Study Notes
C-Section Complications and Surgical Interventions
- Hysteroscopy allows visualization of the inner uterine cavity and can repair previous uterine ruptures.
- Uterine dehiscence after a C-section increases the risk of repeat ruptures during future pregnancies.
- Hysteroscopic resection may unintentionally create myometrial weakness.
- Complications from prior C-sections may manifest 1-2 weeks earlier than the previous event.
Ectopic Pregnancy
- Types include ampullary and cervical ectopic pregnancies.
- Deep cornual resection addresses interstitial ectopic pregnancies.
Abruptio Placenta
- Hypoxia-related factors can influence abruptio placenta, including maternal nicotine and cocaine use.
- Abruptio placenta can cause micro-infarctions in the placenta, leading to thrombus formation.
- In 2019, classifications of abruptio placenta based on severity were proposed, highlighting medical understanding.
Clinical Features of Placenta Previa
- Characterized by painless vaginal bleeding that may occur without uterine contractions.
- Can lead to significant bleeding, particularly if the placenta covers the internal os.
- Often diagnosed using transabdominal and transvaginal scans to locate the placenta.
Pathology and Diagnosis of Placenta Previa
- Defined as premature separation of an abnormally positioned placenta.
- Diagnosis follows any mid-pregnancy vaginal bleeding; digital examinations are contraindicated.
Placental Migration and Risk Factors
- Typical placental growth trends towards the fundus; misnomers around "placental migration" exist.
- Risk factors for placenta previa include advanced maternal age, higher parity, and history of uterine surgeries.
Imaging and Observation
- Close monitoring of high-risk pregnancies is crucial, particularly for patients with placenta previa.
- Early admission is recommended to manage potential hemorrhage risks.
Case Studies and Differential Diagnosis
- Abruptio placenta display hemorrhages along the serosal areas during operative findings.
- Key clinical signs for abruptio placenta include sudden abdominal pain and unusual fetal heart monitoring results.
- Accurate diagnosis is critical in differentiating between conditions like uterine rupture and placenta previa, based on clinical presentation and examination findings.
