Key result
Changing the size and position of electrodes during Transcatheter Electrocoagulation in dogs did not affect the time required for vessel occlusion, though voltage requirements varied.
Should not yet inform electrode protocols in patients; leaves open translation of canine transcatheter electrocoagulation findings to clinical use.
The effect of changing the size and position of the anode and cathode during direct current Transcatheter Electrocoagulation (TCEC) was evaluated in dogs. The results showed that there was no difference in the time required for vessel occlusion when the size and position of the electrodes were changed. However, there were differences noted in the amount of voltage needed to maintain the constant current. Based on these results, for TCEC we recommend positioning the largest possible guidewire anode against the vessel wall. The cathode should be a highly lubricated sponge covered Bovie ground plate.

Hirschfeld et al. (1981) studied this question. Changing the size and position of the anode and cathode was evaluated on Time required for vessel occlusion. Changing the size and position of electrodes during Transcatheter Electrocoagulation in dogs did not affect the time required for vessel occlusion, though voltage requirements varied.
