Placenta Accreta
Conditions
Brief summary
This study will be conducted on (100) pregnant women diagnosed as placenta previa by ultrasonography and are candidates for either emergency or elective repeated cesarean section or hysterectomy (if the diagnosis of placenta accreta is confirmed). All of those patients are presenting during the period of may 2018 to july 2018 to Kasr-Al Ainy Obstetrics outpatient clinic or casualty department during their 3rd trimester. All of them will be assorted according to certain inclusion and exclusion criterions as follow:
Detailed description
This study will be conducted on (100) pregnant women diagnosed as placenta previa by ultrasonography and are candidates for either emergency or elective repeated cesarean section or hysterectomy (if the diagnosis of placenta accreta is confirmed). Those patients are attending to Kasr-Al Ainy Obstetrics outpatient clinic or casualty department during their 3rd trimester. Ultrasound and doppler will be done to all patients to diagnose placenta accreta . The diagnosis will be confirmed by intraoperative assessments and histopathological examination of the uterus after cesarean hysterectomy
Interventions
DIAGNOSTIC_TESTultrasound and doppler
• Ultrasound examination (2D gray scale and color doppler ) 1\. Confirming the presence of placenta previa 2,To assess the possibility of concomitant placenta accreta (Sonographic findings that have been associated with placenta accreta (1) Loss of normal hypoechoic retroplacental zone (2) Multiple vascular lacunae (irregular vascular spaces) within placenta, (3) Blood vessels or placental tissue bridging uterine-placental margin, myometrial-bladder interface, or crossing uterine serosa1 (4) Retroplacental myometrial thickness of 1 mm (5) Bladder wall interruption (6) Presence of placental bulge (7) Utero-vesical hypervascularity (8) presence of lacunae feeder vessels. 3\. Assessment of uterine artery Doppler in different cases of placenta previa. . Documentation of the operative findings during cesarean section and/or cesarean hysterectomy procedures. Histopathological examination of the hysterectomy specimens to assess the degree of myometrial invasion.
