[Intraoperative Doppler testing of the efficacy of correcting the valves of deep veins with a framework coil]

The ultrasonic dopplerography was used in 37 patients as control of correction of profound vein valves. Local anesthesia was used in 12 patients, general anesthesia was used in 25 patients. The first group of patients performed the Valsalva test themselves, in the second group it was substituted by manual compression of the frontal abdominal wall. The results obtained show that intraoperative dopplerography allows methodological and technical errors to be corrected during the operation. The control is found to be more effective provided that the patient performs the Valsalva test himself during correction of the valve. The routine method of selection of the spiral diameter is thought to be fairly rational.
