catheter was used to subselect the origin of the inferior mesenteric artery. Next, with the help of a true form wire, a 2.9 merit microcatheter was now advanced into the inferior mesenteric artery used to subselect the left colic artery and further into the sigmoid artery. A sigmoid artery angiogram was now performed which demonstrates multiple superior rectal branches that extend towards the anal rectal region specifically supplying the hemorrhoids.

At this point, the 2.9 merit microcatheter is used to subselect a single left-sided and 3 right-sided superior rectal arteries where a total of six 3 mm coils are deposited. On the right side, a decision is made to embolize with particles. A standard 700 to 900 µm Embosphere particle mixture is made with 10 cc of contrast. A total of 2 cc is used to embolize the right superior rectal arteries at the very distal aspect of the superior rectal arteries in order to allow for distal embolization

do we use cpt 37242 for this & what cpt is simoid angio? Pls help
