Images of the ideal nodules for RFA. spongiform nodules shrink the most.
They are the least likely to be cancers.
In the future, RF ablation could be a promising minimally
invasive technique for the treatment of benign thyroid
nodules and recurrent thyroid cancers. RF ablation could
also be used for inoperable patients with primary thyroid
cancers. For safe and effective RF ablation, the operators
should be aware of the US anatomy of critical structures in
the neck as well as various techniques and devices used for
thyroid RF ablation.
Although esophageal or tracheal injury, heart problems
caused by the RF current, and thermal injury to critical
structures in the neck such as the cervical sympathetic nerve
and spinal accessory nerve have not been reported, the
operator should be aware of the significance of such possible
complications, especially when a recurrent tumor is close to
Therefore, a combination of ethanol and RF ablation can be
considered as the one of the successful treatment options for
RF ablation is a safe and effective alternative to surgery
for treating benign, nonfunctioning, or autonomously functioning
nodules as well as for recurrent thyroid cancers.
Its efficacy can be maximized by complete ablation of the
entire tumor margin, which is essential in order to prevent
marginal regrowth and to effectively reduce the size of
thyroid nodules. And in order to minimize the possibility
of complications, it is important to consider the broad
spectrum of possible complications as well as the available
