Percutaneous electrothrombosis: a minimally invasive technique for the treatment of deep hemangiomas.
BACKGROUND
A percutaneous electrocauterization technique for the treatment of deep hemangiomas is introduced as an alternative and minimally invasive treatment mode.


METHODS
Percutaneous electrothrombosis was applied through a needle-catheter that is a small silicone catheter with a needle guide in it. Thus, it is possible to do needle-point monopolar electrocauterization only at the needle tip because of the insulation of the other parts of the needle by the silicone catheter. By retracting the needle with catheter on it during electrocauterization, electrothrombosis was achieved through and around the channel of the needle, leaving vascularized tissue areas between the channels to perfuse the skin or mucosa covering the hemangioma.


RESULTS
This technique was applied as a single treatment or before surgery for the treatment of cavernous hemangiomas to more than 40 patients. However, adequate documentation was found for only 10 patients. After percutaneous electrocauterization of deep hemangiomas, discrete areas of skin necrosis appeared in some patients during the healing period, but the subsequent debridement and surgical excisions were easier because of the thrombosis effect of the technique due to the diffuse denaturation and fibrosis through and around the electrocauterization channels. The follow-up period was 1-13 years.


CONCLUSIONS
The proposed percutaneous electrocauterization technique for the treatment of deep hemangiomas achieved four effects: (1) volume reduction, (2) bleeding reduction, (3) anesthesia time reduction, and (4) cost reduction. The technique can be defined as a minimally invasive and effective alternative treatment for deep hemangiomas.
