Purpose: this study, using verapamil, a slow calcium channel blocker, was a randomized, clinical, double blind and placebo controlled trial, whose objective was to observe if there was a uteroplacental and fetoplacental flow variation during its chronic oral use. Methods: 123 patients were accompanied: study group (n = 61), submitted to verapamil 240 mg/day and control group (n = 62), submitted to placebo. These patients were randomized into groups of four women and treatment or placebo was given for thirty days. A flow examination of the uterine arteries and umbilical artery through doppler-velocimetry was recorded. The values of resistance (RI) and pulsatility index (PI) and of the systole/diastole ratio (S/D) of the arteries were compared after the drug administration calculating means and standard deviations. Results: the verapamil group showed RI = 0.82 (0.28), PI = 1.06 (0.12) and S/D = 2.42 (0.51) in the uterine arteries. The placebo group showed RI = 0.75 (0.35), PI = 1.00 (0.18) and S/D = 2.30 (0.38). When we analyzed the umbilical artery, the verapamil group showed RI = 0.73 (0.12), PI = 1.04 (0.13) and S/D = 2.94 (0.32). The placebo group showed RI = 0.70 (0.14), PI = 1.03 (0.07) and S/D = 3.02 (0.78). The statistical analysis of the differences of the means by the F ratio showed that there was no difference between these two groups. Conclusion: this study indicates the use of verapamil for chronic hypertensive pregnants since it does not provoke damage to the uterine and fetal blood flow.

Aplastic anemia is characterized by a circulating pancytopenia, hypocellularity, and fatty replacement of cellular marrow elements, without evidence of malignant transformation or myeloproliferative disease. It usually affects young and senior adults, without any sexual preference. Most cases of aplastic anemia are acquired, but the disease may also be inherited due to a molecular disorder (Fanconi's anemia). Aplastic anemia in pregnancy is an extremely rare condition with high maternal and fetal morbidity and mortality rates. The authors describe a case of a patient with previously diagnosed aplastic anemia, whose pregnancy was complicated with urinary tract infection, preeclampsia and fetal growth restriction, with elective preterm birth. In spite of the adverse conditions in pregnancy and delivery, mother and newborn had a satisfactory clinical evolution.
