[Hemodynamic disorders resulting from angiography (selective arteriography of the celiac trunk and splenoportography) (author's transl)].

The hemodynamic disorders resulting from the selective arteriography of celiac trunk and splenoportography were studied in 30 dogs. The systemic blood pressure and peripheral pulse rate were considered in these instants: before, during, immediately after and 10 minutes after the angiographic procedures. The analysis of the results obtained permit to conclude that: a) catheterism of the celiac trunk only, increase the systolic systemic blood pressure but does not change the dyastolic; b) during the injection of the contrast medium in the celiac trunk there is an increase of the systemic blood pressure (systolic and dyastolic); c) the selective arteriography of the celiac trunk as well as the splenoportography cause decrease of the systemic blood pressure (systolic and dyastolic) immediately after (1 to 70 seconds) the procedure; d) the decrease of the systemic blood pressure (systolic and dyastolic) is greater after the arteriography than after the splenoportography; e) the decrease of the systemic blood pressure (systolic and dyastolic) is transitory; 10 minutes after the realization of angiographies the systemic blood pressure return to the values observed before the examination; f) selective arteriography of the celiac trunk as well as splenoportography cause decrease of the peripheral pulse rate 10 minutes after the realization of the angiographic procedures.
