RESUMO
OBJECTIVE: This study evaluated the Digene HPV Assay Hybrid Capture System(R) as a triage method. METHODS: Results of an HPV assay were compared with a final tissue diagnosis of cervical intraepithelial neoplasia 2 (CIN2) or greater. These results were stratified based on Pap smear diagnosis and evaluated in 4 triage algorithms. RESULTS: Of the 4 algorithms evaluated, the highest savings came from not performing colposcopy for patients with repeat atypical squamous cells of undetermined significance (ASCUS), but that resulted in missing nine patients with CIN2 and CIN3 histology. HPV testing failed to diagnose 67% (6 out of 9) to 48% (10 out of 21) of patients with underlying CIN2 and CIN3. CONCLUSIONS: Although HPV high-risk positive results correlate with high-grade histology, it is associated with significant false negatives. The HPV low-risk test is not clinically useful. These tests were poor methods to triage patients in our population.
RESUMO
Amniotic fluid (AF) embolism is a rare but catastrophic complication of pregnancy. We present the first case where the debris was seen in the maternal uterine veins at the time of cesarean section. During a cesarean delivery performed for deteriorating fetal status and in conjunction with massive hydramnios; air bubbles and vernix were observed in the left uterine vein and in an area of Couvelaire appearance of the uterine fundus. As the patient was clinically stable and desired retained fertility, a decision was made to attempt to contain the debris in the uterine vasculature. The infundibulopelvic ligament and uterine arteries were ligated and the area of Couvelaire uterus was oversewn. With the exception of a mild laboratory coagulopathy, which required no specific treatment, the patient did well. The area of Couvelaire uterus is the likely portal for the debris seen in this patient's vasculature. Containment appears to have averted the AF embolism syndrome.
