I had the HAE procedure completed on 6/1. I was extremely nervous. The nurses, staff and doctor were attentive and were great at explaining what to expect which helped my anxiety. Everyone was so kind. Nurse IVY was very soothing as well as the nurses who worked with Dr. Loehr to complete the procedure. The mild sedation is very calming and will put your nerves at ease. I’m still in my healing phase but I already notice a difference with hemmroid bleeding. I will update my review as time passes on. Thank you so much to the staff at Triangular Vascular.
