Uterine compression sutures in controlling postpartum haemorrhage: A narrative ...
Moleiro, ML; Braga, J; Machado, MJ; Guedes-Martins, LIntroduction: Postpartum haemorrhage is still the main cause of maternal morbidity and mortality. Many treatments are available, but they may threaten fertility potential. As a uterine sparing procedure, we aimed to review uterine compression sutures in order to better understand when they should represent an appropriate option. Material and Methods: A comprehensive search in MEDLINE and PubMed databases includ...
Uterine artery impedance during the first eight postpartum weeks.
Guedes-Martins, L; Gaio, AR; Saraiva, J; Cunha, A; Macedo, F; Almeida, HThe aim of this study was to construct reference ranges for the uterine artery (UtA) mean pulsatility (PI) and resistance (RI) indices from 1-8 weeks postpartum. A prospective, cross-sectional, and observational study was performed with 320 healthy women from week 1 through week 8 postpartum. UtAs were examined transvaginally using colour and pulsed Doppler imaging, and the means of the right and left values of...
Reference Ranges for Uterine Artery Pulsatility Index during the Menstrual Cycl...
Guedes-Martins, L; Gaio, R; Saraiva, J; Cerdeira, S; Matos, L; Silva, E; Macedo, F; Almeida, HBACKGROUND: Cyclic endometrial neoangiogenesis contributes to changes in local vascular patterns and is amenable to non-invasive assessment with Doppler sonography. We hypothesize that the uterine artery (UtA) impedance, measured by its pulsatility index (PI), exhibits a regular pattern during the normal menstrual cycle. Therefore, the main study objective was to derive normative new day-cycle-based reference r...
Fetal-maternal interface impedance parallels local NADPH oxidase related supero...
Guedes-Martins, L; Silva, E; Gaio, AR; Saraiva, J; Soares, AI; Afonso, J; Macedo, F; Almeida, HBlood flow assessment employing Doppler techniques is a useful procedure in pregnancy evaluation, as it may predict pregnancy disorders coursing with increased uterine vascular impedance, as pre-eclampsia. While the local causes are unknown, emphasis has been put on reactive oxygen species (ROS) excessive production. As NADPH oxidase (NOX) is a ROS generator, it is hypothesized that combining Doppler assessment...
Relationship between body mass index and mean arterial pressure in normotensive...
Guedes-Martins, L; Carvalho, M; Silva, C; Cunha, A; Saraiva, J; Macedo, F; Almeida, H; Gaio, ARBACKGROUND: Being overweight is associated with both higher systolic blood pressure (SBP) and diastolic blood pressure (DBP) during pregnancy and increased risk of gestational hypertensive disorders. The objective of this study was to determine and quantify the effect of body mass index (BMI) on mean arterial pressure (MAP) at several time points throughout pregnancy in normotensive (NT) and chronic hypertensiv...
Internal iliac and uterine arteries Doppler ultrasound in the assessment of nor...
Guedes-Martins, L; Cunha, A; Saraiva, J; Gaio, R; Macedo, F; Almeida, HThe objective of this work was to compare Doppler flows pulsatility index (PI) and resistance indexes (RI) of uterine and internal iliac arteries during pregnancy in low risk women and in those with stage-1 essential hypertension. From January 2010 and December 2012, a longitudinal and prospective study was carried out in 103 singleton uneventful pregnancies (72 low-risk pregnancies and 31 with stage 1 essentia...
