. Conclusions: Patients with PAS disorders managed in a tertiary centre by a multidisciplinary team requiring emergency delivery have increased maternal morbidity and poorer perinatal outcomes than those with elective delivery.
