ACUTE OCCLUSIVE COMPLICATION IN DIAGNOSTIC CATHETERISATION OF ARTERY OF EXTREMITY

1) Twenty four operated cases of acute arterial osslusion after diagnostic catheterisation were reviewed. The incidence of the complication is roughly calculated at 0.3%. Of risk factors of the complication, personal technique and/or personality of the examiners is one -potent factor. As the occlusion is caused by traumatic catheterisation, not only simple thrombectomy but repair of damaged wall is necessary for operative procedure, The operations rescued both legs and arms of all cases but 2 necrotic legs emerged in 2 later cases.
2) Evoked potential of calf muscle by electric stimulation of sciatic nerve of the rabbits was observed. By both aortic and femoral clamp of artery, the potential was reduced and disappeared within 15 minutes, which recoveed promptly by declamping after 60 minutes of clamping. The potential, during the observation of 90 minutes with aortic clamp, was only half reduced and recovered little by declamping. These results are consistent with such clinical observation of the authors that in cases with multiple locations of the occlusion the symptomatic onset was generally more rash than with single location and, multiple or simple, the earlier operations produced the better recovery of extremities.
