[Use of an electric field for experimental thrombosis of vessels and arterial aneurysms].
Two series of experiments with canine arteries were conducted with the employment of extravascular electrodes, I volt power and I to 2500 micronA current. With a current up to 500 micron A, as well as with the optimum current (2000-2500 micronA), but with an over 3.5 mm diameter of the vessel no complete thrombosis is achieved. This, according to the author, is due to the flow rate and power of the electric field created. The critical flow rate that permits to achieve electrothrombosis of an artery, is 250-300 ml/min. Electrothrombosis of artificial aneurysms permits to achieve their obstruction rather promptly. The optimum time of thrombosing is 40-60 min with a 2000-2500 micronA current. Any further exposure to the electric field does not result in thrombosis of the vessel in question.
