Experimental popliteal vein thrombosis.
A device for experimental popliteal vein 'thrombosis' was developed and tested on a group of eight normal volunteers. Scintigraphy of the vessels and plethysmographic venous emptying recordings were performed as test procedures. The experimental set-up consisted of a syringe piston connected to a manometer and pump. A graded pressure was exerted on the dorsal aspect of the vein visualized with gamma-camera after in vitro labelling of the autologous red blood cells with 99Tcm. The position of the piston was controlled with a cobalt marker. The device proved successful and may be used when evaluating noninvasive diagnostic methods for detecting deep vein thrombosis and studying the haemodynamic consequences of acute venous thrombosis.
