Brief summary
In this study , safety and efficacy of superior rectal artery embolization with embospheres will be researched prospectively.
Detailed description
Symptomatic hemorrhoidal disease is a still important public health problem although there are many surgical and nonsurgical minimal invasive treatment methods. Treatment methods are not satisfactory or invasive in some percent of the patients. Superior rectal artery embolization(SRAE) for hemorrhoids is an adapted technique derived from Doppler-guided hemorrhoidal artery ligation (DGHAL). In this technique, the distal branches of the superior rectal artery arising from the inferior mesenteric artery is occluded endovascularly with coils. Its feasibility and safety were supported by articles. Collateralization and recurrence was seen following coil embolization. To prevent this , tri-acryl gelatin microspheres in 500-700 and 700-900 micrometers in size will be used. Safety and efficacy of embolization and using different sized particles will be evaluated.
Interventions
Left, right and posterior branches of superior rectal artery will be embolized with tri-acryl gelatin particles in 500-700 and 700-900 micrometers in size until homeostasis will be achieved.
