Massive Pelvic Hematoma After Atrial Septal Defect Closure Via Femoral Vein Cannulation.

We report a rare case of pelvic hematoma caused by iatrogenic external iliac artery hemorrhage following transfemoral venipuncture for atrial septal defect closure. By means of urgent femoral arteriography, bleeding in the branches of the external iliac artery was confirmed and occlusion of the bleeding branches was performed, thus avoiding the need for surgical laparotomy. The patient recovered well, and the hematoma significantly was reduced 2 months after surgery.
