Study of arterial pattern of normal human placenta in reference to its shape, weight and Hyrtl’s Anastomosis
Abstract
Background: Study of placenta in reference to its blood supply is very important for the reason that it is highly vascular organ which directly influences the growth and development of foetus. The shape of placenta, its weight together with Hyrtl’s anastomosis also directly or indirectly affects the health and wellbeing of the foetus.
Material & Method: 104 placentae were collected from Labour room, Gynaecology & Obstetrics Department and Lady Loyal Hospital. After cleaning and morphometry, Barium Sulphate was injected in the vascular tree of the placentae. Finally after radiography, observations were recorded.
Results: dispersed pattern of Arterial pattern was found in 72.88 percent placentae and in remaining 27.11 percent, Magestrial pattern was present. Average weight of placentae in the study was 468.4 gm. Hyrtl’s anastomosis was present in 100 out of 104 placentae.
Conclusion: study of vasculature of Placentae revealed that percentage of dispersed and magestrial pattern of placentae in north Indian population is not same as that reported in other studies of different regions.
