[Treatment of post-thrombotic syndrome by technic II of valvular substitution at the popliteal vein. Results of measurements of peripheral venous pressure compared before and after intervention].
The modified technique II of the substitute valve operation consist in using a 24 cm long silicone-tendon. Its medial end is sutured with the 3 cm long gracilis tendon, drawn between popliteal artery an vein, and its lateral end is sutured around the biceps tendon. The fixed length of the silicone-tendon and its gliding ability are two advantages, which simplify the operation. The efficacy of the substitute valve using the technique II is controlled clinically and phlebographically, whilst the amelioration of the venous haemodynamics ist documented additionally by means of the comparative venous pressure measurements before an after the operation. Before operation was Ps = 100,5 mmHg, Pg1 = 79,0 mmHg and delta P1 = 21,5 mmHg. After operation was Ps' = 99,3 mmHg, Pg' = 33,8 mmHg and delta P' = 65,5 mmHg.
