[Use of an automated venous occlusion plethysmograph for late postoperative studies on the arterial blood flow of the leg after use of the external iliac artery for retrograde perfusion].

The authors report on a new segment plethysmograph by help of which quick and completely automatic measuring of top flow is possible in high quality. The device is present as model for laboratory use and has proven good in practice. It was used, e.g., for the control of arterial blood supply in legs of patients who years ago were perfused via an external iliac artery during open heart surgery. Corresponding with the clinical findings, also by plethysmography no statistically significant differences of blood flow values were found in the legs with perfused or non-injured arteries.
