Embolization of a Previously Excluded Symptomatic Internal Iliac Aneurysm Through the Iliac Vein.

A 69-year-old man was referred urgently for a 58-mm enlarging painful right internal iliac artery (IIA) aneurysm. Since exclusion through proximal IIA coverage and distal IIA branches embolization had been previously performed, aneurysm sac puncture through the iliac vein was decided. The ipsilateral common femoral vein was antegradely punctured, and a 16.5 G Ross modified Colapinto needle from a transjugular intrahepatic access set was used to puncture the sac and fill the aneurysm with coils. Embolization of an IIA aneurysm through the iliac vein may represent an alternative when prior IIA aneurysm exclusion has been performed.
