study will be carried out on patients with placenta accreta spectrum having done uterine conservation and recording immediate outcome of conservation regarding success of the procedure, amount of blood loss and amount of blood transfused and followed up to check the return of menses, any uterine abnormalities by ultrasound or hysteroscopy especially isthmocele and intrauterine synechia.
After institutional review board approval and written informed consent, recruited cases will be subjected to the following:
Data registration including:
Anthropometry including weight, height, and body mass index (BMI) before pregnancy and at the time of operation.
General examination including vital signs, and signs of any associated problems.
Routine laboratory investigations with particular emphasis on complete blood count, Coagulation profile and including blood glucose level, renal and liver function tests.
Detailed sonographic examination to evaluate fetal biometry, and wellbeing rule out exclusion factors, and confirm diagnosis of PAS and assess the degree of invasion, and its severity using both trans-abdominal transducer with frequency of 2-5 megahertz (MHZ) and trans-vaginal transducer with frequency of 4-10 MHZ.
Intraoperative details will be documented. Follow up of patients will be recorded. Sample size was calculated by estimating a single proportion distribution at a significance level of 0.05.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| pregnant women with placenta accreta spectrum | Experimental | Bladder will be dissected and mobilized down to the vagina after skeletonization and securing of bridging vessels either by electro-coagulation or ligation. Uterus will be incised 5mm above the placenta bulge, delivering the fetus followed by Carbetocin 100 microgram /1 ml intravascular. Repair of the uterine wall defect will be done. If extrauterine bleeding is excessive we may revert to internal iliac artery ligation followed by insertion of intra-peritoneal drain and regular abdominal wall closure. After 3 months from delivery, ultrasound with different modalities will be done to all patients and outpatient hysteroscopy if symptomatic patients or with abnormal sonography. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| closure of the uterine wall defect | Procedure | Uterine exteriorization followed by pealing of amniotic membranes to reach an accessible pole of the placenta to detect a plan of cleavage behind it. The independent hand of the surgeon passed through the previous plan from points of least resistance to high resistance. The defect will be repaired from the inner aspect of the uterus via running sutures using Vicryl (1-0) on a round needle, 45mm. the suture will pass from one edge to hitch the bed and pass to the other edge till we completely close the defect subsequently, controlling the bleeding. Uterine scar closure by running sutures in two layers, where the first layer compresses the placental bed defect externally. |
| Measure | Description | Time Frame |
|---|---|---|
| date of resumed menses | calculate the duration from surgery until menses returns | from 2 weeks to 6 months after surgery |
| menstrual abnormalities | record type of menstrual abnormalities if present such as amenorrhea, oligomenorrhea and dysmenorrhea | from 2 to 6 months after surgery |
| abnormal uterine bleeding | record the presence of abnormal uterine bleeding after the return of menses such as intermenstrual bleeding, menorrhagia | from 2 to 6 months after surgery |
| pelvic pain | record the presence of pelvic pain and its duration | from 2 to 6 months after surgery |
| isthmocele | trans-vaginal and trans-abdominal ultrasound will be done to record the presence of isthmocele, its shape and ratio between residual myometrium and total myometrium | from 3 to 6 months after surgery |
| intrauterine adhesions | outpatient hysteroscopy will be done to symptomatic patients after consent in order to check uterine cavity recording the presence of intrauterine adhesions, and categorization of adhesions according to american fertility society into mild, moderate and severe | from 3 to 6 months after surgery |
| puerperal blood loss | recording the duration of blood loss during puerperium and average number of tampons changed per day |
| Measure | Description | Time Frame |
|---|---|---|
| operation time | recording total time of the surgery | intraoperative |
| repair time | recording length of defect repair from placental separation until uterine wall closure |

| ultrasound | Diagnostic Test | Before the procedure transabdominal and transvaginal ultrasound will be done to diagnose PAS and to map the uterine wall defects. After 3 months,Transabdominal and transvaginal ultrasound with different modalities to assess the uterine wall, the cavity, endometrium, myometrium and the cervix. Isthmocele will be defined as a defect at uterine wall where residual myometrium thickness and ratio between residual myometrium and total myometrium thickness will be measured and recorded. The shape of the isthmocele will be also recorded. |
|
| outpatient hysteroscopy | Diagnostic Test | Office hysteroscope will be done after patient consent to evaluate the uterine cavity if the patient is symptomatic or with abnormal sonography. It will be performed in the proliferative phase of the menstrual cycle. Non-steroidal anti-inflammatory will be given one hour before the procedure, then the patient will be in lithotomy position. Following aseptic rules, the rigid 4 mm hysteroscope will be inserted into the uterus through the cervix without using speculum nor tenaculum. Any pathology will be identified, and data will be recorded. |
