Placental vascular tree at sea level

Descripción del Articulo

Objective: To determine the morphology and weight of the placental vascular tree. Material and Methods: Twenty seven placentas were collected from normal pregnant women who had prenatal care at Clinica Villa Maria–EsSalud. Patients who had diabetes mellitus, arterial hypertension, preeclampsia, neph...

spelling Placental vascular tree at sea levelArbol vascular placentario a nivel del marMartina, M.Rosales, H.Malca, T.Delgado, F.Anchiraico, E.Torres, M.Rengifo, C.Quisocala, D.Gutiérrez, M.Pérez, E.Herrada, T.Objective: To determine the morphology and weight of the placental vascular tree. Material and Methods: Twenty seven placentas were collected from normal pregnant women who had prenatal care at Clinica Villa Maria–EsSalud. Patients who had diabetes mellitus, arterial hypertension, preeclampsia, nephropathy, Rh isoimmunization and anemia were not included. The specimens were rinsed with tap water for 30 minutes, the fetal membranes were trimmed off at the level of its insertion. The placentas were weighed and the umbilical vessels were catheterized and flushed with 100 mL of normal saline solution and then the acrylic solution (15 mL of liquid with 7,5 of powder) was injected. The placentas were immersed in hot water for 30 minutes then fixed in 10% formaldehyde for two hours and finally immersed in hydrochloric acid for 7 days in order to obtain the acrylic cast of the placental vascular tree by corrosion. Results: The mean weight of the vascular tree was 16,9 g (8,7-25,3 g). The mean placental ratio was 0,1571 (0,1081-0,1944) and the mean placental vascular ratio was 0,0317 (0,0230-0,0560); in addition there was a direct relation between the weight of the placenta and the weight of the vascular tree. Conclusions: Our data will permit comparison with high altitude placentae, where hypoxia could modify placental vascular tree.Objetivos Determinar la morfología y el peso del árbol vascular placentario a nivel del mar. Material y Métodos: Se seleccionó al azar 27 placentas, cuyas madres cumplían con los criterios de inclusión (CPN, ausencia de diabetes, hipertensión arterial, preeclampsia, nefropatías, isoinmunización Rh). Obtenida la placenta se procedía a lavado por 30 minutos con agua potable, corte de membranas al ras del borde placentario, corte del cordón umbilical a 5 cm de su inserción, cateterización de los vasos umbilicales, lavado con 200 cmL de solución salina 9º/oo, se inyecta solución de acrílico, curado lento, a presión conocida 15 mL de solución y 7,5 g de polvo acrílico, teñido de rojo para las arterias y de azul para la vena. Sumersión en agua hervida por 30 minutos, luego formol 10% por dos horas y ácido perclórico (ácido muriático) por siete días. Se rociaba las placentas con agua y se obtenía el árbol. Resultados: El peso promedio del árbol vascular placentario fue 16,9 g, rango: 8,7–25,3 g; el índice placentario fue: 0,1571, rango: 0,1081–0,1944 g y el índice vascular placentario 0,0317, rango: 0,0230–0,0560. A mayor peso placentario, mayor peso vascular placentario. Conclusiones: Los datos obtenidos, servirán de comparación con los resultados a obtener en placentas de altura, a fin de determinar si la hipoxia de altura incrementa la vasculatura placentaria.Sociedad Peruana de Obstetricia y Ginecología2015-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.spog.org.pe/web/revista/index.php/RPGO/article/view/47510.31403/rpgo.v47i475Revista Peruana de Ginecología y Obstetricia; Vol. 47, Núm. 1 (2001); 53-572304-51322304-5124reponame:Revista SPOG - Revista Peruana de Ginecología y Obstetriciainstname:Sociedad Peruana de Obstetricia y Ginecologíainstacron:SPOGspahttp://www.spog.org.pe/web/revista/index.php/RPGO/article/view/475/442info:eu-repo/semantics/openAccess2021-05-03T15:50:58Zmail@mail.com -
