简要总结

In this study , safety and efficacy of superior rectal artery embolization with embospheres will be researched prospectively.

详细描述

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.

研究组 & 干预措施

Embospheres 500-700 microns

Experimental

Intervention.Embolization with 500-700 micron particles will be performed with 1 ml vials. Embolization procedure will be continued with vials until the stasis in SRAE will be achieved. Procedure will be performed only one time.
