Transluminal Coil Embolization of an Inferior Gluteal Artery Aneurysm by Ultrasound-guided Direct Puncture of the Target Vessel

AbstractPseudoaneurysms of the inferior gluteal artery are rare. We describe a case of an inferior gluteal pseudoaneurysm that presented as a painful mass in the buttock. A percutaneous thrombin injection under ultrasound guidance failed to occlude the sac, probably due to the wide neck of the aneurysm. Subsequently, transluminal coil embolization by ultrasound-guided direct puncture of the inferior gluteal artery achieved complete thrombosis of the sac. Ultrasound-guided coil embolization is recommended in the treatment of peripheral aneurysms where catheter placement using conventional interventional procedures is difficult
