Fig. 10. A 67-year-old female with a history of metastatic colorectal cancer who has a past surgical history of low anterior resection and diverting sigmoid colostomy. She subsequently developed portal hypertension and stomal varices (arrow) after undergoing multiple microwave ablation procedures for recurrent liver metastases. (A) Axial fat-suppressed T1-weighted contrast enhanced images demonstrate multiple serpiginous tubular varices within the region of the stoma (arrow). (B) Ultrasound-guided access of a prominent stomal varix was obtained and catheter-directed coil embolization was performed of prominent feeding mesenteric collaterals. (C) Post-procedural coronal computed tomography image demonstrates resolution of stomal varices (arrow) but aggravation of ascites.
