[Surgery of abdominal aortic aneurysm infra-renal. Hemodynamic changes induced by aortic clamping and declamping. Eight cases (author's transl)].
Hemodynamic data of 8 patients undergoing planned resection of abdominal aortic aneurysm are statistically analyzed by variance analysis ("patient" factor and "time" factor). The results are: 1. "Patient" factor exists for all the variables studied. 2. "Time" factor is present for some of them. After aortic clamping, there is a significant decrease of the systolic index (p less than 0.05) and of the left ventricular systolic work index (p less than 0.01). After aorting declamping, a high significant increase of the mean right auricular pressure (p less than 0.001) and of mean capillary wedge pressure (p less than 0.001) are seen. Similar results are observed at the end of surgery. The results are commented with regard of the literature.
