Anastomotic colonic varices after colectomy treated by obliteration via a transhepatic portal approach: A case report

Figure 5 Angiography. A: The catheter was advanced via the ileocolic vein into the marginal vein, and positioned at the right aspect of the anastomotic varices. Balloon-occluded retrograde venography demonstrated that the variceal drainage extended beyond the previously placed endoscopic clips and drained toward the inferior mesenteric vein; B: Selective occlusion of the two efferent draining veins, achieving unilateral flow control and directing the sclerosing agent into the targeted variceal complex; C: Final angiography demonstrated complete disappearance of the anastomotic varices and elimination of the previously visualized outflow tract, confirming successful obliteration.
