RESUMO
Placental scintigraphy was performed on 367 pregnant women over seven years. Indications were prepartum bleeding in 200 patients, Rh incompatibility in 111, and other types of high-risk pregnancy in 56. Nuclide113m In Cl3 was primarily used, with a scintillation camera being used for scintigraph recording. The sensitivity accounted for 98 per cent. The placenta was found to stick to the fundus or other parts of the uterus in 280 cases or in deep positions in 37 cases. It was partially existent in 27 cases and totally existent in 16 instances. Placenta praevia had been the cause of prepartum bleeding in 17 per cent of the patients checked, in that context. Abnormal foetal presentations were recordable more often from those cases, but rates of malformation were not increased. Clinical retention time and mode of delivery were found to depend on both obstetric results and position of the placenta. - Dependable findings with regard to localisation prior to the 28th week of pregnancy were scintigraphically obtainable only from 82 per cent of all cases, which figure went up to the order of 91.2 per cent in response to scintigraphy as of the 35th week of pregnancy. - The scintigraphic findings recorded from 209 patients were rechecked and verified in 193 cases, bringing the accuracy to 92.4 per cent.
