At the Department of Obstetrics and Gynecology in Helsingborg, the experience has differed somewhat from what was found at Silkeborg Central Hospital in Denmark concerning vacuum aspiration tissue. The amount of tissue aspiration from 1902 patients was investigated in the same way. In agreement with the Danish authors, it is concluded that a relationship exists between tissue quantity and gestational age and that a range exists in the various groups, though not to the same extent as they found. The mean quality of tissue taken from 1902 was measured and then the range in 488 patients from the previous year was studied. 8 reevacuations were performed, all with primarily less tissue than expected and all with placental tissue on the 2nd occasion. 9 of 33 patients with an infection postabortum also had less tissue than expected. The total infection rate was 6.3%. 1 case of ectopic pregnancy was found, accidentally discovered at sterilization performed on the same occasion as the vacuum aspiration. In sum, a definite relationship was found between tissue quantity and gestional age, but the range in tissue quantity was not to the same extent as with the Danish material.
