INTRODUCTION:
Surgical treatment for hemorrhoids should be indicated individually and is based on the predominant symptom (bleeding or prolapse), severity of disease and the presence or absence of external component (plicoma). Surgeons must choose among varied techniques the one suitable for each case.

TECHNIQUE:
The THD procedure consists of Doppler guided high ligation, selective to up six submucosal arterial branches that supply the hemorrhoids, leading to its desarterialization associated with prolapse repair (anorectal repair or lifting). It uses special equipment and kit.

CONCLUSION:
THD technique has shown good initial results. Because surgical technique respects the anatomy, it acts directly on the pathophysiology of the disease and corrects its principal consequences; it looks quite promising. Its initial application may be in patients with hemorrhoids grade II, which have surgical indication, grades III and IV, the latter being associated with resection of plicomas.
